Abstract
Abstract A mirror and lens assembly which is particularly for use by a person who normally requires corrective means, such as ''''glasses'''' as a visual aid for observing objects relatively close to his eyes. The invention is particularly adapted to serve as a ''''closeup '''' mirror unit for a farsighted person when the person is not wearing his corrective ''''glasses.'''' A lens is disposed in front of a mirror, either in engagement therewith or spaced slightly therefrom, to refract light rays which are reflected from the mirror.
