Color lenses suit people with
perfect vision as well as people who need vision correction.
You can get prescription
color contacts as well as non-prescription ones.
Most non-prescription cosmetic
color contacts are soft lenses. Most colored lenses
contain 50-55% of water. Higher water percentage isn’t
suitable for coloring the lens. Therefore, you shouldn’t
wear them all day long, regardless of what the advertisement
wants you to believe. And you should never sleep in your
color lenses.
The color can be of two different
types: solid (which looks a bit artificial) or simulating
natural color of an iris of the eye. The second pattern
looks more natural and creates an illusion that your eyes
have always been that bright, beautiful color.
Almost all contact lens manufacturers
produce color
contact lenses now. Most popular color contacts are
Acuvue 2 Colours by Johnson
and Johnson, Expressions by Cooper Vision and Freshlook
by Ciba Vision.
These color lenses are so popular
because not only they create beautiful, natural looking
effect, but they are also very comfortable. All three
brands are frequent replacement color lenses (Acuvue –
2 weeks replacement, Freshlook and Expressions –
monthly replacement lenses). Replacing your contacts often
is always the healthiest choice for your eyes, because
with time protein from your eyes builds up on the lens,
it starts feeling uncomfortable and doesn’t provide
clear vision.

by Ciba vision. Beautiful opaque lens in gray, violet,

Conventional non-prescription
colored contacts are not as comfortable as frequent
replacement ones. They are intended to last for a year,
so they are thicker. They don’t let enough oxygen
through. For this reason you shouldn’t wear them
longer then 8 hours a day. Also with time protein builds
up on a lens and it loses its clarity. Most conventional
color lens wearers report that a “year” lens
usually only lives 8-10 month.
