technical field

The present disclosure relates generally to optical components, and more particularly to methods and systems for making functional plastic films, functional polymer films, functional polyvinyl alcohol (PVA) films or functional polyethylene terephthalate (PET) films.

background

It is well known that ultraviolet (UV) light can cause severe glare on the cornea in high-intensity light sources. Therefore, you may need to protect your eyes from these harmful UV rays. Eye protection may be required during welding, when exposed to sunlight at altitudes above 5,000 feet (1524 m) above sea level, or when sunlight is reflected in snow, water or tanning.

Infrared (IR) light can also be harmful. Natural sources such as wireless communications, appliances, computers, lighting, and sunlight can emit varying levels of harmful radiation. Infrared (IR) can account for more than half of sunlight's thermal spectrum radiation. At sea level, sunlight can provide about 1 kilowatt of irradiance per square meter at sea level, of which 527 watts are IR radiation. When sunlight reaches Earth's surface, almost all thermal radiation can be infrared.

The energy of sunlight reaching the ground can be classified as about 3% ultraviolet, 44% visible, and 53% infrared. Therefore, prolonged exposure to intense sunlight without protection can cause a stinging or stinging sensation in the eyes, often accompanied by fatigue. This discomfort can be particularly noticeable to contact lens wearers, as contact lenses can "warm up" by absorbing infrared radiation. An ophthalmologist may recommend getting into the habit of wearing sunglasses if you are exposed to the sun for a long time.

Traditionally, protective lenses may be coated with one or more layers of infrared and/or visible dyes to block harmful light from light sources. In general, soluble dyes and/or metal oxide pigments that absorb or reflect specific frequencies of light (eg, infrared frequencies, ultraviolet frequencies, etc.) can be used in the coating. Thus, coated lenses can reduce or alleviate eye diseases such as cataracts and glaucoma.

Because of the importance of sunglass and spectacle protection, many coating technologies have been developed. IR or visible light coatings can be applied by dipping or spraying a solvent IR or visible light dye onto another optical layer of the lens. However, the curvature of most lenses can be a significant obstacle to the application of IR or visible light coatings as the application of the coating may be uneven, reducing the effectiveness of the protective layer.

Using traditional methods such as extrusion or injection, infrared or visible dyes may be added during the process. Extrusion is a process that can be used to manufacture objects of fixed cross-sectional profile. The material can be pushed or pulled through a die of the desired cross-section. In the plastic extrusion process, the plastic can first be melted into a viscous semi-liquid state. Once the plastic has softened, you can push it through the contoured hole. With this technique, a curved lens can be created by forcing a softened optical film through a contoured aperture.

Injection molding can be a manufacturing process in which a part is produced by injecting material into a mold. The material for the part is fed into a heated barrel, mixed, then forced into the mold cavity where it can be cooled and hardened to the configuration of the cavity. In the case of optical plastic film, regardless of the extrusion or injection method, heat can be used to soften the plastic film and make it into a curved shape. Since dyes are sensitive to heat, some dye degradation may occur, reducing eye protection.

Another problem with infrared or visible light coated lenses is that they are prone to scratches and are not resistant to chemicals or elements. Over time, the protective layer loses its effectiveness and can become harmful if not detected and replaced. To overcome this problem, lens manufacturers started spraying, dipping, or injecting other protective layers over the infrared/visible layers. However, adding layers can make the lenses thicker, which can become an obstacle to eyeglass design and fit.

In addition, conventional coating methods such as injection or extrusion may be aesthetically unappealing because the IR dye appears green. Gray can be added to the PVA film to offset or offset the undesirable green color. However, adding this gray reduces the transmittance of light, greatly reducing visibility. Lastly, adding gray to the PVA film of the lens can increase the cost of the lens and thus increase the cost of the final product. Therefore, materials and manufacturing processes for inexpensive and fast infrared absorbing lenses may be desirable.

