Scientists create a cyborg eye that mimics the real thing

This isn’t just about cosmetic similarity. In some ways, it’s close and even superior to organic eyes. Its responsivity is nearly the same across the visible light spectrum, while its response and recovery times are faster. The nanowires are even denser than the photoreceptors in a real eye.

It’ll be a long while before an artificial eye like this is ready to restore sight. Its 100-degree diagonal viewing angle isn’t as wide as the 130 degrees of the real thing, although that can be improved. The total light-detecting area is just 0.08in wide, and its 100-pixel resolution is well below what you’d need for a meaningful image. The current manufacturing process is also expensive and slow, while there’s a chance the materials will lose effectiveness over time.

Still, this promises to be a milestone for cyborg eyes. With enough refinement, this could lead to implants that restore eyesight while preserving the natural look. The scientists also believe they could one day power the eye with sunlight — you might not need a separate power source, at least until it gets dark.
