will vary according to:

Eye accommodation capability

Working distance; longer working distance = longer DoF

Field Size (FS) – achievable FS
will vary according to:

How close the ocular is to the eye

Working Distance; longer working distance = more FS

Prescriptions

If you use any kind of prescriptive or corrective lenses (distance, reading, “drugstore readers”), you must submit your prescription to SurgiTel for you to see through your loupe correctly.

Prescriptions may only be upgraded by SurgiTel or your local optometrist.
