So, it looks like vision care emergencies aren't covered, here, in Ontario, Canada, unless you have one of a short list of already existing optical conditions.
Fuck. ;.;
We get a regular checkup covered every two years, and my next scheduled regular checkup is in April, but I don't NEED a REGULAR checkup, I need emergency care for my suddenly reduced vision!
I guess I just have to eat the cost. $85 is a lot for me, but I'm not gonna starve. :/
