Sun Exposure in the Triangle and the Concern of Cataracts

stock images old guy glassesThe Triangle’ warm and sunny seasons may keep the flowers and grasses growing, but over time, excessive exposure to sunlight can possibly harm the eyes, even causing cataracts.

A cataract is a clouding of the lens of the eye. The lens is located behind the iris (colored portion) of the eye and as eyes age, the lens becomes less flexible and thicken. These changes can cause tissues to break down and clump together, clouding the lens. This condition can create depth issues when walking steps, can make it harder for night driving, and over time can blur and worsen sight.

Seeing through cloudy lenses is like looking through a fogged-up window. The main cause of cataracts is aging, but excessive UV radiation from those beautiful blue sky days is another major factor.

Cataracts account for almost 15 million blind people worldwide, according to the World Health Organization. WHO estimates about 20 percent, or 3 million, of those cases are likely caused by UV radiation from the sun’s rays.

Preventing cataracts is a challenge. There are several risk factors known for cataracts, including diabetes, excessive alcohol consumptions, family history, high blood pressure, obesity and smoking.

Raleigh and Durham residents with these risk factors should be especially careful when heading to the beach, working in the yard, or attending a baseball game. Park Ophthalmology specializes in cataract care, but prevention is the best cure! Follow these three guidelines to prevent sun damage to your eyes:

  • Stay out of the sun: While some sunlight is good for the body, wear a hat and cover up while outdoors to prevent too much exposure to both skin and eyes. A tree or an umbrella are not a guarantee against damage, but a wide-brimmed hat can significantly reduce eye exposure to UVB radiation.
  • Wear protective eyewear: Always wear “shades” when outside. The sunglasses must block 99% or 100% of UVB and UVA rays. Get more tips for buying the right sunglasses.
  • Wear clothing that blocks or screens the sun’s rays: Combine the clothes, sunglasses and of course, sunscreen for the best eye protection.

Regular eye exams will help in the assessment of both healthy eyes and the beginnings of cataracts. The human eye is too important. Exams prevent surprises.
