I never caught this the first time around. I know alot about the eyeballs (unfortunately) and could have saved you some trouble. I had a similar experience with smashbox/bare minerals mix up.
Anyway after you are done with your prescription eye drops if you ever start having problems with your eyes being irritated again try Systane eye drops. Its one of the best (the best according to my retina specialist) eye drop on the market. Its' got a silky feel to it and helps to keep your eyes happy.
It's super easy to accidentally irritate your eye with makeup, an applicator, or whatever and just as easy to ignore it. So just be careful with the make up.
Good luck and I hope your eye balls start feeling better soon!!!!
