Very true Ephemera, with a blank profile we don't know anything about you. Basic things like how long you've studied and what can help us help you.
Either way, this spell won't change your eye colour. It may create the illusion of your eyes being a different colour, but it will not change them, magick is not like The Craft. If you want hazel eyes so badly, buy contacts, I have a friend who wears purple ones all the time, you can get them in any colour or design. I've seen contacts that make your pupils look like stars, moons, tiny, huge, slit, and basically any shape and colour you can think of.
