A headband magnifier (H) comprises a one-piece polypropylene headband (10) having a front portion (10A), a back portion (10B) and two opposed sides (10C and 10D) where the back portion (10B) is disengageable to that the headband (10) is movable between an at rest position and a compression position for the headband (10) to provide a compressive force. This headband compressive force provides a comfortable tension for all head sizes. The headband magnifier (H) further provides a flexible holding member (16) having a continuous groove (20A) that facilitates interchangeability of lenses (26).
