Visual acuteness: The first step is to record visual acuity. Patients who require remedial lenses should wear them during trying. Visual acuity in each eye is tested as the opposite eye is covered.

It also allows you to perceive depth, because the two eyes see the specimen through separate lenses. The magnification of the dissecting microscope is not as great as the compound microscope. It does, however, enable the viewer to observe large specimens at a magnification up to 30X.

The photographer has the option to use a standard lens mount that replaces the eyepiece, or use a microscope with a trinocular head and mount the camera there. The images seen through a digital microscope can be saved on a computer file and viewed in a computer monitor. It is the perfect educational tool because the specimen can be viewed by a lot of people simultaneously.
