Before letting your children run outside to build a snowman or hit the ski slopes, make sure their eyes are well protected. Sun and snow can be a dangerous combination for both the eyes and skin.

Sunlight Reflected in the Snow

Snow acts as a powerful mirror for sunlight and magnifies the effects of UV rays. As a result, the eyes are exposed to UV radiation bouncing back from the snow and shining directly from the sun. UV rays are even more powerful at higher altitudes and can penetrate through clouds.

Can I Get Sunburned Eyes?

Yes — the condition is called snow blindness, or photokeratitis. It is usually painful, causes extreme sensitivity to light, and can take up to two weeks to fully heal. Even a single day of playing outside in intense sun glare can cause snow blindness.

Symptoms of Snow Blindness

Symptoms include a stinging or burning sensation in the eyes, high sensitivity to light, blurred vision, watery eyes, and swollen eyelids. In rare cases, photokeratitis can even cause temporary vision loss.

How to Protect Your Eyes

Prevent overexposure by wearing sunglasses that absorb at least 95% of UV radiation when outdoors, no matter what time of year. Well-fitting UV-protective sports eyewear or ski goggles are ideal for winter activities.

How to Treat Sunburned Eyes

• Stay out of the sun for a few days until symptoms subside.
• Wear sunglasses even indoors for comfort.
• Place a cool, damp cloth over closed eyelids while resting.
• Do not wear contact lenses until the eyes return to normal.
• Artificial tears can help keep the eyes moistened and promote healing.
