Can you open your eyes in the sea?

OK. The sea water is salty.

Your tears are also salty, both of which are alkaline

It may be a little uncomfortable at first. The eyes will feel swelling.

But in fact, it's okay to go into the seawater.

It is important to pay attention to hygiene.

Living by the sea for 20 years! Of course, you can, when you first swim, you will not be able to see clearly, so it's good to get used to it!

Yes, unless you want to get your cornea replaced.

wo I think it's okay, there might be pain, let's start

Yes, but I don't want to see anything.

Due to the sensitivity of the eyes, when a foreign object enters, the conditioned reflex closes the eye. Therefore, beginners who are familiar with water generally start from opening their eyes in the water and can get used to it within 10 minutes.

When the water is clean, keep your eyes open. But it's uncomfortable. The main reason is that the concentration in the eyeball is high in fresh water, and the water penetrates outward.

The main reason why the human eye cannot see anything in water is that the refractive index of water is much larger than that of air, and the function of the refractive system in the eyeball cannot focus on the center of the retina normally, as in severe myopia.

Why some people can open their eyes in the water, experts give the answer, everyone can!

Of course, I grew up by the sea, but I had to adapt.

I'm sorry to tell you that opening your eyes in the water doesn't come close to recovery.

Unclean water can cause eye inflammation, and opening your eyes in clean sea water can also have some antiseptic effect, but your eyes will be a little red at that time.

1.Rust on water pipes is very harmful to the eyes.

2.Although the tap water is disinfected and filtered, there are still bacteria in it, and the water company can only ensure that there are not many bacteria at the end of the pipe network. The tap water that comes out actually contains trace amounts of bacteria such as E. coli.

3.In addition, tap water is sterilized with chlorine water, which contains a small amount of hydrochloric acid, when the tap water is just out of the faucet, there should be residual chlorine (as well as Ca, mg, Cl plasma), although only a few tenths of a ppm, when you wash your eyes, it will enter the eyes, it cannot be ruled out that there is a slight impact on the delicate tissues such as the cornea, so your eyes will be red.

The eyes are very fragile, and over time there will be problems, if you really want to rinse, you should also use some saline to rinse, or if it is convenient, you can buy some eye drops to drip very comfortable, and it is not expensive, remember.

So try not to wash your eyes with tap water, otherwise it will hurt your eyes.
