Description

[Detailed description of the invention] Polarized lenses for sunglasses and their manufacturing method Technical field The present invention provides novel polarized prescription sunglasses, prescription Processing method for polarizing film adhered to glass lenses and products made using the same method Regarding.

52 Fu Street The theoretical potential of polarizing filters has been known for a long time, but there are no practical polarizing materials. Examples include Alvin and Mortimer Marks. Iodine crystals developed in the 1930s by Marks) created a useful polarizing material. It's the first. William Bird Herapas Rapath) discovered polarizing materials in the mid-1860s, and Philoso, London. Ph1losophical Papers (London Ph1losophical Pape rs). H. Amron (H. Amron) was born in 1919. 6 Accidental double refraction in cellulose celluloid J (Accidental Double Refraction in Ce1luroid in 6 Ce1Iulose) Conroy, J., reported iodine polarized microcrystals in 1876. 1 Even before 930, many researchers had discovered dye-directed fibers and the dichroic effect. ic effect).

In the 1930s, Alvin and Mortimer Marks created directional plasti. We have developed a method for growing crystals attached to surfaces such as glass and glass, and have developed continuous crystal polarizers. It was created. This new material allows for the first time to reduce natural glare and reflections. It has become possible to evaluate the polarization rate of polarization phenomena. A few years later Nidwin Run, Do (Edwin Land) assembles microcrystals that have been given directionality by stretching. Quinine sulfate iodide in Herapas for the first time as part of an embedded plastic structure Contributing to the technology using salt (iodo quinine 5 ulphate) did. This relatively inexpensive new polarizing material can be quickly used in sunglasses, photography, and scientific instruments. It was used for a variety of purposes, including vessels and military equipment.

Of all the potential applications for this novel polarizing material, perhaps the most promising one is eyeglasses. Will. American polarization (non-prescription) sang The market in Las is vast. The first polarized eyeglass glasses released were flat. It was laminated glass and was polished to a predetermined degree. These glasses are high It is expensive and heavy to hang due to the thickness required. Polarized lenses, especially Despite the fact that early versions are relatively expensive compared to non-polarized tinted lenses , there is a small but significant market. However, most of the market is Polarized eyeglass glasses can be used.

The various alternative methods have various drawbacks. Clip-on type polarizer has two additional surfaces that collect dust and other materials that impair visibility. clip-on style Polarizers are necessarily light in construction and are susceptible to damage, wind-blown and other forms of There is instability.

For this reason, clip-on polarizers have traditionally been more polarized compared to non-tinted eyeglass glasses. Prescription glasses will never have the same market share as non-prescription glasses. I didn't.

Rather, light-attenuating prescription sunglasses are often made with tinted, non-polarized glass. It was Tinted non-polarized glasses can be used with finished eyeglass lenses (fitted to the desired power). Contains lenses that are polished to match the glasses frame) The finished product is then coated with filter material. The filter material has polarizing properties. Until now, the performance was inferior to that of polarized glass, but with this manufacturing method, This has the advantage of allowing attenuated light to enter the wearer's eyes easily and reliably.

However, if a polarizing film is placed on one side of a small piece of glass or plastic, With a degree of polarization made by gluing and covering another glass on top of the polarizing film There are few sunglasses available in the light attenuating glasses market. this sandwich The spectacle glass structure has a polarizing material layer between two glass layers. This glasses glass , made by injection molding lens plastic around a polarizing filter. Can also be done.

The edges of the lenses must be trimmed to fit into the frames of the glasses. this Processing can only be carried out after the polarizing layer has been placed between the two stacks. This processing takes place in a typical eyewear retailer's workshop. The retailer's workshop has a predetermined degree. He buys polarized lenses and processes them to fit the special frame shape.

Polarized prescription lenses are fragile, so the polarizing layer and transparent sandwich members are easily damaged.

Prescription polarized lenses are expensive and easily scratched, so polarized sandwich lenses It is difficult to use lenses for polarized sunglasses. However, polarizing materials have been developed Almost 50 years later, no other commercially viable solution has yet been presented.

The skin Ω plate ヱ The present invention seeks to solve the difficulties of the prior art as set forth in the claims. That is. The present invention provides an inexpensive and effective polarized prescription lens. This is what I am trying to do.

The method and system of the present invention are different from the prior art in which lenses may be damaged. The aim is to solve the various problems with the system and its manufacturing method. Furthermore, the final The product has the advantage of not allowing UV rays to enter the wearer's eyes and is very inexpensive. We are prepared. Furthermore, the system of the present invention can be used for glass, CR39, polycarbonate It can also be applied to fully integrated glass made from , it can even be applied to used glass. CR-39 has extremely high internal stress. CR-39 glass is the preferred substrate because of its small size. In this way, consumers compare Now available at a relatively low price compared to purchasing expensive special polarized eyeglass glasses. You can convert your old eyeglass glasses into prescription sunglasses. i.e. , according to the invention, the price corresponds to a small fraction of the current price of spectacle glasses with degree of polarization. This shows that it is possible to create a product with almost the same functionality.

