-transparent to allow light into the eye

-curved to refract light to the eye

(ii) Rods for vision in dim light/low light intensity; cones for vision in high light intensity

(iii) Ciliary muscles relax; suspensory ligaments become tight and pull the lens; the lens become thinner and less refractive; light from a distant object is less refracted so the image is formed in the retina.
