Pterygium and Pinguecula Overview

The video discusses two common eye conditions: pinguecula and pterygium. It explains their causes, symptoms, and treatments. Pinguecula is a yellow spot on the eye caused by environmental factors, while pterygium, also known as surfer's eye, is a growth that can affect vision. Both conditions are linked to UV exposure and are more common in men and those living near the equator. Prevention includes wearing UV-protective sunglasses and hats. Treatments range from eye drops to surgery, depending on severity.
