Just after washing, I touched my contact lens with my wet hand and went blind.

I am not a title party, and this is not a shocking push.

Maybe many people, like me, used contact lenses in optical shops at first, and then used omnipotent Taobao.

But have you ever heard of the note "Don't get your contact lenses wet"?

One morning in June, 20 1 1, Irene Eccles woke up and found tears in her right eye. At first I thought it was a general problem, so I prepared some antibacterial eye drops, but the pain became worse and worse, so my sister had to go to the hospital for examination.

After several days of examination, she was told that she had acanthamoeba keratitis (AK), a rare but serious eye infection caused by microorganisms common in tap water, seawater and swimming pools.

This is a picture of the early stage of infection. If not treated in time, it will get worse immediately. The later pictures are horrible. Search for it yourself if you have the guts.

Later, because the medicine could not cure her sister's eyes, Exeter underwent a corneal transplant, but after 10 days, Exeter's eyes began to hurt again. During the inspection, he found that the Justice and Development Party had occupied the territory again. A year later, I had to have a second transplant. This time, although the pain disappeared, I couldn't see my right eye.

"When Irenie Ekkeshis's eyes began to itch, she didn't care and thought that she would be fine soon. But before long, her right eye was completely blind. The reason may be that she touched her contact lens with her wet finger. "

My sister said that she 12 years old began to wear contact lenses. She is a very cautious girl. She never wears contact lenses to swim or take a bath. She wears a sun hat. However, she still fell into the water, probably because she touched contact lenses before drying her hands.

Why not let contact lenses get wet? There is a simple reason. Water contains a large number of microorganisms, which are easy to cause eye infections when attached to lenses. ...

But many people don't care, because we don't think it's that serious.

This disease affects about 125 people in Britain every year-the vast majority of cases are related to the use of contact lenses.

Experts point out that many common eye infections are caused by unsanitary use of contact lenses. Acanthamoeba keratitis is the most serious one, which can make people blind within 24 to 36 hours at the earliest. Its common symptoms are green pus on the eyes after a few hours, pain, discomfort and fear of seeing the light.

You may be confused when you see this, because you seem to have been exposed to tap water for countless times in China, and it's nothing.

Some netizens explained that although the water from foreign tap water pipes can be directly drunk, foreign tap water is high-pressure reverse osmosis filtered water, and microorganisms can easily reproduce in low-pressure water networks. In China, most tap water is not suitable for direct drinking (chlorine bleach and disinfectant will be added), so we usually boil water before drinking. After boiling, inedible chlorine in water will volatilize and compounds will precipitate. Therefore, tap water in China is almost free of microorganisms.

However, there are similar cases in China. A 14-year-old girl wearing orthokeratology lenses (commonly known as OK lenses, that is, wearing them at night and picking them during the day) is also infected with Acanthamoeba, and she also washes her lenses with tap water (this is domestic tap water).

Girls have been wearing OK glasses for more than 3 years and have been at home since primary school. Every time a mother washes her daughter's glasses with cold boiled water, there is nothing wrong with it (the doctor pointed out that this is also an inappropriate cleaning method).

Until the girls who entered junior high school began to live on campus, because the time from self-study to turning off the lights in the evening was too short, everyone rushed to use the bathroom. If the action is slower and the hot water is used up, the girl washes the lenses with tap water and puts them in her eyes.

Later, she recalled that the lens was washed by tap water three or four times before it was infected with Acanthamoeba.

Last June, 5438+065438+ 10, the girl suddenly felt a special pain in her left eye, which seemed swollen. She dared not look at the bright light and soon her eyes became red. Just like the girl mentioned above, at first she thought it was an ordinary eye pain, but it didn't get better after using conventional eye drops, and she couldn't even see the biggest letter on the eye chart clearly.

The final diagnosis was acanthamoeba keratitis (AK), and the treatment was very painful. A disinfectant drops into the patient's eyes to kill insects, and it can't stop for 24 hours. At first, the doctor stipulated that the girl's condition could not be completely controlled, and she should drop it every 10 minute. The mother who is distressed by her daughter has to set an alarm clock and get up every once in a while to help her child take some medicine. Now girls can't attend classes to treat their eyes for the time being. The doctor said it would take another year or so.

The professor who treats girls said: "Acanthamoeba infection requires two conditions: first, protozoa have the opportunity to enter the eyes, such as washing eyes with tap water containing protozoa and cleaning contact lenses; Second, the cornea itself is damaged. Wearing contact lenses for a long time will inevitably cause some slight damage to the cornea, which provides an opportunity for Acanthamoeba to enter the eye for reproduction. " (/20 1702 10/n 480388529 . shtml)

Therefore, in any case, you should eat snacks when washing lenses. Don't risk swimming for beauty. Be careful when cleaning lenses when traveling abroad.

So, don't use water, my friend. Drink it, but don't use it on your contact lenses!

I have been doing experiments related to sewage recently. My doctor made a specimen for me the other day. I saw a group of lively microorganisms swimming around. I'm a little panicked without goggles. . . . . .

Hey, I said ... Do you feel a little itchy in your eyes?
