2. To assess the fit between a person and their work, ergonomists recommended that the
optimal screen position should be slightly below eye level. Viewing angle should be
approximately 10°-20° downward onto
the screen’s center. The lumbar (bottom five
vertebrate in the spine) needs to be supported to decrease disc pressure. Sitting in a chair
with a backrest that inclines backwards and has adequate lumbar support is critical to
prevent excessive lower back pressures. The recommended ergonomic seating position
to minimize pressures is to sit with the wrists straight at a 90° angle from the floor and seat
and knee angle must also be at a 90° angle. Angular adjustment to reduce reflection on
your monitor should range from 5° forward tilt to 15° backward tilt (
