Yes, if your lenses are going to be used for vision correction – you’d get a
prescription just as you would for “normal,” clear contacts. If you’re using
them solely for aesthetic purposes, not for corrective vision (nonprescription
lenses are called “plano” lenses)
the laws vary from state to state. Regardless of whether or not your colored
contacts require a prescription, it’s still a good idea to buy them from an
optometrist or reputable contact lens company. Some unfortunate buyers of
over-the-counter and flea-market contacts have been the victims of eye problems
resulting from poor labeling and improper fitting. You’ll need a regular
consultation with an eye doctor to ensure you’re getting safe lenses, a proper
fit, and appropriate care and cleaning instructions.
Choosing a color …
Your choice of color will largely depend on how often you’ll be wearing your
lenses – you may want a more natural color if you’ll be wearing them daily, and
a more striking look if they’re for a special occasion – and what effect you’re
going for. If you want a natural look, choose a lens that either enhances your
current eye color or one that coordinates with your natural eye, hair, and skin
tones. For example, if you’re naturally a fair-skinned, blue-eyed blonde, dark
brown contacts may not be the best look for you. Try a deeper blue or green.
Conversely, if you’re dark eyed, changing to a lighter hue won’t be advisable
if you’re trying to be subtle. But if you want to stand out and make a more
noticeable change, go for a shade that is much different than your natural
color. Or choose an eye color that doesn’t normally occur in nature, such as
violet. Also keep in mind the colors of makeup that you usually wear and choose
a shade that will stand out from those colors.
With the vast array of available colors and styles and the relative
affordability of such lenses, changing your eye color is as easy as changing
your shoes. See the world through a different color!
