Blended bi-focal reading gles?

I am 46 and require gles when reading or using the computer. I went to an eye doctor (sorta) and found that one eye is also weaker than the other. Regular reading gles were straining my eyes. I decided to go ahead and buy gles that I could wear all the time, bi-focals with the lines blended so it wouldn't look so stupid. The gles came in and while I understand there is some adjustment time involved in getting used to them I feel that the reading part is too low and too narrow. I made a deal with the eye gl people for them to redo the lens as per my percieved need but now I am worried that if the new lens come in and I still cant adjust I'll be out the 1000 (RMB) I spent. My question is should I risk losing the functionality of these glasses with new blended lens that may not work or should I forget about wearing them full time and just get reading glasses?
