Question
A nearsighted woman can’t see objects clearly beyond 40.0 cm (her far point). If she has no astigmatism and contact lenses are prescribed, what power and type of lens are required to correct her vision?
Step 1
This means that a virtual and upright image should form at the image distance, which is also equal to the negative value of the 40 cm. So, we have $q = -40$ cm. Show more…

A nearsighted person cannot see objects clearly beyond $25.0 \mathrm{cm}$ (her far point). If she has no astigmatism and contact lenses are prescribed for her, what (a) power and (b) type of lens are required to correct her vision?
A nearsighted woman has a far point of $300 \mathrm{cm}$. What kind of lens, converging or diverging, should be prescribed for her to see distant objects more clearly? What refractive power should the lens have?
