There are many reasons for dry eyes, which are often caused by asthenopia and ametropia. If it is caused by ametropia and asthenopia, we should pay attention to rest, reduce close operation, avoid asthenopia, do not stay up late, and correct mydriasis, optometry and glasses. If it is caused by decreased tear secretion or eye lesions, and does not affect vision, sodium hyaluronate eye drops, calf blood deproteinized extract eye drops, and vitamin A palm gel can be used. If it affects your eyesight, you should go to the ophthalmology department for further examination and symptomatic treatment according to the examination. At the same time, attention should also be paid to eye symptoms caused by systemic diseases, such as hypertension, diabetes, blood disease, Sjogren's syndrome, heart disease, kidney disease, etc.
