Who needs eye pain, a headache or blurred vision on a glorious day in the snow? Exactly: no one. That’s why it’s important to know about the condition that can cause all of the above (and worse): snow blindness.
Together with the eyewear experts of Oakley, we have compiled some useful information on how to prevent snow blindness and protect your eyes. Let’s go!
Essentially, snow blindness, or arc eye, is a sunburn on your eyes. Photokeratitis – that’s the medical term for snow blindness – is caused by too much exposure to ultraviolet (UV) light. Just like your skin, your eyes are sensitive to UV rays – that’s why we squint when the light gets too bright.
When too much UV light hits your cornea, it can get inflamed and irritated. Unfortunately, UV exposure can be a problem during some of the activities we love the most. As the sunlight reflects off the snow during skiing or snowboarding, it intensifies – causing damage to your eyes.
By the way: Snow blindness is more common in higher elevations, as cold temperatures can contribute to photokeratitis.
No, snow blindness can occur in any environment with increased UV exposure. For instance, the sunlight intensifies when reflecting off snow, water or sand.
What’s more, light from blowtorches or tanning booths can also lead to photokeratitis. That’s why snow blindness is also sometimes referred to as “welder’s flash” – frequently affecting people who use welding equipment for a living.
The tricky thing about snow blindness is that it can sneak up on you. Just like with sunburned skin, you often only notice the first symptoms when it’s too late.
Usually, the first symptoms of snow blindness occur several hours after UV exposure. They can include:
Keep in mind: Although snow blindness mostly causes minor vision problems like seeing halos around light sources, it can sometimes also cause temporary loss of vision.
Fortunately, snow blindness is also similar to sunburned skin in that it will mostly heal on its own within one to two days.
However, while it’s usually not serious, it may be a good idea to see an ophthalmologist if symptoms are severe.
Although snow blindness will usually recede by itself, there are a couple of things you can do to alleviate the symptoms:
Important: Try not to rub your eyes – this will only make things worse!
There’s only one way to protect your eyes from too much UV exposure: good-quality ski goggles or sunglasses. Top-class ski goggle manufacturers such as Oakley offer full-coverage UV protection – and their products are worth the money!
After all, too much UV exposure can result in long-term damage to your eyes. For instance, resulting conditions include cataracts or eye cancer.
