Article Body:
Prescribed, corrective colour contact lenses are actually more popular
than lenses that are purely cosmetic though; sometimes people prefer
certain tints to help them see their environment better (colorblind
people have had mild success with tinted lenses that make it easier for
them to discern colors), others like to have tinted lenses that can be
found easily when they are dropped on the ground or in the sink, while
still others simply want a new eye color.

Contact lenses are classified as corrective, therapeutic, and cosmetic.
For those who are short sighted, near sighted, or who have astigmatism
(all refractive defects of the eye) corrective contact lenses are in
order. In these cases, an eye patient will mostly likely be prescribed
spherical lenses. Therapeutic contact lenses cure other problems that are
non refractive, like dry eye, and some types of therapeutic lenses even
deliver medicine to the eye.

Two types of cosmetic lenses are colour contact lenses and special
effects contact lenses. While these lenses occasionally correct vision
when needed (they are basically spherical lenses), they also can blur
vision because of their design. Colour contact lenses essentially change
the appearance of the eye.

Some people may require colour contact lenses for less superficial
reasons (perhaps they have a physical deformity on their iris) while
others may simply want to ditch their natural brown eye color for a more
appealing blue. Natural shades like hazel or blue are available but so
are wilder colors like purple. A subtler colour contact lens is the
tinted lens, which enhances one's natural eye color, as opposed to
drastically changing it.

It is important that a person finds colour contact lenses that suit their
natural features though; otherwise their eyes may look strange.
