Computer Eye Strain Harms Academic Performance

Yesterday I saw an article by Meg Nugent of Newhouse News Service in the local newspaper about .

Computer [tag-tec]eye strain[tag-tec] caused by low quality monitors, too much time spent in front of a computer monitor, or poor ergonomic setup, with reflection glare, etc.

The picture coming with the article shows a 4 or 5th grader hunched over a notebook, eyes about 4 inches away from the screen. The correct distance is about 25 inches. The correct distance for reading on paper - books, newspapers, etc. - is about 15 inches.

Rule of thumb: Sit arm length away from the monitor and the length of your forearm from all printed matter.

If you are using a notebook, that would mean your arms should be stretched, if you are an adult. Small kids can’t even reach the !!! Does it make sense to type with stretched arms?

What the article didn’t mention, eye strain can also be caused or additionally worsened by a black keyboard. Everybody, even people who type with 10 fingers, look up and down between keyboard and monitor. The contrast difference between a black/dark keyboard and the bright lit screen creates additional eye strain.

Being hunched over a notebook is causing bad posture, the spine is round, the head tucked between shoulders. Most people hunch over and then look up a little bit, while ideally the neck should be straight and the chin slightly tilted towards the chest. Hands and arms are all clawed in.

Being hunched over not only curves the spine and shortens the muscles in the front but also takes volume away in the chest and doesn’t the person to breathe freely.

If it has to be a notebook, please give yourself or your kid a break and use a notebook stand to get the screen into correct position and plug in an external keyboard to allow for an upright and ergonomic posture.

Make sure there is no reflection on the screen from windows, etc.
Your eyes, your whole body will say thank you and feel much fresher once your done working.
