Hi I've been wearing glasses on and off for the best part of 30 years - more off lately. Recently I got my eyes checked and had the following prescription prescribed R: F +0.75 -.0.50 175* L: F +2.50 -1 10* (My left eye is not very good) when I wear my specs now everything looks like it is in Bold, and not as sharp as not wearing my glasses. If I cover my left eye everything looks great, but if I cover my right eye things are better but not sharp. How long should it take for my left eye to tune into the new glasses? previously I put new glasses on and everything was fine. any ideas? thanks David
