Digi-Contour technology has resulted in numerous lens advancements and stands to be one of the most dynamic technological innovations in the manufacturing of eyewear.

For the first time, the wearer can actually receive a corrective lens designed especially to accommodate his or her exact prescription.

High contrast image with wider field of vision - upto 30% compared to conventional lens. Remarkable clear image without distortions in the peripheral areas due to less astigmatism.

Based on the series of contour plots from various PALs available, and by calculating the mean deviations, each design has been produced with region-wise contour plots.

With advanced design calculations, it is possible to adjust the mean deviation of Nova Lifestyle Series Lenses to the better acceptable limits with perfect balance of Distance, Intermediate and Near Vision Zones.

In order to achieve the maximum clarity in the peripheral zone of the lens, the spherical and cylindrical power meridians are aspherized.

With Multi Aspheric Technology, it is possible to reduce the distortions associated with both the spherical and cylindrical power meridians by using a non-rotational symmetrical surface, in which the asphericity varies from meridian to meridian.

It provides unrestricted fields of clear Vision.

With the help of Aberration filter system, it is possible to compensate the oblique aberrations according to the tilt of the lens.

It allows much better compensation of the oblique aberrations by controlling the relative curvature changes through creation of arbitrary surfaces.

In other words, it is possible to optimize the lens for all gazes, according to the visual requirements of each person.

The lenses with one of the least aberrations in the market

It considers the real shape of the frame and uses a unique algorithm to clean the Useful area of the lens.

A progressive lens with a level of aberrations between 15% and 40% less than a standard progressive lens

Binocular Balancing technology balances the level of astigmatism on both sides of the corridor making the amount of blurriness perceived by each eye similar, and reducing it to the minimum, thus improving binocular vision and providing a greater visual field, especially in intermediate and near vision zones..

It is the power-based balancing method, where the differences in Addition powers at the position, where the line of sight passes, are reduced, and the vision is corrected with less blur and greater balance.

The image received by each eye is nearly same in terms of clarity and distortions produced within the corridor and peripheral zones.

Standard Freeform

CRIB is the pre-calibrated lens (rounded or oval) better adjusted to the real frame shape.


Rx: +3,00 sph+2.50 cyl175o, add 2.00

When we apply a pre-calibration in a Free Form lens, we get an edge thickness of 0.5 mm in the pre-calibrated lens (crib). Not in the beveled lens (real frame shape)

Slimtech Technology

How can a plus lens reduce its center thickness when the edge thickness is the limit? using the frame data in the optimization algorithm

Rx: +3.00Dsph/+2.50Dcyl X 175°, Add 2.00Dsph

Slimtech is able to overcome this limitation in Free Form manufacturing by modifying the surface out of the useful zone and achieve the maximum thickness reduction possible.

A Slimtech Design has a dynamically contoured vision zone, thanks to the Patented Algorithm of Design. This makes the lenses look aesthetically better while maintaining the best visual performance.

+ Reduced thickness of lenses makes them look even better in any type of frame.

+ This process makes it possible to reduce the visible edge thickness of spectacle lenses to a technically feasible minimum.

+ Lens design creates the perfect balance between visual performance (function) and thinner lenses (fashion).

+ The SlimTech thinning algorithm assures the thinnest lens possible for a fashionable appearance (nearly 40% of thickness reduction)

+ Customized Design with Lens Power Compensation for 'position of wear' This design takes into consideration the customer's lens prescription and frame parameters to optimize the best visual solution.

+ Due to the tilt angle, optical axis is distorted. Power error and prism are generated.

+ Once the frame angle, tilt, lens base, fitting height, prescription are known, then a compensation for the axis can be made. The actual lens surface is calculated (compensated) to take all of these calculations into account.

With Slimtech technology, it is ensured the maximum optimization of center and edge thickness without damaging the polishing pads
