of the HEV light spectrum,” says Rick
Leroux, director, marketing and com-
munications (Lenses) at Centennial.
Centennial also offers finished poly-
carbonate lenses in Transitions
Signature and XTRActive, as well as
SunChangers photochromic lenses
with Ultra AR.
“Since children tend to spend their
time going between indoors and out-
doors, they may want the convenience
of photochromic lenses,” says Leroux.
“In addition to changing automatically
from clear to dark, these lenses also
provide UV and some HEV.”
There is a special children’s lens on
the market - The Shaw lens - which
was developed and created by Dr.
Peter Shaw, specifically designed for
children with special eye conditions
such as lazy eye.
The Shaw lens is a technology company
that supplies free-form, ophthalmic
lens designs for the treatment of
binocular vision disorders and elimi-
nates the unwanted, coincidental
binocular side effects of eyeglasses.
“It is well known that eyeglasses can
introduce magnification and prism
differences causing impairment as
to how the eyes team together,” says
Shaw. “The Shaw lens resolves these
differences through a patented,
28 OPTICAL PRISM | July 2018
novel, game theory, computer iterative
method involving over 30,000 calcu-
lations per design to optimize a lens
design that is both isophoric and
iseikonic.”
Shaw lens designs are available in most
lens classes including single-vision,
progressive addition and bifocals in
photochromic, polarizing and clear
options. Shaw Lens technology is par-
ticularly helpful for patients that have
or are indicated to be at risk to adapt
poorly to eyeglasses typically due to
the consequences of correcting
anisometropia.
Shaw Lens technology is ideally
suited for the correction for serious,
sight-threatening, childhood vision
disorders of amblyopia and strabismus.
Shaw Lens is 100 per cent Canadian
technology.
In Canada, the main supplier of the
patented technology is Plastic Plus.
Transitions lenses are also an ideal
choice for children, as one pair does
it all, seamlessly. “They block 100
per cent of UVA and UVB rays and
they help to filter harmful blue light
both indoors and especially outdoors,
where the sun is the largest source
of blue light,” says Patience Cook,
director, North America marketing
for Transitions.
