Most sunglasses lenses are curved. Some gently. Some dramatically. Getting the right amount of curve into a lens is not that difficult. Getting a curve into a lens while retaining its optical clarity however, is notoriously tricky. Then Polaroid gave it a go.

Traditional manufacturers use 'vacuum-forming' to curve their lenses. This technique results in lenses which temporarily warp your perception of sizes, shapes and distances. This distortion is subtle and takes place often without you even realizing - things just aren't quite how they seem.

And since your eye is forced to compensate for the lenses' sub-standard optical performance, you are at huge risk of eye strain if you wear poor quality sunglasses.

We've developed some cool lens technology that gives clearer, truer vision with no shape-shifting side-effects. We call it Thermofusion™ Technology.

It's a unique optical lens manufacture process which optically fine-tunes the lens while curving it. Polaroid's Thermofusion™ Technology creates lenses which are optically perfect, allowing the eye and the wearer to relax.

Distortion is a thing of the past with Polaroid lenses.
