Virtually all visual discriminations become less accurate when either the luminance or the duration of the stimulus is reduced. An exception is found for wavelength discriminations near 460 nm, where an increase in either luminance or duration can cause the threshold to rise. For flashes of 100 msec or less, the critical variable is the total energy of the flash (i.e. the product of retinal illuminance and flash duration), and wavelength discrimination is optimal at an intermediate value… CONTINUE READING