Recently, a solution casting method has been invented and preferred to overcome the disadvantages of extrusion and injection methods. This manufacturing technology can be unique in that it can easily integrate components and functions traditionally produced by these processes without the need for traditional extrusion or injection molding techniques. This method uses a mandrel or bore mold immersed in a polymer solution or liquid plastic tank designed specifically for the process. The combination of thermal and tribological properties causes the polymer solution to form a thin film around the mold. The mold can then be extracted from the tank in a precise and controlled manner, followed by a curing or drying process.

Other casting devices used in solution casting include belt or drum machines. Generally, the width of the support belt is 1.0 to 2.0 m, and the length is 10 to 100 m. The thickness of the stainless steel belt may be 1.0 to 2.0 mm. Drums are generally 4 to 8 m in diameter and 1.20 to 1.50 m wide. Belt channels may allow airflow to flow in either machine or counter-direction. The drum may be tightly sealed to prevent vapor escape and to direct airflow in the opposite direction to the drum movement. One of the two pulleys or drums can be connected to a drive that requires very precise speed control to avoid even slight speed changes. One drum is connected to a servo system that can adjust the belt tension to ensure constant flatness and 'absence' of belt movement (vibration) in a critical area just behind the casters, and to control expansion and expansion of the belt length due to temperature changes. can Belt machines may have a guide system to prevent the belt from shifting during operation. The belt can be guided by horizontal movement of the support drum. A variety of support materials have been used in belts, including copper, silver-plated copper, chrome-plated steel, stainless steel, metal coated with polyvinyl alcohol or gelatin, polyester films, polytetrafluoroethylene (PTFE) films, and other polymer films.

Currently, the most common support materials are stainless steel and chrome-plated surfaces. Critical items in belt and drum equipment are the thermal conductivity of the material, the technological process used to manufacture the required surface finish, and options for repairing small surface defects. Films with structured surfaces can be easily fabricated using this casting technique. The belt surface can be clearly and accurately replicated on one surface of the film. The technology used to apply the surface of the drum or belt to a high gloss, structured or matte film finish is a proprietary method.

Once the first layer of thin film has properly solidified, secondary features such as braided or coiled wire, laser cut hypotubes or engineered metal reinforcements to prevent tangling, or imaging targets specific to the intended medical application can be added to the product. . Multiple casting steps can then be repeated to encapsulate stiffeners, increase wall thickness, add lumens, and optimize column strength. The part is then cured or solidified before being removed from the mold. This method can be used with solvent polymers in liquid form without using excessive heat to cure the part. Because this method uses centrifugal force to shape the part, with the right flow rate, a very thin layer of IR or visible dye solution can be added to the optical film without using excessive heat.

Another method of producing films is static methods such as cavity molds, plate casting or other similar methods.

Some embodiments are described in detail with reference to the associated drawings. Additional embodiments, features and/or advantages will become apparent from the following description or by practicing the present application. The following description is not to be taken in a limiting sense and is prepared solely for the purpose of explaining the general principles of the present application. The steps described herein for performing the method constitute one embodiment of the application, and unless otherwise specified, not all steps must be performed in order to practice the application, and the steps must be performed in the order listed. Neither is it. It should be noted that references in this disclosure to “one” or “an” or “some” embodiments are not necessarily to the same embodiment, such references to at least one.

According to embodiments of the present application, the methods and systems for manufacturing functional films disclosed herein provide many significant advantages over the prior art. Specifically, the present application yields functional films that are substantially isotropic, flat, and dimensionally stable. Additionally, this functional film achieves maximum optical purity and extremely low haze. In addition, the film is dyed to precise specifications without being affected by dye degradation problems. As a result, current functional films are less prone to processing, defects, delamination, and stress, requiring fewer layers in optical lenses and shorter processing times. Although there are many advantages, the current method easily integrates and uses the mixing components used in the existing method. Current applications do not increase material costs and, in some cases, can actually reduce material costs because they reduce the number of layers of optical lenses by creating accurate optical properties, specifications and thinner thicknesses of functional films.

