I had this a year or so ago, when I had to have surgery on my eyes and have new artificial lenses put in. They only do it one eye at a time with a long gap in between, and after the first one there was a noticeable difference in colour tone between the two eyes.
Thankfully, once the second one was done, both were back to the same colour tone, but it was a very weird experience having never had it before.
Well, let’s hope it’s nothing trivial.
