The 21st century has witnessed a remarkable technological revolution that has transformed the way we work, communicate, and entertain ourselves.

This has led to more and more people to spend most of the day using their intermediate and near vision. While these advancements have brought numerous benefits, they have also introduced a set of challenges, with Computer vision syndrome (CVS) being one of them.

A study cited in the National Library of Medicine showed that approximately 90% of computer users, who spend more than 3hours per day in front of the computer screen, suffer from CVS

Computer Vision Syndrome

What is Computer vision syndrome (CVS)?

Computer Vision Syndrome (CVS), also known as Digital Eye Strain, is a modern-day concern that has gained significant attention due to the widespread use of digital devices. The proliferation of smartphones, tablets, laptops, and desktop computers has led to a significant increase in the amount of time people spend staring at screens. This phenomenon has given rise to a range of visual and physical discomforts collectively referred to as Computer Vision Syndrome. This syndrome encompasses a variety of symptoms that can negatively impact a person's visual comfort and overall well-being.

Some of the common symptoms of Computer Vision Syndrome include:

1. Digital Eye Strain: Prolonged screen time can cause the eye muscles to become fatigued, leading to discomfort, pain, and a sensation of eye strain.

2. Dry Eyes: Staring at screens can reduce the frequency of blinking, leading to dry and irritated eyes.

3. Headaches: Extended screen exposure can contribute to tension headaches and migraines, often originating from eye strain.

4. Blurred Vision: Prolonged screen usage can cause temporary blurriness or difficulty focusing on distant objects after prolonged close-up screen viewing.

5. Neck and Shoulder Pain: Poor posture while using digital devices can result in neck and shoulder discomfort.

6. Sleep Disruption: Blue light can interfere with the body's production of melatonin, a hormone that regulates sleep, so too much exposure to this in the evening can potentially lead to sleep disturbances.
