Color Contact Lenses: Walk on the
Wild Side

The range of available cosmetic lenses today is extensive.
Patients can now change their eye color as often as their
wardrobe or mask ocular disfigurement without calling attention
to their eyes.
There are three distinct types of colored lenses: enhancers,
opaque lenses, and light-filtering tints. These lenses are
available in a variety of prescription types including plano
(lenses without vision correction), spherical and toric
lenses. Even if you intend to purchase plano lenses, you
will still need a current contact lens prescription and
fitting. Color contacts are also available in all wearing
schedules and replacement schedules.

Light-Filtering Tints
These contacts represent the latest development in color
contact lens technology. Light-filtering lenses are primarily
designed for enhancing sports performance and for other
recreational uses. They are tinted in a manner that enhances
certain colors (such as the yellow of a tennis ball) while
muting other extraneous or distracting colors. Because of
this, an object like a tennis ball is viewed in greater
contrast with respect to the background and is therefore
more easily focused upon.
Enhancement Tints
While some handling tints may affect the patient's eye
color slightly, cosmetic or enhancer tints are required
to make a purposeful change in someone's iris color. These
tints are translucent and blend with the underlying iris
color to achieve an enhanced color effect when worn. Since
these lenses are generally created with a light dye uniformly
applied on the front surface, dark-color irises do not blend
well with the lens color and typically eliminate the blending
effect. Light blue and green eyes work best with enhancer
tints; and aqua, blue, royal blue, and green are typically
the most frequently chosen lens colors. The real color enhancement
obtained with these lenses is a combination of the actual
lens color, shade, and intensity of the tint; and specific
lighting conditions. Hence, an aqua lens from one manufacturer
may not look the same as an aqua lens from another, and
the color may vary depending on to the lighting conditions.
Opaque Tints
Opaque tints incorporate opaque dyes throughout the lens
material and result in a color change that is generally
independent of the underlying iris color. They can make
brown eyes appear blue and even mask corneal scars. However,
opaque tints have been reported to reduce peripheral vision,
especially when decentered from the patient's line of sight.
Plano Color Contacts
It started as a fad; now it's 30% of cosmetic contact lens
sales. After contact lens companies discovered there was
a demand for eye color change among people who don't need
vision correction, they started making more sophisticated
products to capitalize on this growing market. First it
was disposable contacts, then opaques, then patterns.
Those who are most intrigued about wearing plano contacts
fall into the teenage to young-adult categories, those whose
appearance often takes the form of a bold statement. This
represents a lowering in age for plano lenses, as the market
previously had been young adults and older.
