Quick Answer
Snow blindness often occurs due to prolonged exposure to glare from snow and ice without proper eye protection, leading to irritated and damaged corneas. This is a common issue among skiers, snowboarders, and polar explorers. It can cause severe eye pain and temporary blindness.
Causes of Snow Blindness
Snow blindness is primarily caused by ultraviolet (UV) radiation from the sun reflecting off snow and ice. This radiation can cause damage to the cornea, the clear layer at the front of the eye. Prolonged exposure to this radiation without adequate protection can lead to inflammation and irritation of the cornea.
Symptoms and Diagnosis
Symptoms of snow blindness typically begin within 30 minutes to an hour after prolonged exposure to UV radiation. They can include eye pain, redness, and sensitivity to light. In severe cases, snow blindness can cause temporary blindness or vision loss. Diagnosis is typically made based on a person’s symptoms and medical history.
Prevention and Treatment
To prevent snow blindness, it’s essential to wear proper eye protection, such as goggles or sunglasses with UV filtering lenses, when spending time outdoors in snowy or icy conditions. If you do experience snow blindness, seek medical attention immediately. Treatment typically involves applying artificial tears to help soothe the affected eye and reducing exposure to UV radiation. In severe cases, prescription medication or eye drops may be necessary to alleviate symptoms.
