Which statement is correct?

Question

Quizplus · Accepted Answer

The correct statement is: For close vision, the ciliary muscle is contracted and the lens is rounded. This is because when we look at objects up close, the lens needs to refract (bend) the light more in order to focus it on the retina. This is achieved by making the lens more rounded, which is done by contracting the ciliary muscle. For distant vision, the ciliary muscle is relaxed and the lens is flattened. This allows the lens to refract the light less, which is necessary for distant objects. The focal distance also increases as the light source moves further away, so statement D is incorrect.
