Most colored contacts lenses are designed to mimic the natural look of the colored part of the eye, called the iris.
Since this area is made up of colorful shapes and lines, some color contacts feature a series of tiny colored dots and radially arranged colored lines and shapes to help the lenses look more natural on the eye.
The center of the lens, the part that lies over your pupil, is clear so you can see.
Color contacts come in three kinds of tints:
- Visibility tint. This usually is a light blue or green tint added to a lens, just to help you see it better during insertion and removal, or if you drop it. Visibility tints are relatively faint and do not affect your eye color.
- Enhancement tint. This is a solid but translucent (see-through) tint that is a little darker than a visibility tint. As the name implies, an enhancement tint is meant to enhance the natural color of your eyes. Colored contacts with this type of tint usually are best for people who have light-colored eyes and want to make their eye color more intense.
- Opaque tint. This is a non-transparent tint that can change your eye color completely. If you have dark eyes, you’ll need this type of color contact lens to change your eye color.
Color contacts with opaque tints come in a wide variety of colors, including hazel, green, blue, violet, amethyst, brown and gray.
Costume or theatrical contact lenses also fall into the category of opaque color tints. Long used in the movies (examples are The Man Who Fell to Earth, Avatar and the Twilight series), these special-effect contact lenses are now widely available for novelty use.
You can temporarily transform yourself into an alien, gothic or vampire, to name a few. You can even wear the same type of contacts used in Twilight!
