Difference in acuity between eyes

Hi,
   Is it normal for one eye to have slightly better acuity than the other eye (after correction for refractive errors)? Or should vision pretty much be perfectly equal between your eyes. I have slight myopia, corrected with glasses, and I feel that it's easy to read the 20/20 with my right eye, but I struggle to read that with my left eye. I've been to eye MD's who say I have healthy eyes and 20/20 vision (although I can tell a small difference in acuity).
Thanks so much for your time!

Most people have a dominant eye that sees better than the other with and/or without glasses. Just like people usually hear better out of one ear or have one arm stronger than the other.
