Many people spend most of their time staring at computer screens, but this negatively affects their eyesight.

As you read, you would understand how using a computer affects your eye health and vision and ways to minimize the damage.

Computer Vision Syndrome

Many people experience symptoms like eye strain, redness, blurry vision, or headaches after staring at a screen for a long time. This is due to the effect of extended computer use, commonly called computer vision syndrome (CVS).

With over 70 million people using computers worldwide, computer vision syndrome has become an occupational hazard of this internet age.

The computer’s effect on our vision is due to the way we view screens. Most people think that reading a paper document and browsing on a computer or tablet is similar, but the eyes see them differently.

Printed characters are easy on the eyes, but screens have a good contrast level and high definition. If the resolution is lower, characters on screens appear bright in the center but blurred on the edges of the screen.

While viewing characters on a computer, the eyes need to adjust several times to focus on the characters properly. This causes eye strain, especially if you don’t take regular screen breaks to rest your eyes.

Steps to reduce eye damage

The ideal solution for strained eyes is drastically cutting down on screen time. However, this is not practical for many people since they work with computers.

Several practical steps are available to help reduce the effect of using computers on the eyes and vision. These steps include the following.

  1. Regular screen breaks

You can try setting the alarm every 20 minutes to take breaks and rest your eyes. During the break, walk across the room to also help correct your posture.

  1. Good lighting

Staring at a screen exposes your eyes to screen glare, but its effect is reduced with good lighting. You can adjust your computer contrast setting to feel comfortable on your eyes.

Removing other objects like the desk lights and keeping your screen in a good position, so it is not in front or behind a window can also help reduce glare

  1. Screen distance

Being too close to your computer while using it is also an issue. The perfect distance between a screen and your eyes is 60 – 70cm. You also need to look down at your screen to allow the center of the screen to be lower at about 20 degrees.

  1. Eye test

If you have an eye or vision problem such as hypermetropia or myopia, the effect of computer use will be worse on your eyes.

However, getting regular eye tests can identify any eye problem, and you can get the right prescription for it.

  1. Computer glasses

Computer glasses are specially designed spectacles that reduce the effect of using a computer on your vision and eye health.

The computer glasses help you focus on a screen without eye strain, so the prescription of your computer glasses may differ from your reading glasses because the focus on objects is at a different distance. These glasses have a reflective coating and are tinted to reduce glare.

In a Nutshell

Sitting in front of a computer screen can be hazardous to health, however, with few precautions, the damages can be reduced to quite an extent. Try these precautions if you have to use your Computer frequently.
