A man can see only between 75 cm and 200 cm. The power of lens to correct
the near point will be
- 3 D
- 8/3 D
The near point of a hypermetropic eye is 1 m, what is the power of the lens required to correct this defect? (Assuming that the near point of a normal eye is 25 cm)
If the near point of a far-sighted eye is 1 m, what is the power of the lens required to correct this defect? (Assuming that the near point of a normal eye is 25 cm)
