Learn about contact lenses and their types

 Contact lenses are designed to fit over the cornea allowing the person to see clearly through them. They are available in great variety and are more versatile these days. Contact lenses are medical devices so they should be handled with care. Many vision related problems can be easily corrected with lenses such as nearsightedness, farsightedness, astigmatism and presbyopia. They are a good alternative for people who want a relief from eye glasses. Not only for vision correction but also they can be used for cosmetic purposes.

Types of contact lenses

Daily wear soft contact lenses

These lenses are made from soft and flexible plastic. They are the most commonly prescribed contact lenses. The material used in them easily allows the oxygen to pass through them.

Extended wear contact lenses

These contact lenses can be used overnight as well. They are available in both soft and RGP lenses. One of the greatest advantages of these lenses is that they can be worn up to seven days without removal.

Extended wear disposable lenses

Such lenses can be worn for an extended period of one to six days and then need to be discarded.

Rigid gas permeable contact lenses

They are rigid or hard contact lenses and are made from plastics combined with silicon or fluoropolymers. They are known as gas permeable as they can allow the oxygen to pass through the lens easily.
