About the application:

Prevention is better than cure. Designed for kids older than 6, parents with young kids, and general practitioners, this apk displays optically precise optotypes of eye charts for you to measure distant visual acuity accurately in order to detect nearsightedness or myopia early, so you can take preventive measures and seek assist from medical professional early to prevent pseudomyopia from becoming myopia, or prevent nearsightedness from getting worse. Supported Eye Charts: 1. Snellen Chart, with C, D, E, F, H, K, N, P, R, U V and Z, as defined in BS 4274-1:2003 2. Tumbling E Chart. Option to have shorter middle arm. 3. Landolt C Chart 4. ETDRS Chart, with C, D, H, K, N, O, R, S, V, and Z 5. HOTV Chart 6. ETDRS European-wide Chart, with H, K, O, E, P, X, B, T, M and A 7. Numbers Predefined Try Distances: * 6, 5, 4, 3, and 2 meters * 20, 15, 12, 10, 6 feet Scenarios: 1. "Doctor" and "Patient". 2. Self-diagnosis with a mirror. With one eye covered by an eye patch and holding the device near the shoulder, you stand in front of a typical bathroom mirror using the mirror mode of the apk and having the device's screen facing the mirror. The actual try distance is 2 times of the distance between you and the mirror. 3. Self-diagnosis with a Bluetooth keyboard. After putting the device standing a few meters away on a table, you use the keyboard's direction keys to indicate what your read. 4. Self-diagnosis within arm's reach. Notations： 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 In Auto scoring, you use the swiping gestures to indicate correct readings or wrong readings, and the apk calculates the score. For LogMAR notation, the score is (LogMAR value of the best line read) + 0.02 x (number of optotypes missed). And the maximum missed is 3. For VAS notation, the score is an inversion of the logMAR scale, based on VAS=100-50xlogMAR. For another notations, the score is the notation value of the best line read and optionally minus number of optotypes missed, and the maximum missed is 2. By default, setting "Play Interval Until Next Optotype" is none. Accessible intervals in second contains: 2, 4, 6, 8, and 10. If the "patient" should not recognize the optotype within the interval, this counts a miss. Through enabling “Record Scores” in Settings, you can hold track of the progression of your visual acuity. Visual acuity scores of multiple testees should be recorded. Visual Acuity Score (VAS) is an inversion of the logMAR scale, based on VAS=100-50xlogMAR. It is more intuitive since higher values indicate better visual acuity. In the scores review, score 100 in blue indicates the reference standard, scores above 100 in green indicates no myopia, while scores below 100 in red may indicate myopia. You may copy the scores of current patient to the device's clipboard, then you may paste the scores to a drafted Email notice or instant notice. This may be handy for telemedicine / telehealth session when the medical practitioner asks for VA scores. Testing for myopia takes a few procedures and the first step is often to check distant visual acuity through a visual acuity chart. And the decrement of visual acuity may indicate the development of myopia. Disclaimer: While this apk may replace eye charts in print, however it cannot replace doctors and optometrists who carry out comprehensive tests for your eyes. Please visit optometrists regularly and seek assist from medical professional at early signs of visual acuity issues.
