Explanation: There are two types of photoreceptors in our eyes Rods - They are responsible for vision at low-light levels. Cones - They are responsible for vision at higher light levels. Rods aid in peripheral vision and are located outside of the central part of the retina

Webbrod, one of two types of photoreceptive cells in the retina of the eye in vertebrate animals. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system.

This requires the movement of lots of molecules, which they need to replenish to keep working. Because the RPE is right next to the discs, it can easily help reload photoreceptor cells and discs with the molecules they need to keep sending …
