One lens per eye.
However, most of the focusing power is not in the lens, but in the curved outer surface of the cornea, the transparent outer layer of the eyeball. The lens is present to give your eyes variable focusing ability. The shape of the lens is variable to allow you to focus over a wide variety of distances, from close in (reading this) to infinity.

Case I: One human will have two eyes.
1. If both eyes are fuctioning normal then there will be two lenses.
2. If one is functioning even then there will be two lenses.
3. If both eyes are not functioning with Spectacle then there will be 4 lenses two natural and two artificial.
Case II: One Human has only one eye
1. If eye is fuctioning normal then there will be only one lens.
2. If it is functioning with Spectacle then there will be two lenses.

Just one. It's an oval shaped, clear jelly thing (I dissected a cow's eye in Science class)
