A person A can clearly see objects between 25 cm and 200 cm. Which of the following may represent the range of clear vision for a person B having muscles stronger than A, but all other parameters of eye identical to that to A?
Ciliary muscles of person B is stronger than A. When person A can view in range of 25 cm to 200cm,the same distant vision of 200cm is for person B because while viewing far images, the muscles are relaxed.
Now the muscles can contract more than 25cm for person B, hence he can view clearly even at 18cm.
