The loss of sensitivity in the mid to high spatial frequencies was profound during abnormal visual development, with increased deprivation leading to further contrast losses . Not only will certain disease/disorders of the eye reduce visual acuity, contrast sensitivity will also be affected (18).

The visual system, in other words, is less sensitive to very low spatial frequencies than it is to intermediate ones. As a result, there is a range of spatial frequencies, toward the center of the horizontal axis, where humans are maximally sensitive .
