Soft contact lenses are available in colors that can change or enhance the color of your eyes in prescription or non prescription. It is important that you get your colored contacts from an Optometrist that can provide you with the right pair and color. It is against the law for anyone other then an eye doctor to prescribe or sell colored contacts.
Colored contact lenses can change the color of your eyes entirely from brown to blue or hazel to grey, for example. Some clients will buy multiple colors in order to have options in matching with their fashion style.
