In Modesto and Riverbank, we often remind patients that sunglasses aren't just for style—they're essential protection. Most people understand the dangers of sunburned skin, but did you know your eyes can get sunburned too?
One patient came in after a long weekend at the lake—no sunglasses, no shade, just hours of sun and water reflection. By that evening, her eyes were red, watery, and painfully sensitive to light. She didn’t realize it, but she was experiencing photokeratitis, also known as sunburn of the eye.
It’s more common than most people think—and completely preventable.
What Is Photokeratitis?
Photokeratitis happens when the cornea (the clear, front surface of the eye) is overexposed to ultraviolet (UV) rays. Just like sunburn on your skin, it damages surface tissues of the eye, causing pain and inflammation.
Symptoms usually appear a few hours after exposure and may include:
- Red, gritty, or watery eyes
- Blurry vision
- Sensitivity to light
- Burning or the feeling of “sand in the eyes”
- Temporary vision loss in more severe cases
While the effects are typically temporary, repeated UV exposure can lead to long-term damage, such as cataracts and macular degeneration.
Common Situations Where Eye Sunburn Happens
You don’t have to be sunbathing on the beach to suffer from eye sunburn. Here are a few everyday situations that increase your risk:
- Boating, fishing, or swimming without proper UV eye protection
- Snow sports, like skiing or snowboarding, especially at high altitudes
- Hiking or outdoor sports during peak sun hours
- Using tanning beds without protective goggles
- Looking directly at the sun, even briefly
Anywhere there’s bright sunlight or reflective surfaces—like water, sand, or snow—your eyes are vulnerable.
How to Protect Your Eyes from UV Damage
Keeping your eyes safe in the sun is simple, effective, and important. Here’s what we recommend:
1. Wear Sunglasses Year-Round
Choose sunglasses that:
- Block both UVA and UVB rays
- Have a wraparound frame or large lenses for full coverage
- Are labeled UV400 or higher
UV exposure happens even on cloudy days, so don’t save your shades just for summer.
2. Wear a Wide-Brimmed Hat
A hat can reduce the amount of UV radiation reaching your eyes by up to 50%.
3. Limit Sun Exposure During Peak Hours
The sun’s rays are strongest between 10 a.m. and 4 p.m. Try to seek shade or wear full sun protection during this time.
4. Use Polarized Lenses for Outdoor Activities
Polarized sunglasses reduce glare from reflective surfaces like water and snow—great for boaters, skiers, and beachgoers.
