Our stimuli were generated on a fully calibrated colour monitor optically incorporated within a Maxwellian view system. We used a radially symmetric version of

Measurements for a patient with an acquired colour vision deficiency demonstrate that her opponent responses are abnormal, although she can perform normal colour matches with a 1° 20′ bipartite field.

Standards for colour vision were introduced for the maritime and railroad transport in the 1870s and for aviation in 1919. Colour vision standards for drivers of motor vehicle

Cyanopsia has been observed after cataract extraction. We made a yellow-tinted posterior chamber IOL, called the UVCY-IOL, to sustain normal color vision postoperatively. In transmittance, the UV
