Answer 1

Correct ans is-

your lens can’t get flat enough; you need a diverging lens in front of your eye.

Because, when we see a far away object our eye lens gets flatten. But after a distance eye can not see clearly because our eye lens is enable to flatten enough to form image on the retina (beyound accomodation power). In this case the formed image will be in front of the retina so we need to use a diverging lens so that eye can form the image on the retina.
