Hi,
I would like to be able to calculate the GBASEX as well as GCROSX in TIND for any kind of FRNT base.
I used the calculation for thick lenses in order to compensate thickness but the radius I find in my calculations is not ok. I still have slight difference with the rx I required.
I first start only with a minus sphere in order to do not have to recalculate the thickness each time.
Do you have any idea ? is there some compensation to apply
Thanks
Aurélien
