Contact Lenses

Contact lenses have long been the corrective choice for people who prefer not to wear eyeglasses. For particularly active people, eyeglasses may not be the most appropriate solution.

These small plastic lenses require greater responsibility for those who wear them. Your Optometrist can specify for you the precise cleaning and care requirements of your contact lenses. They can also provide a complete fitting and consultation, allowing you to choose between a variety of contact lens styles. The provincial Medical Services Plan (MSP) does not provide coverage for contact lens therapy, although there are some medical exceptions. Your Optometrist will inform you of any charges that may apply to your contact lens-related visits.

Materials

• Soft contact lenses are easy to wear, particularly for the first-time wearer, coming in a range of disposable options from one day to one year—your Optometrist can recommend the best one for you.

• Rigid gas-permeable (RGP) lenses are more durable and may provide sharper vision, but since they are not water permeable, they may be more difficult to wear.

• Ortho-Keratology is a treatment for myopia involving a progression of rigid contacts designed to alter the shape of the cornea and eventually reduce the wearer’s nearsightedness.

Types

• Extended wear lenses can be worn overnight and continuously for up to one month (with the latest lens materials available), but require more attentive care to prevent infection and related extended wear problems

• Disposable lenses are the most common, and are discarded after a specified length of time—reduced cleaning time, costs and healthier eyes are among the benefits.

• Toric lenses are specially curved lenses designed to correct astigmatism [link to Common vision problems > Astigmatism].

• There are a variety of other types, including coloured, novelty and UV-blocking lenses, and lenses for astigmatism and bifocal needs.
