Which eye condition is most closely associated with the hardening of the crystalline lens?

  1. Myopia

  2. Hyperopia

  3. Presbyopia

  4. Astigmatism

The correct answer is: Presbyopia

Presbyopia is the age-related hardening of the crystalline lens, resulting in difficulty seeing close objects. Other options such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (a distortion in the shape of the lens) are caused by different factors and do not involve hardening of the lens. While these conditions may also result in difficulty seeing objects, they are not specifically associated with the hardening of the crystalline lens.
