Ultraviolet sensitivity of three cone types in the aphakic observer determined by chromatic adaptation.
Sensitivities at 5.5 deg off-fovea from the aphakic observer superimposed on orange, purple and blue fields were obtained to estimate short-, middle- and long-wavelength cone spectra respectively. The middle-wavelength mechanism had a visible wavelength maximum resembling a nomogram plus an UV sensitivity fitting a cis-peak. The short (and, to a lesser extent, the long) wavelength cone sensitivities are higher in the UV than expected.
