How to prevent dry and uncomfortable eyes
Modern people often use computers, mobile phones and other electronic devices for a long time, resulting in more and more common problems of dry eyes. So, how can we prevent dry eyes? Here's a detailed introduction from several aspects.

Keep eyes moist
1. Drink more water. Maintaining adequate water intake can maintain the water balance of the whole body, including the eyes. Drinking 6-8 glasses of water every day will help reduce the dryness of your eyes.
2. Use artificial tears. Artificial tears are eyedrops that simulate tears, which can be dropped into the eyes when the eyes are dry, providing moist and comfortable feelings for the eyes.
3. Avoid exposure to dry environment. The dry environment will lead to excessive evaporation of water from the eyes, causing dryness and discomfort. Try to avoid staying in a dry climate or air-conditioned room for too long. If you must stay in a dry environment for a long time, you can use a humidifier to increase the air humidity.
Reasonable eye use
1. Adjust the computer screen. The computer screen is more irritating to the eyes, so it is necessary to maintain an appropriate sight distance and angle. Adjust the brightness and contrast of the computer screen, and place the screen in the eye level position.
2. Do eye exercises. Focusing on the same point for a long time will lead to eye fatigue. You can use the rest time to do some eye movements, such as eye rotation, closing eyes to take deep breath, etc., to alleviate the fatigue of eye muscles.
3. Take 5-10 minutes off every hour. After using eyes for a long time, it is necessary to give them proper rest time. Every hour or so, stand up and walk around or close your eyes for a few minutes to rest, which will help alleviate the fatigue and dryness of your eyes.
Protect eye health
1. Pay attention to eye cleaning. Keeping eyes clean is the basic measure to prevent dry and uncomfortable eyes. Regularly clean the skin around the eyes with warm water every day to avoid the accumulation of oil and dirt around the eyes.
2. Avoid rubbing eyes with hands. Many people are used to rubbing their eyes with their hands to relieve dry discomfort, which often aggravates the problem. Because the hands are easy to carry bacteria, rubbing the eyes will cause eye infection, further aggravating the discomfort of the eyes.
3. Wash eyes regularly. For people who wear contact lenses for a long time, regular eye washing is an important measure to protect eye health. You can use the eyewash recommended by your doctor to wash your eyes, clean your eyes and contact lenses, and avoid bacteria breeding and infection.
Eye Hospital
When dry and uncomfortable eyes persist and cannot be improved by adjusting living habits, it is recommended to go to an eye hospital for professional doctor's help. Eye hospitals such as Peking University Eye Hospital and Shanghai Zhongshan Hospital Eye Department have professional ophthalmologists and equipment, which can conduct comprehensive inspection and treatment of eye problems.
To sum up, to prevent dry and uncomfortable eyes, it is necessary to keep the eyes moist, use the eyes reasonably, protect eye hygiene, and go to an eye hospital when necessary. Through these methods, we can effectively prevent dry and uncomfortable eyes and protect eye health.
