The app is designed for children above 6 years, parents with young children, and general practitioners.

The app helps in detecting nearsightedness or myopia early, so preventive measures can be taken, and medical professionals can be consulted early to prevent pseudomyopia from becoming myopia or prevent nearsightedness from getting worse.
1. Designed for children older than 6, parents with young children, and general practitioners, this app 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 help from medical professional early to prevent pseudomyopia from becoming myopia, or prevent nearsightedness from getting worse.
2. Visual Acuity Score (VAS) is an inversion of the logMAR scale, based on VAS=100-50xlogMAR.
3. 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.
4. Visual acuity scores of multiple testees could be recorded.
5. For other 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.
6. Through enabling “Record Scores” in Settings, you can keep track of the progression of your visual acuity.
7. It is more intuitive since higher values indicate better visual acuity.
8. 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 app and having the device's screen facing the mirror.
9. For LogMAR notation, the score is (LogMAR value of the best line read) + 0.02 x (number of optotypes missed).
10. For VAS notation, the score is an inversion of the logMAR scale, based on VAS=100-50xlogMAR.
11. After putting the device standing a few meters away on a table, you use the keyboard's direction keys to indicate what your read.
