About Polarized Lenses


Polarized sunglasses were first invented by Polaroid, or more specifically Edwin Land, the founder of the Polaroid Corporation, and first launched in the USA in 1935.


Polarized vs non polarized

Polarized lenses are different to standard sunglass lenses; they have a special film either sandwiched between two other layers of the lens or applied to the front of a lens. What this special film does is eliminate glare reflecting off a surface like a pavement, road, water or snow.

Benefits of polarized sunglasses

Polarized lenses benefit you by blocking glare and only allowing useful vertical light to enter so you can see much more clearly. Glare makes it difficult and uncomfortable to see and can cause eye strain. It also distorts the true colour of objects and makes them harder to distinguish. With a polarized lens you will see light in its pure state. Objects will appear more defined, sharper and naturally coloured. Instead of squinting to minimise glare, a polarised lens will allow your eyes to see colours with true clarity and reduced eye strain or fatigue.

Glare also causes a mirror-effect on water. As a polarized lens will eliminate glare on the water it means you will be able to see down below the water surface.
