Color contact lenses come in a wide variety of shades and tints that are designed to alter or enhance the wearer’s eye color. Those whose eyes are light colored can use semitransparent contacts with an enhancement tint to intensify their natural eye shade. And opaque contact lenses of solid, deep colors can completely transform both light and dark eyes.
There are also contact lenses specially made for costume and theatrics. These lenses are used on actors for special effects. Another type of color contact lens is the ones with light-filtering tints. Light-filtering contacts reduce the glare from the snow and the sun. In addition, these lenses can reduce the brightness of some colors while increase the richness of other colors. Light-filtering contacts are quite popular among professional athletes because the lenses let them narrow their focus on particular details during a game. For instance, the yellow color of a tennis ball will be enhanced; therefore, the player can easily follow the ball during a match.
Although different than clear contacts, any kind of color contact lens must be cared for in the same manner as their clear counterparts. The user need to regularly clean and disinfect them. It is not recommended to use tap water for soaking and cleansing any type of contact lens because of the bacteria contained in the water. In addition, the wearer should never share their color contact lens with anyone. If so, they run the risk of contracting an eye infection or other harmful condition.
In the eye care profession, color lenses that do not correct vision are referred to as “plano.” Even though most people buy a set of color contact lens for cosmetic reasons, a prescription can be applied. In the United States, it is illegal to buy contact lenses without having a valid prescription, which is outlined in the Plano Contact Lens Law of 2005.
