Abstract

To investigate the effect of induced intraocular straylight on the Farnsworth–Munsell 100-hue test performance in individuals with light and dark irides, 28 young subjects were tested both with and without a quantified light scattering filter. The filter produced a significant increase in the total error scores (p <0.05), but no significant correlation was found between the level of straylight and error score (p > 0.05). The development of a tritan-like defect in the dark-eyed participants can be attributed to the effect of light attenuation caused by filter absorption, which markedly affects S-cone mediated color discrimination. The combined effect of higher short-wavelength absorption of melanin and macular pigment in the dark eyes may be involved.
