In today’s world, we are looking at screens all the time. For this reason, if we want to keep our eyes healthy, we should be choosy about screens we look. When choosing a monitor to use with a desktop or laptop PC or a gaming console, you should definitely consider its effects on your eyes. You will be staring at this monitor for many hours to work or game. If you have kids, this becomes more important because children are more vulnerable to eye problems like eye strain and eye fatigue. It may seem hard to choose the best monitor for eyes because there are so many technologies, factors, brands and monitors to consider. So, we have prepared this guide to help you on this topic.
Causes of Computer Screen Eye Strain
Eye strain is a symptom occurs when your eyes get tired of intense use such as working at the computer or reading a book for an extended period of time. If you feel discomfort after looking something for a long time, it means you have eye strain. You may feel eye fatigue, pain around the eyes, headache, blurred vision or other symptoms. Eye strain is not an eye disease and it goes away once you rest your eyes. But it definitely affects your daily life and you should prevent your eyes from it.
Eye strain is a part of Computer Vision Syndrome which are eye problems caused by computer use. In these days, there are many people have jobs that require using computers for at least 5-6 hours. Research shows that more than 50% of these people suffer from eye strain. Not just working adults, kids and elderly people also complain about eye strain because tablets, smartphones, and most of the electronic devices have screens. So, what are the causes of eye strain? What should you consider when buying a new monitor for your eyes? Let’s get to the work!
1. BLUE LIGHT
First, what is blue light and why it is bad for your eyes? As humans, we can see red, orange, yellow, green, blue, indigo and violet light. So blue light is one of the visible lights. It has some benefits like boosting alertness, helping memory and elevating mood. It also helps to regulate our sleep/wake cycle. But blue light can also be harmful to your eyes and cause eye strain, eye fatigue, headaches and more. But how does blue light affect our eyes? Let’s find out.
There are several technologies to filter blue light on screens. They have different names but in fact, they all try to do one thing: Filtering blue light. ASUS, BenQ, EZIO and some other monitor brands provide a menu that allows you to choose between different blue light levels for different purposes. Some other monitors come with external filters and there are other solutions like blue light filtering glasses or software named flux.
Advice: If you want to prevent eye strain, you should definitely choose a monitor with a blue light filter.
2. DISPLAY FLICKER AND LOW REFRESH RATE
In these days, most of the screens come with LED backlight. When you use a monitor, LED backlight tries to maintain the brightness of the display. Flicker is caused by this because the backlight rapidly turns on and off to maintain the brightness at the same level. This technology has been used in LED monitors for a long time because it works well. But it can also cause flickering which hurts your eyes especially at low levels of brightness. Flicker cause constant changes in brightness and these changes in light intensity turns into eye strain, headaches, and eye fatigue. It controls brightness but also hurts our eyes. So, what should we do?
Brightness controlling is also named as “dimming”. our new monitor should also have a high refresh rate which is better for your eyes. 120 Hz or 144 Hz monitors are pretty popular these days and if you ever tried 12o Hz or 144 Hz monitors, you will see that these monitors provide a smoother viewing experience. I should also say that a 120 Hz or 144 Hz monitor will definitely improve your gaming working experience. In these days, I would recommend buying a monitor with high refresh rate because they are not so expensive and things look a lot smoother on them. You may watch this video from Linus to get a better understanding of refresh rates on TVs and monitors.
Advice: You should choose a monitor with high refresh rate and a technology which minimizes or eliminates display flickering.
3. Too Low or Too High Screen Resolution
Screen brightness is another important factor you need to consider when choosing the best monitor for eyes. Monitors that are too bright or too dark can cause eye strain and eye fatigue. You should buy a new monitor with automatic brightness adjustment. For example, EZIO uses a new technology named Auto EcoView. This technology automatically adjusts the screen’s brightness to the correct level calculating ambient lighting. Brightness is related to screen flickering and like we said before, it is very important for eye comfort. Too bright or too dark screens can lead to eye strain, headaches, eye fatigue and other discomforts.
Advice: Choose a monitor with adjustable or auto brightness.
4. Bad Posture and Wrong Monitor Placement
When its come to sitting posture, there are a few things you need to consider.
a) You should sit up straight, sit back in the chair and rest your back fully against the backrest of your chair.
b)Your line of sight should be straight ahead or slightly downward because looking straight ahead at the monitor is good for your neck but it can strain your eyes.
c) You should be at least 40-50 centimeters from the screen.
d) Place your feet flat on the floor.
e) Make minor or major adjustments to the angle, height, rotation or orientation of your screen to prevent light reflection.
