I could use a recommendation for the following prescription:
O.D. Spherical -13.75, Cylindrical +1.25, Axis 105
O.S. Spherical -15.25, Cylindrical +2.00, Axis 100
Patient currently has a 1.66 index lens that is 4-5 years old. Thickness and weight are both a consideration, though patient is not unhappy with current thickness and weight. Current frames are 41mm, keeping thickness on the edge fairly minimal. New frame is not yet picked out, but will steer toward another small one.
In reading past posts, I surmise that 1.74 could be noticeably thinner in this particular prescription, but would it also likely be heavier than the 1.70? Should I assume that while the 1.90 glass is even thinner, that (being glass) it would also be quite a bit heavier? Price is less important than finding the right material to use.
Thanks for any help :)
