Similar Dependence of Acuity Measures on Exposure Duration Irrespective of Acuity Level in Artificially Degraded Vision.

The present study confirms previous findings also for the case of reduced acuity. The data suggest that small physiological fluctuations in retinal image quality are not a dominant factor regarding the effect of presentation duration. Overall, and in particular for sub-second presentation durations, there is little difference between normal and degraded vision.
