ABSTRACT:
A headband magnifier comprises a one-piece polypropylene headband having a front portion, a back portion and two opposed sides where the back portion is disengageable so that the headband is movable between an at rest position and a compression position for the headband to provide a compressive force. This headband compressive force provides a comfortable tension for all head sizes. The headband magnifier further provides a flexible holding member having a continuous groove that facilitates interchangeability of lenses.
