Despite the fact that color contacts is a fashion statement in modern society, it is a serious consumer choice to purchase it. That is to say, not everyone could buy a pair of color contact lenses in an optical store at his/her wills. Color contact is considered to be a medical device which would only be sold when the buyers provide relative prescription, or eye problems, such as eye infection, eye injury and even a loss of eyesight may resulted in. Therefore, when you are intended to purchase color contacts to enhance charm or to make your eyes bigger and fire eyed, go for an eye doctor first to get an eye examination.

It is necessary for you to know at least one hour or more is needed for you to get the exam, because there are a series of tests, including depth perception, near and distance vision test and glaucoma, etc.. In addition, for your eye health, you could even ask the eye doctor any questions concerned. Never think that your questions are unnecessary or stupid, as one who knows nothing about eye care, all the questions are worthy to be explained. A little tip is to bring a pair of sunglasses when you go for the exam, because the doctor would use some drops, which would make your eyes sensitive to light for a few hours, to dilate the pupils, so that he/she would see the inner structure of the eye.

With careful examination, your eye doctor will tell you whether you are a candidate for color contact lenses. If you are, he/she will give you a prescription, with which you could buy your contact lenses of the color you like. Don’t be surprised if your doctor tell you that you are not recommended to wear color contacts, for they are not suitable for everyone. There are possible risks for those who have eye diseases to use color contact lenses.

Some people, especially teenagers, would hold that they are in a good eye condition, so they do not need to get any eye exam, which seems to be a great trouble. However, just image you put a foreign body into your eyes, and what will happen. Eyes are so fragile. Great harms to eyes are possible. Therefore, it is very important to have an exam done beforehand.

The fact is that, you have to have an eye exam before you wear color contacts. It is also a must when you need any other kinds of contact lenses and corrective glasses.
