A contact lens is a corrective, cosmetic, or therapeutic lens usually placed on the corner of the eye. Leonardo da Vinci is credited with describing and sketching the first ideas for contact lenses in 1508, but it was more than 300 years later before contact lenses were actually fabricated and worn on the eye.
