WebStructure. Rods are a little longer and leaner than cones but have the same basic structure. Opsin-containing disks lie at the end of the cell adjacent to the retinal pigment epithelium, which in turn is attached to the inside of the eye.The stacked-disc structure of the detector portion of the cell allows for very high efficiency. Rods are much more common than … WebRods have a response range of 3 orders of magnitude, up to 10,000 photons/sec (mesopic vision), at which point they saturate. When rods saturate cones start responding (photopic vision), and by shifting their operating curves, cones take the human eye out to 10 billion photons/sec: noon sun on freshly fallen snow at altitude. 9 orders of magnitude! earlylearn access nyc
