vision and computers
There are a number of things that you can do in your work station area to improve visual efficiency:
- Take alternative task breaks through out the day.
- When viewing screens with dark backgrounds, use lower lighting (about 20 to 70 foot candles or about one-half the normal office lightning).
- The brightness of the computer screen and the surrounding should be closely matched.
- The contrast between the screen background and the screen character should be high. Dark characters on a light screen are generally more legible than light characters on a dark screen.
- Minimize glare on your computer screen with a glare reduction filter (look for one with the AOA Seal of Acceptance) by repositioning your computer screen and by using drapes or window treatments. To locate source of glare place a small mirror in front of your computer screen. Keeping your computer screen clean can also help reduce glare.
- Use an adjustable chair that helps you sit at a comfortable height, angle and distance from the computer screen.
- Choose a computer with a detachable keyboard a screen that tilts and swivels and contrast and brightness controls.
- Reference material should be on an adjustable holder, close to your screen and at the same viewing distance.
