cornea, aqueous humor, lens and vitreous humor
A lens is.
Water, gasses. Any other medium that has a different "n" value gives rise to a bending of light.
bend it They bend the light so that the cornea and (eye) lens may focus the light on the retina.
Light rays.
the pupil; light enters the eye through it its black because most of the light colours are absorbed. it is covered by the lens and cornea and surrounded by the iris (the colour of the eye).

The lens focuses light by bending the light to make it strike the retina in the right angle

Refraction is the direction of light propagation that can be changed at the boundary of two media having different densities. Defraction refers to the "bending" of light.
When bending light rays to focus them on the retina the two structure involved are the air-cornea interface which accounts for about two-thirds of the light-bending process and the lens which accounts for the remaining third but also makes the necessary adjustments to allow the eye to focus on objects at different distances.
