Three types of colored contact lenses

Colored contact lenses are available in toric, bifocal and disposable types. Actually, colored contacts use three types of tints: visibility tint, enhancement tint and color tint. Light blue or green visibility tints are used to make contacts more apparent while you putting them on or removing them off. Unlike a visibility tint, an enhancement tint intensifies your eye color slightly using darker colors. They are solid and meet the need for some people. Color tints are favored by people with dark eyes but want to change their eye color. These deep colors used include hazel, green, blue, violet and grey. Costume or theatrical contacts belong to this type, which always create special effects in novelties and movies by changing the people’s natural eye color. For all these three tint types, natural appearance is the most important code. Some manufacturers even make tiny colored dots on lens without affecting the lens center.

Colored contacts do have disadvantages. For example, the colored part may slide over the pupil while you’re blinking. Furthermore, the changing of pupil size may make the lens center deviate from the eye center, which affects normal vision for sure. Always see your doctor to solve these problems.

Colored contacts must also be regularly cleaned and stored with proper cleaning products. They are medical devices for personal prescriptions. You should never sacrifice your eye health for fun, such as sharing colored contacts, which may probably cause dangerous eye infections.

The US law strictly controls the purchase of colored contacts, even for non-powered ones. The US government ever considered plano contacts as cosmetic devices and required no prescription, but still published warnings against non-prescription contacts because of their potential risks. On November 9th 2005, this situation was changed that all colored contacts and prosthetic contacts were judged as medical devices so that a prescription is a must now. Defying the laws, some illegal vendors still sell non-prescription color contacts in flea markets, gas stations, beauty salons and novelty shops.

The selection of color can be simply determined by your personality. Unless you wear daily disposable colored contacts, you should make a decision on the color. If you like to be noticed and accustomed to be the center among your friends, bright-colored contacts are your choice. Warm-toned colors fit cool skin and hair colors. Violet, green and blue contacts suit brown eyes. If you like natural appearance, the contacts color should be subtle. In this case, enhancement tints are preferred. A blue enhancer may define your iris edges without drastic change. It is similar that gray or green fit blue eyes and hazel suit warm-toned eyes and skin. For an exceptional wearing, most people may choose a contrasting color.
