Contact Lenses are simple to wear and care for, and are almost undetectable. They are thin discs of plastic, curved on the inside to fit properly onto the surface of the eye, and shaped on the outside to correct and improve defective vision, for bandaging the eye after surgery, and cosmetic benefits e.g. to cover white scarring of the eye or to change the color of the eye for fashion.
Sanjivani Eye Hospital in Ahmedabad With advancing technology Contact Lenses can correct all forms of visual defects including Astigmatism safely and comfortably. There are basically two types of contact lenses : Rigid and Soft. Both types come in varying materials with different levels of oxygen permeabilities. The higher the oxygen permeability the better it is for the eye.
Contact Lens care is the most important part of contact lens wear. Good eye care also includes proper care of the lenses. All types of contact lenses should always be kept clean, disinfected and hydrated. Lens hygiene is the key to a comfortable wear. All contact lenses accumulate a variety of deposits, from the eye itself whilst wearing them, and from the environment. The tears of the eye contain proteins, lipids (oily secretions), mucous and calcium. The environment also contributes towards building up of these deposits especially on soft lenses. The chemical pollution from cars, factories etc., dust, metal in the air get embedded onto the surface, causing harmful contamination on the lens surface, over a period of time. In order to prevent these deposits, all contact lenses should be cleaned, soaked and disinfected daily.
