HOYA VISION CARE CANADA
The iD Protegrity is "one of the most technologically
advanced lenses in the world," according to Dale Mouscos,
sales strategy and marketing supervisor for HOYA Vision
Care Canada.
The progressive lens design is "fundamentally different"
and incorporates a unique design process and technology
that HOYA argues is "unmatched by any other
lens manufacturer."
iD Protegrity utilizes an Integrated Double Surface design
and has an integrated progression on the front and back
surfaces. The front surface is aspheric and contains the
vertical progression component. The back surface is atoric
and contains the horizontal progression component. When
the two sides are integrated in the final product, both compo-
nents represent a fully customized design built upon
prescription and frame parameters.
The components of progression of iD Protegrity are
distributed on both the front and back surfaces of the lens
and depend on each other to function and cannot do so
independently.
Normally all the progressive components for the refractive
eye correction are positioned either on the back surface or
on the front surface. This means choosing between a wide
visual field with a long corridor length or a short corridor
with a limited visual field.
HOYA's technology integrates the best of both worlds:
a short and effective vertical corridor length that makes
excellent use of the eye’s natural rotation. The horizontal
component is placed on the backside closer to the eye with
a shortened vertex distance facilitating a wider visual field
with minimal distortions.
TRANSITIONS
Transitions Signature VII lenses are fully clear indoors
with an optimal outdoor tint that is more responsive to
UV than ever before thanks to Chromea7 technology. These
lenses have the fastest fade back speed of any Transitions
everyday lenses and are available in grey, brown and
graphite green. They block at least 20 per cent of the
harmful blue light indoors and over 85 per cent outdoors.
Transitions XTRActive lenses are for patients who are
sensitive to light and/or are concerned about eye health,
eye strain and fatigue. They offer extra protection from
light with superior darkness outdoors, even in hot tem-
peratures, and a hint of tint helps protect from harsh indoor
lighting. They also activate behind the windshield of
a car and are available in grey, brown and graphite green
and also help to provide more protection against blue
light by blocking at least 34 per cent of the harmful blue
light indoors and 88 to 95 per cent of harmful blue
light outdoors.
Transitions Vantage lenses are for patients who spend
a lot of time outdoors and want vibrant outdoor vision.
These are the first and only lenses that are virtually clear
indoors and darken and polarize outdoors. Transitions
Vantage lenses have
variable polarization for crisper, sharper vision outdoors
even in the brightest glare. They also reduce exposure to
harmful blue light, blocking at least 34 per cent indoors
and over 85 per cent outdoors.
