the lens is a cover to protect our eyes like a book its got a cover to keep it protected the reason why we have it its because we would get diseases from dirt and all thing that blow around in the air.

The main function of lens is to do refraction of light so that it can reach retina(Rod and Cone cells basically) inside our eye.
