WARNING: The possible long-term effects of
blue light emission from the monitor may cause
personal injury such as digital eye strain, eye
fatigue and damage to the eyes. Using monitor
for extended periods of time may also cause pain
in parts of body such as neck, arm, back and
shoulder.
To reduce the risk of eye strain and neck/arm/back/
shoulder pain from using the monitor for long periods of
time, we suggest you to:
1. Set the distance of the screen between 40 to 197
inches (100 - 500 cm) from your eyes.
2. Blink frequently to moisten your eyes or wet your
eyes with water after prolonged usage of the
monitor.
3. Take regular and frequent breaks for 20 minutes
every two hours.
4. Look away from your monitor and gaze at a distant
object at 20 feet away for at least 20 seconds during
the breaks.
5. Perform stretches to relieve tension in the neck, arm,
back, and shoulders during the breaks.
