If you're not totally happy with the eyes you were born with, non-prescription colored contacts can let you create a new pair. You can add subtle changes to your present eye color or get a entirely new color. And because non-prescription colored contacts don't have vision correction, you can change your eyes without affecting your sight.

Non-prescription colored contacts are also known as cosmetic contacts because they're used strictly for appearance purposes. And although they're called "non-prescription", all contact lenses sold in the United States require a prescription. If contact lenses don't fit properly, they can pose a health risk. So a prescription is necessary to ensure a good fit.

If you have light colored eyes, you have the most options available for non-prescription colored contacts. If you want to keep your natural eye color but improve it, there are various lenses that can add small accents. This type of enhancement contact lens doesn't work for dark colored eyes because the color variation is slight and wouldn't show with dark colors.

Both dark and light eyes can change color with opaque non-prescription colored contacts. Opaque lenses have a clear center and a surrounding band of non-transparent color. The lenses can either be a single color or a combination of different shades to give the most natural effect.

Just as taking medications requires a certain schedule, so do non-prescription colored contacts. Every contact lens has a recommended wearing and replacement period that should be followed unless modified by your eyecare provider. To avoid infections and other problems, contact lenses need to be cleaned and disinfected whenever they're removed. If you want to eliminate cleaning, you can get disposable lenses which get thrown away after one use.
