Hello everyone, I need little help.

I have one sport sunglasses (axa angle of frame iz 28°), and the base of lens is 7. Dioptry is OD - 1.25 OS - 1.00

I used a Nidek Le 9000sx and blocker CE-9. It's first time to I do that kind of glasses. Can I trace only the demo lens, or I must to trace frame?


Can somebody teach me how to do that?
