Be careful if you consider progressive lenses. Once your brain gets used to them, they work fine in the office where the continuous focus is important. But, because of the way the progressive lenses are made, the lower outside portion of the lens is essentially uncorrected glass/plastic, which makes it nearly impossible for me to look back over my shoulders and focus on anything. Focusing on the roadway in front of you (near or far) is essentially all "long" distance, so I got bifocal lenses with a very small bifocal portion (so that I can read if I have to do so).
