There are more causes of dry eyes, which need to be treated according to the cause, and there is no fastest way to regulate them. Dry eyes can be categorized into evaporative overpowering type, aqueous deficiency type, mucin deficiency type, tear kinetic abnormality type and so on. 1. Excessive evaporation type: mainly caused by abnormalities in the lipid layer, such as blepharoplasty dysfunction, blepharitis, blepharitis, etc., eyelid defects or abnormalities caused by increased evaporation. Hot compresses can be applied to the eyelids to promote the secretion of grease from the lid glands inside the eyes; wet room glasses can be worn to increase the humidity around the eyes. 2. Aqueous deficiency type: caused by insufficient aqueous tear production, such as dry syndrome, many systemic factors can cause such dry eyes. And these diseases are common in menopausal women, can be improved by oral estrogen drugs, such as estradiol, estradiol benzoate. 3. Mucin deficiency type: caused by damage to the epithelial cells of the ocular surface, including chemical injuries and thermal burns of the ocular surface, and corneal limbal dysfunction such as exposure keratitis. Artificial tears that do not contain preservatives can be used, and topical hormonal eye drops, such as flomilon eye drops, can be used. 4. Abnormal tear dynamics: caused by abnormal tear dynamics, including delayed tear drainage, conjunctival relaxation caused by ocular surface inflammation. Antibiotic ophthalmic ointment can be applied locally to achieve anti-inflammatory and maintain the role of ocular surface moisturization, such as erythromycin ointment. Artificial tears, such as sodium vitrate eye drops, can also be used to keep the ocular surface moist. Medications need to be used under the direction of a physician. When there is dryness of the eyes, you can go to the hospital in time, improve the examination, under the guidance of the doctor to regulate.
