A person can read at the closest distance of 50cm. in order for him to read at 30cm. Identify the defect, nature and power of lens?

The defect is Myopia. Diverging lens(concave lens)should be used.

Explanation

Myopia or Nearsightedness occurs when the eye loses its ability to focus on far-off objects as the lenses do not possess a long focal length. Objects that are near are clearly visible to patients of this defect. A diverging lens can be used to fix the problem of nearsightedness
