Computer Vision Syndrome (CVS), also known as digital eye strain, is becoming increasingly common as more and more people spend prolonged periods of time in front of digital screens. This can include not just computers, but also smartphones, tablets, and other devices.
While CVS can affect individuals of all ages, it is particularly common among people who use computers or digital screens for work. It is estimated that, up to 90% of individuals who spend more than three hours per day using a computer or digital screen experience some form of CVS.
There are several factors that can contribute to the development of CVS. Prolonged use of digital screens, poor lighting, improper viewing distances, and incorrect viewing angles are some of the most common causes. Additionally, poor posture and blue light emissions from digital screens can also contribute to the development of CVS.
Symptoms of Computer Vision Syndrome:
The symptoms of CVS can vary from person to person, but some of the most common symptoms include:
Eye Strain: Eye strain is one of the most common symptoms of Computer Vision Syndrome. It is characterized by discomfort or tiredness in the eyes.
Headaches: Headaches are another common symptom of Computer Vision Syndrome. They may be caused by eye strain, poor lighting, or improper viewing angles.
Blurred Vision: Blurred vision is a common symptom of Computer Vision Syndrome, and it can make it difficult to see clearly.
Dry Eyes: Dry eyes are another common symptom of Computer Vision Syndrome. They may be caused by reduced blinking while staring at a screen, which leads to a lack of moisture in the eyes.
Neck and Shoulder Pain: Prolonged computer use can cause neck and shoulder pain, which may be related to poor posture while sitting at a desk.
Difficulty Focusing: Some people may experience difficulty focusing after prolonged computer use. This can make it difficult to shift their focus from the screen to other objects in the room.

Diagnosis of Computer Vision Syndrome:
If you are experiencing symptoms of CVS, it's important to seek medical attention from a qualified eye care professional. At Indra Gandhi Eye Hospital, our team of experienced eye care professionals can perform a comprehensive eye exam to determine the underlying cause of your symptoms.
During your eye exam, your eye care professional will evaluate the following:
Visual acuity: This test measures your ability to see objects at various distances.
Refraction: This test determines whether you need glasses or contact lenses to correct your vision.
Accommodation: This test measures your eye's ability to change focus from near to far.
Binocular vision: This test evaluates how well your eyes work together.
Causes of Computer Vision Syndrome and Prevention:
By following these prevention methods, you can reduce the likelihood of developing Computer Vision Syndrome or alleviate its symptoms if you already have it.
Cause | Prevention |
Prolonged Use of Digital Screens | Take frequent breaks and follow the 20-20-20 rule (look away from the screen every 20 minutes at something 20 feet away for at least 20 seconds). Adjust the brightness and contrast of your screen to reduce eye strain. |
Poor Lighting | Ensure that your workspace is properly lit and avoid glare by using an anti-glare screen or positioning your screen away from direct sunlight. |
Improper Viewing Distance | Maintain a comfortable distance between your eyes and the screen. The ideal viewing distance is about an arm's length away from the screen. |
Incorrect Viewing Angle | Position the screen so that your eyes are level with the top of the screen and avoid tilting your head up or down to see the screen. |
Poor Posture | Sit with your back straight, feet flat on the floor, and arms at a comfortable angle. Use a chair with good lumbar support. |
Blue Light Emissions | Use a blue light filter or wear blue light-blocking glasses to reduce the amount of blue light emitted by your screen. |
