What is dry eye

What is dry eye syndrome? Many friends will have such questions when they first hear about this disease. This is normal because this disease is a symptom that has only appeared nowadays. From its literal meaning, we can see that the so-called dry eye syndrome is actually dry eyes. People who often play with computers and mobile phones are prone to dry eye syndrome.

Dry eye syndrome is a common disease among young people today, but some patients have more obvious symptoms while others are less obvious. When many patients encounter this situation, they generally choose to use anti-fatigue eye drops to relieve the symptoms, but it cannot be cured.

The number of patients with dry eyes is relatively high among office white-collar workers. This is mainly reflected in the fact that in healthy eyes, the main and accessory lacrimal glands will naturally secrete tears to lubricate the eyeballs. If you face the computer for a long time, your eyes will be too focused on the display screen, causing you to blink less and your tears to evaporate quickly. In addition, we usually watch TV, drive at night, stay up late, and read. In addition, offices are now equipped with air-conditioning systems, so the humidity is low and the air is not circulating, which accelerates the evaporation of tears. If you happen to wear contact lenses, it will make matters worse, and this is the main cause of acquired "dry eyes syndrome".

In addition, dry eyes are also a common problem after excimer laser surgery. Many patients experience dry eyes, foreign body sensation and other dry eye symptoms after PRK and LASIK surgery. During the examination, it was found that the amount of tear secretion decreased and the tear film breakup time was shortened for a period of time after the operation. Therefore, a dry eye examination should be performed before surgery, and patients with more severe dry eyes should avoid surgery.

The symptoms of dry eyes manifest in many aspects and there are many reasons. For example, many office workers go to ordinary pharmacies to buy eye drops on their own because they are busy, and very few people can go to professional hospitals for treatment. There are also many people who put eye drops into their eyes to save trouble. If they feel temporarily comfortable, they think that everything is fine. In fact, such irresponsible behavior will only cause greater damage to the eyes. In fact, some of the eye drops we commonly use contain preservatives, hormones, and antibiotics. Long-term use can cause irreparable damage to the eyes! For example, chloramphenicol can cause leukopenia and even aplastic anemia.

After knowing what dry eye syndrome is, I hope that friends who overuse their eyes can realize the harm of this disease and pay attention to eye protection in daily life. If dry eyes occur, it is best to do eye exercises or close your eyes and rest for a while, which can relieve the symptoms of dry eye syndrome.
