title: [Lanthony's New Color Test. V. Classification of the grays].
abstract: It is easy to make a shortened Lightness Discrimination Test (LDT) using the grey caps of the New Color Test (NCT). The shortened test shows the reduction in contrast sensitivity as well as the original LDT in squint amblyopia multiple sclerosis, optic neuritis and cerebral tumours. So it is a useful complement to the NCT.
