Sixty-five-year-olds should drive cars with windshields because with age the eye's lens becomes transparent.

The answer is untinted; more cloudy.  The normal 50-year-old driver needs twice as much light to see too after dark as a 30-year-old. In dim or dark light, eyes adjust by broadening the pupils to let in light as could reasonably be expected. The iris contains small muscles that control the span of the pupil. As you get older, these muscles debilitate and don't react too to the need to let in more light. The outcome is a small pupil when you try to find in poor light.

This question is an opinionated one, and we don’t know anything about the module or anything, thus we can not answer it. but if you are having trouble on what it is asking basically it is just asking to (using your knowledge on the topic) say which topics you were most interested and which were the most challenging.hope this : p
