Use the recut lens tripod (option) for a high base lens, a recut lens or a decentered lens (option).
Position the lens on the tripod.
Move the lens slowly until the micro-engravings are:
• symmetrical in relation to the graduations,
• aligned on the line corresponding to the PRP of the lens.
The PRP value of Essilor mid-distance lenses is 6 mm. This may vary depending on the
manufacturer of the lenses.
The lens is centered and ready to be blocked.
To carry out lens blocking, refer to the section Lens Centrering > Blocking a lens (F p.61).