In one embodiment, low heat below 100° C. may be used to speed up the dissolution of the polymer in the solvent. However, in other embodiments, other polymeric materials such as TAC may not require heat to dissolve. The solution may be further processed to reach a solution required to produce a functional film having specific optical properties. The final polymer or PVA solution is then introduced into the casting device 303 as shown in the figure. In one embodiment, the final polymer or PVA solution is deposited onto the moving belt 304 via casters or spreaders 305. The polymer or PVA solution is dried and solidified by the air stream 306 flowing in the belt channel 307 relative to the direction of the moving belt. In other embodiments, it will be appreciated that the air stream 306 may flow in the direction of the moving belt. In addition, the drying air, its direction, belt speed, spacing of belt channels, etc. are preferably calibrated to achieve desired thickness, dryness and other characteristics of the functional film.

In a preferred embodiment, the film is introduced into a dry environment at a temperature of 40-150° C. and the functional film is continuously removed from a moving belt for further drying, processing, rolling or sheeting for storage until use.

Another scratch resistant optical glass 502 is laminated over the dyed functional film 501 to protect the IR/visible layer from scratches, chemicals and/or elements.

(glass lenses, goggle lenses, protective shield sheets),

It contains optional narrowband visible dyes that absorb unwanted emitted light, especially organic dyes in the film that improve sharpness, colorful contrast, low haze for better lens products.

and add at least one absorbed IR radiation of the solution cast film.

This application lens product reduces eye fatigue and increases visual comfort.

[In some other embodiments, the lens includes a solution cast function film or a plurality of solution cast function films, and polishes a convex or (ie) 0.0-1.5 mm deep layered film on top of the lens without damaging the function film. , the total lens thickness is zero. 2-10.0 mm and/or IR thin film with or additional 0.02-0.18 mm convex or 0.001-1.5 mm deep surface on top, with or without polishing, if one of the layers does not damage the functional film, the total lens thickness is 0.2 -10.0mm.

Most of the energy from the sun reaches Earth in the form of infrared radiation. Sunlight above the earth's atmosphere is composed of approximately 50% infrared, 40% visible and 10% ultraviolet (total energy basis) with an output of 1366 watts/m2. At ground level, this decreases to about 1120 to 1000 watts/m2, consisting of 44% visible light, 3% ultraviolet light (less when the sun is at its apex (directly overhead), but less at other angles), and the rest IR. Therefore, the composition of sunlight per square meter on the ground when the sun is at its peak is about 527 watts of infrared light, 445 watts of visible light, and 32 watts of ultraviolet light. The balance between absorbed and emitted infrared radiation has important effects on Earth's climate.

In natural light, the three main potential sources of eye damage are ultraviolet, visible blue, and near-infrared radiation. Too many types of radiation reach the earth at the same time.

Light waves from natural and artificial light sources can damage human eyes. Excessive exposure to harmful light can aggravate and cause irreversible damage to the sensitive areas of the eye.

Spectacle lenses are used to protect the eyes from excessive solar radiation, reduce eye strain and promote visual comfort. Standard lens treatment is applied with the aim of blocking harmful light by including colored dyes. This general treatment reduces the total amount of visual light transmitted through the lens and greatly reduces the sharpness that the human eye can see. The lens is still waiting for improvement.

A problem with prior art approaches is that they block a significant portion of visible light wavelengths, thereby lowering the visible light transmittance (VLT) through the lens or panel and adversely affecting the wearer's eyesight.

Wide bandwidth glasses have non-selective filter lenses that reflect light in a diffuse fashion.

Such a wide wavelength shielding film severely limits the wearer's field of view even in broad daylight. This problem becomes more pronounced as the level of visible light in the surrounding environment decreases. Reduction of visible light greatly affects the wearer's ability to perform certain functions, impairs depth perception, and impairs the ability to perceive certain colors.

Another alternative to manufacturing a protective filter or lens has been to coat the outer surface of the lens after the lens has been formed. This coating process greatly increases the cost of the lens and at the same time makes the coating too thin to be effective due to the absorbed selective dye. Thick coatings can make the layer uneven and crack.

