#2. Invest in your glasses—both sun and otherwise

In the sun — Look for sunglasses with more opaque lenses and both UVA and UVB protection. They'll keep you from squinting, which will help you avoid wrinkles and protect the delicate skin around your eyes from sun-induced discoloration. (Even the most diligent SPF-appliers often forget to apply it there, says Ranella Hirsch, MD, a board-certified dermatologist in Boston). The bigger the frame, the better.

For everyday — As vision gets less sharp, other muscles in your eye area pitch in to help you focus, says Hirsch, which makes lines around the eyes worse. The right prescription can solve the problem.
