Visual Acuity Charts: Accurate Eye Testing App for Early Detection of Nearsightedness
Visual Acuity Charts is an educational and reference app designed to help parents, children over 6 years old, and general practitioners accurately measure distant visual acuity. Developed by Zijian Huang, this app aims to detect nearsightedness or myopia early, allowing users to take preventive measures and seek help from medical professionals to prevent the progression of pseudomyopia to myopia or worsening of nearsightedness.
The app features optically precise optotypes of eye charts, including Snellen Chart, Tumbling E Chart, Landolt C Chart, ETDRS Chart, HOTV Chart, ETDRS European-wide Chart, Numbers, and Shapes. It supports various test distances, ranging from predefined distances of 6, 5, 4, 3, and 2 meters to custom distances ofmeters orft.
Visual Acuity Charts offers different testing scenarios such as "Doctor" and "Patient," self-diagnosis with a mirror, self-diagnosis with a Bluetooth keyboard, and self-diagnosis within arm's reach. The app provides multiple notations for visual acuity results, including decimal, fraction, LogMAR, and VAS or VAR.
With the option of manual or auto scoring test modes, users can easily indicate correct or wrong readings using swiping gestures. The app also allows users to record their visual acuity scores and track the progression over time. These test results can be shared with medical professionals during telemedicine or telehealth sessions.
It's important to note that while Visual Acuity Charts can replace printed eye charts, it cannot replace comprehensive tests conducted by doctors and optometrists. Regular visits to optometrists are still necessary, especially at the first signs of visual acuity problems.
