Computer Vision Syndrome: Symptoms, Causes and Simple Remedies
Looking at computers and phones for a long time can make your eyes feel tired or uncomfortable.
This problem is called Computer Vision Syndrome or digital eye strain.
Your eyes may become dry, red, watery or blurry.
You might also get headaches or have trouble focusing.
Staring at screens can make you blink less.
Brightness, glare, small text and poor posture can make the discomfort worse.
Every 20 minutes, look at something about 20 feet away for 20 seconds.
Keep screens at a comfortable distance, reduce glare and take regular breaks.
See a healthcare professional if symptoms continue or get worse.
Computer Vision Syndrome, or digital eye strain, can follow prolonged use of digital screens.

Reduced blinking, glare, poor posture and unsuitable screen settings are common contributors.
The 20-20-20 rule recommends looking about 20 feet away for 20 seconds every 20 minutes.
