Using a Computer: 3 Signs Your Eyes Are Strained

Posted on: 20 August 2019

If you have a job which requires you to spend long hours looking at a computer screen, you may be at risk of developing eye strain. Understanding the signs that your screen time is placing strain on your eyes can allow you to take action to remedy the situation. Read on to find out more about the signs of eye strain caused by a computer screen.

Your vision becomes blurred

If you find it difficult to focus on text or images on the screen, your eyes may be suffering from strain. Your vision becomes blurred because the muscles inside the eye that control the lens that focuses light onto the retina become tired. When this muscle is tired, the lens isn't able to properly focus, and as a result, what you see will appear slightly blurred. Once you step away from the computer, your vision should return to normal. Taking regular breaks can help to reduce the likelihood you will experience this problem.

Your eyes feel sore or tired

If your eyes feel sore or tired after you have been using a computer for an extended period of time, this could be a sign that they are strained. Straining occurs when you have to focus on and scan a large volume of text or when you need to concentrate on one particular aspect of the screen, such as when designing digital graphics. This repetitive movement and intense focus can cause the muscles that surround your eyes to become inflamed and tired. Looking away from your screen now and again for a minute or two and taking a longer break every so often can help to reduce the chance of this problem occurring.

Your eyes are dry

When you are focused on a screen for a long period, the rate at which you blink may be reduced. The purpose of blinking is to keep the surface of the eye lubricated and to remove any dust or debris that may have become trapped on the surface. Reduced levels of blinking can cause your eyes to dry out. If dust or debris becomes stuck to the surface of your eye, this can create a lot of discomfort. Using eye drops can help to reduce the chance you will experience this issue.
