      I’m confused as to why,when exposed to bright light, rod cells cease to function.

      I understand that exposure to bright light bleaches all of the rhodopsin, but…so what?

      Why doesn’t the bleached product (opsonin/retinal) simply get re-synthesised back into rhodopsin as it does in dim light, and therefore continue the cycle and enable impulses?
