The Function Of Anti Blue Light Glasses

Anti blue light glasses can effectively reduce the sustained damage of blue light to the eyes. Through comparative testing with a portable spectral analyzer, the intensity of blue light emitted by mobile phone screens is effectively suppressed after using anti blue light glasses, reducing the harm of harmful blue light to the eyes.
Anti blue light glasses mainly reflect harmful blue light by coating the surface of the lens, or absorb harmful blue light by adding anti blue light factors to the lens substrate, thereby achieving the blocking of harmful blue light and protecting the eyes.
All anti blue light lenses using film reflection technology will reflect harmful blue light on the surface of the lens, while anti blue light lenses using substrate absorption technology will not reflect blue light. As shown in Figure 4, the glasses reflecting blue light above are anti blue light glasses.
