If you wear or decide that you want contacts, you need a contact lens exam in addition to a comprehensive eye exam. Your eye doctor will perform special tests during a contact lens exam to evaluate your vision with contacts. These tests measure your eye surface to determine what size and type of contacts are best for you. Sometimes the doctor may do a tear film evaluation to make sure you can comfortably wear contacts. Once they know the results of your exam, your eye specialists can provide you a proper contact prescription. Any improper fitting or prescription of contacts can damage the health of the eyes.
Some people may think that an eyeglass prescription is and can be used as a substitute for a contact lens exam. However, the two are actually very different. An eyeglass prescription measures for lenses that are positioned away from your eyes; whereas a contact lens prescription measures for lenses that sit directly on the surface of the eye. The improper fitting or prescription of contacts can damage the health of the eyes. Therefore, a contact lens exam is vital to ensure that your eyes stay healthy.
Contact lenses come in a variety of brands and style choices. Once you have decided on the brand, you can now choose if you want extended wear, daily wear, or even color contacts. Your doctor will fit you with a trial pair of contacts and have you wear them for a few days. In about a week, you’ll need a follow-up exam to make sure your eyes have adjusted well to your new lenses.
Whether you wear glasses or contacts, it is a good idea to get a yearly eye exam to see if you have new or existing vision problems and if you need vision correction.
