Photokeratitis is a condition that can occur if your eyes are exposed to intense sunlight for a short period of time – on holiday, for example. While the condition is not permanent, it can cause pain and discomfort, a gritty sensation and extreme sensitivity to light.
If your eyes have been exposed to the sun over a number of years however, you could be at risk of developing cataracts or macular degeneration. Cataracts occur when the lens of the eye becomes cloudy, and they can be replaced with an artificial lens under local anaesthetic. Macular degeneration on the other hand affects central vision and unfortunately causes irreversible sight loss.
