[Tig] eyesight- lenses

[pmendelson]

Rob,

In the second iteration I guided the technician in where the center point
should be.  Normally, they will have you put on the frames with dummy glass
and look straight ahead.  They will put a little dot at a point that
intersects.  This will be where (and I don't know the math here) some
predefined point on the gradient will fall.  I had been craning slightly
upwards in front of the computer.  By telling them to adjust that point
slightly upwards, I got a better compromise between far and mid vision.
In your case, you may have the additional problem of striking a compromise
that still yields a natural stance in front of a Telecine monitor.
Your mileage may vary.
