What causes itchy tear glands?

The lacrimal gland is an important part of our body and is the main way for the eyes to secrete tears. The lacrimal gland is generally connected to the eyes, and some of it is exposed, so it is easy to be infected by bacteria and cause itching symptoms. The symptom of itchy tear glands is most likely caused by eye inflammation, such as conjunctivitis and keratitis. The occurrence of these inflammations will affect the normal secretion of tears.

Eye inflammation causing itchy and tearful eyes

Tearing and itching of the eyes are mostly related to eye inflammation. If you suffer from eye inflammation such as conjunctivitis, allergic conjunctivitis, keratitis, trachoma, etc., the nerve fibers that control the eye muscles will be stimulated or compressed by the inflammation and become infected. The normal amount of tears secreted cannot completely flow into the nasal cavity and flow out of the eyelids, resulting in eye discomfort symptoms such as itchy eyes and tearing.

Countermeasures: Go to the hospital's ophthalmology department for examination and receive symptomatic treatment. Do not use eye drops without authorization. Pay more attention to eye hygiene in daily life, avoid rubbing your eyes with your hands, and prevent bacteria from entering the eyes and worsening the infection.

Wearing contact lenses causes itchy eyes and tearing

After all, contact lenses are foreign substances. When worn on the eyes, they are in direct contact with the cornea. Since each person's adaptability to contact lenses is different due to individual differences, some people will feel itchy eyes and tears when they wear them for the first time. In addition, wearing contact lenses for a long time can cause great damage to the eyes. This is because contact lenses are tightly attached to the cornea, isolating the air and causing eye hypoxia, which can easily lead to inflammation and corneal epithelial detachment, making the eyes very susceptible to infection by germs and bacteria, which can also cause itching and tearing of the eyes.

Countermeasure: Try to reduce the length of time you wear contact lenses, and do not wear them for more than 8 hours a day. It is best to wear frame glasses 2-3 days a week. People who have never worn contact lenses should go to the hospital for an eye examination to see if they are suitable for wearing them. Do not buy contact lenses on your own.

Foreign bodies invading the eyes causing itchy and tearful eyes

If the eyes are invaded by foreign objects, such as dust, pollen, hair in the air, sand blown by the wind, cold air, wind stimulation, eye makeup that has not been removed, etc., they will irritate the eyes, causing the tear glands to secrete excessively, and the tears cannot be discharged from the tear ducts in time and flow out of the eyelids. The bacteria in the foreign objects in the eyes will cause infection, resulting in itchy eyes and tears.

Countermeasures: Blink your eyes as much as possible and shed more tears to allow the foreign body to flow out with the tears. Be careful not to rub it with your hands to avoid aggravating the bacterial infection.

Eye allergies causing itchy and tearful eyes

If your eyes itch and water with obvious seasonality, and are accompanied by allergic symptoms such as itchy nose and sneezing, this is caused by eye allergies. If you come into contact with flowers, dust mites, dust, catkins, animal dander, cosmetics, etc. in your daily life, these will cause eye allergies, and in severe cases, conjunctivitis may occur.

Countermeasures: At this time, you must avoid all allergens, go to the hospital in time to check the main allergens, do not take medicine on your own and delay the disease. You should pay attention to eye hygiene at ordinary times, and do not share towels, washbasins, etc. with family members to avoid cross infection.

Excessive use of eyes causes itchy and tearful eyes

The reason for itchy eyes and tearful eyes is also closely related to excessive use of eyes. This is because of long-term facing the computer, watching TV, reading, etc., which leads to excessive use of eyes and triggers visual fatigue syndrome, resulting in itchy, dry and tearful eyes. In addition, reading, writing, etc. in an environment with too strong or too dark lighting will cause visual fatigue and make the eyes very uncomfortable.

Countermeasures: In life, you must pay attention to eye hygiene habits. After working or studying for 50 minutes, you can use the time when going to the toilet or drinking tea to look into the distance or do eye exercises to relax and rest your eyes to relieve eye discomfort symptoms.
