What causes dry eyes and what are the ways to eliminate them?

Office workers' eyes are prone to dryness due to long-term exposure to computers. So what causes dry eyes? Let’s take a look below.

What causes dry eyes ? Dry and itchy eyes are common in life! This is more common in young people and white-collar workers who sit in front of computers for a long time. The following editor will answer them one by one for you!

What causes dry and itchy eyes?

1. Changes in tear film and dry eyes

As autumn approaches, not only the skin becomes dry, but the eyes also become dry. There is a layer of tear film on the surface of the eye, which is secreted by the lacrimal glands, meibomian glands and conjunctiva. It covers the cornea and conjunctiva, protects the cornea and conjunctiva and keeps them moist. It has the effect of disinfection and sterilization, and can also wash away some foreign matter. For people with dry eyes, the quantity or quality of tears secreted by the lacrimal glands will decrease, affecting the stability of the tear film on the surface of the eyeball, resulting in symptoms such as dry eyes, photophobia, itching, red eyes, and fatigue.

2. Staring at the computer and applying eyelashes are also the root of trouble

Dry eyes aren't just about the weather. In addition to seasonal changes, the modern working environment and special occupational requirements are also important pathogenic factors, such as frequent computer viewing, long periods of eye use, and lack of sleep. These are also important reasons why young white-collar workers frequently encounter dry eyes. Staring at the screen for a long time at close range will reduce the frequency of blinking, and the tear film is formed when people blink. If you do not blink for a long time, the tear film will naturally rupture. When the tear film ruptures, the cornea is exposed to the air and will become dry.

For example, many fashionable women like to paint their eyelashes by applying some chemical ingredients to the roots of their eyelashes, which is actually right at the opening of the meibomian glands. If the opening of the meibomian gland is blocked by something, it cannot secrete fluid normally, so meibomian gland dysfunction will occur, leading to unstable tear film.

3. Dry eyes ≠ conjunctivitis

Many people think that their conjunctiva is congested due to keratitis infection, and use anti-infection eye drops, but the condition does not improve for a long time. After a check by an experienced ophthalmologist, it is found that the patient has dry eyes and the wrong medicine was used. In some hospitals, such misdiagnosis also occurs from time to time. In fact, dry eye is a sterile disease and cannot be treated as infectious keratitis or conjunctivitis due to symptoms of conjunctival congestion. If antibiotic eye drops are used indiscriminately, it will lead to an imbalance of intraocular flora, which will weaken the eye's ability to resist infection in the long run.

4. Dry eyes can also cause frequent tears

Dry eyes do not mean that the eyes are dry and without water. On the contrary, many patients with dry eyes will often shed tears. If a person suffers from dry eye syndrome, the basal tear secretion is low, and the cornea and conjunctiva are dry, causing dryness, burning and foreign body sensation in the eyes. These symptoms will also stimulate the lacrimal glands to reflexively secrete a large amount of tears in a short period of time, exceeding the load of the lacrimal drainage system and causing paroxysmal tearing. #p#Subtitle#e#

What to do if your eyes are dry and itchy

Dry and itchy eyes can be treated with eye drops, such as ofloxacin eye drops, combined with sodium cromolyn eye drops, which have anti-inflammatory and antipruritic effects. At the same time, eye fatigue should be avoided to avoid aggravating the symptoms. The cause of eye fatigue is generally related to the secretion of tears, which should attract your attention, and you should take extra care of your eyes. The most convenient and effective way is to add some eye-nourishing foods to your diet.

1. Use eye drops with caution for dry eyes

Ophthalmologists remind young computer fans that relying solely on eye drops to relieve eye diseases will not have any therapeutic effect, and once drug resistance develops, the use of eye drops will be of no help. There is currently no specific drug for the treatment of dry eye syndrome. To reduce dryness of the eyes, the dosage of eye drops is also important. It should not be used too frequently, and it is best not to exceed 6 times a day. Some people are eager to be cured and get into the habit of using eye drops frequently, even several times an hour, which actually aggravates the symptoms.

Dry eyes are not a terrible disease. If you have any problems with your eyes, you should go to the hospital first and let the doctor provide correct treatment and advice. Depending on the severity of dry eyes, doctors may prescribe medication or surgery, both of which are aimed at conserving and replenishing tears. Mild dry eyes only require artificial tears.

2. Simple ways to eliminate dry eyes

First, you need to moisturize your eyes and avoid staring at them. Instead, blink your eyes frequently, keeping the blink rate at 15-20 times per minute.

Second, ironing the eyes. First, rub your hands together, rub them until they are warm, then press your palms against your eyes for 20 seconds, and repeat three times.
