Red light therapy shows promise in triggering pathways that can help rescue vision.

“There's some really interesting data now on the use of red light to try and trigger these pathways. - I saw that study, like 2020, was it? - Now, they have a second study. - Oh, do they? They've done, okay. - It's looking real. - [Rhonda] That's exciting. - I mean, they're cautious. They're appropriately British and cautious about it. I always joke if those studies had been done over here, everyone would already know about it. Glen is a very conservative guy, but they've done this stuff now in pigs, in rodent models, and now also two studies in humans. It's looking pretty interesting.”
