Systems and methods for testing and analysis of visual acuity and its changes

A system for adaptively evaluating visual acuity of a subject, the system 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 to create a scoring application comprising a software module configured for:
• (a) obtaining one or more acuity chart design parameters;
• (b) collecting acuity test data of the subject;
• (c) generating one or more sets of candidate acuity parameters based on the one or more acuity chart design parameters and the acuity test data of the subject, wherein each of the one or more sets of candidate acuity parameters comprises a rank obtained by analyzing the acuity test data of the subject;
• (d) generating a plurality of candidate acuity charts based on the one or more acuity chart design parameters;
• (e) ranking the plurality of candidate acuity charts based on the rank of each of the one or more sets of candidate acuity parameters;
• and
• (f) selecting one or more acuity charts from the plurality of candidate acuity charts based on the ranks thereof to be presented to the subject for acuity testing.
