some tips for Eye safety:

some tips for Eye safety:

* Choose a monitor that tilts or swivels, and has both contrast and brightness controls.

* Arrange workstations and lighting to avoid reflected glare on the display screen or surrounding surfaces.

* Reorient the workstation so bright lights from open windows are at right angles with the computer screen.

* Set the computer monitor for dark characters on a light background; they are less affected by reflections than are light characters on a dark background.

* Sit about 20 inches from the computer monitor, a little farther away than reading distance, with the top of the screen at or below eye level.

* Adjust monitor angle and/or lighting to reduce neck/eye strain; adjust screen intensity for sharper images.

* Place your screen and document holder at the same distance from the eye to avoid frequent refocusing and movement of the neck or back.

* Take periodic rest breaks, and try to blink often to keep your eyes from drying out.

To Avoid back pain:

Most back problems that occur in the workplace are caused by physical stress, such as being in an awkward position for a long time, making the same motions over and over, and simply using your back too much. These injuries can cause stress and strain on muscles, nerves, tendons, joints, blood vessels, or spinal discs.

Arrange your work to help prevent work-related injuries. It is important to position yourself so that you can sit comfortably and minimize stress on any one area of your body. Change your positions and tasks as often as possible, and match tools to your size and preferences. If you are doing a job or task that requires you to sit for long periods, get up and stretch and move around at least once an hour.
