You can find contacts both with and without any type of correction which makes them suitable for everyone. I recall that one of my childhood friends used to change her eye color almost every week. While her natural eye color was brown, she liked to use violet and green colored contacts to make her eyes pop.
There are two major types of colored contacts available. There are opaque lenses which are suitable for those who want to change their eye color completely. On the other hand, if you have light eyes (like myself), and you just want to enhance their color, then tinted lenses might be your best choice. If you've ever wondered what you would look like with a different eye color, colored contacts are a fun and inexpensive way to give yourself a quick mini-makeover. Here are some examples of how much effect colored contact lenses can have.
