One option is to get glasses with the largest bifocal (bottom lense)they will make you. Even if you don't like bifocals. You only use the very top of your glasses for shooting. Or look under the glasses if you don't need close up lenses.
Like Kenny said, you think you can keep track of your turns but you will get so lost with switching winds you'll wonder how you even got to the range.
MVA are top of the line, but I switched to Hoke cause I can read them better. Just personal preference.
