The role of blue light blocking glasses

Anti-blue light glasses can effectively reduce the continuous damage of blue light to the eyes. Through the comparative detection of the portable spectrum analyzer, after using the anti-blue light glasses, the blue light intensity emitted by the mobile phone screen has been effectively suppressed, reducing the damage of harmful blue light to the eyes.

Anti-blue light glasses mainly reflect harmful blue light through the coating on the lens surface, or add anti-blue light factor to the lens base material to absorb harmful blue light, thereby realizing the blocking of harmful blue light and protecting eyes.

Any anti-blue light lens using film reflection technology reflects harmful blue light, so the surface of the lens will reflect blue light, while the anti-blue light lens with substrate absorption technology will not reflect blue light.
