VisiontoVision is an Android app designed to provide an easy way to test your eyes at home. By following simple instructions, users can hold their phone at an approximate distance of 40cm and read letters displayed on the screen. The app progressively decreases the size of the letters to test visual acuity for both the right and left eye. At the end of the test, users receive a result page showing visual acuity for each eye and estimated power.

To use the app, users need to find a quiet place, keep their phone at a 40cm distance, and read the letters displayed on the screen. By clicking the mic button, users can read the letters aloud, and the app provides immediate feedback by turning correct responses green and incorrect responses red. The letter size decreases as the test progresses, offering an estimate of the user's eye condition.
