The worlds first double-sided aspheric design
technology from SEIKO provides the highest optical performance in a
lens that is lighter, thinner and more comfortable than conventional
spherical and aspheric designs.
Redefining Visual Excitement
•Thinner and lighter with flatter base curves on both sides.
Comparable to 1.74 index lenses.
•Back surface free-form compensation virtually eliminate power
errors, distortion and marginal astigmatism.
•Improved optics over all other single vision lenses with the widest
peripheral vision.
•Ideal for difficult Rx's especially high cylinder.
Introducing Seiko Super MV 1.67, the world's first 1.67 high index
double-sided aspheric single-vision lens from Seiko Optical, the
leader in high index lens design.
Seiko Super MV 1.67 (MaxVue) lenses take advantage of the latest in
free-form lens technology to create the highest standard in terms of
optical performance, thickness, lightness and comfort.
Seiko's double aspheric design creates a thinner and lighter lens,
with flatter curves on both sides.
Super MV's unique combination of low base curve and concave
free-form aspheric design compensates for distortion, peripheral
power error and astigmatic aberration in a balanced manner. The
result is exceptional clarity of vision throughout the entire lens,
with a significant improvement in the effective viewing area of the
lens, especially in prescriptions with high cylinder.
Seiko Super MV lenses provide standard aspheric compensation on the
front surface, which includes a Seiko-exclusive 10mm spherical
fitting button in the lens center for instant patient accommodation.
The free-form back surface provides precise secondary aspheric/atoric
compensation for each individual prescription. The result is
exceptionally wide peripheral vision with stable, comfortable vision
throughout the entire lens.
Super MV is available from +6.00 to -10.00, out to a -5.00 cylinder
(total power of -10.00 diopters), with up to 3 diopters of prism.

Spherical
No Aspheric Compensation |
Conventional Aspheric
Aspheric compensation in the spherical power only |
Super MV
Double Aspheric
Aspheric compensation in the sphere power and
throughout the cylinder power |
|
 |
| In a spherical
lens design, power errors are increased in the
peripheral area of the lens. The effective viewing range
is therefore considerably limited. Spherical lenses are
also thicker and heavier. |
In aspheric
lens design, the aspheric front surface controls
astigmatism and power error in the spherical power,
resulting in wider peripheral areas. Aspheric lenses are
thinner and lighter than spherical lenses. |
In Super MV
lenses, power error and marginal astigmatism in the
peripheral areas of the lens are optimized in the
spherical and cylinder powers, significantly improving
the effective viewing range. |
