Description

A kind of anti-blue light color-changing lens

Technical field

This utility model belongs to optometric technology field, relates to a kind of anti-blue light color-changing lens.

Background technology

Along with development and the progress of science and technology of society, electronic product is in we live Application more and more extensive.Such as, the use of the electronic product such as mobile phone, TV, computer Go deep in our daily life.Wherein, the electronics such as mobile phone, TV, computer produces Product are respectively provided with display screen, and these display screens can produce the high energy shortwave of a large amount of irregular frequency Blue light, these blue light illuminations can make retina produce free radical, and this can cause retinal color Element epithelial cell decline, thus causes photosensitive cell to lack nutrient, can allow eyes dry, Turn sour and astringent, and then cause visual deterioration, absent minded.Meanwhile, in outdoor Time, eyes also can be caused damage by blue light and ultraviolet in sunlight.

Summary of the invention

The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that A kind of anti-blue light color-changing lens, this utility model solves the technical problem that it is how to protect eye Eyeball is from blue light and the infringement of ultraviolet.

The purpose of this utility model can be realized by following technical proposal: a kind of anti-blue light Color-changing lens, including substrate, it is characterised in that the outside of described substrate has color-changing membrane Layer, the outside of described color-changing membrane layer has transmittance film layer and antireflection film layer, institute successively State transmittance film layer and include chromic oxide layer, tantalum pentoxide layer and five oxidation three titanium layers, Described antireflection film layer includes titanium dioxide zirconium layer, radiation prevention film layer and silicon dioxide layer, institute The outside stating antireflection film layer has protecting film layer.

This anti-blue light color-changing lens passes through color-changing membrane layer, transmittance film layer, antireflection film layer Superposition mating reaction with protecting film layer so that this eyeglass can either play the work of anti-blue light With, the effect of anti-ultraviolet can be played again, thus can preferably be protected by this eyeglass The eyes of people.Specifically, the effect of protecting film layer is each to inside protecting film layer Class film layer plays a protective role, and prevents from being scraped off damage；The effect of antireflection film layer is right The blue light being irradiated to lens surface filters, thus avoids the blue light infringement to eyes； Owing to antireflection film layer can cause the luminous energy of other wavelength light during filter blue light Loss, the effect of transmittance film layer is the light transmittance strengthening other wavelength light, more specifically Say, by chromic oxide layer, tantalum pentoxide layer, five oxidation three titanium layers, dioxies Change zirconium layer, radiation prevention film layer and the cooperation of these several Rotating fields of silicon dioxide layer, it is ensured that eyeglass Get a clear view while realizing anti-blue light；The effect of color-changing membrane layer is can be according to ultraviolet The strong and weak of line changes color, and by ultra-violet absorption or filtration, thus prevent ultraviolet Infringement to eyes；Therefore, by designing above lens structure, it is possible to prevent indigo plant simultaneously Light and the ultraviolet infringement to people's eyes, protect the health of people's eyes effectively.

In above-mentioned anti-blue light color-changing lens, described tantalum pentoxide layer is positioned at three oxidations Between two layers of chrome and five oxidation three titanium layers, described titanium dioxide zirconium layer is positioned at five oxidation three titanium layers And between radiation prevention film layer.Appropriate design by above film layer structure so that this eyeglass The effect of anti-blue light and anti-ultraviolet is best.

In above-mentioned anti-blue light color-changing lens, described transmittance film layer and color-changing membrane layer it Between there is stiffening layer.The effect of stiffening layer is the hardness improving variable color film surface, convenient Transmittance film layer is plated on color-changing membrane layer.

In above-mentioned anti-blue light color-changing lens, described protecting film layer for super waterproof membrane or Waterproof membrane.Produce the requirement of required hardness according to eyeglass, protecting film may select super waterproof membrane Or waterproof membrane, play waterproof and dustproof, anti-scraping effect.

In above-mentioned anti-blue light color-changing lens, the inner side of described substrate has stiffened successively Layer, transmittance film layer, antireflection film layer and protecting film layer.It is also adopted by above inside substrate Film layer structure, further increases the effect of this eyeglass anti-blue light and anti-ultraviolet.

Compared with prior art, this anti-blue light color-changing lens has the advantage that this eyeglass By design color-changing membrane layer, transmittance film layer, antireflection film layer, it is provided simultaneously with anti-indigo plant Light and the function of anti-ultraviolet, and translucent effect is good；It addition, in the sun, variable color Film layer can make colour of lens deepen, and makes light become softer, the most dazzling.
