The Ambermatic Ray-Bans

As hard as it might be to believe, sunshine is on the way. No, really.

So when it comes, you'll want to ensure that you're totally ready for the heat. Yes, this means it's finally time to throw away that pair of sunglasses you sat on last year.

Since it's the 75th anniversary of Ray-Ban, it's perfect timing for you to indulge on a pair of their finest. This summer, they're releasing a limited edition capsule collection of four pairs of Aviators but with a novel touch.

The sunglasses will all utilise Ambermatic lenses, a style that was first released in 1978. The Ambermatic lens is yellow and darkens depending on light and temperature. This change from yellow to brown actually helps block glare and highlights outlines and shaped. It also looks pretty damn cool.

You can pick up a pair for £178 at Sunglass Hut.
