Abstract

Abstract Lansford and Baker recently demonstrated that the adaptation state of the contralateral eye effects the sensitivity of the test eye during dark adaptation. Specifically, a smaller and dimmer contralateral preadapting field which partially overlaps the preadapting field seen by the test eye accelerates subsequent monocular dark adaptation. The present study replicated the interocular light adaptation (Lansford-Baker) effect and produced the same effect under different test conditions. By the use of limited wavelength contralateral preadapting fields it demonstrated the interocular light adaptation effect in both cone and rod segments of the dark adaptation curve and that the rod effect is larger. Both long and short wavelength contralateral preadapting fields enhanced the effect to the point of doubling its magnitude.
