Exposure to high doses of UV light over short periods can cause a very painful condition called photokeratitis. This is an inflammation of the cornea on the front surface of the eye. Essentially it is ‘sunburn of the eyes’, but thankfully the effects of photokeratitis are short-term. However, we may not be aware of the long-term effects of UV radiation because they are painless and develop gradually over a lifetime’s exposure to UV radiation. On the outer areas of the eyes, possible complications include skin cancers of the eyelid and discoloured swellings on the whites of your eyes known as pinguecula and pterygium. Within your eyes, UV damage may increase your risk of sight threatening conditions such as cataracts and macular degeneration.
The good news is that you can shield your eyes from this damage. As well as sunglasses, you can opt for clear prescription spectacle lenses with UV protection. Essilor Crizal UV lenses offer your eyes protection against damaging UV light from both the front and back surfaces of the lens. They provide the wearer with a SPF (sun protection factor) of 25, meaning that they are 25 times better protected against UV than without lenses.
