Twelve exam rooms, three locations, one calibration cadence.
A multi-location optometry group standardized PV equipment across all twelve exam rooms when the practice expanded. Centralized procurement, scheduled calibration reminders, and bulk replacement chart subscriptions removed the operational overhead from individual location managers.
"We don't think about chart calibration anymore. Reminders show up, replacements ship on schedule, and our exam rooms are always within spec."

Functional Vision Assessment
Functional Vision Assessment
What is functional vision assessment?
Functional vision assessment evaluates how vision impacts real-world activities such as reading, contrast perception, mobility, and visual performance beyond standard distance acuity testing.
What is reading acuity assessment?
Reading acuity assessment evaluates reading performance, reading speed, and functional visual performance in real-world visual environments.
What is MNREAD?
MNREAD is a standardized reading acuity assessment designed to evaluate reading performance and functional vision.
What is iReST?
The International Reading Speed Texts (iReST) are standardized multilingual reading assessments utilized across global clinical and educational environments.
What is contrast sensitivity testing?
Contrast sensitivity testing measures a patient’s ability to distinguish objects from backgrounds with varying levels of contrast.
Why is contrast sensitivity important?
Reduced contrast sensitivity may affect everyday activities even when standard visual acuity appears normal.