Ultraviolet rays require special attention to protect human eyes. Even on cloudy days, wear sunglasses to reduce UV rays reaching your eyes. Ultraviolet light is invisible to our eyes and consists of three main wavelengths: UVA, UVB, and UVC. Unlike UVA radiation, which passes through the cornea to reach the lens and retina, UVB radiation is mostly absorbed by the cornea (the outermost layer in the front of the eye) and does not penetrate the retina. Ultraviolet light is filtered out by Earth's atmosphere. Table 1 below shows the three main components of the UV spectrum.

Table 1: UV spectrum

(Ultraviolet Dyes) Ultraviolet (UV) and visible (Vis) dyes can be incorporated into coatings, solutions and plastics. Since this radiation reaches the Earth, it is important to block ultraviolet (A) 315-400 nm. Current sunscreen technology is very sophisticated. It has been 40 years and can easily be applied to lenses. Of course, for lenses that can effectively block UV rays, you need the right UV powder and a good process. However, short-wavelength blue light and blue and purple photons are short-wavelength, so molecules can easily absorb them. The molecule holds the photon for a short time and then releases it again in a random direction. This is why the sky looks blue. Many of these scattered photons fly toward Earth, making the sky appear to glow. It can also damage a person's eyes.

Blue light is generated from both natural light sources (sunlight) and artificial light sources (screens, LED lights, home appliances, etc.). Exposure to blue light can cause eye strain and fatigue, and can trigger a series of chemical reactions that cause irreversible degenerative damage to the photoreceptor cells in the retina.

400-455nm blue light, which emits more neon violet blue, is easily scattered, causing visual fatigue and blurred vision. The plurality of organic dyes include blue absorbing organic dyes having a blue light absorption peak in the range of 400-455 nm. For special needs to block 400-495nm blue light for special tasks, visual needs or human preference, additional dye powder can be added.

In some cases, blue light can have serious and harmful effects on human eyes. Blue light wavelengths penetrate from 400 nm to 480 nm, and in particular, blue light close to purple from 410 to 430 nm contains almost no neon ultraviolet rays and has a greater effect on the eyes due to its shorter wavelength, so the light from 400 nm to 455 nm is the most harmful. Due to recent technological advances, the human eye is exposed to a larger amount of blue light throughout the day, and it is necessary to protect the eyes from this light spectrum.

The well-known technology of anti-blue light 400-455nm is broadband technology such as dyeing, dipping, injection, extrusion, film coating and coating. A wide bandwidth isn't sharp enough, which affects colors. Hue values and saturation also increase darkness.

Indigo's wavelength frequency range is approximately 425-450 nm, with a frequency of 670-700 terahertz (THz). Indigo can be considered a subset of purple. The color's low range explains why it is difficult to distinguish these colors in the spectral band. Since indigo is not scientifically recognized as a separate color, any wavelength less than 450 nm is considered purple.

Some embodiments may provide area enhanced contrast. The sun's maximum emission is around 580 nm, so blocking radiation at 580 nm may be beneficial. One embodiment of the present disclosure may include a novel high contrast method of providing anti-blue light lenses so that people can see clearly, easily, quickly and far.

If the frame is the skeleton of glasses, the lens is the soul of glasses, and the future of human eyes can be determined by the quality of lenses. Therefore, as an important line of defense for eye protection, we must consider the three main potential sources of human eye damage in natural light: ultraviolet light, blue light, and near infrared light.

Near-infrared exposure and cataracts: One of the most common eye diseases associated with near-infrared radiation is cataracts. Prolonged exposure to near-infrared light causes a gradual but irreversible clouding of the lens. Another form of eye damage caused by infrared exposure is ostomy, which is blindness due to damage to the retina. Even low levels of infrared absorption can cause symptoms such as eye redness, swelling, or hemorrhage. Infrared light penetrates clouds more strongly than visible light, so the transmittance is relatively high, so it can cause relatively large damage to the eyes. Cataracts caused by near-infrared radiation have historically been found in glass blowers and furnace workers. Radiation between 800 and 1200 nm is most likely to cause an increase in the temperature of the lens itself due to its spectral absorption properties. Visible wavelengths can also cause problems, as heat absorbed by the iris can transfer heat to the lens.

