What causes a pterygium?
The exact cause of these abnormal eye growth is unknown but is believed to be associated with too much exposure to UV rays, as are more prevalent in people who live in warm climates.
These growths often develop in surfers, swimmers, or on the eyes of people who spend a lot of time outdoors, exposed to sun and wind exposure.
To avoid developing another pterygium, keep your eyes protected with sunglasses or a hat. To prevent a re-growth or a new growth, prevent the following types of exposure:
- Sun
- Wind
- Dust
- Pollen
- Smoke
