Contacts can come in a number of varieties, including hard and soft. Hard contacts are typically not disposable, while soft contacts often are. Some soft contacts are also known as extended wear lenses. The most commonly used contact lenses today are of the soft variety, invented in 1961 by the Czech chemist Otto Wichterle (1913-1998). Contact lenses (both soft and hard) are made of various types of polymers, usually containing some variant of silicone hydrogel. Previously, hard contact lenses were made of a polymer known as PMMA. They have since been replaced by rigid gas-permeable (RGP) contact lenses. Many contact lenses are made of hydrophilic (water-absorbing) materials, thereby allowing oxygen to reach the cornea, and make the lens more comfortable to wear. Heavily tinted contacts are tinted to change the color of the iris, and are used for cosmetic reasons. Some standard contact lenses are slightly tinted in order to make them more visible for handling purposes. Color contact lenses are mostly used by teenagers now-a-days to change their looks while attending parties and other special occasions. There are people who want to have a different look and changing the color of their eye gives that changed look. No wonder it gives a stunning look if you choose the right color of the lens so that it matches your body color and hair color. Blue, Grey, Hazel, Turquoise, Aqua, Brown, Green, and Violet are some of the color in which you get the contact lenses. Apart from this there is also cheap crazy contact lens available in the market that changes the looks of your eyes to that of the cat or a dog.
