I love outrageous colored contacts, especially the ones that are super vibrant!
These contacts are purchased from Pinkyparadise, if anyone is interested, the direct link to these circle lens are here.
These ones are called: Dolly Eye Grey
These are so vibrant that you can see them in very very dim light, it completely covered my natural eye color and it's awesome for Halloween! Haha. The only down side to this is that it's not for everyday wear, unless you don't mind scarring people on a daily basis. It was also not very comfortable on me. I had to take them off within 4 hours because they were very drying, even after i put eye drops in. It may be different for others but i think my eyes are always on the dryer side.
