Contact Lens :
Contact Lenses are prosthetic devices which are usually thin curved lenses placed directly on the surface of the eye in order to correct vision. Contact lenses are primarily used as an alternative to eyeglasses. They are used to correct refractive errors such as myopia, hyperopia, astigmatism and presbyopia. These lenses exactly do the job of your bulky eye glasses, by allowing you avoid the need of the frames. Contact lenses come in various types including soft lenses made of flexible plastic material and rigid gas permeable lenses. Contacts require proper cleaning and disinfection to prevent eye infection and discomfort and are available for both extended wear and daily disposables. Regular eye examinations are necessary for eye health and to ensure the proper fit and prescription strength of contact lenses for optimal vision correction and comfort.
