Description

A kind of comfortable type anti-blue light tinted lens

Technical field

This utility model relates to a kind of comfortable type anti-blue light tinted lens.

Background technology

The light that people's vision can be experienced is referred to as visible ray, and it is a kind of wavelength electromagnetic wave between 380-780nm scope, the color such as including " red, orange, yellow, green, blue, indigo, the purple " known to us.Visible ray can be divided into shortwave light and long wave visible ray, and wherein the wavelength region of purple light is 380-430nm, and the wavelength of blue light is 430-470nm, and the crest of ethereal blue light is at 470nm.The wavelength of purple light is shortwave in visible region, and its frequency is the highest, and blue light takes second place, therefore the light that wavelength is called 380-470nm region is shortwave light.So, the visible ray at 470-780nm just claims long wave visible ray or claims effective visible ray.

Research according to Die Monocrom-Lichtdome, A. Wunsch, Sensora Light Modulation and R.H.W. Funk professor, our eyes are when " inappropriate light " prolonged exposure, the functional disorder of health can be caused, the light that especially LED, computer screen etc. send, the inside high energy shortwave blue light containing a large amount of irregular frequency, these shortwave blue lights have very high energies, it is possible to penetrate crystalline lens and go directly retina.Blue light illumination retina can produce free radical, and these free radicals can cause retinal pigment epithelium to become feeble and die, and the decline of epithelial cell can cause photosensitive cell to lack nutrient thus cause vision impairment.FUNK more points out, these " unsuitable light " are the most old arch-criminals losing blind-maculopathy (AMD).

And according to international ISO definition, blue wave band is: the high-energy visible ray of 380nm-500nm.Blue light is the important component part of visible ray, and nature itself does not has single white light, blue light to present white light after mixing with green glow, gold-tinted.Green glow is less with gold-tinted energy, less to eye irritation, and blue light ripple is short, possesses high-energy, it is possible to the crystal being directed through eyes goes directly on eye ground.Numerous scientific experimentss are also had to prove: retinal pigment epithelium becomes feeble and die at most under the blue light of 415-455nm wavelength, shows the blue light the most most nocuity of this section of wavelength, can cause the impaired visions such as degeneration of macula, and 465-495nm is then useful blue light.

" bad light " refers to " unsuitable light ", " harmful light ", long-term irradiation including ultraviolet (UV) and high-octane visible ray (HEV) (shortwave blue light) etc. will cause some ocular disease, as: the generation of age-related macular degeneration and development (AMD) retinal degenerative diseases, the most also there is no cure method.

" good light " is also " useful light ", show according to the study, if the health of people is exposed under " good light " (such as: long wave blue light) of a specific scope for a long time, help lend some impetus to the physiological equilibrium of health, contribute to creating a positive good mood, away from sad mood.Research also shows: long wave blue light can be absorbed by the sclererythrin of Propiobacterium, destroys antibacterial and reaches to treat the effect of skin sore, and blue light also has and staticizes the health skin and to antianaphylactic ability of releiving simultaneously.

Currently,The most common blue-light resistant lens can only filters ultra violet line and electromagnetic radiation, it is impossible to effectively filters out blue light, does not more have selectivity lucifuge, while keeping away ultraviolet, has also kept away the visible ray of all wavelengths.Usual this sunglasses chromatic discrimination power is relatively low, and vision definition is poor, and current eyeglass is attractive in appearance, and function and definition, again by interested in consumers in general, become the primary selection selecting eyeglass.

Utility model content

The purpose of this utility model is to provide a kind of comfortable type anti-blue light tinted lens, can filter blue light selectively, make eyeglass filter or absorb blue light effect to reach optimal.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of comfortable type anti-blue light tinted lens, uses PC(Merlon) or TR(polyamide) make lens substrate, form dye layer on the two sides of base material respectively, then form strengthening layer respectively on the surface of two dye layers.

The light transmittance of described eyeglass is 13%-18%.

After using said structure, this utility model utilizes dye layer and strengthening layer, selectively filter blue light, makes eyeglass filter or absorb blue light effect to reach optimal.On the one hand; " bad light " (such as: ultraviolet and shortwave blue light) can be intercepted to greatest extent; obtain optimal filtration rate and optimal light transmittance; reduce its injury to human eye, thus protect eyeball, allow the eyes of people feel relief nature; impayable visual experience is provided; contribute to that you see is more clear, farther, more comfortable；On the other hand, " good light " (long wave blue light) in allowing available light or novel artificial light source converge to greatest extent passes through simultaneously, and still keeps fine definition, people is allowed to keep body and mind joyful, to the positive impact that health one is lasting, allow people see happiness, feel happy.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Shown in Figure 1, this utility model discloses a kind of comfortable type anti-blue light tinted lens, use PC(Merlon) or TR(polyamide) make lens substrate 1, dye layer 2 is formed respectively on the two sides of base material 1, dyeing temperature is 90 DEG C, time is 250s, then forms strengthening layer 3 respectively on the surface of two dye layers 2.

The light transmittance of this utility model eyeglass is 13%-18%.The wave amplitude figure of this utility model eyeglass is not like the parabola wave amplitude of common sunglasses on the market, and it has oneself specific amplitude curve amount.Owing to the wavelength of blue light is 430-470nm, the crest of ethereal blue light is at 470nm, and therefore the amplitude curve of this utility model eyeglass reaches the highest at 475nm exactly, and 550nm reaches minimum, the most gradually rises in 700nm, is wave amplitude peak to 780nm.

This utility model has uv-resistant function, it is possible not only to 100% stop UVA effectively, UVB, UVC and the harmful radiation of long wave blue light, " bad light " ray (ultraviolet and shortwave blue light) can being substantially prevented from light, can effectively utilize long wave blue light simultaneously, according to nearest ophthalmology experiment display, absorb the radiation of part long wave blue light, more " good light " ray (long wave blue light) can be effectively allowed to pass through, create lively, clearly, comfortable, non-general visual experience, be conducive to helping people away from emotional problems such as depressions, bring happy and happy for wearing the guest of these glasses, eyeglass color and luster high-fidelity, depending on thing distance high-resolution, can also effectively shield electromagnetic radiation and ultraviolet, possesses the anti-pressure ability of excellence, anti-scratch ability and the performance such as high temperature resistant.
