What causes eye growths?
It is not exactly clear what causes these growths to develop, but it is believed there is a genetic component combined with a history of excessive sun exposure. It has been found that people who live in very sunny regions nearer to the equator develop these growths most often. Pterygia affects millions of people’s eyes and can cause chronic irritation, redness, and tearing. In severe cases, it can cause severe astigmatism or blindness.
