ABSTRACT:
There is disclosed a hand-held magnifying apparatus which employs a lens assembly housing. The housing has first and second magnifying lenses located therein whereby the lenses can be adjusted to obtain a variable focal length. The housing is terminated at one end in a cylindrical hooded section which has coupled thereto an angled power source accommodating section. The power source accommodating section includes a source of illumination and cylindrical condensing lenses which operate to condense the light pattern from the illumination source and to change the light pattern from an elliptical to a circular pattern to thereby uniformly illuminate the text or material to be viewed via the magnifying lens assembly.
