Stability Ball as desk chair

[Catrin]

Catrin, I wear progressives and I find I get better results buying the progressive glasses locally, maybe because I have astigmatism and a strong prescription both. My spouse with a simpler progressive prescription uses Zenni. I do like using single vision glasses for reading and long computer work so I buy the cheap Zenni ones for that and they work just fine. Plus, it is fun to get some of the wilder frames.

I do have a.complex prescription and spend many hours building traffic simulation models, I thinks getting a pair of single vision glasses for work is a very good idea.
