I am a worker in a factory where i have to read small (sometimes handwritten) fonts from a long dist (5 -12 feets ) what to do i cant carry binaculors always which specs should i use ?One said -3.0 for on eye & - 5.0 for another would be nice. Please help me.
      Answer1:You certainly want some sort of a magnifier. I would go to a place like Walmart and look at the glasses there. The stores are large enough that you might approximate the distance that you will need at the font you are reading at work.Who know? Maybe it will work,
