Critical Reasoning

As people age, their near-focus eyesight tends to worsen because the lens inside the eye loses flexibility. Some people perform what are known as optometric exercises, which are meant to strengthen the eye and prevent a loss of near-focus eyesight. So far, independent tests have not shown that these exercises have had an effect on preventing or slowing the loss of flexibility of the lens of the eye.

If the statements above are all true, they most strongly support which of the following conclusions?

A. Optometric exercises have not been shown to prevent or slow the loss of near-focus eyesight.
B. There is no method of reducing the flexibility of the lens in the eye as one ages.
C. Measuring the flexibility of the lens in the eye is only one of several ways to gauge near-focus eyesight.
D. The rate at which the lens of the eye loses flexibility increases as one ages.
E. Exercises that are meant to improve eyesight are not effective as one ages.
