Comments "It has been reported that regeneration of visual pigments is a slow process and that photoisomerization of 11-cis-retinal in rhodopsin is very rapid. In fact, complete dark adaptation in humans requires approximately 40 minutes, [primary sources] and conversion of rhodopsin to photorhodopsin requires only 200 fsec.[BNID 111395]"
