Blepharoplasty is a surgical procedure that repairs droopy eyelids. This technique is often performed for aesthetic reasons and may involve removing excess skin, muscle, and fat to tighten the skin around the eyes, thus achieving a radiant, youthful appearance.
Besides making you look older, severely sagging skin around your eyes can reduce your peripheral vision, especially the upper and outer parts of your field of vision. So, in addition to aesthetics, blepharoplasty also has a functional purpose.
