Hi, I'm an inventor and am relatively familiar with the BU, BD, BO, BI system, but, I find that I need to learn the 360 degree system.
First: Is the following format correct?
Rx: OD 3.0 D Sph 11.5 Δ base 64.6°
OS 2.0 D Sph 7.7 Δ base 244.6°
Second: Is there an on line document that you could direct me to that clearly describes that system?
Thanks for any help.
Roger
