Precaution while using Microscope

Main requirements

The bench height is important and ideally it should be adjustable so that eye piece height is adjustable but this is often not practicable due to cost. What follows will be based on a fixed bench height. Microscopy requires a good seating position in an adjustable, ergonomically designed chair. The back should be high enough to support the shoulder blades and be adjustable for height and angle, with the most prominent part being the lumbar support. The seat should be low enough to have the back perfectly straight to see through the oculars. Then move the chair towards the bench so that the chair fully supports the back this feels unnatural at first. Most people have the seat too high, which results in hunching. Sitting for long periods places strain on the lower back.
