The effect of WebOn another hand, blue and white lights should activate two main pigments with similar absorption spectra in retinal photoreceptors: rhodopsin in rods and the “green” long/middle (L/M) wave-sensitive opsin in cones (but very weakly shortwave/ultraviolet (S/UV)-sensitive opsin), as predicted by their spectral sensitivity functions (Peirson et al., 2024).

WebClassification models operating on one and two optimal spectral bands were developed and compared to the classification model operating on the full VIS/NIR (400-1000 nm) range. Classification sensitivity of 70% and specificity of 94% for one-band model, and 96% and 98% for two-band model (sensitivity and specificity respectively) were achieved. WebRods are more sensitive to light than cones. However, rods are not sensitive to different colors as there is only one kind of rod. For this reason, human vision is unable to distinguish colors under low light conditions. However, rods are very effective under low light conditions below 0.001 cd/m 2.
