How Do Computers Affect Our Vision?
Computer Vision Syndrome can be likened to carpal tunnel syndrome for the eyes. Repetitive motions can cause injury over extended periods of time. This happens because your eyes are forced to continuously perform the same set of actions over and over. The longer a person persists with the same set of actions, the more likely for the injury due to repetitive motion is to worsen.
When using a computer, your eyes have to repeatedly focus on different parts of the screen. Back and forth movements are repeated as you read or study different portions of the screen, or interact with the notes and tools placed nearby your workstation. To properly focus and send the appropriate signals to your brain requires substantial effort from the eye muscles that control the eye. To make things worse, we tend to blink less frequently when our attention is directed on the computer screen. This leads to the eyes drying out, causing blurry vision.
For those with pre-existing eye conditions, remember to control and manage the use of computers and other digital surfaces. They are far more likely to develop computer vision syndrome, especially if they do not manage their current conditions well. For example, if you are myopic but frequently go without wearing your glasses, this can cause strain on the eye during extended periods of computer use and increase the likelihood of developing computer vision syndrome.
As we age, the natural lenses in our eyes lose flexibility. You’ll notice that many people will start complaining of bad vision as their eyes start of lose the ability to focus on near and far objects. Eye specialists refer to this condition as presbyopia.
