Contact Lenses in Duncan, BC
Toric, Multifocal and Daily Contact Lenses
Today’s contact lenses offering flexibility, convenience, and a “look mom, no-glasses!” appearance while correcting a variety of vision disorders, including nearsightedness, farsightedness, astigmatism, as well for near reading problems.
But contact lenses also present potential risks. Since they are worn directly on your eyes, there is the potential for serous eye infections and corneal ulcers (sores) if you don’t care for the lenses properly—and if you don’t wear them properly. In rare cases, these conditions can lead to blindness.
Contact lenses and certain contact lens care products are registered as medical devices. Best strategies for reducing your risk of infection involve proper hygiene; following recommended wearing schedules; using proper lens care practices for cleaning, disinfecting and storing your lenses (which includes reading and following all product labeling instructions); and having routine eye exams.
By following the right steps, you too may enjoy the freedom contact lenses can provide your lifestyle needs today.
Types of Contact Lenses
In general, contact lenses can be divided into 2 major groups
Soft contact lenses. These are made of flexible plastics that allow oxygen to pass through to the cornea. Users get used to wearing them within several days. Today, most soft-contact wearers are prescribed with some type of frequent replacement schedule, varying from daily , weekly, biweekly or monthly.
Rigid gas permeable (RGP) lenses. While far less common today, these products are durable, resist deposit buildup, and generally allow for clear, crisp vision. While adapting to comfort may take longer than with soft lenses, gas permeable lenses last much longer than soft contacts ( 2-3+ years if well-cared for) and are also easier to handle and less likely to tear.
- Extended wear contacts. These are good for overnight or continuous wear ranging from one to six nights, or up to 30 days. It’s important for your eyes to have a rest without lenses for at least one night following each scheduled removal.
- Disposable (or “replacement schedule”) contacts. Typically, “disposable” means used once and discarded. With a true daily-wear disposable schedule, a brand new pair of lenses is used each day. Often, soft contacts referred to as “disposable” are actually daily wear lenses that, depending on the type can be worn for 1, 2 or up to 30 days before being discarded. It is important to adhere to the approved wearing schedule of the type of lens that you are using. ‘Over- wear’ results in using a lens that is no longer providing the adequate amount of oxygen to your eye leading to increased
- Decorative contact lenses ( also called “fashion,” or “costume” contacts). On July 16, 2016, Health Canada announced that decorative contact lenses will be regulated as Class II medical devices in Canada. This regulatory change aligns decorative contact lenses with traditional contact lenses, which are already regulated as medical devices. All types of contact lenses have associated risks, including:
• cuts or scratches on the top layer of the eyeball (corneal abrasions) • allergic reactions (e.g., itchy, watery, red eyes) • vision impairment • infections • blindness Historically there has been many ‘horror stories’ about the serious complications (including eye infection and blindness) associated with wearing these lenses without a prescription and the appropriate professional involvement.