The above method uses a drop of liquid to expel the air between the laminate and the lens, creating polarized light. This is accomplished by applying a film to a curved surface.

In relation to this, polarizing film has a material structure on the micron level, so it is difficult to remove it. Special handling issues arise and, as with most prescription lenses, orthogonal Special problems arise when bonding to curved surfaces, and the present invention is based on the technical expertise of the method of the invention. The following presents a special problem addressed by the sequel. Specifically, adhesive to glass substrate Attach the stretched film to the frame before aging. , the uniformity of the product is improved by softening. Polarizing film on curved surface Adhesive lamination methods are known, but various problems hinder the practical application of this lamination method. . See U.S. Pat. No. 2,354,692; No. 3,300,436.

Best form for implementing annotations As mentioned earlier, in order to make eyeglass glasses with a degree of polarization, the conventional method was to Polarizing film (sandwich structure so that it can be polished to prevent damage) I had to get polarized lenses that already had lenses embedded in them. polarizing element The material is usually very expensive compared to glass or plastic. Therefore damage or polishing Errors are costly, and the industry practice is to include them in the price of the glasses. .

Such polishing errors and defective materials are a must for those who want glasses at a reasonable price. We cannot afford to ignore and bear the cost of this.

The object achieved by the present invention is to prevent the high costs caused by damaged polarized lenses. In addition, it is possible to reduce the cost of polarizing optical materials and reduce defects and polishing errors. That is.

In accordance with the present invention, disclosed in Albin and Mortimer U.S. Pat. No. 3,300.436 Make casting material according to the technique described. As a casting material, Although polyvinyl alcohol is commonly used in the prior art, the present invention It is desirable to use casting materials based on polyvinyl butyral.

This casting material was applied to a peristaltic pump with a silicone tube (peristaltic pump). Pall Trinity (c pump) l Pass through a 0 micron filter. The silicone tube has a catalog number of MasterFle. x Code Nan/<-6411-18 (Masterflex Code Walter Cooling Company listed in Na6411-18) Walter Cooling Co, (Rose Dale, New York). The filter is new - Chassis (New Jersey) Ball Trincore - (Pail T Made by Rincor.

Referring to FIG. 1, 40 g of liquid 8 passed through a filter is placed in an airtight chamber Spin at 00 rpm for 10 seconds (or remove any iodine present in the mixture). If the amount of raw material is more than the appropriate amount, add 3 seconds to the time). Spinning is a circular plastic This is done on a 10' x 10' glass plate 12 placed on top of a tray 14.

The spinning time can be determined by comparing the color of the mixture (liquid) with the reference color as shown in Figure 1. Controlled within the device shown in . Specifically, it is directly based on the light emitted from the light source 26. Photocell (through filter 5 standard) 2B photocell) 30 and spin the output of the photocell 30. The output of the photocell 32 that receives the light that has passed through the liquid 8 is compared. Reach desired color density If so, a comparison is made by the control circuit 34 which stops spinning. Minimize turbulence and swirl Use an airtight chamber to reduce If the diameter is small, the diagonal length of the plate 12 is A circular platen 14 of equal diameter is used to further reduce turbulence as well as vortices. vinegar A topper 36 holds the plate 12 in place on the platen 14.

Next, the spun film was covered with a glass plate at 1/4' upwards. , reduce evaporation, allow air bubbles to rise, and smooth the film through natural surface tension. Ru.

Dry for 30 minutes in an airtight dustproof container. Then the color of the film changes from yellow to dark blue. Air dry until solid.

Next, cut the film down to 1/2' from both edges and turn it in one direction to restore the original film. Stretch it out to 5 to 6 times its size and cut it in half perpendicular to the direction it was stretched. Continued Cut each of these film halves again along the center line in the direction in which they were stretched. , and a piece of l/4 film taken from one half-sheet, which corresponds to a pair of eyeglass glasses. (Fig. 2). 1 large center hole in each board 100 102 and two fixing holes 104 are provided. Keeps the film stretched To do this, double-sided tape is placed along the outer periphery of the film and plastic plate. Or glue is used. The film is stored at room temperature (20-22°C) and relative humidity. Stretch by 55% or less.

Next, the stretched film was placed on a board 100 for 4 to 10 days for two days of sheathing. Dissipates urin. This will ensure uniformity of color (Co) upon immediate use of the film. lor regularity (low temperature baking) This allows the aging time to be shortened.

According to the present invention, the glass, CR-39, poly The surface of the finished lens, such as one made of carbonate, is treated, and the surface of the lens and the The unique bonding method between the butyralium lithium-iodine polysilicate complex formed Therefore, a polarizing film can be attached.

