Avoiding Eye Irratation and Red Eye Symptom Caused by Minoxidil, Can It Change Eye Color As Well?

I am using minoxidil %5 for fighting hair loss. My eyes irritate and become a bit bloody looking after applying it, i am not putting my fingers to my eye, just applying on to the entire scalp. How can i avoid this, is it because of alcohol (part of minoxidil formula) evaporation? Can goggles help prevent it? Also is there any ways minoxidil can change eye color when used on scalp? Thanks.
