About the app.
Do you see colors the way everyone else does? Find out in 2 minutes. Vision Test is the most complete free vision screening app — Ishihara color blindness plates, contrast sensitivity tests, visual acuity charts, astigmatism checks, and more. Every test runs offline with medically-referenced materials and delivers a clear plain-language report on what the results mean for daily life. For screening and education only — not a medical diagnosis.
