Well....... It has been very difficult. There was a problem with the frames being warped a bit. It is a pair made out of that metal that has memory. Apparently after trying to fix them the metal went back to the warped shape. In any case they were causing me to get very nauseous. As far as the trifocals go I was sort of getting used to some of it but I couldn't handle so much of the world being blurry. Driving in a rainstorm was terrible. Today I am heading back to the optician to get new frames and request bifocals. Thanks for asking. I think I will do okay with bifocals.
