Samenvatting
It is shown that (1) the dynamic properties of transduction by the photoreceptors can cause visual acuity to be significantly affected by motion within the domain of biologically meaningful velocities and (2) eyes with better static visual acuity need faster photoreceptor dynamics if their visual acuity is to be retained up to a reasonable velocity. This requirement appears to be met by the compound eye of several different species, and in a given eye it changes its state of adaptation.
