Anti blue light Round Safe-Glasses SA12168

Glasses that contain lenses specifically designed to reduce the amount of blue light that reaches the eye.
These lenses filter blue light rays to help prevent them from entering your eye and causing potential damage.
These glasses are made of special plastic that is very elastic, and it is almost impossible to break, so by bending the temple arm we can adjust them to our head so that they are as comfortable as possible.
