Quick Answer
Snow blindness, also known as photokeratitis, is a painful eye condition caused by prolonged exposure to snow glare. To spot signs of snow blindness in others, look for squinting, eye pain, or sensitivity to light. Be aware of people shielding their eyes or avoiding direct sunlight.
Recognizing Symptoms
Identify potential snow blindness by observing unusual behavior around the eyes. Look for signs such as squinting, tearing, or excessive blinking. Also, note if someone is covering their eyes or avoiding direct sunlight. In severe cases, you may see redness, swelling, or a gritty sensation in the eyes.
Determining Severity
Evaluate the severity of snow blindness by asking the person about their symptoms. Ask about eye pain or sensitivity to light. Also, assess their ability to see in bright conditions. If they’re having trouble seeing in the snow or are avoiding light, it’s likely they’re experiencing snow blindness. In severe cases, the person may have white or bloodshot eyes.
Treatment and Prevention
Prevent snow blindness by wearing protective eyewear with UV protection when spending extended periods in snowy conditions. If you suspect someone has snow blindness, have them remove their contact lenses and seek shade or wear sunglasses with a UV filter. Administering pain relief such as ibuprofen or acetaminophen can help alleviate symptoms, but medical attention should be sought immediately in severe cases.
