How Do Colored Contact Lenses Work?
By Steve Cogger
The ability to change your eye color simply by
putting on a contact lens is becoming more popular
every day. Many people like them for fun and never
really care how colored contact lenses work. If
you are a little more inquisitive, read on and I
will tell you exactly how colored contact lenses
The concept of colored contact lenses is to cover
the iris with a new color. In general, neat
colored contact lenses come in two varieties;
opaque colors and enhancement tints. Both designs
work well depending on the iris color they are
covering. One amazing feature of colored lenses is
that they never look exactly the same on one
person as they do on another.
Opaque lenses are intended to change an eye’s
color entirely. Opaque lenses can be used to
change a green eye blue or brown eye green. They
usually have a clear pupil opening in the center
of the lens and a heavy color over the iris area.
Depending on the style of lens and the color
chosen, texture and tint of color will vary. For
example, an Acuvue 2 opaque blue is very different
from a Freshlook blue.
Color enhancer contact lenses are used to boost an
existing eye color or slightly alter its tint.
Enhancers have a light tint which will vary from
covering the entire lens, to simply covering the
outer edge of the iris. A sea green enhancer put
on top of a green eye will give a bright green and
very natural effect. That same lens put on a brown
eye will probably have no effect to the original
A new concept in eye color enhancement is the
equinox lens. This lens simply has a black ring
around the outside of the iris. This simple
feature adds a mesmerizing effect to anyone’s
existing eye color and usually looks completely
Colored lenses are designed to be a fun accessory.
Change your eye color based on your mood, outfit,
makeup, or plans. Regardless of how much fun you
are having with them, remember they need to be fit
to your eyes and proper care must be taken. Follow
your eye care provider’s advice as to which lenses
will work for you and how to care for them
