Two types of receptors were identified: Rods and single cones and no double cones were present. Rods and single cones were present in a ratio of 19:1, respectively in control group, but in experimental groups, the concentration of rods and single cones was reduced. In light exposure group, these cells were extremely elongated while in the dark adapted state their length was a little reduced in comparison with control group. But in control group, there was no remarkable difference between the average of the thickness of rods and cones in comparison with experimental groups. ER -
