Classic - 1st Generation Double Aspheric Revolutionizing Binocular Indirect Ophthalmoscopy (BIO) Lenses
In 1956, aspheric ophthalmic lenses for subnormal vision were developed by Dr. David Volk. He found that an aspheric surface corrected the aberrations present in more common spherical lenses. Several developments occurred with the aspheric lens designs through the years, delivering far superior imaging for BIO examinations. In 1982 all Volk lenses for indirect ophthalmoscopy were redesigned with both surfaces aspheric, providing a substantial improvement in image quality. The 20D and other Volk BIO lenses have been known as the industry standard for decades, and are still widely used in every corner of the world today.

Digital - 2nd Generation Binocular Indirect Ophthalmoscopy (BIO) Lenses
In the Volk spirit of improvement, our 2nd generation BIO lenses were developed to deliver enhanced resolution (‘Clear’) lenses. Working with a high grade glass, we looked at all aspects of the double aspheric design with advanced computer modeling techniques with the goal to evolve the BIO lens. We realized improvements in all aspects of the BIO lens capabilities, ultimately delivering the best image quality attainable for Indirect Ophthalmic exams.
