Introducing Seiko Super MV 1.67, the world’s first 1.67 high index double-sides aspheric single vision lens from Seiko Optical, the leader in high index lens design.
Seiko Super MV 1.67 (MaxVue) lenses takes 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 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.
Spherical Lens Design:
In a spherical lens designs, power errors are increased in the peripheral are of the lens. The effective viewing range is therefore considerable limited. Spherical lenses are also thicker and heavier.
Aspheric Lens Design:
In aspheric lens designs, 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.
Seiko Super MV Design:
In Super MV lenses, power error and marginal astigmatism in the peripheral area of the lens are optimized in the spherical and cylinder powers, significantly improving the effective viewing range. The lens has an aspheric design on the front surface, precise secondary free-form aspheric compensation on the back surface and a 10mm spherical fitting button. The result is optimal performance in each and every prescription. |
