A few days ago I accidentally got some raid max spray in my eye I think. I did not flush out because I did not think any got in my eye. Now my side of my eye is red and looks veiny. Also there's some discomfort. What should I do? Is there any medicines I can take, do I just flush out my eye? I did flush out last night for 5 minutes but it still is red and discomforting

Did you READ the can? Besides flushing it they flat out tell you to seek medical attention.

Is your eyesight that unimportant to you, that you would take the chance to save a few bucks?

Smoothy is correct. You need to see a physician, and as quickly as possible. This is not an emergency, but get to the Doctor as quickly as you can. The pesticide in the spray has some minimal neurologic effects, but the petroleum product solvents can cause blindness in a very very short time.
