Pinguecula: Due to sun uv exposure from childhood just about everyone gets changes of the collagen fibers near the cornea into elastic tissue which is yellowish. They are called pinguecula and by itself they are nothing to worry about. Protect your eyes with 100% uv block sun glasses so they do not get inflamed & progress to pterygium (growth over cornea). Get your eyes examined by an eye md every 4 years.
