Is eyewash necessary?
There are such products on the market:
Pour the potion into a small plastic cup, buckle it on your eyes, shake it up and down, and blink your eyes. The purpose is to make the potion "wash" your eyes. It seems that the flocculent is washed out !
This is the eyewash. It is said to keep eyes moist and healthy, relieve eyes’ discomfort and eyes’ dry, conjunctival injection, pain and other symptoms.
So the question is, is eyewash really so magical ?
In fact, the main component of most eyewash is water or saline, the main function is to clean eyes surface.
But, our eyes do not need additional washing normally.
When blinking, a small amount of tears will be evenly smeared on the surface of eyeball, which can protect and clean the eyeball. The barrier function of the corneal epithelium itself can also resist the invasion of bacteria or viruses.
Frequent use of eyewashes can easily disrupt the balance of the ocular surface, disrupt the self-cleaning function of eyeball itself, and induce dry eye or conjunctivitis.
In the advertisement, the so-called "bright eyes after washing, the white floccules that really wash out may be the mucin that protects the eyes."
Believe me, most doctors do not recommend frequent use of eye washes for healthy people.
