Can a pterygium be prevented?
While it may not be possible to completely prevent a pterygium, there is compelling evidence to suggest that properly protecting the eyes from sunlight can help to lower the chance of a pterygium developing.
Steps that can prevent the development of pterygium
It’s important to keep children who are not yet in kindergarten or primary school out of the stronger midday sunlight. To protect younger children from excessive sunlight exposure, they should be placed in a stroller equipped with an awning.
If avoiding the sun isn’t feasible, they should wear a wide-brimmed hat, and wear suitable sunglasses as early as possible. Children should then consistently wear sunglasses whenever they are outside, once they reach primary school age.
Maintaining eye moisture may also help, especially for those who are frequently in dry or windy environments. Using lubricating eye drops can help keep the eyes hydrated, but further advice should be sought if dry eye symptoms are becoming more persistent.
Regular eye check-ups can also help to monitor any changes in eye health.
Finding a suitable pair of sunglasses
Generally, when buying sunglasses, you should make sure that they are marked as compliant with Australian Standard. Australian Standard outlines the performance criteria for lenses and frames.
You should also look for an Eye Protection Factor (EPF) UV rating of 9 or 10, indicating that the lenses allow almost no ultraviolet radiation to pass through. The rating is established by the Australian Radiation Laboratory, and provides a level of protection that exceeds the requirements set by the Australian Standard.
If you need more help to find a suitable pair of sunglasses that adequately protect your eyes from UV ray exposure, we recommend consulting with your optometrist or ophthalmologist.
