Do you have a special method?

As you hear from Essilor(Vision Printing System), Ipseo designed bese on individual habit. One is eye mover and the opther is head mover.

I regard the concept is as a most advanced design concept in PALs. In addition, I know head mover is better adapt to PALs than eye mover. However, unfortunately, there is no method to determine whether he/she is eye mover or head mover without use special equipment such as VPS.

If you have any method or skill regarding above matter, Please let me know.

IMHO - It has seemed to me over the years dispensing that hyperopes are more often "eye-movers" and myopes tend to be "head-movers".

Well remember, the Ipseo does not just base itself on one or the other. It uses a coefficient range and a stability calculation. So it is not just two designs, it is truly an individually designed lens.

I will quite often reach an arm up and wiggle my fingers about 20-30 degrees off where the patient is looking. The patient will always look over at my fingers (perhaps they don't trust me? ;) ), and I can get a feel for whether they are head, eye or combination movers. I know this isn't scientific and I'd never pick out a lens based on that but it gives you an idea if they will adapt quickly to a PAL or not.
