Lens fit check
A visual warning enables you to check the lens fit: any part of the lens outside the shape is displayed in red.
You can modify the PD and pupillary height to get the shape to fit into the lens, but if the induced prism is too great, we
advice you to order a new lens in the proper diameter.
To carry out lens blocking, refer to the section .Centering a lens > Blocking a lens (p.80)
