A couple of years ago I had cataract surgery for my left eye - which means your lens is replaced with a synthetic implant. It worked great, but afterwards, things in that eye were bluer. The opthalmologist said yes, that's because the synthetic lens lets more through at that end of the spectrum. But the difference only lasted a few days (maybe a couple of weeks). Apparently, your brain can do the equivalent of white balance calibration. How cool is that?
This year I had the right eye repaired, and went through something similar, but it didn't even last as long as it did the first time, probably because both eyes now have identical hardware.
