Today, more and more jobs require us to stare at computer screens for hours. Especially if there are deadlines waiting, we are forced to be in front of the computer all day. Apparently, too long exposure to a computer screen can make your eyes tense.
Eye problems caused by computer use are included in Computer Vision Syndrome (CVS). CVS is not really a special problem, but includes a variety of symptoms of eye strain and discomfort. Research shows that between 50% and 90% of people who work on a computer screen have at least some symptoms.
This syndrome does not only occur in working adults. Children who have a habit of using tablets or computers can also have this problem, especially if their lighting and posture are less than ideal.
How Computers Can Affect Vision?
CVS occurs because the eyes make the same movements repeatedly when working. The longer it is left, these symptoms can get worse.
When working at a computer, the eyes must always be focused at all times. Similar to reading, the eyes will move back and forth. For a moment we might look at the paper and then type again. This makes the eye do the heavy work by reacting to images that keep moving and changing, changing focus, and sending various images quickly to the brain. All of this requires a lot of effort from the eye muscles. And to make matters worse, unlike a book or piece of paper, the screen adds contrast, flickering and glare. What’s more, it’s proven that we blink less when using a computer and can cause eyes to dry out and blur vision.
What are the Symptoms?
There is no evidence that shows the computer can cause long-term damage to the eyes. However, routine computer use can cause eye strain and discomfort. Some of the signs and symptoms include:
- Blurred vision
- Shadow / double vision
- Dry and red eyes
- Eye irritation
- Neck or back pain
How to handle it?
The following slight changes to the workplace can minimize symptoms and prevent new problems, including:
- Reduce lighting
Change the ambient lighting to reduce the effect on the computer screen. If the light from the nearest window is blinding, move the monitor and close the curtains. Buy a table lamp with colors that can be changed to make light evenly on the table. Can also add light filters in front of the monitor.
- Rearrange the workbench
The best position for the monitor is slightly below eye height, which is about 20 to 28 inches from the face. That way, we don’t need to stretch our necks or stretch our eyes to see what’s on the screen. Place a kind of cradle next to the monitor to put printed material that is being worked on so that we don’t have to look at the screen and return to the table when typing.
- Rest your eyes for a moment
Give your eyes a short break by following the 20-20-20 rule. Rest your eyes. Follow the rules 20-20-20. Turn away from the screen every 20 minutes or so and see something about 20 feet away for about 20 seconds. Blink as often as possible to keep your eyes moist. If it starts to feel dry, you can use suitable eye drops.
- Adjust computer settings
Adjust the brightness, contrast, and font size of the computer screen until we find the best settings. Don’t just use factory default settings that don’t necessarily suit our convenience.
- Visit an ophthalmologist if complaints continue and get worse.
Describe the problem you experienced so your doctor can determine whether the use of eyeglasses or contact lenses is needed. Your doctor may recommend the use of special glasses to increase contrast and filter out light entering the eye.
