The nationwide lockdown due to the COVID-19 crisis has led to an increase in the average screen time of people. People are busy spending a lot of time watching television, and on digital devices like computers, mobiles, and tablets more than ever! Getting hooked to electronic devices for long uninterrupted hours is causing digital eye strain, aka computer vision syndrome in people.
What is computer vision syndrome?
Computer vision syndrome is a temporary eye condition that results from focusing on a digital screen for a long time without breaks. Suffering from CVS does not only affect eyesight but also hampers an individual’s productivity.
Why is computer vision syndrome concerning?
Computer vision syndrome (CVS) affects around 60 million people globally. It has become even more concerning in the times of COVID-19 for well-being for a person. A study shows that nearly half of the population in the world will be short-sighted (myopic) by 2050. One of the primary reasons associated with this eye condition would be the effects of prolonged usage of digital devices or televisions every day.
Symptoms of computer vision syndrome
- Eyestrain
- Blurred vision
- Neck ache
- Headache
- Tiredness
- Insomnia
- Dry eyes
- Shoulder pain
Computer vision syndrome (digital eye strain) causes
There are various causes associated with computer vision syndrome, like:
- Less of blinking
When you are hooked to any electronic devices, you tend to blink less. Less blinking causes dry eyes. Blinking is the natural reflex of eyes to keep it moist. An average person blinks about 16-20 times in a minute. If blinking reduces to 6-8 times in a minute, then gradually, it results in dry eyes and becomes a cause for computer vision syndrome.
- Improper workstation
If you have not set up your workstation in a proper way, then it could cause computer vision syndrome. You need to adjust the monitor, desk, chair, and lighting in the room also so that your eyes don’t feel strained.
- Dry environment and dehydration:
AC’s in offices strip the air of its moisture, thereby making the environment dry. This dryness, an improper workstation, or bad sitting posture, makes people prone to computer vision syndrome.
- Don’t use devices right before going to bed
It will require a bit of planning, but it is important to take a break from the screen at least two hours before you go to bed. Studies show that blue light emitting from screens can affect natural sleep and wake-up cycle.
Ways to deal with computer vision syndrome during COVID-19 pandemic
- Blink often
Remember to blink while watching television or doing work on any digital device. Don’t let your eyes dry out. Be mindful of blinking and keeping your eyes lubricated. Encourage others around you to blink at least 18 times per minute.
- Take frequent breaks
Have you heard of the 20-20-20 rule? While working on a computer or any digital device, take a break every 20 minutes and look at distant objects (at least 20 feet a
