Even though you may not need them to correct your vision, if you want colored contact lenses you will have to visit an eye doctor to obtain a prescription. A prescription for contacts that doesn't include vision correction is called a plano prescription. This type of prescription measures the width and the curvature of the eye and will insure that the contact lenses fit properly. If they don't fit right you'll know in a moment because the pain will be persistent and irritating.

Unfortunately, there's a belief among wearers of colored contact lenses that because a pair lacks vision correction it's okay to share the contact lenses with others. This is wrong! Under no circumstances is it ever a good idea to share contact lenses so don't. Not only might they be the wrong size and cause discomfort, if they haven't been cleaned, the other person likely will introduce harmful bacteria into the eyes which can cause irritation and other eye problems.

Within the world of colored contact lenses you'll find many options and it's important to understand what these options are. For example, opaque colored lenses are absolutely necessary when a person wants to completely change eye color. Colored lenses are actually tinted, and besides changing color you'll find other types of tints, some of which aren't necessarily designed to change eye color.

One of the benefits of a visibility tint is that the tint makes the lenses easier to handle by making them easier to see. Clear contacts can end up anywhere when they're dropped and they'll be invisible and nearly impossible to find. But the colored tint on the lens will help pinpoint their location. Enhancement tints have a deeper tint that will enhance and intensify a person's eye color.

Lenses that are coated with UV/UB protection tints are preferred among those who participate in outdoor sports. The tints help to reduce glare which improves vision and hopefully the game. And speaking of sun protection, there is a brand of colored contact lenses that darken to a color that resembles that of sunglass lenses when exposed to light. Once inside, the color transitions back into clear.
