I was an Optometric Assistant for quite a few years, so maybe I can help you a little!
Do you drive and read street signs okay? I would think by the way you describe your vision, you would be within the parameters mentioned. 20/60 vision is not horrible, but I would think you would be having more issues than you mention.
I think the only way to know for sure is to get your eyes checked. By what you say, I would guess that you could be at 20/30 or 20/40, but some people go through life not even realizing that they could be seeing things alot better! I had people come into my office that I was amazed that they even functioned, their vision was so bad, but they insisted that they could see just fine

My vision, uncorrected is 20/600
!! No, I didn't put too many zeros in there!! They don't use the eye chart for me, because I can't even see the big E
! The first time I got contacts I was amazed at how crisp everything looked - it was like being in a different world

Good Luck
