I have read a lot since my last post and also gave up the idea of
ordering online.

I found a frame at a store which I also found it at framesdierct.com.
Under Eyeglases, it is FLEXON 613. See at

http://www.framesdirect.com/framesfp/Flexon-lcrdkf/r.html
Measurement is 48-18-30.4-135.

My prescription (for progressive - I'll be doing noline bifocal) is

   Sph;  Cyl;  Axis
R:+1.00; -0.75; 150
L:-0.25; -0.50; 040  (add+1.50)

PD- MonoR: 28
PD- MonoL: 30

I need the best possible vision for Near, Intermeidte, and Distance.
Noting that I need to be doing programming work on computer while
reading from books at the same time, (1)what types of lens (Panamic, or
Ellipse) and (2) what materials (CR39 or mid-index or high-index)I
should use to get the best vision with my choice of frame?

BTW, what exactly is fiting height?

Again my info is:
