A single-lens optical device worn over one eye, held in place by a magnetic temple clamp. The TrueSight processes visual data through three layers — magnification, spectral analysis, and material composition overlay. It looks like an antique monocle reimagined with matte-black housing and a faintly glowing lens rim.

Favored by appraisers, forensic investigators, and the kind of collectors who need to verify authenticity before committing to a purchase. The TrueSight has become an unexpected fashion accessory in Spire social circles, where wearing one implies discerning taste and the wealth to afford precision optics.
