Draw ray diagrams each showing $(i)$ myopic eye and $(ii)$ hypermetropic eye.

(N/A) $(i)$ Myopic eye (Near-sightedness): In a myopic eye,the image of a distant object is formed in front of the retina instead of on the retina. This occurs because the eye lens becomes too curved or the eyeball becomes too long.
$(ii)$ Hypermetropic eye (Far-sightedness): In a hypermetropic eye,the image of a nearby object is formed behind the retina. This occurs because the eye lens becomes too flat or the eyeball becomes too short.
