用明亮的可见光照射视杆外节导致感光膜的蛋白质和脂质组分的氧化。氧化程度取决于光照的强度和时间。自由基过程的抑制剂完全抑制脂质氧化，并在一定程度上降低蛋白质氧化。脂质和视紫红质的光氧化系统对孵育介质中的氧含量也有不同的反应。视网膜是感光细胞膜的光敏氧化成分。
Illumination of rod outer segments with bright visible light results in the oxidation of both protein and lipid components of the photoreceptor membrane. The oxidation degree depends on the intensity and time of illumination. The inhibitors of free radical processes completely inhibit lipid oxidation and somewhat decrease protein oxidation. Photooxidation systems of lipids and rhodopsin also react differently to oxygen content in the incubation medium. Retinal is the photosensitizer of the oxidation of the photoreceptor membrane components.
