A contact lens is a thin, curved, and clear plastic lens placed on the surface of the eye for better and improved vision. These lenses float on the tear film that covers your cornea. A contact lens is a medical device prescribed to correct vision or for cosmetic reasons. Contact lenses are more comfortable while driving, playing sports, and other outdoor activities as compared to spectacles.
