Abstract: Visual acuity (VA), the cornerstone of eyecare, can yield symptoms despite 20/20 [ 1 ]. Optimal VA is 20/10 based on cone spacing. Vernier acuity (minimum misalignment) is 3” arc, 10x < cone spacing, a hyperacuity mediated by visual cortex [ 2 , 3 , 4 ]. Minimum visible acuity [ 2 ] (MVA, thinnest black line detectable on white background) is 1” arc. Hence MVA (pilot avoiding fine wire), is a potential hyperacuity never used clinically. We describe a cone specific test of MVA, including monocular, binocular, chromatic, and orientation specific performance.
