I have almost only good things to say about these contacts. I have brown eyes, so it can be hard to find a light colored contact that are bright and vivid and these are that! But, in spite of - or maybe even because of - the glimmer they are surprisingly natural looking (for a striking eye). I say this because so many people think this is my real eye color and compliment me on it. Many of my current friends only see me in environments where I’m wearing the contacts, and believe it’s my natural color; they are confused if they meet me outside of costume with brown eyes and say they thought I had green eyes! Honestly, I wasn’t expecting that at all! I assumed they would look a bit cartoonish, which was fine with me, but I’m even happier that people mistake them for my natural color! I can wear them all day without problems as long as I take proper care of them and my eye; but I do keep my contact case around because my eyes can grow weary of them after a long few days (taking them out at night of course), but that may just be me. Overall though, I think they’re very comfortable for costume contacts and I’m very happy with them; I’ve worn them for a year and have had no dangers to my eye or loss of vision to which I’m aware (in case you were worried if they’re “safe” they seem so to me). I’m buying two more pairs in different colors today!
