UV light is an electromagnetic radiation with a wavelength from 100 nm to 400 nm, shorter than that of visible light but longer than X-rays. It is present in sunlight.
Strong and penetrating "Blue light " in wavelength 380~400 can reach retina and cause various eye problems (like cataract, macular degeneration etc).
* Cut off whole wavelength UV light ,provide 100% protection. Avoid skin aging and darkness , decrease skin cancer risk.
* Decrease artificial light damage , such as HID head light. Upgrade driving comfort - super clarity , low haze.
* Heat rejection and energy saving.
* Use UV light to flash on counterfeit detection area, you'll see UV fluorescence
* when there's UV400 film in between, UV light is absorbed by our film and you will not see UV fluorescence.
