Dry eye syndrome is a prevalent disease in middle-aged and elderly people over 50 years old, but with the popularity of computers, some teenagers stay in front of the computer for several hours a day, during which they are highly concentrated and the number of blinks is greatly reduced, easily causing vascular neural regulation disorders and conjunctival congestion. In addition, play computer is also in a dry environment, due to rapid evaporation of water from the eye, coupled with the windows closed air circulation, but also easy to cause eye hypoxia, tear reduction, the ability to flush foreign bodies in the eye is also weakened, which can easily lead to the occurrence of conjunctivitis, suffering from dry eye disease. The prevention of dry eye disease cannot rely solely on eye drops, so is there any way to effectively prevent dry eye disease? Here are four effective ways to prevent dry eye: Yu Guimei, Ophthalmology Department, Siping Central Hospital
(1) Develop the habit of blinking more, to effectively prevent dry eye disease the best way. Professionals believe that dry eye disease is a stress-related condition, and the problem lies in the eyes staring in one direction for a long time. Therefore, the best way to avoid eye strain is to take proper breaks and avoid continuous operation. If you are an eyeglass wearer, it is important to have the right pair of glasses, and for people over 40, it is best to use bifocal lenses or wear glasses with a lower prescription when typing. The posture and distance of work is also very important, try to maintain a distance of 60cm, adjust a most appropriate posture, so that the line of sight can be maintained down about 30 °, such an angle can make the muscle relaxation, and make the surface of the eye exposed to the air to minimize the area.
(2) Long-term computer operators should eat more fresh vegetables and fruits, and increase the intake of vitamins A, B1, C and E. To prevent corneal dryness, dry eyes, vision loss, and even night blindness, computer operators should eat more foods rich in vitamin A, such as soy products, walnuts, green vegetables, cabbage, hollow vegetables, tomatoes and fresh fruits. Vitamin C can effectively inhibit cellular oxidation. Vitamin E is mainly used to lower cholesterol, remove waste from the body and prevent cataracts. Vitamin B1 can nourish the nerves, and green leafy vegetables contain a large amount of vitamin B1. Green tea can be consumed every day because the lipopolysaccharide in tea can improve the hematopoietic function of the body, and tea also has the function of preventing radiation damage. All these foods can effectively prevent dry eyes.
(3) in order to avoid reflections or unclear fluorescent screen, the computer should not be placed on the opposite side or back of the window, the ambient lighting should be soft, if there is a window behind the operator should these foods can effectively prevent dry eye disease. Pull up the curtains to avoid bright light directly onto the screen to reflect the bright image caused by eye fatigue. Typically, the average person blinks less than five times per minute to dry out their eyes. A person working at a computer blinks only one-third as often as usual, thus reducing the production of intraocular lubricants and enzymes. You should blink more often and let your eyes rest at least once every hour.
(4) In order to reduce eye dryness, you can use corneal nutrient solution in the eye, and eye exercises can also relax the regulation of the eye and reduce the effect of visual fatigue. The essence of eye exercises is self-massage, that is, by self-massaging the acupuncture points and skin muscles around the eyes, increase blood circulation in the eye sockets, improve nerve nutrition, can eliminate excessive blood congestion in the brain and the eyeball, due to the smooth circulation, the eye regulation muscle can eliminate the accumulation of metabolites, to eliminate eye fatigue purposes.
To effectively prevent dry eye, experts remind you that when you are fully focused on the computer screen, the number of times you blink will decrease. It is recommended that you blink more often to ensure that the “tear film” can disperse water to the cornea to prevent dry eyes. If you suspect that you have dry eye, do not rely on eye drops as this is only a symptomatic solution, but the right way is to go to the hospital for examination and treatment as soon as possible.
