Recently, Harbin, which has made locals call "you make me stranger", has become popular in the circle. Southerners have always had an innate yearning for snow, and they have fun having snowball fights, snowman pinching, and skiing. I would also like to remind everyone that the winter climate in the Northeast is cold and dry, so pay attention to keeping warm and eye health!
Behind the white snow, be wary of the "killer" of vision - snow blindness. Seeing snow for a short period of time does not have a great impact on the eyes, but if you need to play or work outdoors with snow for a long time, you should wear protective sunglasses with UV protection function, which is not only a fashion item, but also an important thing that can effectively block UV rays and prevent your eyes from being burned.
Don't worry too much if you accidentally experience "snow blindness", most people's snow blindness can be relieved or cured within 24-48 hours.
If there is a "snow blindness" situation, you can also take self-help
1 Change the environment in time, stay away from the light source, wash your eyes with eye drops or clean water, and then cover your eyes with an eye mask or towel to reduce the symptoms of conjunctival hyperemia, and close your eyes to rest.
2 If you wear ** glasses, contact lenses, etc., you must take them off, do not rub your eyes, avoid secondary injury, and finally go to the hospital in time.
3 For patients with severe symptoms of snow blindness or failure to alleviate it by taking the above measures, they should seek medical treatment in a professional eye hospital in time and receive it under the guidance of a doctor**.
