  1. A cylinder-shaped lens.
  2. Bifocal or multifocal lenses.
  3. A convex lens.
  4. A concave lens.
Explanation

Answer: D - If a patient can see close objects clearly, but objects farther away are blurry, they will need a concave lens.

In a patient with myopia, or nearsightedness, close vision is clear while distance vision is blurry. This patient will need a concave lens, or a lens which curves inward.
