What causes dry eyes?

1. Bad eye habits

With the popularization of electronic products such as computers and mobile phones, people's eye habits have changed a lot, such as using computers for a long time, looking at mobile phones for a long time, etc. The smaller the screen, the greater the damage to the eyes. In addition, long-term exposure to air conditioning and air pollution can also cause symptoms such as dry eyes. White-collar workers, in particular, are more likely to suffer from dry eyes, which is mainly related to insufficient blinking when using computers. When people stare at a computer screen, the number of times they blink will invisibly decrease, thereby reducing the secretion of tears in the eyes. At the same time, the eyeballs are exposed to the air for a long time, the moisture evaporates too quickly, and the eyes become dry and uncomfortable, which can easily cause dry eye syndrome in the long run.

What eye drops to use for dry eyes

There are many reasons for dryness. If you overuse your eyes, it is recommended to use Zhenshiming (or Pearl Eye Solution). If not, then don't use the medicine indiscriminately, as it may have negative effects. Also, it is best to lie down for a while when the medicine is dripping so that it can take effect. Runjie is usually used when the skin is dirty, like trachoma.

What to do if your eyes are dry:

1. Blink more

Blinking is a protective nerve reflex action, and the tear layer can evenly apply tears to the surface of the cornea and conjunctiva to keep them moistened and not dry. Once the number of blinks decreases, the amount of tears will directly decrease, and the tear film exposed to the air will evaporate quickly and lose its protective power for the eyeball. When using your eyes for long periods of time, such as operating a computer, driving, reading, etc., remind yourself not to focus too much and take some time to blink. Most people blink once every five seconds, or about 20 times per minute.

2. Pay attention to eye hygiene

In life, it is recommended that everyone should always pay attention to the hygiene of their eyes, wash their hands frequently, and try not to rub their eyes with their hands. After using your eyes continuously for about an hour, it is recommended to take a proper rest. You can choose to close your eyes and look into the distance. For patients with oily secretions, debris, and shedding on the eyelids, it is important to maintain eyelid hygiene.
