To reduce the risk of eye strain, it is also recommended that you:
● Position the display at a comfortable viewing distance between 20 and 28 inches (50 cm and 70 cm) from your eyes.
● Blink frequently to moisten your eyes, wet your eyes with water, or apply eye drops.
● Look away from your display, and gaze at a distant object at 20 ft (609.60 cm) away for at least 20 seconds during each
break.
● Take an extended break for 20 minutes every two hours.
