Which would be the best option to recommend to the patient with this prescription?

Prescription: OD -.25 and OS -5.75 with a PD of 66
  1. To recommend the smallest frame the patient can handle with polycarb lenses
  2. To recommend a small frame and suggest regular CR-39 or polycarb for the OD and a 1.67 high index lens for the OS
  3. To let the patient pick any frame and order 1.67 high index lenses for both eyes
Explanation
Answer: B - The best option for the patient would be to recommend that the patient have a CR-39 or polycarb lens for the OD and a 1.67 high index lens for the OS.

To have the patient see the best, the frame should be as small as possible but still comfortable. Ordering the left eye in a high index material will give the patient more symmetry and be thinner, giving the appearance that the lenses are more equal in thickness.
