Summer is a great time to plan a vacation and special outdoor activities. Before you begin planning how you and the family will spend the sunny days ahead, here is some information that will help you safeguard your eyes and maintain healthy sight not just this summer but for a lifetime.

While most people are aware of the effects of Ultraviolet (UV) radiation on the skin, few are aware of the damage that UV radiation can cause to the eyes. As a consequence people do not take adequate measures to protect their eyes. Though the intensity of UV radiation is highest in summer, India being a tropical country receives high levels of UV radiation right through the year!

Effects

The skin has a capacity to adapt to UV radiation by producing melanin (tan) but the human eye does not have such a capacity. Prolonged exposure to UV can result in several debilitating eye diseases and conditions such as Photokeratitis (sunburn of the cornea), Pterygium (a growth of tissue that extends onto the clear cornea blocking vision) and Cataract (clouding of the lens inside the eye), which occurs over a period of many years.

Wide-brimmed hats and sunglasses are not enough to protect your eyes. Examine labels of sunglasses carefully to ensure that the lenses provide 100 per cent UV blockage when worn. Wrap-around sunglasses are a good option, as they prevent lateral exposure. Poor quality eyewear (sunglasses or prescription lenses) is harmful; so invest in good quality eyewear.

Children spend a lot of time outdoors and are more vulnerable to the damaging effects of UV. In fact they receive up to 80 per cent of their lifetime UV exposure before the age of 18.

Appropriate eyewear

Wearing appropriate eyewear for outdoor activities is very important. Photochromic lenses adjust to the level of UV light they are exposed to, going from exceptionally clear indoors to comfortably dark outdoors. They provide 100 per cent UV blockage and protection from glare and can be worn both indoors and outdoors.

Polarised lenses are recommended for activities like skiing, surfing and diving. Swimming goggles protect the eyes from waterborne bacteria and swimming pool chemicals. Polycarbonate lenses are impact resistant and shatter proof making them a very good option for children.

These measures will provide adequate protection for your eyes. In case of injury or eye infections contact your eyecare practitioner immediately.
