First contact lens was processed and introduced to the world as far back as 1887 which had two glass layers within which a substance, called ‘gilletine’ was inducted. But, at that time, there was no method to measure curve of the eye. But due to their heavy weight, such lenses could not gain prominence due to obvious factors. It was in 1943 that first plastic lens was processes and introduced to the medical world. The plastic contact lenses could be easily fitted on the front portion of the eyes and were called sclera contact lenses but could not gain popularity. Thereafter, corneal contact lenses were processes and introduced in the market in 1948. These lenses can be easily fitted over the transparent part of cornea and are quite easy to fit and remove, whenever necessary.
