Is snow blindness a risk when participating in winter sports?

Understanding Snow Blindness

Snow blindness, also known as photokeratitis, occurs when the eyes are exposed to intense ultraviolet (UV) radiation from snow and ice. This can cause painful eye irritation, blurred vision, and even temporary blindness. In extreme cases, snow blindness can lead to corneal ulcers and even permanent vision loss.

Precautions and Prevention

To prevent snow blindness, wear sunglasses or goggles that provide 100% UV protection. Choose goggles that wrap around the eyes to prevent UV radiation from entering from the sides. Apply a lip balm or sunscreen with a high SPF to protect the skin around the eyes from wind and sunburn. In areas with extremely high UV radiation, consider wearing a face shield or a ski mask to protect the eyes and skin.

Symptoms and Treatment

If you experience any symptoms of snow blindness, such as pain, redness, or blurred vision, seek medical attention immediately. In the meantime, remove any contact lenses and apply a cold compress to the affected eye. Do not rub the eyes, as this can exacerbate the condition. If symptoms persist or worsen, seek medical attention from an eye care professional.
