Pterygium: Prevention

Prevention is the best and really only current “cure.”


Research shows that adequate protection of the eyes against sunlight may reduce the rate of this disease. 


Prevention starts at a young age. Keeping kids (as young as kindergarten and primary school age) out of the sun or wearing sunglasses &/or (preferably and wide brimmed hats, helps prevent pterygium especially if there is a genetic predisposition and especially if near the equator.


Sunglasses should be worn whenever outdoors as early as possible. 


When purchasing a pair of sunglasses, ideally they are labelled with a sticker or tag that states compliance with the ANSI standard or bought from a very reputable company.


This standard gives the safety and performance requirements for lenses and frames. 


Also look for an EPF UV rating of either 9 or 10, where the lenses transmit almost no ultraviolet radiation.  When protecting the eyes from ultraviolet radiation, wrap-around and close fitting sunglasses are the most effective type. Consult your eye care professional when selecting appropriate sunglasses.
