Colored contact lenses can be fun. You have a great opportunity to experiment with different looks. There are also some practical advantages of wearing colored contact lenses. For example, it is easier to find the contacts if you drop them, because they are tinted.
There are four types of colored contact lenses: visibility tints, enhancement tints, opaque color tints and light-filtering tints. Many of these colored contacts are available in a form without visual correction, as well as they can be used by people who have astigmatism, who need bifocal correction, or who want a disposable or frequent replacement lens.
Usually a lens is tinted with a light blue or green color, solely to help you see it better during insertion and removal — or if you drop it. It does not affect eye color, since it's a very light tint.
An enhancement tint is a solid (but translucent) tint. It is a little bit darker than a visibility tint and affects eye color. As the name implies, it's meant that the existing color of your eyes is enhanced. People who have light colored eyes and want to make their eye color more intense usually use these types of tints.
Color tints are deeper; the use of opaque tints can help to change your eye color dramatically. Usually they are made of patterns of solid colors. Dark eyed people using these contacts can temporarily change their eye color. There are a wide variety of colors, including hazel, green, blue, violet, amethyst and gray. You can choose some to your taste.
The companies that make colored contact lenses try to imitate the natural look of the colored part of the eye. Some colored contacts have a series of tiny colored dots to be more natural on the eye. The center of the lens, the part over your pupil, is clear so you can see.
Costume or theatrical lenses are also in the category of opaque color tints. They have been used in the movies for special eye effects for a long time. Nowadays every person, who wants to transform himself into an alien or jaguar, can wear these lenses.
Light-filtering tints are a more recent development. These contact lenses are designed for sports use, because they enhance certain colors (such as optic yellow, the color of tennis balls and some softballs and golf balls), as a result of muting other colors. The result is that the ball stands out against the background and is easier to target. The lenses can also be used by spectators.
One type of light-filtering contact lens has been developed especially for golfers, so they can better distinguish between the various greens on a golf course. Amber-tinted contacts were introduced in the summer of 2005; called MaxSight, they are being worn by some professional baseball players, who find out that they help to see the baseball clearly. Before the appearance of these lenses it was rather difficult, because the blue light reduced their ability to see the baseball good enough. (MaxSight is also available in green-gray for golfers.)
It's important to know that sometimes the colored portion may slide somewhat over the pupil, for example, during blinking.
Also, the size of your pupil is constantly changing in accordance to the accommodation a degree of light. So sometimes, when it’s dark enough, your pupil may be larger than the clear center of the lens. In this case, your vision may be slightly affected.
Remember, if you have a constant problem with your contact lenses, it's important to see your eye doctor.
According to the law you need a prescription. It is needed even if you wear contacts just for changing your eye color and your lenses don't have any vision correction in them (called "plano" lenses). Before November 2005 the government has classified Plano decorative contact lenses as cosmetic items rather than medical ones. But in November 2005 that all changed.
Today, colored contact lenses are mostly used for changing your appearance. As the old saying goes, 'Eyes are the window to the soul'. With just a pair of colored contact lenses, you have a great opportunity to change your appearance with a pair of charming eyes. Therefore,be careful with the estimation of the influence, which a pair of colored contact lenses can really have. Today, colored contact lenses are also can be used by people with astigmatism and presbyopia problem and not only used for cosmetic reason.
