You bought your cheapie sunglasses from a sidewalk vendor.
The delicate skin around your eyes is extremely thin and requires extra attention. Surprisingly, even people who are careful about sun protection often forget to put sunscreen in that area, says Hirsch, which can worsen wrinkles and discoloration. The right pair of sunglasses can serve as another line of defense, but only if they have UVA/UVB protection, as well as lenses opaque enough that you don't squint in bright light (which can exacerbate frown lines and eye wrinkles, adds Hirsch).
