An enhancement tint is a solid (but translucent) tint that's a bit darker than a visibility tint and does affect eye color. As the name implies, it's meant to enhance the existing color of your eyes. These types of tints are usually best used by people who have light colored eyes and want to make their eye color more intense.

Color tints are deeper, opaque tints that can dramatically change your eye color. They are usually are made of patterns of solid colors. If you have dark eyes, you'll need this type of colored lens to change your eye color — at least temporarily. Color contacts come in a wide variety of colors, including hazel, green, blue, violet, amethyst and gray.
