Shamir Duo™ is an invisible digital bifocal lens solution for the loyal flat top bifocal wearer. It allows the optician to deliver to patients, a multifocal, invisible to everyone but the wearer. Unlike older seamless bifocals, unique to this lens is a no jump segment. The segment is continuous with the lens' distance portion. This helps with easy adaptation and patients will appreciate the size and invisibility of the segment.
