Today contact lenses are used by a majority of the world's population. Contact lenses occur in a wide variety of colors, types and textures. If one has to make the right choice while buying contact lenses, some background information will be required to make the right choice.
Types of Contact Lenses
There are two types of contact lenses - hard contact lenses and soft contact lenses.
Hard Contact Lenses
These are mostly made of a hard plastic called polymethylmethacrylate (PMMA). They are also called "gas permeable" contact lenses as they allow oxygen to pass through their surface. These kind of lenses are rarely used unless under prescription.
Soft Contact Lenses
These lenses are made of a soft plastic called "silicon hydrogel". This is a water based plastic, and this type of lens is one of the most widely used today.
