Microscopes are demanding when it comes to the working posture. Observing samples requires full concentration and looking through the eyepieces usually involves inclining the head and back, so that one’s eyes, neck, shoulders are properly positioned. This can, in some cases, cause the operator to suffer from strain. Once a microscope user feels physical discomfort, he or she may try to avoid a certain posture, even adding further to the strain – a vicious circle.
Also the knees and feet may be affected, even jaw joints may ache due to grinding of teeth from tension, or headaches can occur. This is especially true if microscope users spend a long periods of time using a microscope. If these issues are not addressed over an extended period can lead to serious health issues.
