Clearance Volk 78D Small Aspheric Lens, Clear (31mm), with Black Ring

The Clearance Volk 78D Lens is an ideal lens for doctors who regularly cater to populations prone to glaucoma and other posterior pole abnormalities. The double aspheric design and field of view offered by a 78D offers clear and large views of the central mid-retinal regions. This lens offers a high magnification without cutting down too drastically on the field of view.  This lens is a popular choice as a general diagnosis lens among doctors who prefer a larger ring size than the more common and smaller profile of the 90D. Dilation is required to obtain optimum retinal imaging with the 78D.
