If you know the mechanism that causes eye strain, you will also know how to prevent it
Tired eyes, vaguely bright eyes, flickering eyes, bloodshot eyes... If you are in VDT work (work using a display device such as a computer display), you have "eyestrain".
Because it is a physiological fatigue, it will be canceled if work is stopped or time passes. However, if this is left untreated, the shoulders become strangely stiff, headaches occur, and other abnormalities occur in areas other than the eyes. Such a secondary symptom is "asthenopia".
The mechanism is
The eyes, like the rest of the body, have muscles that make them move. However, if you move continuously for a long time, naturally your muscles will get tired and stiff. The energy to move the muscles is also insufficient, and the lactic acid that promotes fatigue increases in the muscles. Continuing to look at a nearby object, such as a monitor screen, causes the ciliary muscle to become tense, causing a kind of muscle pain.
If you think about this mechanism, you will know how to deal with eye strain.
① Rest your eyes
Oxygen is replenished and tense muscles gradually relax. Inactivity also reduces the amount of lactic acid.
② Relax your eyes
You can artificially promote blood circulation and relieve muscle fatigue by massaging around the eyeballs, eye exercises, and acupuncture therapy. ).
③Look far away
The ciliary muscle is tense when looking at a near object, but relaxes when looking at a distant object. It takes 15 to 20 minutes for the tense ciliary body to relax when you are still resting, but you can accelerate the relaxation time by looking into the distance.
As a matter of fact, it is quite difficult to do (3) at work, but try doing it on the rooftop or on the landing of the emergency staircase during your lunch break.
………… How to …………
Decide on a target point several tens of meters ahead, and extend your arm and put your thumb up about 50 centimeters away. If you look at your thumb nail for 1 minute, you will look at a distant target for 2 minutes.
Are you teasing your eyes even though it's the weekend?
Be careful how you spend your weekends.
Weekends are the days when you should get rid of the fatigue accumulated during the weekdays, relax your mind and body, and save energy.
However, more and more people are teasing their eyes on weekends.
(1) Watch the monitor screen for a long time at home.
Operating a computer for fun, watching TV, DVD, and video distribution services for a long time in a darkened room. The worst thing is to bring your computer work home. This is the same as teasing your eyes even though it's a holiday.
(2) Lack of sleep due to preoccupation with play.
On weekdays, I come home exhausted and can't do the things I want to do, such as hobbies. Going style is not good for your eyes. It can be said that whipping for tired eyes and continuing to overuse them for a long time is an act that causes eye strain.
(3) Unreasonable long-distance driving and nighttime driving.
I like cars, but I can't drive on weekdays. Take a holiday there. It's not bad per se, but it's a matter of degree. With a tired body and tired eyes, driving long distances or at night can lead to accidents and strain your eyes.
The unpleasant sensation of "eye fatigue" should be considered as a warning signal indicating that some kind of functional abnormality is occurring in the eye. If you don't change your lifestyle and take some kind of action, it won't improve and it will only get worse. For those who are unable to take the measures introduced here, we recommend using the ultrasonic therapy device "i-power".
