Seiko finished and semi-finished 1.67 Super SV
lenses are the most technologically advanced single vision lenses
available. They are based on Seiko's dual-patented MX aspheric
low-base design, and manufactured using high index MR-10 resin.
MR-10 is less sensitive to heat and does not readily contract or
expand--factors that can lead to warping and coating deterioration.
The manufacturing process uses individually surfaced production
molds utilizing Seiko's digitally precise Free-From optical
technology.
The patented MX design incorporates a 10mm spherical fitting button
in the center of the lens. This button eliminates aspheric fitting
problems, making patient accommodation practically automatic. The
design perfects optics throughout the entire lens, and corrects the
three primary aberrations in lenses--power error, marginal
astigmatism, and distortion--while reducing chromatic aberration.
Seiko finished 1.67 Super SV lenses feature true 1.0mm dimple-free
center thickness (-2.00 and above). They are hard coated with an
exclusive double hardcoat (DHC) protection system that provides the
safest 1.67 lenses available, even with 1.0mm centers. Seiko's DHC
not only offers excellent durability and scratch protection, it also
tints fast and consistently, and can be custom coated with any
quality AR coating.
Seiko finished 1.67 Super SV AR lenses are factory coated with a
16-layer high-impact AR process and new SuperClean hydrophobic/oleophobic
topcoat. This coating system is index-matched to the lens to
eliminate rainbow reflections (fringe interference) often seen with
other AR coatings To help prevent slipping during the edging
process, place a sticker designed for hydrophobic coatings between
the pad and lens.

Seiko semi-finished lenses are made from 16 extra-thick blanks to
provide the largest product range available. Semi-finished lenses
are available clear hardcoated and in Transitionsﾮ VI Gray and
Brown. This advanced photochromic technology gets darker in hotter
temperatures, gets darker faster, and fades back to clear faster
than ever before. Seiko 1.67 Super SV?with Transitions lenses
include durable hardcoat protection, as well as 100% UV-A and UV-B
protection. |

Transitions lenses set new standards of lens performance and provide
unparalleled benefits to all wearers. |

Largest Product Range
Finished 1.67 Super SV lenses are available from -10.00 to +6.00
(out to a -2.00 cylinder), and plano to -7.50, out to a -3.00
cylinder, with additional spheres at -10.50, -11.00, -11.50, & -12
.00. Semi-finished lenses can be processed to their full nominal
diameters from +10.00 to -15.00, out to a -6.00 cylinder, with a
total power of -15.00 diopters. Certain higher minus Rx's or
cylinders beyond -6.00 may be processed. Consult your lab.
Easy to Fit
Unlike conventional aspheric lenses, the patented MX design and
spherical fitting button make Seiko 1.67 Super SV lenses forgiving
of marginal fitting errors. For best results, measure monocular PD
and pupil heights, and ensure the optical centers are fitted 1 to
3mm below pupils and that pantoscopic tilt is between 2 and
4-degrees.
Fast, Consistent Tinting
All high-index lenses are sensitive to temperatures above 175ﾰF. To
achieve the best results for a sunglass tint, and maintain
lens-center integrity, we suggest that you lower your normal dye pot
temperature, or submerge the lenses in tint solution for no more
than three-minute intervals, with cooling time in between.
Transitions lenses cannot be tinted, however, they can be AR coated
by quality custom AR coating labs. |
