HOW DOES THE ADVANCEMENT
OF LENS TECHNOLOGY BENEFIT
THE WORLD OF EYEWEAR?
“Technology drives many sectors of the economy. Advancement in
processes and products can help to motivate buyers to explore new
concepts and features. Eyewear has benefited greatly from today's
emerging technology in its ability to customize lenses to the specific
needs of the vision care consumer. Consumers need tailored
solutions to the extra demands placed upon our visual system.
Technology is a pillar in an opticians’ building of those solutions.”
Robert Dalton,
Licensed Optician, Executive Director,
Opticians Association of Canada.
“New lens technologies stand to benefit eyeglass
wearers. Most promising are the new ‘digital’ high-
definition lenses. The fabrication of these lenses is
optimized with computer-controlled surfacing
equipment which is much more accurate than con-
ventional surfacing methods. Another technology
just being advanced is for so-called ‘wave-front’
high-definition lenses. This technology is similar
to wave-front-guided LASIK surgery.”

Society, Professor of Ophthalmology and
Vision Sciences, Faculty of Medicine,

“The area of contact lenses
in both soft and custom gas
permeable lenses is developing
rapidly, providing optometrists
with more services to offer
patients. For instance, materials
are improving comfort, increas-
ing parameters are improving
accuracy, sclerals are helping
with corneal ectasias and
dryness, and more lenses are
available to control myopia
and reshape the cornea.”
Dr. Shalu Pal,
Member, Ontario Association
of Optometrists.
“Frame designs were previously limited by Rx
ranges, depending on their curvature and size.
That range has been broadened substantially
with advancements in lens materials and
freeform lens design. By choosing the proper
material, considering the frame curvature and
the positioning of the frame on the patients
face, you can provide more frame options for
the patient and still provide great fields
of vision.”
