Abstract
Visual acuity was psychometrically measured over a wide range of luminances for four amblyopes to explore the contention that amblyopic eyes improve in acuity in dim light and have an acuity equal to or better than the normal eye. In our experiment, acuity of the amblyopic eyes did not improve with low luminance but declined as for the normal eyes. At essentially all luminances, acuity of the amblyopic eye was less than that of the normal eye, and at the lowest luminances both eyes approximated each other in acuity.Keywords
