Light micrographs of longitudinal sections of the eye. a Dark-adapted male from the Niigata strain. b Light-adapted, Niigata. c Dark-adapted, Nagano. d Light-adapted, Nagano. e Absorption spectra of distal pigmented (DP) and proximal pigmented (PP) regions, which are exemplarily indicated by squares in d. Circles indicate IMSP data and the lines indicate heuristically modeled fits (Table 1). Average of the measurements from 3 points in each strain. Scale bars = 50 μm
