Contact Lenses

What are Contact lenses?

A contact lens is a thin piece of material that is placed on the front surface of the eye, or the cornea to correct vision or for therapeutic purposes. Contact lenses are considered to be medical devices, and they are used by millions of people worldwide.

For many individuals, contact lenses are chosen to provide a cosmetic alternative to glasses. Others find that contact lenses are beneficial for functional purposes. For example, contact lenses typically provide better peripheral vision when compared with glasses, especially for those who have higher prescriptions, and they do not collect moisture when outdoors the way spectacle lenses do. Additionally, contact lenses provide more flexibility for individuals who want to wear sunglasses or goggles without fitting them with prescription lenses. For these reasons, contact lenses are a great choice for sports and outdoor activities. In addition, contact lenses are often a successful solution for those suffering from keratoconus, or from the effects of corneal injuries or imperfections, since they provide better vision for these individuals than glasses.

What should I do if I am interested in Contact Lenses?

Whether you are new to contact lenses and want to try them for the first time, or you already wear them and want to update your contact lens prescription, be sure to let us know when you schedule your appointment. This ensures that your doctor will not only have time to perform your comprehensive eye exam if needed, but also the time to discuss your wishes and preferences, and to perform the additional tests needed for a thorough contact lens fitting or assessment.

What Happens at a Contact Lens Exam?

In addition to the procedures performed during a comprehensive eye exam, a contact lens exam at My Optometrist Calgary involves:

    • A review of your lifestyle and wants and needs with respect to contact lens.
    • A discussion of your contact lens options, for example daily disposable lenses, overnight wear lenses, bifocal or multifocal lenses, coloured lenses, or specialty lenses to address the effects of corneal disease or prior injury.
    • Measurement of the curvature of the cornea in order to select the most appropriate lens for your corneal size and shape.
    • Measurements of your pupil and iris size to ensure proper contact lens selection.
    • Evaluation of your tear film.
    • Assessment of the contact lens fit and vision through the contact lens.

If it is your first time trying contact lenses, or if you are trying a new lens, you may be asked to try your lenses for a few days to see how they work for your daily activities, and to schedule a follow-up appointment. If you have never worn contact lenses before, we will teach you how to safely insert and remove your lenses, and how to properly take care of them before you leave. At subsequent appointments, your experience in the contact lenses will be reviewed, the vision through the contact lens and the fit will be re-assessed, and the health of corneal surface will be evaluated. Once contact lenses have been selected that fit properly, provide clear vision, are comfortable for you to wear and successfully insert and remove, your optometrist can complete your contact lens prescription.

How often should I have a Contact Lens Exam?

If you are having difficulty with the vision or comfort in your contact lenses, please contact us to have the fit of your contact lenses and eye health assessed. Otherwise, we recommend annual comprehensive exams for our contact lens patients. Routine examinations allow us to regularly monitor the health of your eyes, and ensure that you are in the right contact lenses for your vision, lifestyle, and eye health.
