In case of Myopia, the image is formed in front of the retina. And in case of Hypermetropia, its formed behind the retina. Where is the image formed in case of Presbyopia? :S

Expert Answer:

in  hypermetropia the cause of this defect is shortening of eye lens,focussing problem of the lens.
same problem is caused in presbyopia but due to some other cause,...due to weakening of eye muscles and hardening of lens it can not focus the light rays on the retina.
