Terrific explanation! Why would the fovea be recessed relative to the macula and the rest of the retina? If the best focus of the lens is in the recessed part of the fovea, then optimally, the entire retina should be a continuous curve where the lens has its best focus. For comparison, camera lenses focus on a consistent surface (optimized for the flat film plane). They don’t have or need a dual-zone focus. Is this a screw up on nature’s part? Thanks, Steve Hines
