All Leica eyepieces are also available with built-
in dioptric correction, allowing the microscope
to be used without glasses even by those with
vision problems. The correction comprises
±5 diopter settings. Using the Dioptric Correction
1. Set the dioptric correction of both eyepieces
to the mid position ("0" diopter settings).
2. While wearing your glasses, look through
the eyepieces and focus on the specimen.
3. Rotate both eyepieces to the maximum
value of "+5".
4. Hold one eye closed and rotate the other
eyepiece in "-" direction until the specimen
appears sharp.
5. Then, open the other eye and correct the
diopter settings until the image is uniformly
sharp.
