Clear Image Microscope Glasses are two high powered, coated lenses “piggybacked” one behind the other. This “doublet” lens is designed to create a magnified, crystal clear, edge-to-edge image. The lens eliminates the aberrations and “pincushion” effect of a single high-powered lens. In addition to these benefits, the patient’s eyeglass prescription is ground into the rear lens to account for refractive conditions like myopia (near-sighted), hyperopia (far-sighted), and astigmatism. By combining high powered magnification, edge-to-edge clarity, and refractive prescription in one pair of glasses, patients can achieve amazing results in reading smaller print than previously thought possible!
