If the product you’re currently using has a glare panel, you can affix low-reflection film to the screen. It’s common for advice to focus on not letting the room be too dark, but if the lights are too bright, it creates a difference between the screen brightness and ambient light, and that’s also no good. More specific details on screen brightness are provided in Point 5. Also pay attention to the temperature setting on your air conditioner and the direction in which it blows.

These things can cause dry eyes, and your seat should never be positioned so that the air conditioner is blowing directly in your face. Next let’s check your posture when you’re looking at your display. The illustration below shows the ideal posture. Generally speaking, the distance between the user and the screen should be at least 40 centimeters or 50 centimeters in the case of a wide screen.

The reason you should be further away from a wide screen is that the wider screen will not fit completely into your field of vision unless you sit further back. The conditions will vary slightly depending on other factors as well, including screen resolution, text size and your eyesight. No matter what the situation, if you are viewing a screen at a distance of less than 30 centimeters for long periods of time, your eyes are obviously going to become fatigued.

If you have an A4-sized sheet of paper, hold it up longways between you and the screen on which this article is displayed and see if there is enough room for it to fit. An A4-sized sheet of paper is about 30 centimeters millimeters long, so if you’re viewing the screen from a shorter distance than this, you’re too close.

If you’re viewing it at a distance of about 1. Once you’re at the proper distance from the display, try to have it so that your line of sight is directly ahead or slightly downward when viewing the screen. You should avoid looking up at the screen, because that can cause dry eye. Your posture sitting in your chair is also important. Sit back in the chair, sit up straight using the back rest, and keep the bottom of your feet completely on the floor.

This eliminates extra strain on your neck, shoulders and lower back. Sitting hunchbacked can lead to health problems in the long run, so you need to exercise caution. If your feet don’t reach the floor, consider using a footrest.

Displays that do not allow sufficient adjustment of the angle and height of the screen can lead users to adjust their posture to the screen position, which prevents them from working in the correct posture. Choose a display that has rich features including a tilt function allowing the screen to be tilted up and down and a height adjustment function. Even if the installation location of the display and your posture during use is proper, working in the same posture for extended periods of time is not good for your eyes.

The reason is that constantly looking at something at a fixed distance causes a gradual decline in your eyes’ ability to focus.

Take a minute break at least once an hour. Look into the distance and move your eyes up, down, left and right to adjust your focus.

It’s also good to regularly use eye drops. A common mistake people make is looking at smartphone and tablet displays during their break. This does not allow your eyes to rest. Stretch to relieve tension, stand up and walk around, and look near and far either indoors or outdoors to adjust the focus of your eyes. If you find yourself forgetting to take breaks, a smart trick is to use a PC software timer or your smartphone’s timer to remind yourself. There are also some displays that come with a function that prompts you to take breaks.

The suggestions up to this point have been predicated on the assumption that you have sufficient eyesight or that you use glasses or contact lens to properly correct your eyesight. Eyesight changes gradually during daily life activities. Even if you wear glasses or contact lenses, if you stay at the same prescription for many years, your eyesight will change without you realizing it, and this could cause eye fatigue or migraine headaches.

Using eye drops and adjusting the focus of your eyes during breaks does not help this problem. Where you get in trouble is your eyesight doesn’t change suddenly one day, so even if you have symptoms like eye fatigue and headaches, it’s hard to identify the cause.

If you let it go, it could lead to glaucoma and other worsening symptoms, so you should have your eyes checked at least once a year, which may be included in your company or school health examinations.

Be vigilant about checking to make sure your prescription is not off. The brightness of your display should not be left at the default setting but adjusted according to the brightness of the room where it’s installed.

This can greatly reduce the strain on your eyes. But when you give specific numbers like this, most people have no idea what they mean. So what you want to remember is that the trick to adjusting the brightness is using white paper like copy paper. Compare the paper under the lighting in the room to the screen, and adjust the brightness of the display so that the brightness matches as closely as possible.

This will put the brightness at about the right level. Particularly, when using the display for work, you’ll often be comparing paper documents with documents on the screen, so by adjusting the brightness of the screen to the brightness of the paper under the lighting, you’ll reduce the strain on your eyes, making this an effective measure against eye fatigue.

