Extended data

We should also guard against "snow blindness" when it snows occasionally in the south.

Snow blindness, also known as "solar ophthalmia", is caused by the long-term reflection of a large area of snow and strong ultraviolet rays burning the outer cornea of the eye. Snow has a high reflectivity to strong light, especially the reflectivity of new snow is as high as 95%. When the eyes are stimulated by strong ultraviolet rays for a long time, the epithelial cells on the cornea and conjunctiva will be killed and then fall off, resulting in corneal opacity, unclear vision and snow blindness.

Experts pointed out that people who have been dealing with snow for a long time should wear protective sunglasses when going out after snow, and try to avoid staring at snow for a long time in strong sunlight. If "snow blindness" occurs, you should first wash your eyes with water or eye drops, then gently cover your eyes with an eye patch or a clean handkerchief and try to close your eyes and rest. The symptoms of "snow blindness" usually take 5 to 7 days to eliminate.
