<prompt> For near point of 20 cm, a hypermetropic of 4D has to exercise accommodation of -4.0 D9.0 D10.0 D0 D  <response>: Ans- B 9.0 D AP-R where P-is the refractive power of the eye when fully accommodated and R-is the accommodative power of the eye at rest. Hypermetropes have their far point behind eye. Hence, R -4 Applying this to the formula A 10020 - -4 5 4 9 D.
