Arm-Screen Test

From the Web

How you sit in front of your computer can make a huge difference to your health and appearance.

Helen Foster in Australia’s ‘Good Health’ April 2014 issue reports:

Sagging in the lower half of the face is a coming sign of ageing but, according to plastic surgeon Dr. Michael Prager, poorly set-up computers trigger it to occur earlier than it should. He theorises that looking down at a screen causes the neck muscles to shorten, pulling the face down. If you spend your day in front of a screen, then you need to do the arm-screen test.

“Your monitor should be one arm‘s length away from your eyes,” says Dr. Michael Egan, from Sydney ergonomic specialists Elevate. “Reach your arm out, at shoulder height. You should be able to touch the screen without rounding forward.” If you can’t move it closer. Then, once the screen is at the right distance, you should be able to see it without squinting (a major cause of furrowed brows).

Computer Screen

If you can’t, increase the zoom factor of your browser (Ctr+minus or plus) or of your document (looking glass), which is better than increasing the font size as you might want to share that document. A study by IBM found this reduced the length of time people fixed their gaze on individual letters, thereby reducing the risk of squinting and eye strain.