Coating methods with inorganic absorption of IR may include dye liquid immersion. This method may not be sufficient to absorb the radiation region of the N-IR spectrum, and viewers wearing such glasses may experience reduced sharpness.

When infrared radiation is absorbed, the temperature rises. Infrared rays are also imperceptible to the human eye. It may be important to recognize that light acts as a catalyst for the oxidation of substances, especially organics. The eye is particularly sensitive to thermal effects. Wearing appropriate protective goggles can protect your eyes from excessive exposure to infrared radiation. The biological effects of IR are primarily thermal effects. IR is easily absorbed by dark objects. High intensity IR induces tissue necrosis and protein coagulation. Far-infrared rays can only penetrate 0.5 cm to the left of tissue and are almost completely absorbed by the cornea and aqueous humor. Near-infrared rays can penetrate tissues up to 3 cm to reach the retina and are absorbed by pigments in the iris and retina.

Glass materials for glass lenses may have some infrared protection. Temperatures above 800°C are required to melt the glass and mix it with the rare earth IR absorbing dye. When the dye is damaged, it can only absorb radiation with wavelengths of 750 nm, 810 nm or 890 nm. Lenses can be made via injection or extrusion, but this process requires temperatures above 230°C, which can melt the polymer plastic, damage the dye structure and cause color degradation. In addition, the thickness of the lens must be at least 0.4 mm, and since the dye is sprayed on thick plastic, the concentration of the absorbent dye may decrease, which may deteriorate the function of the lens. Cast films may be used with extruded or cast substrates to maintain lens performance requirements and the requirement that haze (the fraction of incident light scattered through the lens) not exceed 1.0, and for cost considerations, demand or with high impact resistance. Proper material selection and technique can be very important.

Infrared is invisible electromagnetic radiation transmitted by the sun. Since ultraviolet, visible, and infrared electromagnetic waves with a wavelength of 280 to 100 nm cause interference with various electromagnetic waves, especially infrared rays between 800 and 1200 nm, it is important to implement the best way to protect human eyes. Since infrared absorbing lenses are not easy to obtain, there is not much information about them. In addition, research is difficult and infrared absorbing dye materials are expensive. There are some products on the market, but they do not function well. Considering that the potential sunlight or artificial light sources mentioned above can effectively block harmful light waves, this application can enact many improvements to sunglass lenses, optical solar prescription lenses and optical sheets.

Embodiments for spectacle lenses, goggle lenses, shields or sheets

Embodiments are provided for spectacle lenses, goggle lenses, shields or sheets. Embodiments may include organic dye (visible narrow band absorber) films that are selectively subjected to narrow bandwidth wavelength attenuation (absorption) of unwanted radiation light, particularly with respect to low haze, sharpness, or/or colorful contrast enhancement. .

It also adds an organic absorbing IR dye protection layer that reduces eye strain, increases visual comfort and enhances the clarity of scenes in high-resolution color.

The lens contains a casting function film or a plurality of casting function films and laminated films in a convex or (that is, with or without grinding, 0.0-1.5mm depth on the lens surface without damaging the function film, and the total thickness of the lens is 0.2 to 10.0 For IR thin films, add 0.02~0.18mm to the convex or with or without polishing the film, insert 0.0~1,5mm deep into the surface without damaging the functional film, the total thickness of the lens is 0.2~10.0mm The application is a manufacturing method.