The composition of the surface treatment liquid is as follows; sulfuric acid (98.08%) 500 weight Chromium trioxide 1 part by weight Place this treatment solution on a concave glass whose curvature is close to that of the CR-39 lens to be treated. Ku. Next, place the CR-39 lens on top of the acid and turn the concave glass surface into a convex lens surface. for 20 seconds to distribute the acid over the entire surface to be treated. Next is the lens Wash with water and dry. When working with this acid mixture, do so in a well-ventilated area. and use a rubber apron, gloves, and eye protection.

Surface treatment can alternatively be performed in a plasma generator for up to 1 minute. child It is also possible to combine these two types of processing methods.

Next, measure the curvature of the lens with a lens gauge. Subsequently processed lens 110 is fixed in place on the device 200 shown in FIG. 3 with adhesive 202, and the lens is Make sure that the axis of the film and the polarization direction of the film are coaxial, and then remove the coating. When incorporating the filtered lenses into the completed pair of sunglasses, the polarizing film 108 is Maximize glare filtration.

Placed on base plate 100, e.g. adhesive applied around hole 102 Or, turn the film fixed to the base plate 100 with double-sided adhesive tape upside down, Film 08 will then form a container with the bottom, made with the following composition. Treat the back side of the film with a softening solution: Fukika deer Distilled water 100 parts diacetic alcohol 1 part Normal Propatul 4 parts (glacial) acetic acid 17 parts Hydrochloric acid (37%) 1 part (1% distilled aqueous solution) Total 122 parts At side 111 of hole 1O2 Pour the softening liquid into the small chamber that has been formed and wet the back side of the film. Softening liquid remains The softening liquid should only be applied to the back side of the film 110, as this will affect subsequent processes. is important. This is done for 75 seconds. Next, drain the softening liquid and empty it on the surface. Blow away the remaining machining liquid droplets.

Next, the base plate lOO to which the film 108 is attached is placed on the device 200, From the etched front side of the lens to which the coating should be applied to the back side of the film. Position about 1/4 inch. Hole 206, gauge 208 and vacuum pipe A light vacuum is created in the chamber 204 through the pipe 21O, and the film is drawn as shown in phantom lines. Achieve the necessary curvature to bring the lens into close contact with the lens surface. Next, add several d of distilled water. or other liquid). In the case of a flat surface, a vacuum is not necessary.

Apparatus 200 includes a vacuum section 212 and a mounting section 214. The vacuum portion 212 is a vacuum Vacuum circuit consisting of pipe 206, gauge 208 and vacuum pipe 210 and is connected to a vacuum source with adjustable pressure. Upper end flexible membrane body of gauge 208 216 moves downward in response to the vacuum. Accordingly, the driven body (folo).

er) 213 moves downward against the spring 220. One of the springs 220 The ends are fixed to a follower 218 and a fixed point 222. Next, the driven body 218 The indicator 224 is pivotally connected to a point 226, and the indicator 224 is pivotally connected to a point 226. The power of the lens is dioptre depending on the pressure used to curve the lens. pter) is indicated on the scale 228, and the film 108 is adjusted in response to the application of pressure. The curvature is corresponded/indicated by a scale 228. That is, the polarizing film layer should be applied. In order to almost completely match the curvature of the lens surface, the deformed film 1 shown in FIG. Use this device to adjust the vacuum pressure to the point where the 08 shape is formed. is possible.

The structure of the support portion 214 is such that a pair of threaded members 230 are connected to a nut 232. It is fixed to the plate 100 by a locking nut 234. located on the opposite side The support body 238 and the spring 240 are pressed against the nut 241 by the nut 236 , the support 238 is adjustably mounted. The tube 240 of the support 238 is a rotary knob. The spring 242 is advanced by the rotation of a threaded member 244 fixed to the spring 246. and is pushed toward the support body 238.

The square ram 248 advances accordingly, and the outer shape of the square ram 248 is the same as that of the square tube 24. 0, and the ram 248 to which the lens 110 is attached is the film advances toward the film 108 without rotating. In this regard, fi In order to deform the chamber 108 into the shape shown by the imaginary line in FIG. The chambers 212 are sealed together to maintain a low pressure within the chambers 212. Let me state this. In general, the shape of the film is The convexity of the glass surface must be only slightly smaller than the convexity of the glass surface. Do that For example, the center point of the convex surface to be coated should first contact the film. Can be done. As the ram advances, other parts of the film stretch and come into contact. This growth must be kept to a minimum. In this way, the difference in concavity can be minimized. Can be done easily.

On the other hand, if the film is more concave, liquid will accumulate and damage the polarizing coating. be called.

