CONTACT LENS OVERVIEW

The first step to getting contact lenses is to consult your optometrist. This is necessary even in cases where a patient would like non-corrective lenses (i.e. to change eye color). Contact lenses can only be purchased legally with a valid written prescription by a specialist. Contact lenses are considered to be medical devices wich require proper fitting, which only a qualified eyecare practitioner can provide.

CHOOSING A TYPE OF LENS FOR YOU
There are two major types of contact lenses to choose from: Soft contacts or gas permeable (RGP or GP lenses). The cost associated with gas permeable lenses is initially higher but for some can offer more crisp vision and are resistant to deposit buildup. They take longer to adapt to, however last longer than soft lenses. Soft contact lenses contain water (ranging from 25% to 79%) and can be adapted to quickly.
