[CQ-Contest] Size of Dual Monitors

I have worked in computers all my life.  I own two pairs of bifocals.  
One is progressive for driving.  They let me drive, read maps and focus 
on the speedometer all with one pair of glasses.

The other pair is computer-distance on the top and reading on the 
bottom.  This lets me work on the computer and see the keyboard or read 
something with the bottom portion.  I did not like the progressives for 
this purpose. The area in which the focus is sharp is small at computer 
distances with progressives.  I have to move my head too much with them.

The key thing with computer glasses is to *measure* how far your eyes 
are from the screen.  I made a bad estimate of that at the 
ophthalmologist once and had to get another exam and new glasses. Tell 
whomever does your refraction that distance and do the reading test at 
that distance.  It matters.
