Dr McKeefry used stimuli at different wavelengths to ‘silence’ the L – and M-cones as well as the rods thus only the indicators from your S-cones are found. The technique may be the initial to silence these three collectively and so is recognized as ‘triple silent substitution’. He tested the technique on 16 volunteers with normal color eyesight, two sufferers previously identified as having blue cone monochromatism and something patient that has enhanced S-cone symptoms . BCM is really a genetic disorder where in fact the L – and M-cones don’t function whatsoever, resulting in impaired colour eyesight.
