How do office workers use computers after myopia surgery?

Abstract: too dark and too bright computer screen is not conducive to postoperative eye recovery. Too bright will over stimulate the eyes, and too dark screen will make the eyes look laborious. The contrast between the brightness of the computer and the surrounding light should not be too strong. The indoor lighting light should not be directly reflected on the fluorescent screen. Do not use the computer in the dark at night to avoid eye fatigue and even glaucoma.

due to beauty, convenience and work needs, “myopia white-collar” has launched an upsurge of “mirror removal”. Myopia surgery is a systematic project, not a simple programmed operation. No matter how good myopia surgery is, you still need to cherish your eyes with your own heart. For office workers who have been facing computers for a long time, the correct use of computers is very important for postoperative eye maintenance.

1. Do not stare at the computer

after operation. You will feel sour and astringent in your eyes when you look at the computer for 60 minutes. Experts suggest that you should not stare at the computer for more than 45 minutes every time after myopia surgery. Do not “turn your eyes”.

and

should blink at least once every minute or two when staring at the display. Frequent and complete blinking can reduce the time of eye exposure to the air, avoid tear evaporation and prevent corneal dryness. At the same time, rest for 5-10 minutes after 45 minutes of continuous work. Look at moving objects or green plants 6 meters away. You can also do eye closure rest or eye exercises, but you must pay attention not to rub your eyes to avoid eye bacterial infection.

2. Appropriate angle and distance can effectively reduce dry eye syndrome.

distance and angle can reduce the demand for refraction and reduce the probability of eye fatigue. Many people know these principles, but they may not follow them. For the computer family after myopia surgery, maintaining the correct distance and angle is very important for postoperative nursing.

and

should generally be kept at 50cm-60cm. If the screen size is large, the distance can be extended to 70cm as appropriate. Too close is easy to cause eye radiation damage. At the same time, it is better to place the computer at an angle where the upper end of the screen is located 30 degrees below the horizontal line of sight, and the screen is slightly inclined 10 degrees upward. The first typesetting displayed on the display screen should preferably be located about 3cm below the line of sight, so that the eyes can form an angle to look slightly down at the display screen, which can reduce the exposed area of cornea and reduce dry eye. Place the documents to be read at the same height and distance as the fluorescent screen without moving the focus between two objects too often. For long-term use of notebook computers, additional mouse, keyboard and tilting shelf can be added, so as to browse the screen without fatigue.

3. Appropriate screen brightness will make postoperative eyes more comfortable.

computer screen is too dark and too bright, which is not conducive to postoperative eye recovery. Too bright will over stimulate the eyes, and too dark screen will make the eyes look laborious. The contrast between the brightness of the computer and the surrounding light should not be too strong. The indoor lighting light should not be directly reflected on the fluorescent screen. Do not use the computer in the dark at night to avoid eye fatigue and even glaucoma.

and

suggest that the brightness be adjusted to about 50 degrees during the day, 30-40 degrees at night and 70-80 degrees in contrast. The specific situation also depends on the surrounding environment and eye comfort. Generally, if the surrounding environment becomes dark, the brightness of the screen will also become dark. Ophthalmologists specially configure the recommended soft bean paste green (hue: 85, saturation: 123, brightness: 205). Long term use can also effectively alleviate eye fatigue and protect eyes.

4. Three right angle sitting positions make eyes more comfortable

Keep the most appropriate posture, make your eyes look flat or look down slightly on the fluorescent screen, so as to minimize the area of your eyes exposed to the air. Do not tilt the computer to the side, otherwise the adjustment of both eyes will be unbalanced for a long time. The correct sitting posture of

and

is to “sit like a clock”. Select a special computer desk and computer chair that meet the ergonomic design. When sitting on it, people should maintain “three right angles”: the first right angle is formed at the knee, the second right angle is formed at the thigh and back, and the third right angle is formed at the elbow. The waist and back should be close to the chair back with supporting function, and the arms should sag naturally, Put your elbow on the armrest.
