Dispensing contact lenses

If you are thinking of getting contact lenses, chances are it's because you just want to get away from the glasses look, the fogging that happens from temperature changes, perspiration, or weather, or you're tired of the way glasses can sometimes interfere with sports and other activities. Well, before you decide to join the ranks of millions of Canadians who wear contact lenses, here are some important facts you should know.

First, you need a thorough eye examination by your optometrist in order for your contact lenses to be properly prescribed and fitted. You and your eye doctor can then decide on what type of contact lenses should be worn based on your vision problems, history, occupational and recreational requirements, and other factors.

As for the contacts themselves, there are two main types. There are rigid gas permeable hard lenses and soft contact lenses. Hard contacts are made of a rigid plastic and can correct most vision problems. Although more durable than soft contact lenses, they require an adaptation period. Soft contact lenses are made of a flexible, water-absorbing plastic that conforms closely to the eye. Compared to the hard lenses, soft contact lens wearers need a shorter adaptation period. These lenses are also difficult to dislodge even in sports situations. And, now, there are disposable soft contact lenses, which are worn daily for a period of time and then thrown away. Other special types of contact lenses include tinted or coloured soft contacts, lenses for people with astigmatism, bifocal lenses and contacts with built-in protection from harmful UV radiation.

Your success with contact lenses is based on two main components: the knowledge and ability of the professional responsible for the eye examination and in the contact lens fitting. It is also important that you - the patient - learn and follow all instructions on wearing and caring for your lenses.

Ask your eye care professional if contacts are right for you.
