The Tumbling E Chart app supports the Standard Tumbling E by default, while the Modified Tumbling E, which features a shortened middle arm, is optional. Predefined Test Distances: * 6, 5, 4, 3, and 2 meters * 20, 15, 12, 10, and 6 feet Scenarios: 1. Doctor–patient testing 2. Self-diagnosis using a mirror 3. Self-diagnosis using a Bluetooth keyboard Notations Supported: 1. Decimal (0.50) 2. Fraction (20/40) 3. LogMAR (0.30) 4. Fraction (5/10) 5. Fraction (6/12) 6. MAR (2) 7. VAS or VAR (85) Test Modes: 1. Manual 2. Auto Scoring – Swipe gestures indicate correct or incorrect responses, and the app calculates scores automatically. Enable "Record Scores" in Settings to track visual acuity progression, with support for multiple test subjects. Myopia screening typically begins with distance visual acuity testing. A decline in acuity may signal the onset of myopia, allowing for early intervention. Disclaimer: While this app may replace printed eye charts, it CANNOT substitute for doctors or optometrists who perform comprehensive eye exams essential to 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.
