Function of anti-blue glasses

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

Anti blue light glasses mainly reflect harmful blue light by coating on the lens surface, or absorb harmful blue light by adding anti blue light factor to the lens substrate, so as to block harmful blue light and protect eyes.

For the anti blue light lens using film reflection technology, because the harmful blue light is reflected, the lens surface will reflect blue light, while the anti blue light lens of substrate absorption technology will not reflect blue light. As shown in Figure 4, the glasses reflecting blue light above are anti blue light glasses
