Which Stooge if any, could fix Chiaki’s eyes so she didn’t need glasses? Would Chiaki be willing to have her eyes fixed (and then maybe wear non-prescription glasses)? Considering she has wings now, glasses (or flight goggles) might be useful to avoid getting bugs in her eyes at supersonic speeds.

I think any of the stooges can do it easily. The question is if Chiaki is willing to have them fixed. It's always been my belief that she never got them really fixed because she wants to have a link to how she was back then, even if it's something detrimental to her performance.
