Abstract
Optical systems of large aperture which allow observers to view with both eyes a magnified image of a small object are now known as Biocular Magnifiers. For high magnification lenses of numerical apertures approaching unity are required and the control of aberrations becomes difficult. As the normal visual apparatus has adjustments for accommodation and vergence together with the fusion compulsion it may be able to accept larger aberrations in a magnifier than a photographic plate, say, can tolerate aberrations in a camera lens. Unfortunately, much more is known about visual thresholds than visual tolerances and no design specifications are available.
