We show, how sensitivity to sinusoidally-modulated gratings changes throughout the course of dark adaptation. The luminance required to resolve the bars of a variety of sinusoidal gratings of (0.6-14 c.p.d.) presented in the parafovea, was determined for 30 min following a full bleach. Data obtained...
