The lens maker equation:

$\overline{)\frac{\mathbf{1}}{{\mathbf{s}}_{\mathbf{o}}}{\mathbf{+}}\frac{\mathbf{1}}{{\mathbf{s}}_{\mathbf{i}}}{\mathbf{=}}\frac{\mathbf{1}}{\mathbf{f}}}$

**a.**

The power of the lens is given as, P = +2.0 D

Since the contact length has a positive power, it implies that the focal length of this lens is also positive.

Ramon has contact lenses with the prescription +2.0 D.

a. What eye condition does Ramon have?

b. What is the near point without the lenses?
