54. For a normal eye far point Is at infinity and near point of distinct vision is about 25cm in front of the eye. The cornea of the eye provides a converging power of 40D and least converging power of the eyelens behind the cornea is about 20D. From this rough data estimate the range of accommodation of a normal eye.
