The lenses were developed using new, breakthrough
technology that combines a disruptive nano-
composite matrix and a new generation of ultra-agile
photochromic dyes.
The nano-composite matrix in Transitions Signature
GEN 8 lenses is a nano-structured material that mimics
a semi-crystalline structure. This matrix creates free
zones for improved dye mobility. Not only can the
dyes move more freely, but it is also more stable and
consistent in its performance.
“As leader and champion of the photochromic category,
our mission is to provide better vision and protection to
everyone. We are proud to introduce a new technology,
bringing a new level of performance, based on
consumer’s needs,” says Chrystel Barranger, president
of Essilor Photochromics and Transitions Optical.
The latest lens from HOYA Vision Care Canada is their
latest progressive lens, Array 2.
The second-generation Array builds on its flexible
backside platform and now incorporates Hoya’s
revolutionary Binocular Harmonization Technology
(BHT).
One of two key components around the Array
2 design is that it offers the broadest range of
availability in lens materials and coatings making
it suitable for everyday use as well as second pair
design.
The second significant design advantage is
the addition of HOYA’s patented Binocular
Harmonization Technology (BHT).
With BHT, the right and left prescription are treated
as individual components defining the required
binocular lens design and then the necessary
corridor length and progressive power distribution
are calculated. Patented algorithms and free form
processing technology are implemented to achieve the
finished product.

“We know that more than seven in 10 people have
a difference in prescription from their left to right
eye, which has an impact on adaptation and overall
comfort – BHT solves these problems and provides
a solution that ensures both eyes receive equal,
accommodative support, according to the needs of
each eye,” says Ahmos Henry, president of HOYA
Canada.
HOYA also recently launched LifeStyle 3, a new lens
design that is offered in three variations, Indoor, Urban
and Outdoor.
Indoor places emphasis on near vision focus, Urban
wearers enjoy equal focus on all main vision areas and
Outdoor puts primary focus on distance.
The Lifestyle 3 lenses also use HOYA’s Binocular
Harmonization Technology (BHT).
Nikon Optical Canada is launching SeeMax Infinite, a
replacement of SeeMax AP, the most advanced single
vision lens available on the market.
The technology behind this revolutionary lens takes
into account the comfort level, which is unique to each
person.
Nikon has developed a tablette application to measure
the sensitivity of a person to different aberrations.
Understanding what makes them more comfortable,
this measurement is the first subjective data Nikon is
able to collect from the patient besides the prescription.
As the demand on our eyes is constantly growing,
wearing lenses with high hand and ultra performant
technologies represents the simplest way to add quality
and comfort to our vision.
New technologies will also help alleviate visual stress
and provide higher accuracy in delivering outstanding
vision to the patient, says HOYA. OP
