Three types of colored contact lenses
As we know, regular contact lenses are used for vision correction like prescription eyeglasses. They are mainly crystal clear. But there are now available colored contact lenses. Do not make a complex interpretation. These are just contact lenses that have a visible color. These visible contact lenses differ considerably from clear contacts in terms of appearance. Furthermore, these colored lenses also differ in functionality that they are generally for cosmetic or aesthetical purposes, even though optical powers can be applied. From a wider perspective, colored contact lenses are available in toric, bifocal and disposable types.
Three tint types for colored lenses
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 putting them on or removing them off. Unlike a visibility tint, an enhancement tint intensifies your eye color slightly using a darker color. 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 colors. These deep colors include hazel, green, blue, violet and grey. Costume or theatrical contact lenses belong to the third type, which always creates special effects in novelties and movies by changing the people’s natural eye color. For all of these three tint types, achieving a natural appearance is the most important guideline. Some manufacturers even make tiny colored dots on lenses without affecting the lens center.
Colored contacts also require regular care
Colored contacts must also be regularly cleaned and stored with proper cleaning products. It is a must to carry out regular cleaning, rinsing and disinfection, as frequently as required by an eye doctor. They are medical devices according to personal prescriptions. You should never sacrifice your eye health for fun, such as sharing colored contacts, which quite probably cause a dangerous eye infection.
Colored contacts are definitely medical devices
The U.S. laws strictly control the purchase and selling of colored contacts, even for non-powered ones. The U.S. 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 9, 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.
How to choose a color
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 a good choice. Warm-toned colors fit cool skin and hair. Violet, green and blue contacts suit brown eyes. If you like a natural appearance, the contact lens color should be subtle. In this case, enhancement tints are preferred. A blue enhancer may define your iris edges without a drastic change. It is similar that gray or green tint fits blue eyes and hazel tint suits warm-toned eyes and skins. For an exceptional taste, some people may choose a contrasting color.
Colored contacts may be problematic
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.
