While there were several intermediate steps (H. Newbold appears to have designed a similar lens to Aves around 1913), there is evidence to suggest that Duke Elder in 1922 developed the world's first commercially available progressive lens (Ultrifo) sold by "Gowlland of
Montreal". This was based on an

From sales of 6,000 lenses in 1959 to 2,000,000 in 1969, Varilux was becoming a successful venture, but the market still had some concerns regarding the adaptation time to the lens. Still working at improving his original invention using new technologies and calculations, Maitenaz and his team were

The
Varilux X Series optimizes visual performance for tasks within arm's reach. Its technology ensures simultaneous vision of multiple near distances to achieve high visual clarity for activities at all distances and reduce the number of head movements necessary to find the optimal point of focus.

In 1993, Varilux
Comfort was launched and became the world's best-selling progressive lens. Varilux Comfort represented a new concept of the progressive lens, it was the first progressive lens which combined the advantages of a "hard" design (type Varilux) and a "soft" design (type Varilux 2). The

As new technologies and manufacturing processes were being developed, the research efforts concerning
Varilux continued. In 1988, the result came with Varilux Multi-Design, or VMD. The Multi-Design concept was a first stage of personalization of the progressive lens, a specific optimum design for

The
Varilux Physio progressive lens is characterized by an improvement in colour contrast and wider fields of vision. It derives its performance from a patented innovation called the Twin RX Technology which combines a method for calculating lens optics, Essilor's Wavefront Magement System and

The
Varilux Ipseo New Edition is the first lens designed and tested using a virtual simulator. The lens is personalized to the wearer's visual behaviour, using 10 customization criteria. To do so, it uses the Vision Print System, which measures a personal diagnosis of eye and head movement.
168:
The first patent for a progressive lens was
British Patent 15,735, granted to Owen Aves with a 1907 priority date. Aves' patent included the progressive lens design and the manufacturing process. However this was unlike modern progressive lenses. It consisted of a conical back surface and a

s bifocal lens, the
Diachrolux, and its trifocal lens, the Trilux. Without much brainstorming, Maintenaz's progressive lens was given a name following suit with the other premium products: Varilux. The lens was launched officially in May 1959 at the

With the launch of
Varilux Comfort in 1993, Essilor developed the dioptric loop method, making it possible to gauge wearer satisfaction. It involves using repetition until an effective result is achieved for the wearer. It comprises five stages:

After patents and calculations, this type of progressive lens appeared to be possible, but had yet to be manufactured. Maitenaz and his team began producing progressive lenses using a variety of different improvised techniques and by 1958,
