I have permanent damage on my retina of other eye. I hope one day humans could regenerate their retinas as sharks and zebrafish can do. Seems strange, that fish living in deep dark oceans can fix their eyes, while most mammals who rely on vision a lot more cannot.
The article talk about DNA repairs, helping the eye to maintain its function in the long run. It's not a repair after injurie. I also hope for progress in human eye medecine.
If it happens to humans, we all could look forward to relaxing the high power laser laws (pun intended).
Thought we'd have replaceable eyes, teeth, hair, etc by now. When your vision goes, instead of getting new contacts or glasses, just replace your eyes with a new pair. You have cavities, just replace your tooth with another. The promise of genetic sequencing and research just hasn't panned out.
