I wear progressive lenses, but have discovered that my vision is just right
now to allow me to focus at a 10" distance without even wearing my glasses,
so when doing really close work, I just switch out to regular safety glasses
and stay clear of moving parts.G

I used a Brown and Sharp vernier caliper until I got tired of adding
17 to 75. Then I bought a Mitutoya dial caliper. Then I discovered
Harbor Freight's $19.95 digital calipers. Zero it anywhere, measure
in metric and english, same feel as a good pair of Mitutoya
calipers...Harbor Freight digital measures in my shop now.

Vernier Calipers are the simplest and probably the most rugged, the
smaller
ones have a 25 division vernier scale and may be hard to read. Larger
ones
have 50 division scales and are fairly easy to read until your eyes go
bad.
I bought my digital caliper when I could no longer read the vernier
without
a magnifying glass. Now I can't even read the digital calipers (that have
½
high digits) without my glasses. I now really appreciate how hard it is
for
kids with bad eyesight to learn. I make a lot of mistakes because I can't
see details like I used to. When I am working it is often rather hard to
get my head positioned in just the right spot to bring things into focus.
