A particular person's eye is $2\mathrm{.}25$ cm in diameter. It has a near point $($the closest an object can be and still be seen in focus$)$ of $25$ cm $,$ and a far point $($the farthest an object can be and still be in focus$)$ of infinity.

What are the effective focal lengths $f_{\text{n}\text{e}\text{a}\text{r}}$ and $f_{\text{f}\text{a}\text{r}}$ of the focusing mechanism $($lens plus cornea$)$ corresponding to the near and far points, respectively, of this particular eye?
