Polarized Lenses
Sunlight does reflect in every direction, but if it strikes a flat surface, both vertical and horizontal polarized light will be formed. The first type of light will benefit your eyes, whereas the latter has a negative impact; it is magnified before reaching your eyes, causing blinding glare and eye strain.
Normal sunglasses are designed to protect your eyes against UV lights and reduce the amount of light entering the eyes. Unfortunately, they cannot block the horizontally polarized light.
On the other hand, besides all common features that normal sunglasses have such as anti-UV, staining, coated scratch-resistance, polarized sunglasses are equipped with a special thin filter or a so-called polarized film. This functions as a curtain, blocking and absorbing the dangerous light rays while only allowing beneficial ones, which cause no harm for the eyes, to pass through.
