What are the advantages of Seiko’s
back-surface design?
To begin with, the front surface shape
magnification differences between visual areas are
eliminated. In conventional progressive lenses, distortion
is induced by the shape changes on the pre-molded front
curve, and by power changes on the back. The front surface
on Seiko free-form lenses is a perfect sphere, eliminating
distortion due to front surface shape changes. The wearer
experiences a considerable reduction in overall size and
skew distortion, with a virtual elimination of image sway
& swim.
Technically, the lens provides for total
control of marginal astigmatism and power error through
aspheric compensation for each Rx. This mean for each
sphere, cylinder, axis prism and add power, the patient
provides a truly customized lens with an exact Rx for near,
an exact Rx for intermediate, and an exact Rx for distance.
What type of patient benefits from
this new innovative product?
Seiko’s 100% back surface design
provides ECPs with a product that can be custom made to
their patients’ exact visual needs. These lenses are
lifestyle-dispensing friendly, with multiple lens designs,
multiple fitting heights and a variety of material and
coating options.
Seiko and Perfas free-form lenses are
designed for people who appreciate wide distance vision and
who require the widest reading and intermediate areas. They
are the perfect first pair of progressive lenses and ideal
for replacement or for patients sensitive to the distortion
in regular progressive lenses.
Are they easy to fit for a patient?
Seiko and Perfas free-form lenses are as
easy to fit as a conventional progressive lens using a
monocular PD while ensuring proper lens height.
What is the wearer’s success rate?
After a decade of continual design
advances and global distribution, the wearer success rate is
over 99%.
What indexes are the Free-Form lenses
available in?
Seiko and Perfas free-form lenses are
available in an incredible choice of material and coating
options. Indexes include 1.67, 1.60, 1.59 (poly), 1.53 and
1.50. Certain indexes are available in polarized and
Transitions® lenses, featuring the latest Transitions VI
photochromic. They are also compatible with high-quality
aftermarket anti-reflective (AR) coatings.
What does the future hold for Seiko
