Hi,

My Optometrist can find blended bifocals for rimless frames in
polycarbonate but not in Trivex. I would much prefer Trivex because, as
I understand it, this plastic is strong, resistant to cracking, and
lower in aberrations.

Are there any manufacturers of blended bifocals in Trivex?

Thanks

they make progressives, but not blended. blended bifocals are pretty
poor optically anyway, with that large zone of blended blur between the
distance and near zones. consider getting a true progressive like the
trivex ECP or Summit CD

w.stacy, o.d.

Genesis, Concise, Unique, and Image are also available in Trivex.
