According to a survey conducted by the National Institute for Occupational Health and Safety, 90% of people who work in front of a computer for more than 3 hours a day will have eye problems, showing a variety of symptoms, including dry eyes, redness, headaches, eye swelling, eye discomfort, blurred vision, fluctuating vision, unnamable discomfort, intolerance of smoke, ash and dirty air, and even irritability and difficulty concentrating. This computer vision syndrome is typical of dry eye disease. It has also been found that the average video game fan does not blink once in more than 2 minutes, while the average person blinks once in 5 seconds. As a result of long hours of looking at the computer screen, the number of blinks decreases, and the evaporation of tears is too strong to cause all the above discomfort. With the development of society, video products are everywhere in people’s lives. As a result, the incidence of video terminal syndrome (VDT) in the population is increasing. Almost more than half of the patients visit the hospital due to dry eye and visual fatigue. These patients have pathological damage on the surface of the eye, that is, the white and black parts of the eye that we see, which is professionally known as corneal and conjunctival degeneration, forming dry eye. If left unchecked, it not only affects the patient’s visual function and quality of life, but may also have serious consequences. In the early stage, it often manifests as a long-standing conjunctivitis, and when it progresses, changes such as congestion, yellowing, thickening and lack of luster in the white part of the eye are noticed, causing vision loss in severe cases.
