Abstract
Disclosed herein are system and method for testing and analysis of visual acuity and changes using an acuity model, the acuity model generated based on one or more acuity chart design parameters and candidate acuity parameters calculated using the acuity test data of the subject, the acuity model comprising a chart-specific psychometric function determined using a family of multiple-optotype psychometric functions, and wherein the acuity model is configurable to estimate possibility of obtaining the acuity test data of the subject.

A system for determining a state of a subject's vision, comprising:
- a digital processing device comprising an operating system configured to perform executable instructions and a memory;
- and
- a computer program including instructions executable by the digital processing device configured for:
- (a) receiving health data of a subject;
- (b) generating one or more acuity charts based on one or more acuity parameters and the health data of the subject, wherein each of the one or more acuity charts comprises a rank based at least in part on the health data of the subject;
- (c) presenting, to the subject, a first subset of the one or more acuity charts based on the rank of the one or more acuity charts;
- (d) collecting a first acuity data of the subject from the one or more acuity charts presented;
- and
- (e) determining a state of the subject's vision based on the first acuity data.
