Apparatus and method for converting a standard non-rotatable diagnostic lens into a rotatable diagnostic lens for evaluation of various portions of the eye

In a lens device for examining portions of the human eye including a housing member having opposed end portions and associated wall means, the housing member having a viewing lens positioned adjacent one end portion thereof and at least one mirror located adjacent the viewing lens, the improvement comprising first and second cooperatively engageable peripheral members, said first peripheral member being fixedly attached to the wall means associated with the housing member, said first peripheral member being rotatably moveable relative to said second peripheral member when engaged therewith such that when said first peripheral member is fixedly attached to the housing member the at least one mirror is selectively positionable relative to a portion of the human eye to be examined.

A lens device for examining portions of the human eye comprising a housing member having opposed end portions and associated wall means, said housing member having a viewing lens positioned adjacent one end portion thereof and having at least one mirror located adjacent said viewing lens, said housing member further including a groove formed in its associated wall means intermediate the opposed end portions thereof, and a peripheral member cooperatively engageable with said groove, said housing member being rotatably movable relative to said peripheral member such that the at least one mirror is selectively positionable relative to a portion of the human eye to be examined.
