Abstract
A headband to be worn on the head of a person making an examination, with an examination instrument such as an observation unit and an illuminating unit supported from the headband so as to be adjacent the eyes of the examining person. A counterweight on the rear of the headband counterbalances some of the weight of the examination instrument at the front, and makes the headband sit more evenly and comfortably on the wearer's head. The counterweight may contain a power pack, such as rechargeable batteries, providing power for the illuminating unit through a cord extending along one side of the headband.