What you need to remember is that if the brightness of the room where the display is installed changes dramatically in the morning, afternoon and evening, the brightness of the screen needs to be changed accordingly, or there’s no point.

If you have to adjust it frequently like that, doing it manually is bothersome, and keeping it up becomes difficult. Consider purchasing a display that comes with a function to automatically adjust screen brightness to the optimal setting according to external light. In some cases, the brightness adjustment mechanism dimming system causes eye fatigue. Specifically, caution is required with the system called PWM Pulse Modulation , which is employed by most displays.

In this system, the LED element blinking time is adjusted to control the display brightness — extending the time that it’s on makes it brighter, and extending the time that it’s off makes it darker. For some people, this blinking of the screen is experienced as flickering, leading to eye fatigue. There is a difference among individuals in how this flickering is experienced. Many people using the same display will not notice anything at all, so even in an office where the same model is purchased in bulk, it’s difficult to figure out that the display is the cause.

The only way to prevent this is to address it with the display itself. Some displays prevent flickering by employing special dimming systems such as DC Direct Current , a system that, in principle, does not produce flickering, and EyeCare Dimming, a hybrid system used in some EIZO products.

By purchasing a product like this, you may eliminate eye fatigue for which the cause was unknown. We’d like to add a note about the EyeCare dimming system. This hybrid system uses DC dimming at high brightness settings and PWM dimming at low brightness settings as it does a better job than DC dimming at reproducing colors at low brightness.

PWM dimming is only used at low brightness settings, so the blinking luminance difference is smaller, thereby controlling flickering. If you feel like your eye fatigue has worsened since starting to use your current display, this could be the cause.

If you’re in an office, switching out displays with another member of the staff is another effective way to identify the cause. We put a small USB fan in front of the screen to check for flickering. At high brightness, DC dimming is used, and the light emitting elements do not blink, so the shape of the blades appears circular left. At low brightness, PWM dimming is used, and the blades appear separate from each other, so you can see that high-speed blinking that can’t be perceived is taking place right.

Recently, it has become common to hear blue light pointed out as a cause of eye fatigue. This refers to light that is visible to humans visible light with a wavelength close to that of ultraviolet rays.

Because it has a high level of energy, it is generally said to place a strain on the eyes. The reason it has recently been the subject of attention is that there are many LCD products with LED backlights that have a high color temperature display white appears bluish , and there are more cases where the user is subjected to stronger blue light than with conventional displays, so this type of problem has come under closer scrutiny. Some methods to address the problem are to wear blue light blocking glasses or to apply blue light reducing film to the LCD screen.

Also remember that on products that allow the display picture quality to be adjusted, you can lower the color temperature on the display. However, lowering the color temperature causes the screen display to change to reddish or yellowish in color, and color reproducibility is lowered.

For that reason, it’s best if you can lower the color temperature for working with office documents and put it back to normal when doing creative work dealing with photographs and images. Some display products come with a blue light suppression mode. Not only do they allow you to easily switch between modes, but in some cases there is software for automatically changing the display mode according to the application, practically eliminating the need to switch modes manually.

It’s a little painful to hear, but in many cases, changing your lifestyle habits is a fundamental way that you can address eye fatigue. If you have poor lifestyle habits that can bring about poor physical health like lack of sleep, lack of exercise or nutritional deficiency from poor eating habits, take this opportunity to re-examine them.

Cutting down on PC and smartphone use before bedtime is also a surprisingly important point. The light put off by PC and smartphone screens, including the aforementioned blue light, is said to be effective in waking you up. Looking at these screens before bedtime tends to make it harder to fall asleep. Considering this, it’s actually not a good idea to read e-books on smartphones or tablets before bedtime.

You may need to disable this in order for the computer to wake up faster. Graphics Card — If you have a high-end graphics card installed, make sure you have the latest driver and management software installed. If you go through the settings, you may find an option that puts your graphics card into lower power mode or something similar. Monitor — Lastly, some monitors have power saving features themselves.
