Understanding Contact Lenses

Contact lenses are thin lenses that sit directly on the cornea (the clear outermost layer of the eye). They are vision-corrective devices that are used to correct refractive errors and maintain ocular health.

There are two basic types of contact lenses: soft contact lenses and hard contact lenses or gas-permeable contact lenses. The soft lenses are comfortable, flexible and easy to use which makes them more common. The hard lenses give clearer vision, are less likely to tear, resist lens deposits and are hard to maintain.

If the eye health is suitable to wear contacts, a contact lens fitting will be carried out by the eye care professional. The fitting will include a measurement of the surface of the eye and also the tear production percentage. This will help the eye doctor pick the most suitable lenses.

A pair of trial lenses will be provided for usage for a duration of time. This allows for training on how to put on and take off the lenses and maintain them properly.
