The Clinical Use of Vernier Acuity: Resolution of the Visual Cortex Is More Than Meets the Eye
Vernier acuity measures the ability to detect a misalignment or positional offset between visual stimuli, for example between two vertical lines when reading a vernier scale.It is considered a form of visual hyperacuity due to its detectable thresholds being considerably smaller than the diameter of a foveal cone receptor, which limits the spatial
