Pearl
A New Generation of Trifocal Lenses
The TriNova Pearl features a bifocal geometry with a rear-surface bevel combined with an additional boost zone (effectively recreating a hybrid trifocal lens). The wearer enjoys sharp vision at each defined distance.
Pearl S
A bifocal lens with maximum power
The TriNova Pearl S allows you to create bifocal lenses that exceed standard specifications. When the two zones are combined, the total power can be very high (up to +12D).
