What is Contact Lens?
To correct the refractive errors of the eye, it is produced as an alternative to the glasses. It is used for optic purposes to correct visual defects by attaching to the corneal anterior surface. Contact lenses are used for optic purposes, but are also used for cosmetic and therapeutic purposes.
What are Contact Lens Types?
Contact lenses are two groups of hard and soft contact lenses. Hard contact lenses are lenses made of hard material and are smaller in diameter than soft contact lenses. Gas permeable contact lenses called semi-rigid or semi-soft are also a kind of hard lenght. Soft lenses like soft lenses. For the adaptation of hard lenses to the eye, the patient should use such contact lenses more and more every day. Gas-permeable hard lenses are used in eye diseases such as high astigmatism, irregular astigmatism, keratoconus, and the time of acclimation to the lens is approximately 1 month.
In soft contact lenses, they are larger in diameter than hard lenses and they cover the colored part of the eye when they are attached to the eye and overflow into the eye white. A significant difference between hard contact lenses and soft lenses is their maintenance. Soft contact lenses should definitely be kept in a special liquid after being removed. Soft lenses have a high proportion of water in their contents. If they are not present in the liquid environment, they lose water and become dry and deformed. Soft lenses must be stored in a special liquid to reduce the risk of infection. Daily, weekly, monthly lenses, 3-month lenses, 1-year-old lenses used daily, therapeutic lenses used for the treatment of some eye diseases, such as bifocal lenses and colored lenses. Most of the lenses used to correct the defect in the eye are colorless and do not change the appearance when inserted into the eye. They remove the defect and provide a clear picture as long as they are fitted.
Bifocal lenses have been developed for people who have to use two separate glasses for close and distant. A lens group that is very popular nowadays is color lenses. It can be used to correct the defect in the eye, but it has only the numberless types used for aesthetic purposes. Color options are available. Prosthetic Iris Lenses are soft lenses that are used to camouflage aesthetic defects such as an ocular disease or a white spot that occurs as a result of an accident in the cornea, or to change the eye color of people and look more normal.

• In high grade defects, the contact lenses are small in diameter and thickness, as well as reducing the visual disturbances of the peripheral parts due to the fact that they are attached directly to the eye.
• It is difficult for the patient to use such a goggle, as the lenses given to those who have lost their lenses (aphakic) are over-magnified due to reasons such as surgery or injury in one eye. The magnification factor in contact lenses is very low and can be easily tolerated by the patient. Thus, the patient becomes able to use both eyes.
