Your dog might be having an allergic reaction to something, either in your house or possibly an insect sting. The vomiting and swollen eyes can be an indicator of that.
If the swelling has gotten better today, I would just keep an eye on her.
If it has not improved, a trip to the vet is in order. With your sudden health crisis I know you might not be able to get her there quickly. If she is blinking/squinting/painful-I'd say don't wait, it might be glaucoma and a true emergency. If she is comfortable, just bug-eyed, it can safely wait.
If she is still vomiting and acting sick, she should be brought in.
I wish you luck with your health problem. I hope you are getting excellent care. Please let me know how your dog does, and I can continue to advise you on this one. I'd like to help. If you have any concerns, please let me know, or call your vet.
