Eye Chart Test by Dr. Evans
Clinical Vision Check at Home
$2.99 · Designed for iPad. Not verified for macOS.
Point. Read. Know your vision. Built by an OD, tested in real clinics. One purchase — no subscription, no account, no nonsense.
Are your eyes as sharp as you think?
Eye Chart Test is the most accurate vision screening app on the App Store, designed and calibrated by Dr. Ryan Evans, a licensed Doctor of Optometry. It uses the same Sloan letter standard found in real eye clinics, not a rough approximation.
WHY THIS ONE IS DIFFERENT
Most vision apps just show big letters on screen. This one is actually calibrated. It knows your exact device's pixel density, adjusts for your testing distance, and delivers a true LogMAR result -- the same scale your eye doctor uses to record your prescription.
WHAT YOU GET
- Clinically calibrated Sloan letter chart (the gold standard in acuity testing)
- Tests both eyes separately -- right eye (OD) and left eye (OS)
- True 20/20 to 20/200 scoring on the standard visual acuity scale
- Mirror mode for accurate 10-foot distance testing at home
- Hands-free voice recognition -- just say the letters aloud
- Shareable results card to send to your doctor or friends
- Glasses vs. uncorrected comparison built in
DESIGNED BY A REAL DOCTOR
Dr. Ryan Evans is a practicing Doctor of Optometry. The testing protocol, letter sizing, and pass/fail logic are all based on actual clinical standards used in professional eye exams.
WHEN TO USE IT
- Quick check between annual eye exams
- Wondering if your prescription has changed
- Monitoring a family member's vision
- Anyone who wants to know their actual number
IMPORTANT: This app is an educational screening tool and is not a substitute for a comprehensive eye examination. If your results suggest reduced vision, we recommend scheduling an exam with your local optometrist.
