|If you are thinking of getting contact lenses, chances are you want to
get away from the glasses look, fogging from temperature changes, or
you're tired of the way glasses can sometimes interfere with sports and
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 must visit an optometrist. 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. Ordering contact lenses online is not safe, even with a
prescription, as different lenses will "fit" your eyes differently and
can greatly impact your eye health. It's important to see your
optometrist so he/she can ensure they fit properly.
There are two main types of contact lenses.
- Hard contacts or Rigid Gas Permeable lenses 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 is essential for healthy contact lens wear. It is also important that you - the patient - learn and follow all instructions on wearing and caring for your lenses.
Ask your optometrist if contacts are right for you.
