Contact lenses are thin, curved plastic disks designed to cover the cornea; the clear front covering of the eye. Contact lenses provide a safe and effective way to correct vision when used with care and proper supervision. They can offer a good alternative to eyeglasses depending on your eyes and lifestyle.
History of the Contact lens
Leonardo da Vinci had proposed the idea of applying a corrective lens directly to the surface of the eye as early as 1508 and similar concepts surfaced from René Descartes in 1636 but it was not until 1887 that the German physiologist Adolf Eugen Fick constructed the first successful contact lens.
