Dermatology
Use of a magnifier to view skin lesions is common practice for the dermatologist. In general clinical usage, a Zeiss D12-AR provides the best combination of magnification and field of view, especially for the scalp.
However, many physicians and nurses are accustomed to using a common large-diameter gooseneck magnifier, which typically provides only 4 diopters of refractive power. For these providers, a Zeiss D6-AR, with its large 4-inch (100mm) diameter, or a Zeiss D8-AR with 3-1/2 inch (85mm) diameter, offer a more comfortable amount of magnification and field-of-view along with 5 or more inches (125mm+) of working distance when held close to the eye.
