I have always thought eyes to be one of the sexiest parts on anyone, man or woman. As hokey as it sounds, I do believe eyes can be the window to the soul...or at least, expose a certain vulnerability and truth that can be very sexy.
I have very light blue eyes and dark hair...so I do get a fair amount of compliments on my eyes, and it's always one of the more treasured compliments to receive.
I've known a few people who have worn colored contacts, and I always think it looks silly. Granted, a lot of those people who wore the colored contacts were very tan and wearing blue contacts that just screamed "fake." Blue can be a coveted color because blue is a popular color all around. But I'd much rather see a real pair of dark browns than a fake pair of light blues. My two cents, anyway.
