eye pieces

The eye piece (or eyepieces in this case) usually magnify the virtual image by about 8 to 12.5X, thus allowing you to see the object that you are focusing on, as an enlargement. Binocular microscopes such as this Zeiss, are more comfortable to use for an extended period of time as eyestrain, which often occurs when using a compound microscope with one eyepiece, is minimized.
