    • Evaluation and Fitting of Contact Lenses

    • Contact lens technology has evolved rapidly and with today's variety of contact lenses, there are lenses for just about everyone. Switching from eyeglasses to contact lenses begins with an eye exam for contact lenses. After the contact lens exam comes a separate contact lens fitting session.

      Start with the Eye Exam for Contact Lenses

      Before anything else, you should have a comprehensive eye exam for contact lenses. During this contact lens exam, your eye doctor will check your vision and write a prescription for corrective lenses. This is the same type of prescription you would get for eyeglasses. He or she will also check for any eye health problems or other issues that may cause problems with contact lens wear.

      After the contact lens exam, the next step is a contact lens consultation and contact lens fitting.

      The Contact Lens Fitting

      With so many contact lens choices, the first part of the consultation is a discussion with your eye doctor about your lifestyle and preferences regarding contact lenses. One choice that today's contact lenses allow you to make is whether you want to change your eye color. Different eye colors are available with contact lenses. Other options include whether you want contact lenses that are designed to be replaced daily or those which can be worn for more extended periods. Most people choose soft contact lenses for their ease and comfort. However, there are also advantages of hard or what are called rigid gas permeable (GP) lenses. All the specifics will be discussed prior to your contact lens fitting.

      Believe it or not, if you need bifocals, you can even opt for multifocal contact lenses or monovision (a prescribing technique where one contact lens corrects your distance vision and the other lens corrects your near vision). Once you have determined the type of contacts you want, the next step is the actual contact lens fitting.

      Taking Measurements During the Contact Lens Fitting

      While it may not be apparent, our eyes come in different sizes, and one contact lens size doesn't fit all eyes. If the curvature of a contact lens is too flat or too steep for your eye's shape, it could lead to discomfort or even damage to your eye. Your eye doctor will take measurements and determine the best contact lens size and design for your eyes. Here are some of the ways he or she will measure your eyes:

      A Contact Lens Fitting Usually Results in Trial Lenses

      No matter how comprehensive the eye exam for contact lenses, most eye doctors will give you a set of trial lenses just to confirm that they are the right choice for your eyes. With lenses in place, your doctor will use the slit lamp to evaluate the position and movement of the lenses as you blink and look in different directions. You will also be asked how the lenses feel.

      Most people wear trial lenses for at least 15 minutes so that any initial excess tearing of the eye stops, and your tear film stabilizes. Then, you will learn about how to care for your lenses and how long to wear them. You will also receive training on how to put in and take out your new lenses. While it may seem difficult at first, most people quickly learn how to use contacts lenses.

      Follow-Up Contact Lens Eye Exams

      Your doctor may schedule a follow-up visit so he can confirm the lenses you chose are fitting your eyes properly and that your eyes are able to tolerate contact lens wear. A dye may be used to see if the lenses are causing damage to your cornea or making your eyes become too dry.

      It is rare these days that contact lenses cause problems. But, with a follow up contact lens eye exam, your doctor will be able to detect any issues before they become big problems. Most problems that occur can be rectified by things such as trying different lenses or lens material, using a different lens care method, or adjusting your contact lens wearing time.

      Your Next Contact Lens Exam

      Even if the lenses are working fine, you should schedule a contact lens exam at least once a year to make sure your eyes are continuing to tolerate contact lens wear and show no signs of ill effects from the lenses.
