How to Choose Blue Light Glasses?

Anti Blue Light Glasses are mainly achieved through substrate absorption, film reflection, or substrate absorption+film reflection technology. Adding anti blue light factors can affect the transmittance of the lens to some extent. Wearing such anti blue light lenses in dark environments can reduce contrast sensitivity by 2.4% to 9.6%. Therefore, maintaining good transmittance while preventing blue light is also an important indicator for evaluating lens quality.

The role of glasses in preventing blue light is to reduce the damage of harmful blue light to the retinal Photoreceptor cell of the fundus to a certain extent, which cannot prevent myopia fundamentally.
