With the very bright sunshine and high UV levels currently being experienced, you may be finding that your current sunglasses are letting in glare at the edges.
This can make it uncomfortable to go out in the sunshine, particularly if your eyes are sensitive to glare.
The best sunglasses for blocking out glare are the 7eye AirShield and the Ziena Eyewear collections. These sunglasses are not only a close fitting, wraparound shape, but they also have a protective gasket around the inside of the rims that blocks peripheral glare very effectively.
