Calculate maximum power of accommodation (in diopter) of a person having normal vision. |
|
Answer» We know that, the distance a normal eye can see is up to 25 cm. So f = 25cm Now P = 1/f, In this formula f is in m. So, we divide f by 100 i.e. 25/100 = 1/4 m Hence, P = 1/1/4 = 1 × 4 = 4D Therefore, the power of accommodation of a person having normal vision is 4D. |