Dyes with full width at half maximum (FWHM) in the range of 10–80 nm are generally not amenable to dissolution in organic solvents. One of the only solvents that can be dissolved is less than 0.1%-0.2% of the mixture, coating with the recommended common solvent. The thickness is about 0.05-0.08mm. If the dye content is too low, the desired effect may not be achieved. If a solvent that is too strong is used, the coating mixture and the coated substrate will be damaged by the strong solvent. However, for solution cast films it may be desirable to use some of the strong solvent soluble dyes and polymers. When making a film by choosing solution casting, the film can be 5 to 30 times thicker, so the dye content can also be increased by 5 to 30 times, and strong solvents can also increase the solubility by 3 to 15 times depending on the dye.

The 400-455nm region is more than 8% lower than the 480-550nm region. Special demand 440-490nm is less than 5% in the 400-440nm region. Contrast enhancement can be achieved by selecting suitable dyes at 570-595 nm.

Near infrared organic dyes are selected at 700-1200nm, and 1200-2000nm organic IR dyes are waiting to be added to the lens.

Critical Application Elements

1. FWHM - One lens contains at least one FWHM, a soluble functional dye with an absorbance of 10-50 nm (visible narrow band absorber) with a polymer. Haze should be less than 1.0.

2. The solution cast function film lens includes a solution cast function film or a plurality of solution cast function films and a convex or laminated film (ie, over the lens).

3. Polishing or polishing without damaging the functional film without polishing, but forming a convex or (i.e., 0.0-1.5 mm deep) functional layer on the lens surface to a depth of 0.0 to 1.5 mm on the lens surface without damaging the functional film, so that the entire lens thickness is between 0.2 and 10.0 mm.

4. High Contrast or Enhanced Contrast, applications (C) increase the contrast by focusing radiation wavelengths absorbed between 570-590 nm so that the human eye can better distinguish objects and extend the clarity of scenes with high-resolution color .

5 laminate absorbing IR radiation thin film. Benefits may include ease of operation, ease of application, easy storage of functional films with a low variety of films, easy preparation of raw materials, reduced layering, and reduced risk of separation. Another benefit is increased yield. Another advantage is one layer process cost reduction and superior quality.

The functional film is concentrated in the top half of the outer contour. function is concentrated. The Semi Rx lenses' functional color mode greatly reduces clipping, features are more average, and colors are relatively flat.

Solution cast film, injection molding, gasket casting and lamination are various processes that can be selected alone or combined. The function can be to protect the layer barrier, and the same, similar or different functional layers can be superimposed and, if necessary, to achieve absorption, transmittance greater than 0.001%, greater than 0.0001%, transmittance of 0.00001%.

-Functional dyes can be mixed together or separately in one film and the film material can be different.

- one or more solution cast films are laminated, co-injected or co-cast to a lens, shield or sheet.

-or any combination of lens components.

- Attenuates the selective wavelength region. These (AB)UV dyes-VIS dyes can be used alone or in combination to create custom spectral filters for many applications. UV dyes also combine most easily with most dye mixtures used.

- (B) Filter the highest energy wavelength of 420-455nm. 400-420nm (A) 420-455nm becomes very important if UV 400 dye absorbs some of it, but it's easy to absorb dyes in this region and interfere with other color regions, so use the correct solution casting method or some layers will have a narrow bandwidth (FWHM) ), you need to inject, cast, and use the right dye, just like you would use a 40 nm dye. Mix with one or more other functional dyes.

(C) - This application is to solve the problem of deteriorating eyesight when wearing protective eyeglass lenses due to the maximum emission of the sun of about 580 nm. The present application (C) helps the human eye to better distinguish objects by increasing contrast by focusing radiation wavelengths absorbed between 570-590 nm. Spectacle lenses with high or medium contrast enhancement provide better transmission in the red and green visible spectral ranges.

- (B) General (broad range) colored dyes for 400-760nm can be selected for use as they absorb visible dyes. Some adjustments may be needed to sharpen the colors and darken the lenses. Blue light-blocking lenses, or new high-, medium-, or low-contrast methods added to blue-blocking lenses, allow people to see clearly, easily, in detail, fast and far. Visible light may be filtered by attenuating a portion of the light transmitted by the lens within one or more of the filtered portions of the visible light. The optical filter may include means configured to increase the average saturation value of a narrow notch of 40 nm +-30 nm bandwidth having a uniform intensity with light emission that is at least partially transmitted through a portion of the lens.

