Nova UHD – Innovative Progressive Lens

Nova redefines visual clarity with its latest innovation in PAL category. Nova UHD is certain to change the choice of lenses for the 40+ population…   

NOVA: The globally acclaimed brand from the house of Vision Rx Lab, presents their latest innovation in PAL category, Nova UHD, a custom designed lens for exceptional visual clarity. The major optimizing technologies that make Nova UHD the ideal choice of lenses for the 40+ population are highlighted here.

MULTI ASPHERIC TECHNOLOGY

Asphere

It is possible to reduce the aberrations associated with both the Spherical and Cylindrical Power elements on numerous meridian by using non-rotational symmetrical surface, wherein the asphericity varies from meridian to meridian to provide unrestricted & substantially wider fields of clear vision.

ABERRATION FITER SYSTEM

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

MAXIVIEW DESIGN

By considering the real shape of the frame and using a unique algorithm, the distribution of aberrations is modified and reduced within the useful area of the lens.

BINOCULAR BALANCING SYSTEM

Binocular Balancing System balances the levels of astigmatism on both sides of the corridor and reduces them to improve binocular vision and provides wider visual fields.

DIGITAL PROFILE

It ensures a comfortable posture for near vision based on the consideration of today’s visual needs and user ergonomics. With this technology, longer vertical area with 100% of the Addition is offered to the wearers which helps in better adaptation and comfortable vision while reading & using digital devices like smartphones, tablets, laptops etc.

OPTIREAL

Optireal takes the user’s position of spectacle wearing parameters into account & obtains a personalized correction for the lens that fully adapts to the user’s wearing habits & delivers the exact effect of the clinically availed refractive correction.

VARIABLE MFH & NEAR INSET

Nova UHD provides the optician with the option of variable minimum fitting height & near inset. This provides the option to choose from in virtually all shapes and sizes of frame while allowing the best visual experience.

SLIMTECH – THE PATENTED TECHNOLOGY

Slimtech is an exclusive and patented technology for thickness optimization

 

UNDERSTANDING THE SCIENCE BEHIND SLIMTECH:

Standard Freeform

THE EDGE THICKNESS LIMITS THE CENTRE THICKNESS

Example Rx: +3.00 Dsph/+2.50 Dcyl
Axis 175°, N.add+ 2.00Dsph

When we apply a pre-calibration in a Free Formlens, 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

A plus lens can reduce its center thickness (when the edge thickness is the limit) by using the effective frame data in the optimization algorithm by modifying the surface outside the useful zone to achieve the maximum thickness reduction possible.

Slimtech Design has a dynamically contoured vision zone which makes the lenses look aesthetically better while maintaining the best visual performance.

Example Rx: +3.00 Dsph/+2.50 Dcyl Axis 175°, N.add+ 2.00Dsph

With Slimtech technology, maximum optimization of center and edge thickness is ensured.

LIFESTYLE PERSONALISATION

Nova UHD incorporates three different designs for varying requirements based on power details, frame details, wearing parameters and lifestyle. It automatically selects the design best suited for the wearer’s visual priorities. It also effectively reduces a portion of the unwanted swim effect that annoys the wearer while scanning from one area of the lens to the other by high order mathematical calculations.
