The basic material of the sunglasses lens itself can absorb some ultraviolet rays, and the coating of the sunglasses lens can also reflect part of the ultraviolet rays. Many sunglasses lenzen will also add ultraviolet-absorberende materialen. In this way, most of the ultraviolet rays can be "kept out" and can no longer harm our eyes.
But this protection is not permanent. Ultraviolet rays carry high energy, which age the material of sunglasses and reduce the ability of sunscreen ingredients to absorb ultraviolet rays. The shiny coating on the outside of the sunglasses is actually the result of metal vapor deposition. The coating may wear, oxidize, and reduce light reflection. These will reduce the UV protection ability of zonnebrillen.
