A contact lens is a thin, curved lens placed on the film of tears that covers the surface of your eye. The lens itself is naturally clear but is often given the slightest tinge of color to make them easier for wearers to handle. Today’s contact lenses are either hard or soft. Most people wear the latter form now, but it wasn’t too long ago that contact lenses were even glass blown!
Types of contact lenses
While contact lenses are still most commonly worn for vision correction, there are also contact lenses for purely cosmetic and novelty purposes. Colored contact lenses can enhance or completely change the hue of your eyes, and costume contact lenses can help create some of the special effects you see on the big screen.
