That becomes a +15 sphere, and about the only thing is Aspheric Lenticular from Signet Armorlite, maybe the Bristolite semi-aspheric or something from Aire-O-Lite. My earlier work history includes helping low-vision patients, and I am sorry to see that the patients who "need" lighter lenses (poly, 1.66) are being neglected by the manufacturers who put their money into fancy PAL's. It is one area of optical/medical care where available treatments have decreased!

We can do high power +Rx in hi-index aspherics, lenticulars, or combination of thereof in any plus power, SV os Bi-focals.
