Electronic Screens at Night

Using Electronic Screens at Night

At night, the distance you are from your screen matters. At 6 inches away, you will get 4 times more light than at 12 inches; and 16 times more than at 24 inches. The further you are away, the better. Double the distance away equals one quarter the brightness intensity absorbed by your eyes. The bigger the screen, the more this matters.

If you must use a computer, tablet or other screen at night:

• Use it for as short a time as possible.
• Be as far away from your screen as you can.
• Adjust the light setting to low- to mid-level brightness.
• Hold the device at least 14 inches from your face.
