Ultraviolet (UV) radiation from the sun isn’t just harmful to your skin—it poses significant risks to your eyes as well. Prolonged exposure to UV rays can lead to a range of eye conditions that may impact your vision and overall quality of life. This article explores the link between UV exposure and eye diseases, while providing practical tips for protection.
Â
The Impact of UV Exposure on Eye Health
Short-Term Effects
- Photokeratitis: Often described as a “sunburn of the eye,” this painful condition occurs after intense UV exposure, causing redness, tearing, and temporary vision loss.
Long-Term Effects
- Cataracts: UV exposure accelerates clouding of the eye’s lens, leading to cataracts, one of the leading causes of blindness worldwide.
- Macular Degeneration: Chronic UV damage can contribute to the deterioration of the macula, the central part of the retina critical for sharp vision.
- Pterygium: This benign but potentially vision-impairing growth can extend over the cornea due to prolonged UV exposure.
Â
Who is at Higher Risk?
- Outdoor Enthusiasts: Hikers, skiers, and beachgoers often face increased UV exposure due to direct sunlight and reflective surfaces like water and snow.
- Children: Younger eyes absorb more UV rays, making proper protection vital during outdoor activities.
- People at High Altitudes: Higher altitudes mean stronger UV radiation, increasing risks for residents or travelers in such areas.

How to Protect Your Eyes from UV Exposure
Choose sunglasses labeled with 100% UV protection to shield your eyes from both UVA and UVB rays. Polarised lenses can also help reduce glare.
Use a Wide-Brimmed Hat
A wide-brimmed hat or cap can block up to 50% of UV rays, providing additional coverage for your eyes and face.
Limit Exposure During Peak Hours
UV radiation is strongest between 10 a.m. and 4 p.m. Limit outdoor activities during these hours, or seek shaded areas.
Wear Protective Contact Lenses
Some contact lenses offer UV protection, which can complement other protective measures like sunglasses.
Myths About UV Protection
Myth 1: Only Sunny Days Are Risky
UV rays penetrate clouds, meaning your eyes can still be exposed on overcast days.
Myth 2: Darker Lenses Offer Better Protection
Lens color doesn’t determine UV protection. Always check for a UV certification regardless of tint.
Conclusion: Protect Your Eyes for a Lifetime
Understanding the risks of UV exposure to your eyes and taking preventative measures is crucial for preserving your vision. By wearing proper eyewear and adopting UV-safe habits, you can enjoy the outdoors safely while safeguarding your eye health.
