Double asphericity is not a new concept. It offers improved optical performance over conventional aspheric lenses for astigmatic prescriptions. However,Nikon Seemax brings double aspheric techology to a new level.
SeeMax incorporates an extra 6 aspherical axes into the back of the lens, allowing optical performance to be maximized at every gaze angle.
Conventional Aspheric Lenses have an aspheric design on the front surface only.The lens is flatter, and oblique astigmatism and power error are better controlled than in spherical lenses.However when the presciption includes a cylinder, the design can only optimally control aberrations in one of the 2 principal meridians.
Conventional Double Aspheric Lenses have an aspheric axis on the front and 2 aspherical axes on the back surface. This allows for a level of improvement over aspheric lenses, yet distortion still exist in some areas of the lens.
SeeMax is a multi-directional double-aspheric lens.An extra 6 aspherical axes are incorporated into the back of the lens to optimise optical performance across the entire lens surface, thus reducing aberration in multiple meridians.
Customized to the frame shape and prescription
The visual performance is enhanced according to the frame
shape chosen. This is achieved with Nikon Optical Design
Engine (NODE), Which improves performance within the
useful zone of the lens corresponding to the frame shape.
NODE system is an automatic design calculation programme. It
continuously redesigns each evaluation point until the whole
surface falling inside the frame shape is optimal in terms of
acuity. This ensures accurate powers even in the lens peripihery.

Ideal for
For any ametrope (spherical or astigmatic prescription) and especially:
For those experiencing difficulties levels of visual performance from their single vision lenses.
For those experiencing difficulties with regular single vision lenses (especially contact lens wearers who need accrurate vision with their back-up spectacle lenses).
For astigmatic prescriptions greater than-1.00D cyl.
For those wearing their spectacles for long periods of time.

Sand Eraser test: lens rubbed 100 times with a send paper and pressure of 1kg.
Nikon SHE99 includes a built-in double-sided coating that reinforces the lens surface. It ensures maximum protection against scratching and peeling.
Effortless to Clean
The improved top coat makes the surface so slippery that water beads right off, making your lenses so much easier to clean. Fingerprints, facial oils, and smudges can now be removed effortlessly.
