COMPUTER VISION SYNDROME
70% - 75% of computer users are affected by 'Computer Vision Syndrome' or 'Digital Eyestrain'.
The high visual demands and blue light exposure from increasing use of computers, smartphones, navigation devices and tablets changes our visual behaviour. Our eyes are having to become accustomed to a new range of near vision to accommodate for the shorter distance.
Symptoms include headaches, dizziness, dry/tired eyes, blur/double vision, light sensitivity, eyestrain, neck and shoulder pain.
You can reduce digital eyestrain by following the 20-20-20 rule (every 20 mins of near work, take a 20 sec rest to focus on something at least 20 ft away). Correct the posture and ergonomics (refer to diagram). There are digital protection lenses, which reduces glare and filters the blue light from digital screens and artificial light.
