The Dangers of UV Rays on Your Eyes
Have you considered the effects of UV rays on your eyes when outdoors? Prolonged exposure can lead to several common eye conditions over time. Don't wait until it's too late to take action. Read on to learn how wearing sunglasses can help prevent long-term damage and protect your vision. You'll gain insight into how the sun impacts sensitive eyes or those with existing conditions. We'll also explore why sunglasses are especially important for older adults and their age-related needs. Arm yourself with knowledge so your next pair of shades does more than just look stylish.
Common Eye Conditions Caused by Sun Exposure
UV radiation from the sun can cause damage to your eyes over time. Exposure to UV rays has been linked to several eye conditions, like cataracts, macular degeneration, and pterygium.
Cataracts
Cataracts form when the lens of your eye becomes cloudy, causing blurred vision. UV radiation exposure is a major risk factor for developing cataracts. Over time, the proteins in your lens break down and clump together, blocking light from reaching the retina. Cataract surgery is often required to restore vision.
Macular Degeneration
Macular degeneration is a leading cause of vision loss, damaging the macula which is responsible for sharp, central vision. UV radiation exposure and blue light damage the light-sensitive cells in the macula over time. Macular degeneration causes blind spots, blurriness, and vision loss in the center of your visual field. Although incurable, some treatments may slow the progression.
Pterygium
A pterygium is a growth on the white part of your eye (sclera) that can spread onto the cornea. Prolonged UV radiation exposure, especially in areas closer to the equator, is a significant factor in pterygium development. As the growth spreads, it may interfere with vision or irritate the eye. Removal surgery is often recommended if vision is affected or the growth is unsightly.
Protection from Sunglasses
Protecting your eyes from UV radiation and sun damage is simple. Wear sunglasses that block 100% of both UVA and UVB rays. Look for sunglasses that specifically say they block 100% of UV rays. Large framed and wrap-around sunglasses also help block light from entering around the frames. Wearing sunglasses, in addition to broad-brimmed hats and limiting sun exposure during the middle of the day, can help prevent long-term eye damage and vision loss. Your eyes will thank you.
