A virtually invisible filter can be built into lenses to eliminate the amount of reflecting light that enters the eye. Polarized lenses not only reduce glare, they make images appear sharper and clearer, increasing visual clarity and comfort. Available for prescription and non-prescription sunglasses, polarized lenses can be worn indoors by light-sensitive people, including post-cataract surgery patients and those continually exposed to bright sunlight through windows.
Most polarized sunglasses provide UV protection which is important to maintaining healthy eye sight. Just as we put on sunscreen to protect our skin, it’s critical that we protect our eyes from UV rays too.
