Problems solved by technology

However, the lower part of the glasses is a colorless and transparent area, which cannot effectively control the transmission of short-wavelength visible photons in visible light, and cannot reduce the damage of short-wavelength photon radiation to the retina of the eye.

specific Embodiment 1

[0045] The anti-blue light driving goggle lens in this specific embodiment consists of two parts: a substrate containing an ultraviolet light absorber and an evaporated film layer. The substrate is a refractive lens made of polycarbonate containing a short-wave visible light absorber, or it can be made of polymethyl methacrylate, allyl diglycol carbonate and diisopropyl peroxycarbonate copolymer. Any kind of prepared refractive lens. The vapor-deposited film layer is composed of three layers of alternately stacked layers, from the inside to the outside are SiO 2 film, ZrO film and SiO 2 The film layer has a thickness of 145nm.

[0046] SiO in this specific embodiment 2 The film layer is a low refractive index film layer, and the ZrO film layer is a high refractive index film layer.

[0047] The short-wave visible light absorbers in this specific example are disperse yellow, disperse blue and disperse red. Such as figure 1 As shown, due to the different content, the subst...

specific Embodiment 2

[0050] The anti-blue light driving goggle lens in this specific embodiment consists of two parts: a substrate containing an ultraviolet light absorber and an evaporated film layer. The substrate is a refractive lens made of polymethyl methacrylate containing a short-wave visible light absorber, or it can be made of polycarbonate, allyl diglycol carbonate and diisopropyl peroxycarbonate copolymer. Any kind of prepared refractive lens. The vapor-deposited film layer is composed of five layers of film layers stacked alternately, from the inside to the outside are SiO 2 film, ZrO film, SiO 2 film, ZrO film and SiO 2 The film layer has a thickness of 195nm.

[0051] SiO in this specific embodiment 2 The film layer is a low refractive index film layer, and the ZrO film layer is a high refractive index film layer.

[0052] The short-wave visible light absorbers in this specific embodiment are disperse yellow, disperse blue and disperse red. Due to the different contents, the sub...

specific Embodiment 3

[0053] The anti-blue light driving goggle lens in this specific embodiment consists of two parts: a substrate containing an ultraviolet light absorber and an evaporated film layer. The substrate is a refractive lens made of allyl diglycol carbonate and diisopropyl peroxycarbonate copolymer containing short-wave visible light absorbers, or it can be made of polycarbonate or polymethyl methacrylate. Any kind of prepared refractive lens. The vapor-deposited film layer is composed of five layers alternately stacked, from the inside to the outside, the TiO2 film layer and the SiO2 film layer are alternated, and the thickness is 150nm.

[0054] The short-wave visible light absorbers in this specific embodiment are disperse yellow, disperse blue and disperse red. Due to the different contents, the substrate is divided into gray strong light blocking area, blue-green main viewing area and yellow-green enhancing area from top to bottom. There are three parts in the transparent area. ...

Abstract

The present invention discloses kind of spectacles and its making method, ad is aimed at providing a kind of driver's protective spectacles capable of resisting blue light and its making method. Said lens is characterized by that it is formed from two portions of substrate containing UV light attractant and deposited film layer, and said substrate is made up by using organic high-molecular polymer containing short-wave visible light absorbent, and is divided into three portions of gray area for resisting strong light, bluish green main visual area and yellow or yellowish green ant-reflective area from top to bottom, and the deposited film layer is formed from at least one layer of film with low refractivity and at least one layer of film with high refractivity which are alternatively overlapped. Its making method includes the steps of tray dyeing, washing, drying, solidifying and vacuum evaporation, etc.

Description

technical field [0001] The invention relates to glasses and a manufacturing method thereof. More specifically, the present invention relates to an anti-blue light driving goggle lens and a manufacturing method thereof. Background technique [0002] Ordinary sunglasses: It can filter out ultraviolet light and reduce the transmittance of visible light. Generally, the transmittance of sunglasses is below 30%. Using sunglasses while driving in the daytime or on sunny days can protect the eyes. The rate is too low to affect the visual effect. [0003] Polarized sunglasses (that is, Polaroid glasses): In the case of satisfying Brewster's angle, most of the reflections can be eliminated, which is very beneficial to vision. Since the filter of the polarized lens is to eliminate the component of one direction in the incident light wave, The result is that the transmittance is reduced. At present, the transmittance of polarized glasses is between 32-14%. Such transmittance is only s...
