Exposure to constant light causes extensive rod photoreceptor damage but spares the photopic system in albino rats. The rod branch of the dark-adaptation curve shows considerable elevation in threshold; the cone branch is hardly affected. Longer exposure and chromatic adaptation suggest that there are three cone mechanisms with peaks near wavelengths of 450,520, and 560 nanometers.
持续光照会导致白化大鼠的视杆光感受器广泛受损，但明视觉系统不受影响。暗适应曲线的视杆部分阈值显著升高；视锥部分几乎未受影响。更长时间的光照和颜色适应表明存在三种视锥机制，其峰值分别接近450、520和560纳米波长。
