I also vote that you prioritize getting your eyes checked over "something comes up." In the last five years or so my middle-aged eyes have needed cataract surgery and one eye, terrifyingly suddenly, a detached retina repair.

(If part of your field of vision suddenly goes dark, do not hesitate and do not put it off -- see an eye doctor at once. And yes, this IS worth going to the ER if it's a weekend.)
