Ask an Eye Doctor and Get an Answer ASAP
Hello and thank you for your question.
What I would suggest is flushing your eyes out with water for several minutes. Then use some preservative free artificial tears at least every 30 minutes for the next several hours. Cool compresses can help you feel better. Of paramount importance, however, is to stay out of the contact lenses for right now.
As far as your recourse for seeing an eye professional right now, unless you are an existing patient of ophthalmologist or optometrist in that area (which is unlikely since you're visiting) (in which case you should be able to call their clinic # XXXXX talk to the on-call doctor), you'll only be able to go to an urgent care clinic or an emergency room for right now.
I would say if your vision is only slightly foggy and not significantly changed and these treatments I've suggested are helping, then you may be able to wait until the morning. If the vision is significantly affected, the pain is severe, or if anything else is significantly concerning you, then seek one of these avenues tonight.
