The cones in your eye are concentrated at the center, so your eye tends to see items directly in front of it — this means you have to continually move your eyes around to see small areas. But a camera’s photoreceptors are distributed evenly, allowing a camera to see everything in its field of view. If our eyes saw like a camera, with a uniform distribution of receptors, there would be so much stimuli in our view that our brains could never process it all, according to Taylor.
Instead, our eyes exploit fractal patterns found throughout nature to make information-processing simpler. Retinal implant designs should account for these differences, Taylor wrote.
“Remarkably, implants based purely on camera designs might allow blind people to see, but they might only see a world devoid of stress-reducing beauty. This flaw emphasizes the subtleties of the human visual system and the potential downfalls of adopting, rather than adapting, camera technology for eyes,” he wrote.
