Why Ocular Edge

Your exam room,digitized.calibrated.

A $3,000 chart box, replaced by the TV already on your wall. Every optotype is a geometric vector path following ETDRS and ISO 8596 letter-geometry conventions, sized by the clinical logMAR formula and verified against a physical ruler — never browser-reported DPI. Pair a display with a 6-digit code and you're testing patients in two minutes.

Clinical Grade

The clinical standard for digital visual acuity testing.

Ocular Edge is the first digital visual acuity system built to replace your wall chart with clinically validated precision on any screen. Every optotype is rendered using the ETDRS logMAR formula — letterHeightMm = distanceMm × tan(MAR × π / 10800 × 5) — ensuring that at 20 feet, a 20/20 letter measures exactly 8.87 mm, and a 20/200 letter measures 88.7 mm.

Unlike digital eye chart apps that scale fonts or rasterize images, Ocular Edge uses geometric vector paths for every optotype in the Sloan, ETDRS, Tumbling E, Landolt C, and pediatric chart sets. Combined with physical ruler-based screen calibration — never relying on browser-reported DPI — the result is clinical-grade optotype rendering to ±0.05 mm precision on every TV, monitor, or tablet in your optometry or ophthalmology practice.

Whether you are testing with the Sloan optotype set for standard acuity, ETDRS LogMAR scoring for clinical research, or HOTV for pediatric amblyopia screening, every line of every chart is rendered at the exact size your patient is meant to see — on a Smart TV, an Android tablet, or a browser-based PWA in your exam lane.