- Combined with other dyes, it selectively transmits predetermined primary color wavelengths.

- Proper mixing of two or more dyes may be required to absorb 400-470 nm.

-New lens with multifunctional performance, indoors, bright colors in the rain or early morning, dark colors in sunny days and outdoors.

(D) Near-infrared absorption function.

Organic IR dyes absorb near-infrared light from 760 to 1100 nm. This function is more efficient than inorganic IR dyes. Inorganic IR dyes are haze-containing and granular, so they cannot be used in too high a proportion, as they can reduce brightness.

The newly developed IR absorbing dye has higher transparency in the visible light region than existing products.

Current state of the art organic IR dyes are well suited for the near-infrared 700-1400nm, but above 1400nm they must be mixed with inorganic IR dyes.

The hot glass lenses melt together with the infrared dye. For the absorbance of 760-1400nm, only the peaks of the 750nm, 810nm and 890nm parts of the radiation can be absorbed, and the quality of 760-1400nm organic NIR dye clarity, high performance absorption, clarity, comfort, and HAZE was in the middle range.

Absorbing between 400 and 470 nm may require a proper mix of two or more dyes. The correct method of solution casting, injection or casting and the use of narrow bandwidth (FWHM) 40 nm dyes must be used to ensure the correct dyes are used. Mix with one or more dyes.

The lens in (D) absorbed more than 38% in the 760-1100nm portion, and the same lens absorbed more than 20% in the 1100-2000nm portion.

6. Different dyes can be combined in the same film.

7. Functional films using co-injection substrates.

8. The above can be added with our (A) UV powder dye or configured with or without polarized light.

Polymer materials; and at least two filters integrated into the polymeric material of the lens, wherein the two filters are combined to form a sharp cut-on filter that blocks most (A) ultraviolet light and substantially blocks wavelengths shorter than 400 nm-455 nm, followed by blue and violet light. It consists of a lens that selectively filters the (film)

Here, the plurality of organic dyes include a blue absorbing organic dye, the blue absorption peak center wavelength is from 400nm to 455nm AB, and the highest energy wavelength (B) 420-455nm is filtered. 420-455nm where 400-420 UV 400 dye absorbs some is very important, but it is easy to absorb dyes in this region and interfere with other color gamuts, so the correct method of solution casting, injection or casting and narrow bandwidth (FWHM) 40nm dye to use the correct dye.

In some embodiments, various options, methods, processes, etc. may be used (eg, using film or injection molding or other suitable processes) to create a suitable glass having desired light transmission properties. A combination of injection molding and/or solution casting may be used for glass (eg, eyeglasses). In one embodiment, a combination of dyes that absorb or block light in the visible range may be used. Dyes that absorb or block light in the infrared range can also be used. Other dyes with properties in various wavelength bands of the entire light spectrum may also be used according to user preference and design. Various combinations of films and/or injection molding materials can provide advantages to manufacturers and end users. A few examples include speed, efficiency, configurability of the manufacturing process and the end result.

In one example, dyes associated with prominent solar ranges such as the blue light range (about 400 nm), the solar peak at about 580 nm, and the infrared range (e.g., ground surface) can be incorporated for beneficial use into the glass film. It will be appreciated by those skilled in the art that any combination of dyes relating to the various light spectral ranges may be used.

Some combination examples are shown in Table 2 below. The types of dyes are listed in the first row. EMI, EM2, EM3, EM4, EM5, EM6, and EM7 are exemplary examples that include the process types available for each dye. For example, Example 1 (EMI) may include a 400 nm dye and a 580 nm dye injection molded onto a substrate and an IR dye deposited onto (eg, laminated to) a film. Films can be bonded to substrates containing 400nm and 580nm dyes. In another embodiment, each dye may be deposited on each individual substrate while the substrates are later bonded. In another embodiment, each dye may be deposited via casting onto its own film substrate. In this way, one or more dyes can be included on a substrate to which one or more substrates are bonded, and similarly, one or more dyes can be included on any combination of one or more films. The film, casting and substrate may be combined in any operational sequence.

