Anti-reflective and the UV Coating of the Cheap Fake Oakley Sunglasses

Anti-reflective and the UV Coating of the Cheap Fake Oakley Sunglasses. Speaking of the structure of the Oakley sunglasses, here is the continued story of the last passage posted on last Friday. Apart from the polarization, the specular reflection and the anti-scratch coating, there are also anti reflective coatings and the anti- uv protective coatings which belong to the structure of the Fake Oakley sunglasses.
Ok, let's start with the anti reflective coating: the most common problem of the cheap Oakley sunglasses is the glare, which is a light reflects to your eyes after arriving in the lens. The anti reflective coating is to reduce the reflection of the light to the lens. Just like the anti-scratch coating, the anti reflective coating is a layer of very strong and thin film on the lens. The refractive index of the anti reflective coating material is between the air and the glass. This makes the inner surface of the film and the intensity of the reflected light of the outer surface almost equal. When the thickness of the film is about a quarter of the wavelength of light, the light reflected from the inner surface and the outer surface will offset each other by means of destructive interference, thereby it can maximally reduce the glare you will see. The anti reflective coating is also coated on the front surface of the refractive contact lenses and some Oakley sunglasses to eliminate the "heated point" generated by the lens reflex ".
Ultraviolet light is one of the main causes of some of the most serious eye diseases. It has been divided into two categories depending on the frequency and wavelength: ultraviolet A and ultraviolet B.
As a natural eye protection mechanism, the cornea of the eye can absorb all the ultraviolet B and the vast majority of the ultraviolet A. However, there are still some part of the ultraviolet A can reach the lens. Long time absorption of ultraviolet A can lead to cataracts, a small amount of ultraviolet A through the cornea reach the retina can lead to retinal macular degeneration, and macular degeneration is the leading cause of blindness in the elderly over 65 years old. Long term exposure to the strong ultraviolet radiation can cause eye cancer or actinic keratitis, that is, the retinal burns. This often occurs in outdoor reflective light from winter snow in a sunny day due to the very strong snow glare, which is usually called chionablepsia.
Cheap Knockoff Oakley Sunglasses have an excellent UV-protective coating, which can eliminate the ultraviolet radiation. That is being said, you have to make sure that your fake Oakley sunglasses can filter two to one ultraviolet radiation at 100%. The label of the sunglasses should be marked with the exact degree of UV protection the sunglasses can provide, and what you need is 100% of the protection.
