In brief: Accommodation

Both the cornea and the crystalline lens function to refract the light into eye.
The lens also has the additional function of changing shape through accommodation to give you stronger near focus. This process is what allows younger people to read without glasses and why people over 40 need reading glasses as the lens loses it accommodation.
