Ultraviolet radiation levels increase nearer the equator, so residents in the Northern parts of Australia are at greater risk. UV levels are also greater at high altitudes. Since the human lens absorbs UV radiation, individuals who have had cataract surgery are at increased risk of retinal injury from sunlight unless a UV absorbing intraocular lens was inserted at the time of surgery. Individuals with retinal dystrophies or other chronic retinal conditions may be at greater risk since their retinas may be less resilient to normal exposure levels. Children are not immune to the risk of ocular damage from UV radiation.
Children typically spend more time outdoors in the sunlight than adults.
Solar radiation damage to the eye may be cumulative and may increase the risk of developing an ocular disorder later in life. Protection from UV radiation Ultraviolet radiation reaches the eyes not only from the sky above but also by reflection from the ground, especially water, snow, sand and other bright surfaces. Protection from sunlight can be obtained by using both a brimmed hat or cap and UV absorbing eyewear. A wide-brimmed hat or cap will block roughly 50 percent of UV radiation and reduces UV that may enter above or around the glasses. Ultraviolet absorbing eyewear provides the greatest measure of UV protection, particularly if it has a wraparound design to limit the entry of peripheral rays.
