Scenarios:
1. Doctor and Patient.
2. Self-diagnosis using a mirror – Stand in front of a mirror with the app in mirror mode, wearing an eye patch over one eye. The effective test distance is twice the distance between you and the mirror.
3. Self-diagnosis using a Bluetooth keyboard – Place the device a few meters away on a table, and use the keyboard arrow keys to indicate what you can read.

1. Decimal (0.50)
2. Fraction (20/40)

Test Modes:

2. Auto scoring – Swipe gestures indicate correct or incorrect readings, and the app calculates scores. Enable "Record Scores" in Settings to track visual acuity progression, with support for multiple test subjects.
According to “Visual Acuity Testing for Telehealth Using Mobile Applications,” published in JAMA Ophthalmology on https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7809609/, this app (formerly known as Visual Acuity Charts) demonstrated the highest accuracy among 10 iPhone-based visual acuity chart applications.
Myopia detection involves several steps, with distance visual acuity testing often being the first. A decline in visual acuity may indicate the onset of myopia, enabling early intervention.
Disclaimer:
While this app may replace printed eye charts, it CANNOT replace doctors or optometrists who perform comprehensive eye exams essential for maintaining eye health. The app does not test for strabismus, esotropia, exotropia, hyperopia, or astigmatism—common early vision conditions. Please consult an optometrist regularly and seek professional medical advice at the first signs of visual acuity issues.
