Blue Light Filter Lenses
BLUE LIGHT FILTER LENSES
The part of light that can be detected by the human eye is called visible light. "Blue light" is the most energetic visible light, with a wavelength between 400-500nm. LED screens of TVs, smartphones, tablets, and other 3C products all emit blue light, and modern people’s exposure to blue light is gradually increasing. Blue light filter lenses are coated with a special reflective film on the lenses to reflect part of the blue light, creating a blue light filtering effect.
UV420 BLUE LIGHT FILTER LENSES
In addition to improving the blue light filtering effect, UV420 can also improve the shortcomings of traditional blue light filtering lenses. Different from traditional blue light filtering lenses, UV420 can effectively block 90% of blue light, such as lenses with severe yellow cast, severe reflection, ghosting. UV420 is a progressive upgrade of lens material to absorb blue light, eliminating the need for a blue light filtering coating film. There is no reflection problem, the reflection is reduced, the lens transmittance is high, and the imaging quality is improved.
