Are You Suffering from Computer Vision Syndrome?
In today’s modern work environment, an average person is spending close to 8-9 hours looking at a computer screen. This doesn’t even account for all those hours spent looking at your mobile phone or a TV screen. This seemingly harmless screen usage can unfortunately lead to a host of problems, primarily among which is CVS or Computer Vision Syndrome. If you aren’t sure if you have CVS, check if you face the following symptoms:
- Hazy or Double Vision
- Dry Eyes
- Irritation in the eyes
- Irritation in the eyes
- Neck or Back Aches
While not life threatening or anything, CVS, if left unchecked, can lead to much severe eye problems. There’s no need to particularly cut down on screen time, although you should ideally attempt to reduce frivolous screen time. But you should ideally take small computer breaks between hours of usage. This can be as simple as taking your eyes of for a few minutes to as complicated as using portable eye relaxing machines.
Taking precautions while using a computer screen is also a good idea. Take note of things like the distance of your face from the screen, your posture, the lighting of the room, etc. And perhaps one of the most important things to consider if your job involves continuous computer usage, is to schedule regular and thorough checkups with the ophthalmologist.

What is Computer Vision Syndrome?
Computer Vision Syndrome is a group of eye and vision-related problems that result from prolonged use of digital screens such as computers, tablets, e-readers, and smartphones. It’s a condition affecting people of all ages, especially those who work long hours in front of a computer or frequently use mobile devices.
Common Symptoms of CVS
If you’re experiencing any of the following symptoms, you may be suffering from Computer Vision Syndrome:
- Eye strain or discomfort
- Dry or watery eyes
- Blurred or double vision
- Headaches
- Neck, shoulder, or back pain
- Increased sensitivity to light
- Difficulty concentrating
These symptoms often worsen after extended screen use and may improve with rest, only to return the next day.
What Causes CVS?
Several factors contribute to CVS, including:
- Poor lighting or screen glare
- Improper viewing distances
- Uncorrected vision problems
- Inadequate posture during screen use
- Lack of blinking, leading to dry eyes
- Extended focus on screens without breaks
How to Prevent or Reduce CVS?
The good news is that Computer Vision Syndrome is preventable and manageable with a few lifestyle adjustments:
- Follow the 20-20-20 Rule: Every 20 minutes, take a 20-second break and look at something 20 feet away.
- Adjust Screen Settings: Reduce screen brightness, increase text size, and use blue light filters.
- Use Proper Lighting: Avoid glare and position your screen to reduce reflections.
- Maintain Good Posture: Sit upright with your screen at eye level and keep your feet flat on the ground.
- Blink Often: Make a conscious effort to blink regularly to keep your eyes moist.
- Schedule Regular Eye Exams: Visit an eye care professional to detect and correct any vision issues.
There have been many latest advances in medical science that is going to make your lives much easier. Advances in IOL or Intraocular Lenses Link to have led us to tri-focal lenses that can manage three focal points at once. These are proven to be extremely helpful with CVS. But they are still a few years away from mass deployment. Until then, take precautions, rest your eyes, and make regular visits to your ophthalmologist.
