During dark adaptation, photopigments are gradually regenerated to increase the sensitivity of photoreceptors in low light conditions. Rhodopsin is not rapidly broken down during dark adaptation. The sensitivity of photoreceptors is actually increased, not reduced, during dark adaptation. Bipolar cells are not directly affected during dark adaptation either.
