What is
Digital Eye Strain?

Digital eye strain, also known as computer vision syndrome, refers to a group of eye and vision-related problems that result from prolonged use of digital devices such as computers, smartphones, tablets, and e-readers.

Risk Factors


Vision may become temporarily blurred during or after prolonged screen use, making it difficult to see text and details clearly.

A feeling of discomfort or fatigue in the eyes is a hallmark symptom of computer vision problems. It can range from mild to severe.

Dryness and irritation of the eyes can occur due to reduced blinking when staring at screens, leading to insufficient moisture on the eye’s surface.

Some individuals may experience double vision or ghosting of text and images on the screen.

Reading on a screen may become challenging, with text appearing less clear and harder to decipher.

Increased sensitivity to light, especially glare from screens or overhead lighting, can be bothersome.

Tension headaches or frontal headaches are common symptoms of computer vision problems and may be accompanied by neck or shoulder pain.

These symptoms are usually temporary and can be alleviated by taking breaks, practicing good ergonomics, adjusting screen settings, and following the 20-20-20 rule (taking a 20-second break to look at something 20 feet away every 20 minutes of screen use).

Treatment Types

Vision Correction

An accurate prescription for eyeglasses or contact lenses specifically designed for computer work can help reduce eye strain and improve visual clarity during screen time.

If dry eyes are a symptom of your computer vision syndrome, artificial tears or other dry eye treatments can provide relief from discomfort and improve tear film stability.

Specialized lenses with blue light filters can reduce the amount of high-energy blue light emitted by digital devices, minimizing eye fatigue and discomfort.

Practicing good visual hygiene, such as reducing screen time, adjusting display settings, using proper lighting, and maintaining a healthy overall lifestyle, can significantly alleviate symptoms of CVS.

Maintain proper ergonomics by ensuring your computer monitor is at eye level and positioned about 20 inches away from your eyes. Use an ergonomic chair and keyboard.

Consider getting eyeglasses with AR coating, which can reduce glare and reflections from screens.

These are just a few examples of the treatments used to address Digital Eye Strain. The field of Digital vision is continuously evolving, and researchers are constantly developing new algorithms and techniques to improve the accuracy and efficiency of computer vision systems.

Frequently Asked Questions

What is Digital Eye Strain?

Digital Eye Strain, or CVS, refers to a group of eye and vision-related problems resulting from prolonged computer, tablet, e-reader, or smartphone use.

Common symptoms include eye strain, blurred vision, dry eyes, headaches, neck or shoulder pain, and sensitivity to light.

Anyone who uses digital screens for extended periods is at risk, but those who spend hours on computers for work or leisure are more susceptible.

Blue light-blocking glasses can reduce exposure to harmful blue light emitted by screens, potentially reducing eye strain and improving sleep patterns.

If symptoms persist or worsen, it’s advisable to consult with an eye care specialist for a comprehensive eye examination to rule out underlying eye conditions and receive personalized recommendations.

Computer glasses may have specific coatings to reduce glare and filter blue light, making them more suitable for extended screen use. Regular eyeglasses correct vision but may not have these features.
