There is a solution. The lens type is called double D , there are segs above and below, with the middle between them for distance. This lens has been used for years by mechanics, electricians.
It may be hard to find on line, as they dont sell a lot ( lots of guys dont know or optician didnt advise), but maybe as a special order but definitely a B/M. Double D FT28 or 35 ( width of top, 28 much more common) On Oct 20, 2:48 am, Paul <[EMAIL PROTECTED]> wrote: > Try asking online vendors if they'll do this for you. > > If nobody will do this, you can try this trick if your prescription is > the same (or close to it) in each eye.
