Our Vision
Advancing Reliable Vision Assessment for Generations
For decades, Precision Vision has supported the advancement of ophthalmology, optometry, low vision rehabilitation, education, and visual function assessment through clinically trusted testing solutions designed for consistency and reproducibility. Our commitment to scientific rigor, precision manufacturing, and standardized methodologies continues to support evolving ophthalmic and vision science needs worldwide.
Precision Vision started because the visual function tests being used in clinical research were not built for clinical research. They were classroom charts and clinical instruments adapted in the field. The endpoint data showed it.
Our founder built the original ETDRS-Revised series to fix that. The chart became the standard for retinal trials within a decade. Today, more than fifty years later, it remains the most-cited visual acuity instrument in ophthalmology research, used in landmark studies including ETDRS, AREDS, AREDS2, DRCR.net, and most major retinal and vision trials of the last thirty years.
Vision testing is a measurement instrument. Treat it like one, or your endpoint data will reflect the lack of rigor.
What we make
Visual acuity charts (ETDRS Revised 2000, Sloan Letters, HOTV), contrast sensitivity instruments (Pelli-Robson, Mars), color vision tests (Farnsworth-Munsell, Ishihara), low vision assessment tools (low-contrast acuity charts, simplified optotypes), reading speed instruments (iReST in seventeen languages), pediatric optotypes (Teller Acuity Cards), and the hardware that supports them — illuminator cabinets, mounts, calibration equipment, and replenishment consumables. Over 2,300 distinct products across nine instrument families.
Every chart, every illuminator, every accessory is produced under ISO 13485:2016 quality management at our Woodstock, Illinois facility. Every product family has been validated, peer-reviewed, and accepted by FDA, EMA, PMDA, and other major regulators as primary endpoint tools.
Who we serve
Clinical trial sponsors and CROs running ophthalmology, retinal, and neurology studies. Academic researchers conducting investigator-initiated work. Practicing ophthalmologists and optometrists equipping exam rooms. K-12 vision screening programs. Regulators evaluating vendor credibility for vendor files.
How we operate
Single facility. No outsourcing of any function. The same team that builds the equipment also handles calibration, packaging, and shipping. Every step is documented, every batch traceable, every unit identifiable to the operator who built it. Decisions stay close to the work — owner, GM, and product specialist all walk the manufacturing floor weekly.
Why this matters
For sponsors and regulators, accountability is non-abstract: a real person, a real direct line, a real signature on the documentation package. For practices and researchers, the same team that helps you spec the equipment is the team that supports you years later when something breaks. The same standards we apply to manufacturing, we apply to support.
This isn't a marketing position. It's an operating reality. It's why our team tenure is measured in decades, not quarters.
The team accountable to every claim on this site.