EM2-EM4 represent other exemplary combinations of injection molding and film combinations. The examples in Table 2 are illustrative only, and one skilled in the art will recognize that any combination of dyes can be used in any combination of depositing dyes onto a substrate (film, glass, etc.). One skilled in the art will recognize that any number of layers and any number of dyes may be used.

7A-Z show examples of spectroscopic charts using various example dye combinations. The result may be produced by the solution casting method, but other methods may be used. Unless otherwise specified, "%T" or the Y-axis indicating light transmittance may be used in the chart, and the X-axis may indicate light wavelength in nanometer units.

7A shows the spectrometer output 700a when using a blue dye with near-infrared absorbance properties (blue blocker) in combination with a contrast enhancing dye. The spectrograph output shows little or no transmittance in the ultraviolet range, with a peak in the visible spectrum and a trough in the near infrared range.

7B shows another spectroscopic output 700b for a film using a blue dye (blue blocker) with a contrast enhancing dye. The spectrometer output has little or no transmittance in the blue light range of about 400 to 430 nm, and shows a trough band around 580 nm (about plus/minus 15 nm). Another example that can provide similar results is the addition of a co-injected or gasket-cast substrate mixture that contains an organic dye that absorbs near-infrared radiation or a blue-blocking dye and a contrast-enhancing dye.

7C shows another spectroscopic output 700c when using two or more functional dyes effective in the 420-700 nm range. It can be seen that the spectrometer output shows a sharp rise around 400nm and then slightly lowers around 570nm.

7D shows another spectroscopic output 700d of a liquid coating technique with inorganic dyes. The spectroscopic output shows that the dye absorbs less near-infrared radiation and can produce higher levels of haze.

Figures 7E-F show different spectrograph outputs 700E-F when using temperatures as high as 800 degrees or more to melt the dye mixture. The results show that using higher temperatures does not result in absorbing more NIR radiation in the 760-1400 nm range.

Figure 7G shows another spectrometer outputting 700 g when making a film containing a blue blocker effective at 400-43 Onm with a contrast enhancing dye effective in the 580 nm range (+/- 15 nm).

Figure 7H shows another spectrometer output 700h when a lens is made by injection molding using two or more functional narrowband dyes and an organic near-infrared material. The output shows a higher transmittance around 700nm where there is attenuation at the edge.

7I shows another spectrograph output 700i produced using a combination of solution casting (on film) and plastic injection molding. In this example, the film contains 0.5% of an organic near-infrared dye, and the plastic contains 0.05% of a blue blocking dye effective in the 400-455nm range and 0.03% of a contrast enhancing dye effective in the 570nm range (+/- 15nm). As a result, it shows an advantageous output that blocks high levels of light (or low transmittance) in the range of about 400 nm, 570 nm and near infrared.

Figure 7J shows another spectroscopic output generated using organic NIR dye at various concentrations: 0.15% ("1"), 0.20% ("2"), 0.42% ("3") and 0.60% ("4"). represents 700j. The chart shows the lowest concentration (“1”) as the upper curve with the highest (or lowest) transmittance across wavelengths, and the chart shows the next lowest concentration. ("2") is the second highest curve with high transmittance (or low absorption) across wavelengths, and the chart indicates the next lowest concentration. ("3") is the second lowest curve with the second lowest transmittance across wavelengths, and the chart shows the highest concentration. ("4") denotes the curve with the lowest (or highest) transmittance across the wavelength.

7K-L shows another spectroscopic output 700K-L generated by comparing the difference between using a non-vacuum coating process and a vacuum coating process. The results show that the vacuum coating process increases the absorption of near-infrared radiation compared to the non-vacuum coating process.
