Abstract
A medical/dental loupe assembly provides through-the-lens oculars with an inconspicuous interpupillary distance adjustment capability. The system includes a pair of lenses, each lens having a telemicroscopic ocular cemented therethrough, and an upper portion, one on each side of a wearer's nose. A generally horizontal slot is formed in the upper portion of one of the lenses, and a bridge member connects the upper portions of the two lenses. The bridge member has two ends, one end of which is coupled to the slot through a fastener that may be loosened and tightened, thereby allowing the distance between the oculars to be adjusted and locked into position in accordance with the interpupillary requirements of a user.
