Computer Vision Syndrome

Computer Vision Syndrome (CVS), also known as digital eye strain, refers to a group of eye and vision-related problems that result from prolonged use of digital devices such as computers, smartphones, and tablets. The condition is becoming increasingly common due to the growing amount of screen time in daily life.

• Causes: CVS is caused by extended periods of screen use, where the eyes are constantly focusing and refocusing as they process digital images. Poor posture, inadequate lighting, screen glare, and improper viewing distances also contribute to the development of CVS.
• Symptoms: Common symptoms include eye strain, headaches, blurred vision, dry eyes, and neck or shoulder pain. Individuals may also experience difficulty focusing and discomfort after extended screen use. The symptoms typically worsen the longer a person uses a digital device.
• Treatment: CVS can often be managed by making changes to screen habits and ergonomics. Taking regular breaks (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds), adjusting screen brightness, and improving posture can help reduce symptoms. Using lubricating eye drops to relieve dryness and ensuring the screen is at an appropriate distance and angle can also help. Prescription glasses for computer use may be recommended to reduce strain.
