Abstract

The utility model relates to a blue light grade protection lens, comprising a transparent resin substrate, a hardening film disposed on the surface of the transparent resin substrate, and a first SiO2 film layer, a ZrO2 film layer, a second SiO2 film layer, an In2O3 film layer, a Ti2O3 film layer, a third SiO2 film layer, and a waterproof film layer disposed on the surface of the hardening film in sequence. Through adding the In2O3 film layer and the Ti2O3 film layer in sequence, the blue light grade protection lens simplifies film layer structure, and filtering effect for blue light with wavelength of 400-500 nm can reach 40-44%, or even higher, so the lens can effectively filter blue light radiation. The lens can reduce eye sting and hurt, reduce eye drying, eyestrain, and prevent cataract and maculopathy.

Description

Blue light level protection glass

Technical field

The utility model belongs to the technical field of optical material, and in particular, the utility model relates to a kind of blue light level protection glass.

Background technology

Blue light refers to that wavelength is the high-energy visible ray of 400～500nm.There is various injuries and impact to human eye in this light, because shortwave blue light has very high energies, can penetrate the through retina of crystalline lens, the harm of blue ray radiation is mainly reflected in the following aspects: (1) blue light illumination retina can produce free radical, and these free radicals can cause retinal pigment epithelium decline, thereby epithelial decline can cause photaesthesia cell to lack nutrient causes vision impairment, very easily cause macula retinae portion pathology, and macular diseases almost becomes the No.1 killer of global human eyesight.(2) blue light is injected eyeground after focusing on, focus does not drop on retina, but drop between retina and crystalline lens, this has just increased the aberration distance that light focuses within the eye, and distance between intraocular focus is the main cause that forms blurred vision, so injecting of blue light can aggravation aberration and dimness of vision degree, then eye muscle is overstretched, eye blood supply is overstretched, and ocular blood supply is strengthened, thereby increases the weight of fatigue.(3) in daily life, conventional LED lamp, computer and mobile phone etc. send blue light intensity and have approached blue light intensity in sunlight at noon, and back spectacle is very near, at this moment blue light on amphiblestroid injury and on the impact of melatonin secretion considerably beyond the exposure intensity of 1.3 lux blue lights, because blue light stimulates brain, thereby destroying hormone secretion balance, the generation that suppresses melatonin secretion and improve cortex hormone of aadrenaline directly affects sleep quality.Studies show that blue light is present in the light such as LED lamp, computer monitor, mobile phone, digital product, LCDs, super bath in a large number.In order to prevent almost ubiquitous study of blue light injury, be badly in need of a kind of blue light safety goggles really with anti-blue light effect of exploitation.

Utility model content

In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of blue light level protection glass.

Blue light level protection glass described in the utility model, comprises transparent resin substrate, on described transparent resin substrate surface, is provided with and adds dura mater, it is characterized in that: on dura mater surface, have successively a SiO in described adding ₂rete, ZrO ₂rete, the 2nd SiO ₂rete, In ₂o ₃rete, Ti ₂o ₃rete, Three S's iO ₂rete and membrane waterproofing.

Wherein, a described SiO ₂the thickness of rete is 285nm, described ZrO ₂the thickness of rete is 320nm, the 2nd SiO ₂the thickness of rete is 115nm, In ₂o ₃the thickness of rete is 85nm, Ti ₂o ₃the thickness of rete is 350nm, Three S's iO ₂the thickness of rete is 780nm.

Blue light level protection glass described in the utility model compared with prior art has following beneficial effect:

Blue light level protection glass rete of the prior art is 8～12 layers substantially, film layer structure complexity, and cost is higher, and its blue light filter effect that is 400～500nm wavelength for wavelength coverage generally only can reach 10～30% left and right; And blue light level protection glass described in the utility model is by introducing In ₂o ₃rete and Ti ₂o ₃rete, has not only simplified film layer structure, and can reach 40～44% to the blue light filter effect of wavelength 400～500nm, even higher, can effectively filter blue ray radiation, be conducive to reduce eyes stung acid swollen, minimizing glasses are dry and astringent, kopiopia, prevention and ARM.
