UV risk factors

"No one is immune to sunlight-related eye disorders. Every person, regardless of their background is susceptible to ocular damage from UV radiation that can lead to impaired vision.

Any factor that increases sunlight exposure of the eyes will increase the risk for ocular damage from UV radiation. Individuals whose work or recreation involves lengthy exposure to sunlight are at greatest risk.

Since UV radiation is reflected off surfaces such as snow, water and sand, the risk is particularly high on the beach, while boating, or in mountain areas. The risk is greatest during the mid-day hours, from 10 am to 3 pm, and during the summer months. Ultraviolet radiation levels increase nearer the equator, we are luckily far from away from it, remember holidays though, especially ones to Africa etc. 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.

Iris colour can pose a potential risk as well. Light blue coloured irides can block less UV than dark brown irides, resulting in more UV exposure by the tissues of the eye."
