What are the functions of blue light blocking glasses? Blue light blocking glasses are glasses that prevent blue light from irritating the eyes. Special blue light blocking glasses can effectively isolate ultraviolet rays and radiation and can filter blue light, suitable for use when watching computers or TV phones. In this issue, Yancheng Glasses has compiled information on the role of anti-blue light glasses for everyone, hoping to help everyone.
As early as 1966, Nell and other studies found that blue light irradiation can cause damage to retinal cells, resulting in decreased vision or even loss of vision. Among them, short-wave blue light with a wavelength of 400-450 nanometers is the most harmful to the retina. Blue light irradiating the retina will generate free radicals, and these free radicals will lead to the decline of retinal pigment epithelial cells, and the decline of epithelial cells will lead to the lack of nutrients for light-sensitive cells and cause vision damage, and these damages are irreversible.
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 through the lens base material to absorb harmful blue light, thus 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. As shown in the figure below, the glasses that reflect blue light on them are blue light blocking glasses.
