Ultraviolet Rays: A Hazard to Our Vision

Ultra violet rays, more commonly known as UV, are rays from light which humans cannot see and feel. Excessive exposure to UV rays is a danger have been linked to premature skin ageing, cataracts, cancer, crow’s feet, macular degeneration and pinguecula.

Most people are aware that the sun is the main source of UV rays. What we do not realize is that many other mediums around us also produce UV rays, such as computer screens, television, light bulbs, even your mobile phone. UV rays are still at work even on cloudy days or when sitting under the fluorescent light.

In fact, today’s modern world where we are surrounded by technology exposes us to UV rays 365 days a year!

To protect our skin, many people practise the habit of applying sunscreen or long-sleeved tops and long pants when heading outdoors or in the office all day long. But how many would have thought of protecting the eyes from harmful UV rays?


A pair of good sunglasses can shield your eyes from harmful UV rays. When indoors, glasses that are coated with UV protection is recommended especially for those who are in front of the computer all day long. After all, your eyes are the windows to your soul!

The United States Food and Drug Administration also recommends purchasing light bulbs with a double coat to cut the intensity of UV rays indoors.

Left unprotected, UV rays can cause  eye diseases such as:

PTERYGIUM – UVB is related to the formation of pterygia, a raised, wedge-shaped growth of the conjunctiva that can grow over the cornea and affect vision.

CATARACTS – UV accelerates the appearance of cataracts, which causes a partial or complete loss of transparency of the crystalline lens.

PREMATURE AGEING – UV damages skin and causes up to 90% of visible premature ageing. About 5 – 10% of skin cancers occur on the eyelid.

PINGUECULITIS – UV causes a benign, yellowish growth on the conjunctiva that may cause irritation and dryness called a pinguecula. Pingueculitis develops when the pinguecula becomes acutely inflamed.
