A pterygium is an elevated, wedged-shaped bump on the whites of the eye. It can grow onto the cornea. Though it’s commonly called “surfer’s eye,” you definitely don’t have to be a surfer to get a pterygium. But being at a higher elevation with more UV exposure increases your risk for getting it. Most pterygium are benign, but they can cause discomfort and blurry vision.
