A myopic adult has a far point at `0.1 m`. His power of accomodation is `4` diopters.
(i) What power lenses are required to see distant objects ?
(ii) What is his near point without glasses ?
(iii) What is his near point with glasses ? (Take the image distance from the lens of the eye to the retina to be 2 cm).

Explanation

To solve the problem step by step, we will address each part of the question systematically.

### Given Data:
- Far point of the myopic adult, \( d_f = 0.1 \, \text{m} \)
- Power of accommodation, \( P_a = 4 \, \text{D} \)
- Image distance from the lens to the retina, \( v = 2 \, \text{cm} = 0.02 \, \text{m} \)

### (i) What power lenses are required to see distant objects?
