With the development of science and technology, the application of computers and mobile phones is becoming more and more extensive. First of all, mobile phones, eating, queuing, taking the subway, almost everyone is holding one, in addition to watching dramas, brushing vibrato, chasing novels, from time to time the messages sent from the work group, it is necessary to deal with them in time.
Then there is the computer, the current office, can be without paper and pencil, but can not be without a computer. Like IT, new media, design, etc., many industries are dealing with computers 8 hours a day.
So can I still perform myopia surgery when I use computers and mobile phones regularly?
The answer is: Yes
Most adults have a relatively stable visual condition, after myopia surgery, as long as you master the scientific method of using the eyes, maintaining a clear vision is not a problem.
Let's share with you how to use the computer correctly after surgery
Don't "keep your eyes on" at the computer
Whether it's working, watching a drama or playing a game, every time you use the computer, your eyes will unconsciously reduce the frequency of blinking. But the computer screen is "bright", coupled with the inevitable blue light in the screen light, will aggravate the visual fatigue.
After myopia surgery, it is best not to look at the computer for more than 45 minutes each time, and avoid "keeping your eyes open".
Every 10 seconds or so of staring at the display, you should blink once, and the complete blinking action can reduce the time the eyeball is exposed to the air, avoid tear evaporation, and prevent cornea dryness.
At the same time, after continuous use of the computer for 45 minutes, you need to rest for 5-10 minutes, look at moving objects or green plants 6 meters away, you can also do closed eye rest or eye exercises, but you must pay attention not to rub your eyes to avoid eye bacterial infection.
Angle and distance are important
Distance and angle can reduce the need for refractive light and reduce the chance of eye fatigue. For computer families after myopia surgery, maintaining the correct distance and angle is very important for postoperative care.
Controls the distance between the eyes and the computer screen
Generally, it should be kept at 50 cm - 60 cm, if the screen size is large, you can extend the distance to 70 cm as appropriate. Too close to the eye radiation damage.
The angle of computer placement is also exquisite
It is best to have the top of the screen at the top of the screen 30 degrees down in the horizontal line of sight and the screen tilted slightly up by 10 degrees. The first line of words displayed on the display screen is preferably located about 3cm below the line of sight, so that the eyes form a slight downward angle to gaze at the monitor screen, which can reduce the exposure area of the cornea and reduce the phenomenon of dry eyes.
Portable external device
Small partners who use laptops for a long time to work and play games can configure external mice and keyboards, which are not only more convenient to use, but also adjust the distance between the eyes and the screen to improve the damage caused to the eyes by using the eyes at close range.
The right screen brightness
The computer screen is too dark and too bright is not conducive to the recovery of the eyes after surgery. Too bright can overstep the eyeballs, and too dark a screen can 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 to the fluorescent screen, and the computer should not be used in the dark in the dark, so as not to cause eye fatigue and even cause glaucoma.
The brightness of the computer screen is related to the surrounding environment and the comfort of the eyes, and the brightness of the screen will also be dimmed when the surrounding environment is dimmed.
Generally speaking (for reference only): the brightness is adjusted to about 50 degrees during the day, 30-40 degrees at night, and the contrast is between 70-80 degrees. Ophthalmologists deliberately configure the recommended soft bean paste green (hue: 85. Saturation: 123, brightness: 205) Long-term use can also effectively relieve eye fatigue and protect the eyes.
The right-angle sitting position makes the eyes more comfortable
Maintaining a proper posture is also crucial for the eyes. Do not place the computer obliquely to the side, and do not use the computer sideways, otherwise the adjustment of the eyes will be unbalanced for a long time.
The body and eyes should be placed in the center of the horizontal orientation of the computer screen, and the portrait screen should be slightly overlooked. And keep the head, chest, waist in a straight line, thighs and back form a triangle; elbows have support points. This can protect the eyes very well, avoid causing incorrect eye position and insufficient adjustment of visual function; you can also put the body in a relaxed state when using the computer, reducing the overall fatigue.
It is also particularly important to follow up on time after surgery. On the first day after surgery, the first week, the first month, three months, half a year, and one year, the doctor can grasp the latest eye recovery, help the eye recover better, and if there is discomfort, it can be treated or adjusted in time.