To achieve lamination, tighten the knob 246 and remove the film with distilled water 250 at 1- 108 and the lens to be coated. Polarizing fiber instead of water 250 Use other liquids that do not chemically interact or adversely affect the lume. It is also possible to use adhesives or other materials.

Then tighten it a little more than necessary to make contact with the film 108 to ensure good adhesion. keep The coating formed is then examined by looking through another polarizing filter. Check product quality.

Next, wait 45 minutes and then chuck the lens with the film attached together with the ram assembly. Take it out from the chamber 204, put it in an air opener with the surface facing up, and keep it at 77℃ for 115 minutes. Bake for a while. Once baking is complete, use a sharp razor to remove the film from the edge of the lens. Cut to match.

Remove the lenses from the ram and bake them face up for 2 hours at 68°C. and air dry overnight (approximately 12 hours).

Apply the first silicate solution (5 oluhon) to the lens for 15 minutes. Apply for seconds to lock into the iodine. Then briefly spin the lens. Blow dry with air and place under a heat lamp for 5 minutes.

The first silicate treatment step is carried out curing at a relative humidity of 60% or less. Ru. If the relative humidity is above 60%, the lens will become cloudy, and the silicate treatment will cause the lens to become cloudy. Not effectively stable. The composition of the silicate liquid is as follows: Butyl alcohol 20 parts Tetraethyl orthosilicate 8 Part 0 of tetraethyl orthosilicate is manufactured by Union Carbide, Coating Chemistry Department ( Danbury, Connecticut) (Llinion Carbide.

Coating Chemicals Division (Danbury, Connect). Then in a second silicate treatment step A surface-sealing gefate resin solution is applied to the lens, and the lens is briefly spun. Shake off excess resin liquid. The lens was then air-dried under a heat lamp for 5 minutes. Then put it in the oven and bake at 77℃ for 2 hours. Once baking is complete, Cool the noodles to room temperature.

To make the silicate resin liquid in the second step, first, make a base with the following composition. Make the base: Butyl acetate 22.0 parts by weight acetic acid 7.0 parts by weight Toluene 17.0 parts by weight Methyl isobutyl ketone 48.0 parts by weight Butyl lactate 25. 0 parts by weight Normal Propatzl 20.0 parts by weight XYSG 6.6 parts by weight Total 145.6 parts by weight Then this base Pass the sample through a 10 micron Pail filter. The following is the base for part 14. Add: Silbond (pure ethyl silicate) 3-part butyl acetate 5 parts toluene 5 parts silbond (5ilb ond) is Stouffer Chemical Corporation.

Next is Owens Illinois hard court (Owens l11inoi s　Hard　Coat) on the lens. Additional tactile agents to prevent iodine dissipation Modify the hard coat by adding media. The amount of catalyst in the hard coat is 2%. 3%. The lenses are then baked for 4 hours at approximately 82°C. commercially available purple It goes without saying that it is also possible to use an external radiation curable hard coat.

As shown in FIG. 4, by making the amount of stretching of the polarizing film 310 the same, Twin lenses (matched 1ens) can be made. Here, edge 31 1 and 312 and pull them in the directions of arrows 313 and 314, respectively, to release the film. stretch. Stretching helps to achieve uniformity in the direction perpendicular to the stretching direction.

Cutting along line 316 in this manner creates a pair of generally twin film members 318 and Make 320. If you wish, you can omit the cutting and use the two-person base shown by the imaginary line. It is also possible to use a base plate 300.

It is also possible to make special lenses according to the invention. - For example, segmentation Bifocals with segment lenses ts protruding) is biased by liquids such as softening fluid that accumulate during processing. The optical film becomes disorient. How to solve this problem The method is to apply a polarizing film to the entire lens, and then remove the film from the bottom of the lens. rip off the mu. This is because the shape of the lens causes the problem. Kay Acid treatment and/or baking may cause the film to stick to the CR-39 lens. The film can be easily removed by cutting the film and pulling it apart before can. Other process parts are the same. Alternatively, the film 412 shown in FIG. Smooth lens (smooth 1ens) 4], 0 is a bifocal member 4 14, and a bifocal progressive unidirectional translucent (progressive single) evision) It is also possible to make wafer lenses.

In addition, the surface of the material is treated with a plasma generator or NaOH or KOH, It is also conceivable to etch the surface sufficiently to allow the polarizing film to adhere.

Similarly, the invention is not limited to spinning polarizing films on glass. 3. The purpose of spinning technology is to ensure uniformity and improve surface finish. That is. glass wheel machine ) can also be used.

In addition, barrier coating: photoresist coating on top of silicate resin liquid. is applied and insolubilized by irradiation with strong ultraviolet rays, and other hard coats act on the polarizing agent. It is also possible to prevent this. Then a catalyst such as benzoyl peroxide It no longer penetrates the barrier, and is formed by coating the surface with a monomer such as CR-39 and forming a bond. can be touched.
