Doctors do not recommend eye washing for normal people because the eye has its own endocrine environment and secretes its own tears to maintain the normal acid-base balance in the eye. If you wash your eyes with cleaning solution or water, it will cause changes in the internal environment of the eye, which will lead to a series of symptoms such as dry eyes and uncomfortable eye astringency in the long run. Therefore, it is not recommended to wash the eyes of normal people without special circumstances, and do not listen to the advertisements that eye washing is healthier and has benefits. Eye wash is not medically effective and has no good effect, so it is not recommended.
