Colour Contact Lenses - Corrective, Therapeutic And Cosmetic
Two types of cosmetic lenses are colour 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 essentially change the appearance of the eye.
It is important that a person finds colour that suit their natural features though; otherwise their eyes may look strange.
Some people may require colour 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.
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 are in order. In these cases, an eye patient will mostly likely be
prescribed spherical lenses. Therapeutic cure other problems that are non refractive, like dry eye, and some
types of therapeutic lenses even deliver medicine to the eye.
Prescribed,
corrective colour 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.
