Abstract

Hereditary colour vision deficiency (CVD) is a non-progressive X-linked condition (8% males, 1/200 females) due to a shift in peak sensitivity of red (long wavelength, L) or green (middle wavelength, M) cones or the absence of either cone photopigments [ 1 ]. Minimum visible (detectable) acuity (MDA) is the thinnest black line detectable on a white background but heretofore has not been used clinically. Recently we developed a cone-specific MDA test [ 2 ]. We extended this research to determine if cone-specific MDA: (a) diagnoses type and severity of hereditary CVD (b) improves with colour vision correcting lenses (CCLs)[ 3 , 4 ].
