Since you are not immersed in the world of woo-woo, you do not understand the implications of losing 90% of what you see, so that you can gain... IR vision? Telescopic sight?

The world is becoming more spiritual. Materialsm is toast; animism will be shown to be much more accurate. So, by the time we get to making cyborg eyes, we will be at the level of understanding much more of what our eyes actually see (such that replacement will seem silly) and we will also have the medical science of actually healing the body.

In regenerating limbs, I am not talking about genetic engineering, I am talking about communicating with the body and restarting the process that developed the limb in the first place. In sci-fi language, all the machinery is still there, its just no one knows what it does or where they on/off switch is.
