# How do I protect my eyes from UV damage?

Ultraviolet (UV) radiation from sunlight can contribute to cataract, pterygium, pinguecula and some surface cancers. Protecting the eyes from cumulative UV exposure is an important part of long-term eye health.

## Protection strategies

Wearing sunglasses that block 100% of UVA and UVB, together with a wide-brimmed hat, significantly reduces the amount of UV reaching the eyes. Children and people spending long periods outdoors, on water or snow, benefit particularly from consistent protection.

- Choose sunglasses labelled with full UVA and UVB or UV400 protection
- Wraparound frames or side shields help limit light entering from the sides
- Contact lenses with UV filters provide partial additional protection but do not replace sunglasses
- Avoid direct viewing of the sun, including during eclipses
