What's going on when my eyes itch?

In people's daily life and work, some factors will cause the occurrence of diseases, especially eye diseases are more difficult to treat. Itchy eyes is a relatively common disease. Many people do not know what causes this disease after they develop this disease. So, what causes itchy eyes?

First, why are your eyes itchy? Don't use eye drops randomly if your eyes are itchy. Itchy eyes are one of the main symptoms complained by ophthalmologists. The judgment of itchy eyes mainly depends on whether there are other symptoms. If there are no accompanying symptoms (no secretions, no photophobia, no conjunctival irritation symptoms, etc.), it is just itchy, and the seasonality of the itching is very obvious, and it is accompanied by nasal allergy symptoms such as itchy nose, clear runny nose, sneezing, etc., it may be caused by allergies. Since patients with allergic conjunctivitis will feel itchy and uncomfortable in their eyes, many patients buy eye drops on their own to treat it, which is very dangerous. Dr. Fei emphasized that there are many reasons for itchy eyes, and if the right treatment is not given, it will cause damage to the eyes. For chronic allergic conjunctivitis, hormonal eye drops and anti-allergic drugs can quickly relieve the symptoms of itchy eyes, but they can only be used in the short term. If hormonal eye drops are used for a long time, it will easily lead to a decrease in eye resistance and an increased chance of infection. It will also cause irreversible damage such as increased intraocular pressure, hormonal glaucoma, hormonal cataracts, and optic nerve atrophy. For acute allergic conjunctivitis, it is recommended to use some hormone eye drops plus anti-allergic drugs for a short period of time as prescribed by the doctor; for chronic allergic conjunctivitis, it is recommended to do a scraping of the conjunctival cells, find out the allergens, and then perform desensitization treatment, which can truly achieve the purpose of "curing the root cause". Another disease that accompanies itchy eyes is dry eye disease. Dry eyes are currently the most common and prominent type of ocular surface diseases, and are also a research hotspot in ophthalmology.

Second, in the past, it was often diagnosed as chronic conjunctivitis. Dry eye syndrome has uncomfortable symptoms such as itchy eyes, dry eyes, and foreign body sensation in the eyes, but the ocular surface is good. Dry eye disease has the main symptoms of dry eyes, incomplete tear film and reduced tear secretion; dry eye syndrome is a type of connective tissue disease and the manifestation of systemic disease in the eye. Dry eyes may be accompanied by symptoms such as dry mouth. With the popularization of computers and televisions, the number of patients with dry eyes is gradually increasing. This is because a normal person blinks an average of 20 times per minute, but when staring at a computer screen, the number of blinks per minute may be reduced to 6-7 times. The main function of blinking is to moisturize the eyeball. As the number of blinks decreases, the degree of moisturization of the eyeball will of course also decrease. For dry eyes, it is recommended to prescribe the right medicine after excluding ocular surface and systemic diseases. You can use some artificial tears, such as Leiran, Beifushu, Aili and other eye drops. If long-term use is required, it is recommended to use preservative-free artificial tears to moisturize the eyeballs and relieve the symptoms of dry eyes.

What is going on when your eyes are itchy? Internet users who often use computers may find that their eyes are always bloodshot, dry, and itchy. This situation is often chronic conjunctivitis and has nothing to do with infection. Therefore, it is not advisable to use antibiotic eye drops. If used, they will not only be ineffective but will also cause drug resistance. In severe cases, they may even cause drug resistance and develop into drug-induced conjunctivitis. Treatment: The cause should be found before treatment, and then corresponding measures should be taken, such as improving the working and living environment, paying attention to personal hygiene, avoiding eye fatigue, ensuring adequate sleep, and it is best for people who work outdoors for a long time to wear goggles, correct refractive errors and strabismus, and actively treat the patient's original eye disease. For those with obvious symptoms such as itchy eyes, zinc sulfate eye drops can be applied 3-4 times a day to relieve the symptoms.
