Wire frames for flat lenses

[michael_scorsi]

Hello,

I am hoping for a recommendation regarding how to identify frames suitable for flat lenses. We would like to provide glasses with some specialty lenses that are Base 0. It seems that this frame style used to be common. I have a pair of old Titmus frames that are a good example of this (photo attached).




Do you know of any manufacturers that still provide wire frames for flat lenses? Do you know if any manufacturers include a specification in their catalogs regarding frame curvature?

Thank you,
Michael
