Thus,the anti-scratch layer is applied to the lens su***ce

The semi-silver plated su***ce reflects the light of about half,and let the other half of the light passing through direct ??.Typically,the mirror coating is gradual,paint and change the color depth from top to bottom gradually.The bottom and horizontally,more while allowing the light which can be enhanced sunglasses to light from the top of elasticity.This means that when you are driving,sunglasses,still you,while it possible to view the dashboard and means to block the sunlight.Sometimes paint is faded at the top and bottom of the color depth of the best lens,the center of the lens is clear.Important issue,paints,reflecting sunglasses is that the vulnerable.Obviously,we sunglasses manufacturers have not been able to be successful with a reflective film which is coated with a scratch-resistant layer now.Thus,the anti-scratch layer is applied to the lens su***ce is coated with a reflective film on the scratch layer.Anti-scratch protection layerGlass,is a natural anti-scratch,it is not a majority of plastic.To solve this problem,manufacturers,a series of methods,has developed a robust transparent layer of the coated su***ce film of the lens.Such films are perforated by the class of carbon and polycrystalline diamond sintered body of the material.The ionization process,a thin layer on the su***ce of the lens,please wear a very resistant membrane.Antireflection coatingA common problem is,back glare on the back of the light after he is reflected in your eyes is generated,is the emergence of sunglasses after glare.The effect of the anti-reflective protective coating is to reduce the reflected light lens.And anti-scratch protection layer,anti-reflective coating,a layer of the lens is very strong,very thin membrane.The refractive index of the antireflection film material between the air and the glass.This is roughly equal to the film strength of the inner su***ce and an outer su***ce of the reflected light.The thickness of the film when the inner and outer su***ces of the film,light of a wavelength of light reflected from a would cancel by destructive interference minimizes glare look like this 1/4 It is the degree.Anti-reflective coating is also the front face of the refractive lens,and are applied to several sunglasses to eliminate glare produced by the reflection lens and a "hot spot"UV coatingOne of several causes of the most serious eye disease,is as follows.
