Computer Vision Syndrome (CVS), also known as Digital Eye Strain, refers to a group of symptoms that occur due to prolonged or excessive use of digital devices, such as computers, smartphones, and tablets. It is a common condition in the modern era, affecting people of all ages who spend significant time in front of screens.Symptoms of Computer Vision Syndrome
- Dryness, redness, itching, or burning sensation in the eyes
- Difficulty focusing, experiencing hazy or double vision.
- Tiredness or heaviness in the eyes, especially after prolonged screen use.

- Muscular discomfort due to poor posture while using digital devices.
Causes of Computer Vision Syndrome
The causes of Computer Vision Syndrome are multifactorial. They include:- Extended periods of staring at digital screens, such as computers, smartphones, and tablets, can strain the eyes and lead to CVS.
- High-energy blue light emitted by screens can contribute to eye fatigue and discomfort.
- Insufficient or excessive lighting in the environment can strain the eyes, exacerbating CVS symptoms.
- Incorrect monitor position, improper viewing distance, or glare on the screen can contribute to CVS.
Diagnosing Computer Vision Syndrome
Diagnosing CVS involves an eye examination by an optometrist. Evaluations typically typically includes:- Discussion of symptoms experienced during or after screen use.
- Assessing the clarity of vision at various distances.
- Determining any refractive errors that may contribute to CVS symptoms.
- Examination of the overall eye health and any underlying conditions.

- Ensure adequate lighting in the environment, minimizing glare and adjusting room lighting as needed.
- Take regular breaks from screen use, practising the 20-20-20 rule (look away from the screen every 20 minutes at an object 20 feet away for 20 seconds).
- Maintain proper posture, position the screen at eye level, and use an ergonomic chair and desk setup.
- Remind yourself to blink regularly and perform eye exercises to reduce eye strain.
