Watching electricity and eye Stress

Close your eyes, turn your head, relax your stiff neck, and bend your back and sit a few inches away from the computer screen, ignoring the blurred vision that appears repeatedly, even if you cannot see the words on the monitor. at this time, you need to note: every time you press the keyboard, watch a video, and send an email, is it compromising your eyesight?

Myopia means that only things less than 40 cm of the eyes can be clearly imaged on the retina.

Even though the display is usually around 50 cm away, ophthalmologists, optometry, and other eye practitioners see connections between computer screens and myopia.
System, but only a small number of people with close eye use to deepen myopia. it is still unclear whether myopia is due to reading books or staring at computer screens. james, Department of ophthalmology, Pacific University, Oregon
James Sheedy said: "We have not yet determined what is working ."

Although not everyone will be short-sighted due to close eye use, it does not mean
Close to the computer screen is okay. Although most of the time close-up operations on the computer do not cause permanent damage, they do cause discomfort, impaired vision, and other eye fatigue symptoms. Professor of ophthalmology at Ohio State University

Bullimore) said: "eye fatigue is produced by staring at the computer screen for a long time. These continuous eye activity gradually exhausted the eyes: Eventually manifested as fever, dryness, muscle pain, and a series of discomfort.
Symptom ."

The best way to understand and prevent eye fatigue is to study how the eyes see small fonts. When we "see" something, we actually see the light reflected by the object. The light passes through
The cornea (transparent dome-shaped film covering the eyes) and the lens (a flexible circular transparent structure behind the iris) are refraction bent and projected onto the sensor. A sensor is a rod-shaped image that collects light information on the retina.
Cell and cone cell are the innermost layers of the eyes. They are responsible for collecting and transmitting incoming light information and reaching the brain through visual nerves to form images.

The role of the mascara muscle is to change the shape of the lens to make the eyes
Focus more accurately. staring close to the computer screen will make the mascara muscle tight, continue to contract but not relax, causing great damage to this poor little muscle. the close focus will also stop blinking. siyi believes that blinking
It is very necessary because it causes tear to cover the eyes and wet the cornea. if you stop blinking, the cornea surface will be dry and become "frosted glass" to blur the line of sight. when using a computer, the blinking frequency ranges from 1 minute
It has been reduced to around 20 times a minute and 7 times a week, although experts believe this will not have a long-term impact. Dennis Roberts (Dennis
* Staring at the display may also cause strabismus if there is a dazzling glare around it, said Roberts. although strabismus can avoid glare and prevent excessive light from hitting your eyes (this reduces the number of blinking bands
But it keeps the mascara around the eyes in a tight state, and makes the eye stand out for a whole day, as tired as 9 hours of sit-up.

Eye fatigue often persists
For a short period of time, as long as we blinks or look at the distance, it will disappear, but as soon as it appears, it will hinder our work, it will also make us upset. even so, when we feel eye fever, pain, and dryness
Can be adjusted by improving the working environment. to reduce the contrast, you can configure an eye protection screen to eliminate glare at the moment (do not be afraid to reduce the brightness of your computer. similarly
Place the display screen under your sight so that the top of the screen is on the same horizontal line as your eyebrows. seeing a doctor with a pair of glasses to correct your eyesight is a necessary means to protect your eyesight. finally, exclude all the glare
And messy light. to find out what light is causing trouble, Siyi recommends a trick: using both hands as the teeth, tongue, and hat to hide your eyes and see if it relieves tension on your face and shoulders. if
If the "Hand masking" method is effective, you can hide the light that you think is causing trouble. experts advise you to keep yourself at a proper distance from your favorite siteconnoisseurs when you watch TV.
First ).

However, until now, the simplest and best professional advice for all media to eliminate eye fatigue is still regular rest. even if you are not thirsty, you have to go to the water dispenser and make sure that you have to keep your TV chair at least 2 feet (about 0.6 meters) away ). the most important thing is not to forget to blink.
