Darcy suffers from farsightedness equally severely in both eyes. The focal length of either of Darcy's eyes is 19.3 mm in its most accommodated state (i.e, when the eye is focusing on the closest object that it can clearly see) What lens strength (a.k.a., lens power) of contact lenses should be prescribed to correct the farsightedness in Darcy's eyes? (Assume the lens-to retina distance of Darcy's eyes is 2.00 cm, and the contact lenses are placed a negligibly small distance from the front of Darcy's eyes) Select the correct answer 2.19 D 3.49 D 1.37 D 2.45 D 2.98 D
