"Standardization of visual acuity measurement is essential for accurate monitoring of the response to treatment in individual patients and in clinical trials. By consensus of experts, the Early Treatment for Diabetic Retinopathy Study (ETDRS) logMAR charts have become the gold standard for adult visual acuity testing."

Precision Vision’s Computerized Visual Acuity Testing suite (PVVAT) utilizes specialized crowding bars for letter isolation to achieve E-ETDRS benchmarks. Validated extensively by the Jaeb Center for Health Research since 2012, the PVVAT engine provides exceptional test-retest reliability parameters in perfect agreement with our gold-standard physical ETDRS charts.

Precision Vision’s PVVAT brings a modern image to the examination lane while actively optimizing performance metrics and diagnostic quality. Eye care professionals worldwide recognize the strict correlation between reliable, repeatable visual acuity data sets and the uncompromised accuracy Precision Vision builds into every platform.

We have deeply understood this critical environment since 1965, keeping our primary focus anchored on manufacturing the highest quality vision testing devices in the world.
