hi all.
I'm PAL lens wholesaler and I have some questions about the prism on near reference point.
One optician often reject pal lens due to above problem. so, I ask of him.
Why are you rejecting lenses?
He talk to me that when he receive pal lens, he check lens.
distance power, add power and zero point of prism from DRP to NRP.
If the zero point of prism line towards temporal direction, He regards the pal lens is inferior goods.
Unfortunately, I can't accept his claim.
If you have any idea about this matter, pls explain me.
Regards,
