How fragile are human eyes?

Our eyes are the most vulnerable organs of human beings. In life, there are many things that will do great harm to it. Knowing these dangers will help to prevent them before they happen and better protect your eyes. The American magazine Good Housekeeping published an article about "10 eye damage" summarized by many ophthalmologists.

Go out without sunglasses. Dr Nai Acaru, professor of ophthalmology at the University of Illinois in the United States, said that too much ultraviolet radiation can easily burn the cornea and even lead to many eye diseases such as cataracts. So when you are outdoors, wearing sunglasses and a wide-brimmed hat can protect your eyes well.

Don't wash your face before going to bed. After running for a day, your face will be stained with a lot of dust and germs. If you don't wash your face before going to bed, it is easy to cause eye infections. In addition, the American Ophthalmology Association suggests that eye cosmetics such as mascara should be replaced every three months to avoid bacterial infection.

The air is too dry. Blowing, air drying, etc. It will accelerate the loss of water in the eyes and easily cause dry eyes. It is suggested to avoid rubbing your eyes with your hands, use a humidifier properly and wet your eyes with artificial tears. Addis Montag, a doctor of ophthalmology at Stanford University, reminded that artificial tears should be used less than four times a day. If your eyes are itchy, you can put artificial tears in the refrigerator and reuse them, which can better relieve the itching of your eyes.

Ignore photophobia. Dr Anne Sumer, an expert from the American Ophthalmology Association, said that many people think that flash, photophobia, pain, blurred vision or redness will disappear naturally. However, these may be eye disease signals from the body. If ignored, it is easy to aggravate eye diseases, make vision difficult to recover, and even have more serious consequences.

It's all eye drops. Dr Stephanie Marionix, an ophthalmologist at the American Academy of Ophthalmology, said that some eye drops can temporarily constrict blood vessels and eliminate red eye symptoms, but inflammation still exists. Repeated use of such eye drops will lead to redder eyes. Therefore, when the eyes are red and swollen, it is best to see a doctor in time to treat both the symptoms and the root causes.

Stare at the computer. Dr. Mario Nichols said that under normal circumstances, the number of blinks in one minute is 12~ 15. If you stare at the screen for a long time, the number of blinks will be significantly reduced, which will easily lead to eye diseases such as dry eyes, fatigue and myopia. Therefore, when using the computer, watching TV and watching mobile phones, you should always look up at the distance and let your eyes have a rest.

Wear contact lenses in the shower. Dr. Mario Nichols said that when taking a shower or bath, don't wear contact lenses, otherwise shampoo and shower gel will pollute the lenses and cause eye discomfort. In addition, in hot summer and windy spring, it is best to wear less contact lenses.

Swimming without goggles. When swimming or repairing furniture, it is best to wear goggles to protect your eyes. Otherwise, dirty water and fast-moving small objects may damage the cornea.

Smoking. Dr Ian Kona, professor of ophthalmology at the University of Pittsburgh School of Medicine, said that smoking 20 cigarettes a day would double the risk of cataract. Smoking also increases the incidence of age-related macular degeneration and myopia. This is because the oxygen inhaled by the human body is consumed when smoking, which leads to the decrease of blood oxygen, and the retina is particularly sensitive to hypoxia, which will inevitably lead to great loss of vision and even blindness in serious cases.

Do not check your eyes regularly. Dr montague said that even if you are not nearsighted or presbyopic, you should get into the good habit of seeing an ophthalmologist regularly. Especially for patients with hypertension and diabetes, you should always check your eyes.
