So many of us old farts face the prospect of macular degeneration years before the rest of the body fails I hope the technology is developed and is relatively cheap...
I'm with you - probably won't be cheap, but sight is the single most important sense for getting around in the world. I have a left eye that was pretty much trashed after a total retinal detachment and would pay a lot to have good vision in that eye. If I had both eyes going bad, any price I could manage would be worth it.
