Hello: Dry eye is a type of disease in which the tear film is unstable and the eye surface is damaged due to abnormalities in the quantity or quality of tears, resulting in eye discomfort symptoms. Dry eye can be divided into two main categories: insufficient tear secretion and dry eye with normal tear gland secretion function. The latter is due to excessive tear drainage, or evaporative dry eye. The treatment of dry eye is generally symptomatic, and discovering the cause of dry eye and treating the cause is definitely the key to dry eye treatment. In addition, you should pay attention to your eye habits and take regular breaks, such as not spending too much time in front of the computer screen, and take a break for 5-10 minutes every hour, and try to relax your eyes by looking into the distance when you have a gap. The eyes look inward and downward, so when resting, try to let the eyes look to the upper left and upper right. Pay attention to the dietary structure, take more vitamins A, C and D, and eat more carrots, fruits and seafood. Sun Kang, Ophthalmology Department, Foshan Chancheng District Central Hospital
