of the 50 M grating in 27/30 trials (p < 10−5, binomial test), corresponding to an acuity of 2.3 logMAR or better, responding within 24 s on average (range: 6–91 s). In more recent tests, the participant [...] otherwise having only bare light perception, was able to successfully score a grating acuity of 2.3 logMAR or better. We continue investigating performance with stimuli at higher acuity levels and more extensive
