Abstract
An optical system is capable of enhancing vision of low vision individuals using a simple adjustment mechanism that requires a minimum length of travel to effect a desired adjustment. First and second substantially perpendicular mirrors are mounted in a cluster for pivotable movement. An entrance mirror is pivoted in response to pivoting movement of the mirror cluster so as to ensure proper convergence when the object to be viewed is close to the objective lens or lenses in a binocular system. The system also includes an objective lens and an eyepiece lens and is readily mounted to a conventional eyeglasses frame.
