They are often composed of various types of polymers and contain some variant of silicone hydrogel. Hydrogel is water soluble. This property makes them flexible, act like the human tissue.
Previously, hard contact lenses were made of a polymer known as PMMA, or Polymethyl methacrylate. They have since been replaced by rigid gas-permeable (RGP) contact lenses. Today many contact lenses are made of hydrophilic, or 'water absorbing' materials. This allows oxygen to reach the cornea, and make the lens comfortable to use.

In addition to the convenience, many people wear contact lenses because they think that they appear more attractive if they aren't wearing eye glasses.
