Do you feel the same way when you are in front of the computer for a long time? For example, your eyes are swollen and itchy. At first, you thought something had entered your eyes, but later you felt that your eyes were dry and stinging, and you were afraid of light and tears? This is the "dry eye" that plagues the majority of white-collar workers, and the root cause is the computer.
There are 1 people who have been operating computers for a long time in Japan, and the ratio in China is 5: 1. When we are addicted to the computer, the decrease of blinking times reduces the lubricant and tears secreted by our eyes, and the cornea is not fully wetted, which leads to dry eyes and discomfort, which will lead to dry eyes over time. In the dry season, coupled with spicy, alcohol and tobacco stimulation, endocrine disorders and other conditions, the symptoms will be aggravated.
Preventive measures
Blink more, for example, when operating a computer, force yourself to blink more than 5 times per minute, because blinking is very important to protect your eyes, it can give the lens and iris muscles in a tense state a chance to exchange positions, thus ensuring that your eyes are properly lubricated.
Let your eyes wander. Let your eyes rest for 5 minutes every hour you watch the computer. You can do other things, or simply close your eyes and rest and massage the skin around your eyes with your hands.
Pay attention to hydration. Drink more chrysanthemum tea in the office and put a glass of water on the table to increase the humidity of the surrounding air. If there is air conditioning and heating in the room, it is best to use a humidifier. Reduce the time of wearing contact lenses when operating the computer, try not to wear contact lenses, and switch to ordinary myopia glasses; When the eyes are sour, dry and blurred, you should see a doctor in time.

The reason why ultraviolet ray is called the "target organ" of eyes by ophthalmologists shows that it is a dangerous enemy that hurts eyes. The eye is the most sensitive part to ultraviolet rays, which can widely absorb ultraviolet rays of various wavelengths, among which ultraviolet rays with a wavelength of 280 nanometers are the most harmful to the cornea and can cause ultraviolet adenoconjunctivitis; Ultraviolet rays with wavelength of 290-400 nm can damage the lens, which is the pathogenic factor of cataract. Studies have shown that the daily sunshine 1 hour will increase the risk of cataract 10%.
Preventive countermeasures:
Choose a pair of sunglasses with anti-ultraviolet function for yourself in spring and summer. Medical research has proved that neutral glass and gray lenses are the best sunglasses. Too deep sunglasses are easy to let the eyes receive more ultraviolet rays, which is not the right choice.
People who wear contact lenses can choose contact lenses with anti-ultraviolet function, which can filter out 90% ultraviolet rays. If they wear sunglasses again, the security level will be higher.
The midday sun is the most poisonous and does great harm to the skin and eyes. Avoiding going out is the best way. Danger: ★★★★★
Draw eyeliner, brush mascara, wear false eyelashes ... How many hidden dangers are hidden behind beauty?
At present, the practices of perm eyelashes and grafting eyelash, which are popular in beauty salons, worry ophthalmologists: cold perm essence and special glue are special cosmetics, which are very irritating to eyes, and may lead to corneal burns and serious eye atrophy. In addition, cosmetics such as mascara and eyeliner are easily contaminated during production or use. For example, Fusarium solani is often found in mascara, which can easily cause corneal mycosis. As for makeup, it is common for dust particles to fall into eyes, and allergic conjunctivitis can easily occur if it is not handled well.
Preventive countermeasures:
Pay special attention to makeup: it is best to close your eyes when removing dust; When applying mascara and wearing false eyelashes, you should move gently and avoid pulling hard.
Try to choose waterproof cosmetics to avoid inflammation caused by cosmetics infiltrating into eyes when sweating or getting wet in the rain.
Once the cosmetics are expired or contaminated, stop using them immediately; People with allergies must have an allergy test before using new cosmetics.
If cosmetic particles accidentally fall into your eyes, don't rub them at will. Wash your eyes with pure water immediately, or go to the hospital in time according to the damage of your eyes. Danger: ★★★★
"The eyes are the windows of the soul", and it is easy to see a person's happiness or sadness through the eyes. But little known is that the eyes are also pressure organs, and bad mood and great pressure will in turn affect the operation of the eyes.
When people have negative emotions such as tension, anxiety and depression, the secretion of pituitary and adrenal hormones will be relatively reduced, which will make the visual transmission and visual information processing functions of both eyes at a low level, which will directly lead to the uncoordinated contraction and relaxation steps of lens and eye muscles, and eventually lead to a series of symptoms such as headache, nausea, eye swelling and blurred vision. This will happen, which is called "binocular visual dysfunction". If you have an eye examination at this time, you will not find any organic lesions in your eyes, let alone medication, but you can recover through some training, emotional counseling and rest.
Preventive measures
For most people, the key to preventing visual dysfunction is to keep a good mood and get enough sleep.
