What is Computer Vision Syndrome?
Dr. Weeraya Pimonrat, an ophthalmologist at Bangkok Hospital, said Computer Vision Syndrome (CVS) is an eye syndrome caused by long-term use of eyesight with computers. The violence will increase with the length of time you use and keep staring at the computer screen. Studies have shown that approximately 90% of people who use a computer continuously for more than 3 hours a day develop one of the symptoms of Computer Vision Syndrome. Or it may be together that it affects the quality of life on a daily basis. The characteristics of the CVS syndrome are as follows: eye pain, dry eyes, burning, irritated eyes, blurred vision, slow focus. Unable to light up eyes, eye sore, headache, or sometimes pain in the back, shoulder, or neck.

Adjust the viewing level between a computer monitor, tablet or smartphone. Optimizing sitting posture for work The center of the computer screen should be 20-28 inches from your eyes, with the keyboard placed below the screen. Keep your wrists and arms parallel to the floor. Elbow perpendicularly Not in the way of reaching forward Adjust chair level The soles of the feet lie flat on the floor, knees perpendicular to the thighs parallel to the floor. Elbow and arm rests may be provided to reduce shoulder, arm and wrist fatigue. Publications or books should be placed at the same level and distance as the screen. So that you do not have to move or turn your head And change the focus too much

But also allows the discovery of eye disease while showing no symptoms Or consultation with an ophthalmologist with expertise and experience Will help us take good care of important eyes And helps to see the world clearly for a long time

This is a problem with many young people. It’s not something that is unique to college students, it is something that affects all of us. We’re always staring at our screens, and it’s really not something we should be doing. This post was originally published here and has been lightly edited for length and clarity.
The idea of staring at the computer for a long time is an old one; in fact, one of the first things I learned on my first day at MIT was how to do it. I didn’t really understand what I was being taught until much later, but it wasn’t hard to figure out why so many people went over to their desk and stared at the screen: because they were bored. https://alvapc.co.uk/product-category/handtools/Hand Tools
Boredom happens when you stare at your computer for a long time, for whatever reason (that might be work, play or studying). You can become so focused on what you are doing that nothing else matters. If you stare for just a few minutes every couple of hours, within a couple of days your brain will start telling you everything else isn’t important anymore — because it doesn’t have anything else to do.
This kind of fixation on the screen is endemic in today’s culture; we spend more time staring than most people even realize — up to two hours per day according to some estimates (and those estimates are based off survey data). But if this isn’t enough distraction in itself, there are all sorts of negative effects as well:
• Staring can make you more sensitive to distractions and less efficient (if you are watching too much TV or reading instead of working)
• Staring can make you more passive (if you just turn off all distractions)
• Staring can make you feel anxious and unable to focus on anything else — which can lead to other kinds of problems like depression, anxiety disorders or addiction (people who stare at their screens report they feel significantly worse when they aren't staring)
Okay - so why do we stare at the computer? In part because many companies think staring at the computer will help them convince someone they need them; but mostly because it keeps our attention focused on what we want instead of what's happening around us (which keeps us focused on what we want).
