The Visibly Digital Acuity Product (VDAP) is a web-based, self-guided software application intended for use by adults, ages 22 to 40, at home, to evaluate visual acuity with or without correction. The standalone software application allows the user to interface with the software via a web browser on two internet-enabled devices:
* A computer screen (the Display) which displays optotypes
* A touchscreen mobile device (the Remote) which operates as a remote control and interface for the user to respond to prompts related to the optotypes appearing on the Display while standing 10 feet away
The software allows users to view and respond to displayed optotypes and uses the responses to categorize a user's visual acuity into one of two buckets:
* 20/25 or better
* Worse than 20/25
