Contact Lenses

There are three types of contact lenses, classified by the materials they are made from:

Soft lenses – Made from a gel-like, water-containing plastic, these are the most common type of lenses and are slightly larger in size than your cornea.

Hard lenses – Made from rigid plastic called PMMA that does not transmit oxygen to the eye, these lenses have virtually been replaced by GP lenses and are rarely prescribed today.

GP lenses – These are oxygen permeable lenses, meaning they are made from rigid, waterless plastics and are especially good for presbyopia and high astigmatism. GP lenses are smaller in diameter and often provide sharper vision than soft lenses.
