Heru Pretest Pro is software that turns any commercial VR headset (Pico, Meta Quest) into a Bascom Palmer Eye Institute–validated clinical instrument delivering every clinically decisive functional vision exam in a single 140-second handsfree session, Visual Acuity, Visual Field, Quantitative Pupil, Quantitative Cover Test, and Extraocular Motility. The industry-standard equivalent requires legacy devices, manual work, and 15–20 minutes of skilled technician time. Pretest Pro compresses that to 140 seconds on one commercial headset. Visual Field is validated at ICC 0.97 against the Humphrey Field Analyzer running SITA Standard. FDA-registered (Class I, 510(k) exempt). Software-updatable over the air; new tests deploy without new hardware. Built on the Heru platform: 1.85M+ eyes tested, 25+ peer-reviewed publications, 75 patents, and clinical lineage from Bascom Palmer Eye Institute, the #1-ranked ophthalmology hospital in the US.
