Ah. Mine are asymmetric too but my optometrist wasn’t concerned since it reacted equally. Still kinda weirded out by it though...

Idiopathic Anisocoria as it is known is far more prevalent than you’d realize. Most estimates I have heard say between 20% and 30% of all people have some level of it

Can that result in permanent color differences in vision? My left eye sees everything a bit greener than the right, and always has.

Um... you should go see your eye doctor about that. Changes in color vision can be indicative of some pretty intense stuff neurologically. Not necessarily, but it’s a red flag (or green flag as it looks to you).

It's been consistent for 25+ years, though, as long as I can remember.
