can it read a dial caliperGuide dog?![]()

I was shocked to see most apprentices can't read a dial vernier!
Oxford do a good headband thing with lenses on the front.
dial caliper vernier is a scale 
Mine was till I was diagnosed diabetic with high blood peressure and put on meds ..it took jut over 12 weks for it to settle to a use full vision that was almost the same as i was four years ago . So there is hope for you yet .
