Core Viewpoint - Snow blindness, medically known as "photokeratitis," is a temporary eye inflammation caused by prolonged exposure to ultraviolet light, leading to corneal epithelial cell damage. Group 1 - Symptoms of snow blindness require immediate action, including moving to a shaded area and applying a cold towel to the eyes to avoid further damage [1][3] - If protective eyewear is lost, sunglasses or eye masks can be used temporarily to reduce light exposure [3] - Artificial tears without preservatives can alleviate dryness and foreign body sensation, while antibiotic eye drops should be avoided unless prescribed by a doctor [3] Group 2 - Near-sighted individuals should refrain from wearing contact lenses during symptoms to prevent worsening, with frame glasses recommended as the preferred option [3] - If symptoms persist beyond 24 hours, medical attention is necessary to check for potential corneal epithelial detachment or retinal damage [3] - Treatment principles include using preservative-free artificial tears and possibly nutrient factors for corneal epithelium repair, with severe cases requiring appropriate antibiotic eye drops to prevent infection [4]
