This is a great looking infographic which has been completed by Mediaworks in conjunction with Clifton Cameras, U.K. Using sources from the BBC and National Geographic, it compares and contrasts the camera lens vs. the eye.
It’s a fairly technical piece which takes into account aperture, single-element convex lens tech, angle of incidence and then takes the reader through the three distinct layers of the eye.
It then neatly finishes with a nice little blind spot test and a general look at the various forms of animal eyes. Right, there’s an animal with eyeballs as big as its brain…
BTW, the human eye has about one million light-sensitive cells called photoreceptors. Does that make us human beings the equivalent of a 2MP camera?! In case you didn’t know, the computer pixel is basically the equivalent of a biological photoreceptor.
Like the pixels in a digital camera, each photoreceptor generates an electrical response proportional to the local light intensity. Each photoreceptor then initiates a chemical signal that is transmitted to downstream neurons, ultimately reaching the brain. But unlike the pixels of a digital camera, photoreceptors indirectly inhibit one another through laterally projecting horizontal cells… yours to decipher.
