What disease is itchy eyes with a foreign body sensation?

Eyes are very important to everyone, so we must protect our eyes. If you feel any abnormality in your eyes, you must seek medical treatment immediately. There are many reasons for itchy eyes and a foreign body sensation. The most common clinical reason is excessive use of the eyes, which makes the eyes feel particularly dry. At this time, you can close your eyes and rest for a while, or do eye exercises at a fixed time every day, and this symptom can be relieved. Other specific reasons are as follows:

1. Dry eyes

Dry eye syndrome is also known as keratoconjunctivitis sicca. People with dry eye syndrome will experience dry eyes, itchy eyes, a foreign body sensation, pain and burning sensation, sticky secretions, fear of wind, fear of light, and sensitivity to external stimuli; the eyes may even become red, swollen, congested, and keratinized. This is because the stability of the tear film in the eyes is reduced, the tear glands in the eyes secrete insufficient tears, and the eyes are not moisturized.

Countermeasures: Patients with dry eyes should seek timely treatment to alleviate symptoms, because over time it will damage the cornea, cause corneal and conjunctival lesions, and also affect vision.

2. Eye fatigue

It is very common for eyestrain to cause itchy, dry eyes, and foreign body sensation. If you stare at computer, mobile phone and other screens for a long time, or read or write in an environment that is too bright or too dark, it will cause eye fatigue and symptoms of eye discomfort. Especially for people with refractive errors, since they need to use a lot of adjustment power to see far and near, the eyes are overly tired and more likely to suffer from eye fatigue.

Countermeasures: At this time, you should pay attention to eye rest, reduce the time of using eyes, and massage the area around the eye sockets to promote blood circulation in the eyes to relieve eye fatigue.

3. Foreign body invasion

Because the eyes are very sensitive, even small objects entering the eyes may cause eye discomfort symptoms such as itchy, dry, and painful eyes. For example, dust particles, wood chips, sand, eye makeup residues, etc., once they enter the eyes, they will irritate the eyes. The bacteria in these foreign bodies will infect the eyes, resulting in itchy eyes, foreign body sensation, redness, and pain.

Countermeasures: At this time, you should immediately rinse your eyes with clean water, while rotating your eyeballs to allow the water to flush out the foreign matter. If the foreign body is tightly adhered, you should go to the hospital as soon as possible to remove the foreign body.

4. Allergies

If your eyes itch and feel like there is something foreign in them, and there is obvious seasonality, and they are accompanied by allergic symptoms such as itchy nose and sneezing, then it is caused by eye allergies. Allergies are related to contact with allergens, such as contact with flowers, dust, fumes, animal dander, drugs, chemicals, etc., which can cause eye allergies. Especially for people with allergic constitution, when they come into contact with allergens and cause allergic reactions, they are prone to itchy, redness, and foreign body sensation in the eyes.

Countermeasures: First, go to the hospital for a timely check-up to identify the allergens and avoid contact again in the future. During the allergy period, avoid eating "irritating foods" such as shepherd's purse, leeks, mushrooms, squid, seafood, shrimp, fish, etc. to avoid aggravating the allergy.

5. Bacterial infection

Itchy, red eyes with a foreign body sensation are mostly caused by eye infections by bacteria, germs, viruses, etc., which cause certain eye inflammations, such as conjunctivitis, keratitis, iridocyclitis, blepharitis, styes, trachoma, etc. These inflammations can stimulate or compress the nerve fibers of the eye muscles, resulting in itchy eyes with a foreign body sensation, and also accompanied by dry, red, swollen, painful and other discomfort symptoms.

Countermeasures: It is best to go to a regular hospital's ophthalmology department for examination and treatment in time to avoid delay and worsening of the condition. Antibiotic eye ointment or eye drops can be used for treatment under the guidance of a doctor.
