1. • Light-filtering chemical added to them

     • Polarised lenses have a light-filtering chemical added to them. The molecules are organised precisely to prevent parts of the light from passing through the lens. It works in a similar way to a blind hanging from a window. The light is only able to move through the openings of the blind.

   Do polarized sunglasses come with prescription lenses?

   • Both polarized and non-polarized sunglasses are available with prescription and non-prescription lenses. Polarized prescription lenses usually involve an additional charge on top of the included, basic lens option, but this isn’t always the case. Some manufacturers include polarization as a standard feature or offer it free of charge.

There is a subtle way to tell the difference between standard sunglasses and polarised ones. Hold the sunglasses in front of a reflective surface, and look through one of the lenses.

   Put simply, polarised sunglasses are designed to reduce glare from light-reflecting surfaces like water, glass or snow – as well as protect your eyes from harmful UV rays. Standard sunglasses will protect your eyes from bright light, and in most cases, offer UV protection — but they aren’t always able to reduce glare.
