Many people assume that they can buy contact lense from any available source and put them on. But what a lot of people do not know is that contact lenses require a prescription because they are considered medical devices. If contact lenses are not accurately prescribed or properly fitted, it could result in discomfort and injury to the eyes.

If you are interested in wearing contact lenses, you should understand that there is an exam meant specifically to fit you with safe, reliable contact lenses - a contact lense exam. It differs from a routine eye exam in that during a routine eye exam, the doctor will check for your overall eye health and depending on the need, may write you a prescription for eyeglasses.

With a contact lense exam, you will need some extra time and additional tests such as an evaluation of your eye's cornea or surface using a biomicroscope, which will allow the doctor to observe alignment of the lens as it rests on the surface of your eye. The doctor will also take a measurement of your eye's surface and curvature to help your eye doctor determine the proper curve and size for your contact lenses. To help achieve proper sizing and orientation of your contact lense, pupil and iris mesurements are also taken during a contact lense exam along with tear film evaluation to determine your eye's moisture content.

After finding a contact lense that fits properly by means of a thorough contact lense exam, your eye doctor will write a contact lens prescription. This prescription will indicate contact lens power and diameter. Acuvue contact lense is a brand that you can consider when choosing the right contact lense. They have products for different eye conditions like astigmatism, nearsightedness or farsightednes. The contact lense prices may vary according to the type of your vision problem, lifestyle and budget.

So before you decide to wear contact lenses, have a thorough eye exam and contact lense exam by an experienced professional. Of course, follow-ups are as important as the exam itself to monitor any changes to your vision and update your prescription. If you have been wearing contact lenses on a regular basis, see your doctor annually for an eye exam and contact lense exam and more often if you are suffering from any vision problems.
