Pinguecula and pterygium (sometimes called surfer's eye) are growths on the front of your eye. They grow on your conjunctiva (the clear, thin tissue that lines the inside of your eyelids and covers the white of your eye). They may be caused by too much sun, wind, dust, or just dry eyes.
For a pterygium:
Most of these growths don’t cause any symptoms
Sometimes, the growth can irritate your eye and cause problems with your vision if it covers a lot of your cornea
Doctors may give you artificial tears or corticosteroid eye drops or ointment
If a pterygium gets big enough to bother you or becomes inflamed again and again, doctors may do surgery to remove it
