Strong Vision Technologies, 78D Aspheric Condensing Lens

78D Condensing Lenses Aspheric and Anti-Reflective Coat The 78D slit lamp lens offers a bit more magnification than the 90D. This larger image size can assist in assessing pathologies you might not see with the 90D. Corrected for field curvature, and aberrations. The 78D is a perfect lens addition to help you in your observations. These offer an ideal combination of field of view and magnification. The increased mag will provide unsurpassed clarity of the fundus, arteries, veins and optic disc during your evaluations. The lens will also extend the working distance from cornea compared to the 90D which can be important to nervous patients. We don't stamp our name on the lens frame and charge double (but maybe we should). Try one of our 78D lenses. If not satisfied, return for a risk free refund within 30 days. Yes, it comes with a case.
