For many people, contact lenses provide optimal convenience and satisfying vision correction. Here is what is involved in a typical contact lenses fitting:
A comprehensive eye exam comes first, before being fitted with contact lenses. In this exam, your eye doctor determines your prescription for corrective lenses (which is just your eye glass prescription at this point) and checks for any heath problems or other issues that may interfere with successful contact lens wear. If everything looks okay during your exam, the next step is a contact lens fitting.
Contact lens measurements are done for the same reason that all shoe sizes doesn't fit all feet one contact lenses design doesn't fit all eyes. If the curvature of a contact lens is too flat or too steep for your eye shape, you may experience discomfort or even damage to your eye. Measurements will be taken to determine the best contact lens size and design for your eyes.
Your contact lens fitting may involve one or a number of follow-up visits. The doctor will be able to confirm the lenses are fitting your eyes properly and that your eyes are able to tolerate contact lens wear. Diagnostic lenses in many cases will be used to verify contact lens selection. Often your doctor will be able to see warning signs before you are aware a problem with your contact lens wear is developing. If such warning signs are evident in your follow-up visits, a number of things maybe recommended, including a different fit or a different lens material. Also, using a different lens care method, or adjusting your contact lens wearing time will be considered. In occasional cases, it maybe necessary to discontinue contact lens wearing altogether.
Your contact lens prescription is determined after finding a contact lens that fits you properly, comfortably, and provides good vision for you. Then your doctor will be able to write a contact lens prescription for you. This prescription will designate the contact lens power, the curvature of the lens (called the base cure), the lens diameter, and the lens name manufacturer. In the case of Gas Permeable contact lenses, additional specifications may also be included.
Routine contact lens exams should be performed at least once a year, regardless of how often or long you have been wearing your contact lenses. The yearly exam is to make sure your eyes are continuing to tolerate contact lens wear and show no signs of ill effects from the lenses.
