Thank you so very much for your answer.

My blind eye follows my working eye, but is noticeably smaller due to its misuse. So you’re probably right on the money there.

I’m a healthy and active nonsmoker, and intend to remain so! I suppose the dream of magically seeing with my right eye has never been more than that, but I can’t help be a tiny bit hopeful when I see news like this.

Not a doctor but I don’t think that’s the case for sure, depending on the diagnosis. If it was some type of heart defect, likely yes. If it was the impact stopping his heart, that’s more of a freak incident (how many times had that happening in the NFL in the past 25 years?). I don’t know if having it happen once increases the likelihood of it reoccurring, but it’s not like a knee or neck/back injury that impacts your ability to move on the field. It’s not unreasonable to think a 24 y.o. professional athlete has a reasonable chance of playing again (assuming that they aren’t at a risk for reoccurrence. At the same time, no one would blame him for walking away either.

Short answer is that it's not possible.

Long answer, most likely, the muscles are weak and imbalanced from disuse, so you might not be able to point your eye in the right direction to even begin making connections. If all of the biology is OK, then some connections can (possibly) be made, but 1 million to 1 odds, you'll never ever be anywhere close to happy with the vision.

You'd have to cover the good eye, and go through life using only the blind eye, likely for years. Learn to feel things while looking at them, and hope that your brain makes the right connections between specks of light and the physical form in your hands. You might get to the point where you can see that you're holding a vague oblong mass, and guess that it's a fork because it feels like one. That would be considered a success by current standards. At best, that eye might help you fumble your way around the world, slightly better and safer than being blind. But reading, recognizing faces, probably never.

Protect your good eye. Don't smoke, keep blood pressure/cholesterol down, don't become overweight or diabetic. Avoid getting sick. See your eye doctor regularly. Most importantly, wear some sort of shatterproof eyewear at all times. You don't have "back-up" eye like other people. Be well.

Ho. Lee. FUCK!!!

This is great news! Both my Dad and brother were born with only one fully working eye (They have both eyes, they just can't see out of one).

I started wearing glasses in high school and part of me worries that I'll go blind one day for no reason. It's an unfounded fear, but it's a fear nonetheless.

I love the future!

I had retinal detachment in BOTH eyes and my remaining vision is really not that good. Thanks to the amazing professionals it is still enough to get around and even play most games.

To think that this might be "repairable" in the future is so amazing and uplifting. When it comes to science and medicine we actually live in a very exciting time right now!

Even with these examples, this therapy wouldn't do much. The UV radiation off a torch doesnt typically penetrate deep enough to hurt the retina, just burns the cornea. A severly detached retina results in too much scar tissue to implant anything. Color deficiency.. 1 out of 12 men have it and live a normal life. Cell replacement seems like overkill.
