Dry eyes and lack of water are mostly considered to be caused by dry eye syndrome, which can be relieved by general treatment or medication, and serious cases can be treated by surgery. 1. General treatment: Steam eye mask or hot towel can be used on the skin of the eyes to increase local blood circulation and relieve the symptoms of dry eyes. 2. Medication: The use of artificial tears to keep the eye surface moist and relieve dry eye symptoms is one of the main treatment measures at present. Patients who need to use artificial tears for a long period of time should choose preservative-free dosage form, so as not to aggravate the damage to the eye surface and tear film. If dry eye is combined with more serious inflammation, anti-inflammatory drugs are also needed, such as cyclosporine A eye drops. 3. Surgery: For those with normal submandibular gland function, autologous submandibular gland transplantation can be chosen to solve the problem of tear secretion in dry eye patients. Severe dry eye patients may also consider permanent lacrimal punctum closure surgery to reduce or prevent tear drainage through the lacrimal duct, thus keeping the eyes moist. All of these medications should be used under the supervision of a medical professional. Dry and dehydrated eyes are also associated with poor eye habits, daily life should avoid prolonged use of the eyes, timely relaxation of the eyes. If the symptoms are serious, it is recommended to consult a doctor for professional treatment.
