Overview
This is a classic ophthalmic phoropter, an iconic instrument of mid-century optometry used to measure refractive errors and determine eye prescriptions. Featuring a heavy, textured black 'crinkle' finish, it houses an intricate internal system of rotating lenses, prisms, and dials.
Story
Introduced in the early 20th century, the Greens' Phoropter revolutionized eye exams by combining dozens of loose trial lenses into one mechanical marvel. Millions of people have stared through these very lenses to answer the classic question: 'Better 1, or better 2?'
Maker / Origin
Bausch & Lomb, founded in 1853 by German immigrants John Jacob Bausch and Henry Lomb, grew into one of America's oldest and most respected optical manufacturers. Their precision engineering set the global standard for scientific, military, and medical lenses throughout the 20th century.
Condition & Value
The phoropter shows moderate cosmetic wear, dust accumulation in the crevices, and minor paint loss consistent with age and professional use. The glass lenses appear relatively clear but would benefit from professional cleaning; mechanical functionality of the dials has not been fully tested.

Build on this identification
Layer in sold comps, value drivers, and venue guidance.
Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
Best Venue
