Stability Ball as desk chair

Keep in mind that switching between High Beams (bifocals) and Low Beams (mid-distance computer glasses) gets old fast.

Progressive lenses are more expensive but are well worth the investment. Since you already have frames you can use, you won't be shelling out a big chunk of change.

I have progressive lenses, but the mid-distance portion of the lenses are in the wrong place for my monitors I will be discussing this when them when I get my new glasses. If I were taller it would likely be less of a problem, I have a short torso. I've never had traditional bi-focals.
