What Is Snow Blindness? Misconceptions, Treatment, and Prevention, According to Travel Expert

Understanding What is Snow Blindness

Snow blindness, medically known as photokeratitis, occurs when harmful ultraviolet (UV) rays damage the surface of the eyes. Unlike common misconceptions, it doesn't cause blindness but creates temporary vision impairment and extreme discomfort. The condition is most commonly experienced in snowy environments, high-altitude regions, and areas with intense reflected sunlight.

How Does Snow Blindness Happen?

Sunlight reflects off snow and ice with incredible intensity, sometimes reflecting up to 80% of UV radiation. This reflected light can burn the cornea and conjunctiva, similar to a sunburn on your skin. Mountaineers, skiers, and travellers in snowy regions are most at risk.

Snow Blindness Symptoms

Travellers might experience intense eye pain, a feeling of sand or grit in the eyes, excessive tearing, difficulty keeping eyes open, temporary vision blurriness, headaches, and swelling around the eyes. These symptoms can quickly turn a dream vacation into a painful experience.

Snow Blindness Cure

Vikram Malhotra emphasises prevention as the most effective strategy for travellers. Wearing high-quality UV-protective sunglasses, choosing wraparound styles that block side light, using snow goggles with 100% UV protection, wearing wide-brimmed hats, and limiting exposure during peak sunlight hours are crucial steps to protect one's eyes.

Snow Blindness Treatment

If snow blindness strikes, experts recommend moving to a dark, cool environment, removing contact lenses, using artificial tears, applying cool compresses, taking over-the-counter pain relievers, and avoiding rubbing the eyes.

Snow Blindness Misconceptions

Many travellers mistakenly believe that snow blindness only happens in extreme winter conditions. In reality, it can occur in any bright, reflective environment, including beaches and high-altitude locations. Even on cloudy days, UV rays penetrate and can cause damage, making eye protection crucial year-round.

"In my 20 years of leading expeditions across the Himalayas," says Vikram Malhotra, "I've seen numerous travellers suffer from snow blindness. Many underestimate the power of reflected sunlight in mountain regions. Proper eye protection is as crucial as carrying the right gear."

Those most vulnerable include winter sports enthusiasts, mountain climbers, travellers to snow-covered regions, people living in high-altitude areas, and individuals with light-coloured eyes. The risk is particularly high for those spending extended time in environments with intense sunlight reflection.

Your eyes are your most valuable travel companions. Before starting your trip on winter adventures, investing in proper eye protection can save you from days of discomfort and potential travel disruptions.
