If you want to go to your county hospital, they will help you. Not all ERs can help with eyes. A county hospital should be able to.
I am not a doctor, but I am an experienced patient with vision damane. If I had put that kind of thing in my eye, I would have gone immediately. Please, you do not understand damaged vision unless you have expereinced it. Please prtect your vision. You can pay the hosptial over time.
Call the poison control center 18002221222, and they can give you feedback. I call them with any question like this. They are helpful. Maybe they can tell you flushing is enough. But I would call twice and talk to two people. It's called double checking.
I hope you are better soon.
