I love these contacts. They completely block out the color of your irises and complete any scary costume! I also wore them to my job at a Halloween store, and while I was getting my coffee that morning I got some pretty strange looks. These are definitely too intense to be wearing on a daily basis xD.

I'm not sure if its the black ring around the lens or what, but they completely block out my peripheral vision. Since I wear glasses anyways, I don't focus over there so it didn't bother me. The contacts themselves weren't completely clear either. There was definitely a bit of fog over my eyes for the entire day. You get used to these very quickly. They're a bit uncomfortable at first, so put them in an hour before you go anywhere. After that, they feel great. I wore them all day at work and got tons of compliments. Even though they were a little foggy, I'd buy them again and plan on it! You have to realize that they aren't contacts that have been fitted to your eyes or anything, so there's the chance that for some people they may not be as comfortable.
