How to use your printed chart

Print at 100% scale ("Actual size" in the print dialog — never "Fit to page"), then put a ruler on the top optotype: it should measure the height printed in the chart footer. Tape the chart at eye level in even lighting, measure the exact distance you selected, cover one eye without pressing on it, and read down to the smallest line you can. The 20/20 row corresponds to logMAR 0.0 — the smallest detail a "normal" eye resolves at the chart's design distance.

Every optotype here is the same vector geometry our clinical software renders in exam lanes — Sloan letterforms, the standard Tumbling E, and an ISO 8596-proportioned Landolt C — sized by the same MAR formula, with each row labeled in both Snellen and logMAR. Convert between notations with our free visual acuity converter, or read the full sizing reference on the visual acuity chart page.

A printed chart is a screening aid, not an eye exam. It cannot detect eye disease, refractive detail, or binocular problems — see an optometrist or ophthalmologist for a comprehensive examination.

Paper is a screening.
Screens are a system.

For the exam lane, Ocular Edge runs calibrated, randomized charts on any TV — 20 chart types, ETDRS scoring, remote control — from $24.99 per lane.
