Quick Answer
Symptoms requiring immediate medical attention include severe pain, blurred vision, double vision, and vision loss. If left untreated, these symptoms can lead to permanent damage or even blindness. Seek medical help right away if you experience any of these severe symptoms.
Understanding Snow Blindness
Snow blindness, also known as photokeratitis, is a painful and potentially serious condition caused by exposure to UV radiation from snow and ice. When UV radiation hits the cornea and conjunctiva, it damages the tissue and leads to inflammation and pain. This condition is often seen in individuals who spend extended periods outdoors in snowy conditions without proper eye protection.
Symptoms and Severity
Symptoms of snow blindness typically begin within 6-24 hours after exposure and may include redness, itching, tearing, and sensitivity to light. As the condition worsens, symptoms can progress to include severe pain, blurred vision, double vision, and vision loss. In severe cases, snow blindness can lead to corneal ulcers, vision loss, and even blindness if left untreated.
Prevention and Treatment
To prevent snow blindness, wear protective eyewear that offers UV protection rated 400 or higher. Sunglasses with UV protection and goggles specifically designed for snow sports can offer adequate protection. If you experience symptoms of snow blindness, seek medical attention immediately. Treatment typically involves rest, lubrication, and pain management. In severe cases, medication may be prescribed to reduce inflammation and prevent infection.
