Your friend is having eye sight problem. She is not able lo see clearly a distant uniform window mesh and it appears to her as non-uniform and distorted. The doctor diagnosed the problem as
  • A
    Astigmatism
  • ✓
    Myopia with Astigmatism
  • C
    Presbyopia with Astigmatism
  • D
    Myopia and hypermetropia
✓

Answer

Correct option: B.
Myopia with Astigmatism
b
If distant objects are blurry then problem is Myopia.

If objects are distorted then problem is Astigmatism
