In an attempt to evaluate our capacity to perceive distortions produced by ophthalmic lenses, the capacity to detect curvature for static, drifting, and warping stimuli was assessed for five different eccentricities. In general, the data show that for central vision there is no difference between the static and dynamic conditions for curvature thresholds. However, at 5 deg of eccentricity and beyond the subjects appear more sensitive to the dynamic stimuli. New methods for improving our assessment of curvature detection and perception are presented. Our intention is to generalize these methods to evaluate the effect of aging on the capacity to perceive distortions in the real world.
