Contacts, also known as contacts lenses come in both hard and soft options. Contact lenses typically serve the same corrective purpose as conventional spectacles but are less cumbersome and almost invisible.

They are often composed of various types of polymers and have some variant of silicone hydrogel. Hydrogel is water soluble. This property makes them flexible, act like the human tissue.

In the past, hard contact lenses consisted of a polymer known as PMMA, or Polymethyl methacrylate. They have been replaced by rigid gas-permeable (RGP) contacts. Currently many contact lenses are made of hydrophilic, or 'water absorbing' materials. This allows oxygen to reach the cornea, and make the lens more comfortable to use.

It has been estimated that 125 million people use contacts worldwide. Approximately 35 million people in the United States wear contacts. The types of contacts people are buying vary considerably between countries. Germany, Netherlands and Japan buy select about 80% of the time and about ninety-five percent of the time in Scandinavia.">http://www.shoplens.com/result.asp?SID=B0FCF5F1-7555-4937-B15B-FB868B77A7D1"> Disposable Lenses about 80% of the time and about ninety-five percent of the time in Scandinavia.

In addition to the convenience, many people wear contacts because they think that they appear more attractive if they aren't wearing eye glasses. Contact lenses are easier to replace than eye glasses and don't steam up. Eye glasses can be dangerous when worn while doing some sports and eye glasses don't have the wide field of vision that contacts offer. Some physicians prefer their patients to wear contact lenses for specific vision issue that can't be corrected with eye glasses, such as keratoconus and aniseikonia. Patients with these problems often have better vision when wearing contacts.

Many patients with imperfect vision begin wearing contacts when they reach puberty are about 10 years old. This is a time of life when looks is a serious concern. This is of particular concern for youngsters that are active in sports and programs in which they perform.
