Long-Term Effects of Repeated UV Exposure on the Eyes
While photokeratitis itself is usually temporary, repeated or intense exposure to ultraviolet (UV) light can have long-lasting effects on your eye health. Over time, UV damage can increase from photokeratitis to the risk of developing several serious eye conditions, including:
-
Cataracts
Prolonged exposure to UV-B radiation can accelerate the formation of cataracts—a clouding of the eye’s natural lens. Cataracts are a leading cause of vision loss worldwide and can be prevented with proper eye protection.
-
Macular Degeneration
The macula is the part of your retina responsible for central vision. Long-term UV exposure may contribute to age-related macular degeneration (AMD), a condition that causes blurred or reduced central vision and can impact your ability to read or recognize faces.
-
Pterygium
Also known as “surfer’s eye,” this is a non-cancerous growth of tissue on the white part of the eye that can extend onto the cornea. It’s strongly linked to UV exposure and can cause irritation or vision distortion.
-
Skin Cancer around the Eyes
The eyelids and surrounding skin are also sensitive to UV rays. In fact, skin cancer around the eyes—especially basal cell carcinoma—is more common among those with high sun exposure and inadequate eye protection.
Special Note: Protecting Children’s Eyes from UV Rays Leading to Photokeratitis
Children spend more time outdoors and are more sensitive to UV damage. Their lenses are clearer, allowing more UV light to reach the retina, which can cause photokeratitis or lead to the development of several serious eye conditions. Here are a few protective tips just for them:
- Provide UV-blocking sunglasses sized for kids
- Use wide-brimmed hats to shade their face and eyes
- Encourage shaded play areas when possible
- Lead by example—let kids see you wearing sunglasses and taking care of your eyes
Did You Know? UV Intensity Varies by Location and Season
- UV levels are highest between 10 a.m. and 4 p.m.
• Snow reflects up to 80% of UV rays, increasing exposure
• Water reflects up to 25% of UV rays
• UV rays are stronger at higher altitudes and closer to the equator
Conclusion
Photokeratitis is a painful yet preventable eye condition caused by overexposure to ultraviolet (UV) light. Whether from direct sunlight, reflection off surfaces like water or snow, or artificial sources such as welding arcs or tanning beds, your eyes need protection. If you are experiencing symptoms such as redness, blurred vision, tearing, light sensitivity, or a gritty sensation in your eyes, don’t ignore them; early care can prevent complications.
