The Hidden Dangers of UV Light: Why Eye Protection Matters
Sunshine lifts your mood and invites adventure, but its invisible ultraviolet (UV) rays can quietly harm your eyes. Whether you’re kayaking, hiking, or just relaxing outdoors, UV exposure can lead to serious eye problems—often without early warning signs.
How UV Rays Affect Your Eyes
UV light is a powerful form of radiation that penetrates eye tissues more deeply than visible light. Over time, this can increase your risk of several eye conditions:
Pterygium (Surfer’s Eye)
This wedge-shaped growth starts in the corner of your eye and may spread across the surface. While usually painless and non-cancerous, it can cause blurred vision or even block your pupil. Sun, dust, wind, and fumes all increase your risk.
Pinguecula
Long-term sun exposure can cause yellowish bumps on the white of your eye. Although often harmless, pinguecula can lead to irritation, redness, or blurred vision, especially for those who spend lots of time outdoors.
Photokeratitis
Too much UV—whether from sunlight or tanning beds—can cause this painful “sunburn” of the eye. Symptoms include pain, redness, swelling, and blurry vision. If you notice these signs, see an eye specialist right away.
Cataracts
Years of sun exposure can damage the proteins in your eye’s lens, causing it to cloud over. Cataracts are a leading cause of vision loss, affecting over 2.5 million Canadians—a number expected to double by 2031.
Eye Cancer
UV rays are also a risk factor for eye cancers like intraocular melanoma, which develops in the eye’s middle layer.
Easy Ways to Protect Your Eyes From UV
Wear sunglasses that block 100% of UVA and UVB rays—even on cloudy days.
Choose wraparound frames for extra coverage.
Add a wide-brimmed hat for more shade.
Limit sun exposure during peak hours (10 a.m. to 4 p.m.).
Avoid tanning beds and unnecessary artificial UV sources.
Get regular eye exams to catch problems early, even if you don’t notice symptoms.
