You've heard that ultraviolet (UV) rays from the sun present a risk, but did you know human-made sources can also do harm? The Canadian Centre for Occupational Health and Safety says that workers most at risk include welders, construction workers, farmers, hair stylists, lab workers, and lighting technicians, to name a few. Many employers and workers don't realize their eyes are being jeopardized.
Long term UV exposure can cause premature aging of the eyes. As the population grows older, that exposure creates even bigger problems. According to the Canadian Association of Optometrists, macular degeneration is the leading cause of blindness in North Americans over age 55, and UV exposure is thought to be linked to an increased risk for this eye disease.
Heed the warnings. In addition to a welder's "flash burn" (burning of the cornea), other conditions from UV exposure include:
* Cataracts - permanent clouding of the lens. A comprehensive eye exam is the only way to determine if you have a cataract.
* Photokeratitis - causes watering eyes and blurred vision from an inflamed cornea
* Pterygium - a growth on the 3 and 9 o'clock positions on the white part of the eye extending into the cornea.
* Skin cancers - these are commonly found on or around the skin of the eyelids
Our optometrists perform a complete analysis of your UV risk during each comprehensive eye exam, including a determination of whether there is any evidence of current damage from UV exposure. We can recommend various options to protect your eyes and reduce the risk of acute as well as long-term eye health and vision problems.
Don't forget about your kids! Some studies show that children and teenagers may receive up to 80 percent of their lifetime exposure to UV light by the time they reach the age of 18 years. The eyes of young people are particularly at risk for UV damage in the early years.
