Whether it's cruising down groomed slopes or venturing into backcountry trails, skiing provides a unique combination of physical activity and breathtaking landscapes.
However, amidst all the excitement, one hazard often overlooked by skiers is snow blindness.
Snow blindness, medically known as photokeratitis or ultraviolet keratitis, is a temporary but painful eye condition caused by overexposure to ultraviolet (UV) light.
It primarily occurs in environments with high-altitude snow or ice, where the sunlight reflects off the white surfaces, intensifying its effects on the eyes.
Snow blindness occurs when the eyes are exposed to excessive UV rays, causing damage to the cornea, a transparent front part of the eye.
The following factors contribute to the occurrence of snow blindness:
1. UV rays reflection
Snow and ice have high reflectivity, leading to increased exposure to UV rays.
On a sunny day, the intensity of UV rays can be up to 80% higher on a slope compared to ground level.
2. Lack of eye protection
Failing to wear proper eye protection, such as goggles or sunglasses, leaves the eyes vulnerable to direct UV exposure.
The symptoms of snow blindness usually appear several hours after exposure and can persist for up to a few days. Common signs include:
1. Eye irritation: Redness, tearing, itching, or a foreign body sensation in the eyes.
2. Blurred vision: Loss of clarity in vision, making it difficult to see details.
3. Sensitivity to light: Increased sensitivity to bright lights or sunlight, leads to discomfort.
4. Gritty feeling: A sensation of having sand or dust in the eyes.
Fortunately, snow blindness can be prevented by taking appropriate precautions. The following preventive measures can help mitigate the risk:
1. Wear UV protective goggles
Invest in goggles or sunglasses with UV protection that block out both UVA and UVB rays.
Opt for wrap-around styles that provide full coverage, minimizing exposure from the sides.
2. Use polarized lenses
Consider using polarized lenses that reduce glare, providing further protection for the eyes.
3. Use eye drops
Artificial tears or lubricating eye drops can alleviate dryness and discomfort caused by snow blindness and support the healing process.
4. Seek shade and rest the eyes: Take regular breaks in shaded areas or indoors to minimize UV exposure while skiing.
If snow blindness occurs, the following self-care treatments can be applied:
1. Give your eyes a break
Rest the eyes by closing them or using a cool compress to relieve inflammation.
2. Avoid bright lights
Dim the lights in your surroundings and avoid direct exposure to bright lights.
3. Stay hydrated
Drink plenty of water to promote natural eye moisture and healing.
4. Seek medical attention if symptoms persist
If the symptoms worsen or do not subside within a few days, consult a healthcare professional specialized in eye care.
