Sunglasses are not just to “look cool”, or be able to shield a bit of the sun. Some inexpensive glasses barely filter the UVs and we have to squint (hello wrinkles).
Prescription sunglasses are both stylish and protective. Not to mention they are adjusted to your eyesight, which adds to comfort.
When you think about how the sun can dry out plants, fade carpet color or furniture, and even blind you (when you drive!), you realize it’s necessary to put as much thought into the purchase as you would for regular prescription glasses.
