They're hip and they're fun, but colored contact lenses can also be quite practical. There are four types of colored contact lenses, each offering a slightly different benefit:

• Visibility tint. These colored contact lenses are lightly tinted so you can find your lens if you drop it. Visibility tints don't affect the color of your eyes.
• Enhancement tint. These colored contact lenses have a translucent tint that's meant to enhance your natural eye color. Enhancement tints are slightly darker than a visibility tint.
• Color tint. Darker, opaque tints that change the color of your eyes. Color tints come in a wide array of specialty colors, including amethyst, violet and green. The center of this colored contact lens is clear so you can see.
• Light-Filtering tint. These colored contact lenses are designed for athletes and sports fans. They enhance certain colors and mute others to make balls stand out. For instance contact lenses for tennis players would enhance optic yellow, the color of tennis balls.

Remember, never share colored contacts lenses with anyone. Clean and care for them just as you would any prescription contact lens.
