Dears Student,
if a near point of an eye is 20 cm and far point is infinity as the ideal
if a near point of an eye is 20 cm and far point is infinity as the ideal
position of perfect eyesight for the near point and far point is 20 cm and infinity.
Hence he does not need spectacles.
Hence he does not need spectacles.
