What is Computer Vision Syndrome?

Computer vision syndrome is a group of eye- and vision-related problems that may be caused by a number of factors such as the lighting in the room, distance from the screen, glare produced by the screen of digital devices, seating posture, and the angle of your head. One or any combination of these factors may result in an uncomfortable amount of strain on your eyes.

According to eye specialists in a webinar organized by the Associated Chambers of Commerce and Industry of India (ASSOCHAM), CVS is a new type of disease that emerges due to more people spending long hours in front of computer screens. 

According to Dr. G.V. Divakar, Managing Director, Divakar's Speciality Hospital, the use of electronic devices such as phones and laptops has increased by 75 percent since the pandemic started.

Symptoms of CVS

Around 50-90% of people who spend time in front of the computer screen may experience CVS symptoms, it is important to know that computer vision syndrome (CVS) isn't one specific problem, but rather a whole range of eye problems.

When you spend hours looking at a screen, it reduces the blinking rate of the eyes causing it to dry and may blur your vision periodically while working. Concentrating while working can also put a strain on your eye muscles, not to mention the screen's contrast, flicker and glare can also add up to the discomfort it causes your eyes. 

How to Minimize CVS Occurrence

Dr. G.V. Divakar suggested that screen time should be reduced as well as the resolution of the screen to avoid developing CVS. Aside from that, eye drops can also be used as supplements. 

The maximum screen time should be 30-35 minutes at a stretch and to practice the 20-20-20 rule to avoid CVS consequences.

People should take a break every 20 minutes for about 20 seconds and look at something 20 feet away. This can help relieve eye muscles and relax and enhance blood circulation to the eyes, neck, and back.

Make sure that your work in a room where the lighting is comfortable to your eyes and your head is in a naturally comfortable position while using the computer. Invest in a chair that provides ergonomic support to your neck and back to avoid  neck and shoulder strain which are commonly associated with computer vision syndrome.

Even with the ongoing pandemic, people should still have their regular eye checkups to make sure their eye is in good health.
