Tinted color lenses will not dramatically change the color of dark eyes, but they might give them a different shade, or enhance the natural iris color, perhaps making them appear bluish or greenish. They are better choice for people with lighter colored eyes, when they can affect the color in much more effective way.
Choosing colored contacts for dark eyes requires an eye check-up and the visit to the eye professional, just like when choosing any other type of lenses. They are considered medical devices and by law, only a medical professional can prescribe them. Although it is now possible to buy colored contacts at various flee markets or from private dealers, it is not a good idea. Your eyes are too important to risk them with an untested and unreliable product. Trust your eye professional and make sure that you are getting only the best for your eyes.
When choosing the color for your dark eyes, you might find the choice overwhelming. After all, you can go really crazy and dramatically change the way you look. You have to ask yourself why you are choosing colored lenses in the first place. It will also very much depend on what kind of person you are timid and unassuming, or dramatic and risk-taker. It might be a good idea to bring a friend with you, or to try one of the websites where you can download your photo and try different eye color lenses electronically. It might save you $30, but it will not be as much fun as choosing the colored lenses directly, in the store, in front of the mirror.
When deciding to get colored lenses for your dark eyes, you should be aware of the perceptions people have about the link between the eye color and the intelligence. Majority of people believe that people with brown eyes are more intelligent than people with blue or green eyes. Nonsense, you say? Perhaps, but perceptions and beliefs often matter much more than the facts. Just something to think about, to make your decision to choose colored lenses even more difficult.
