To have one’s lenses correctly centered on a frame, it is usually required what is generally defined as Pupillary Distance (PD), which is the distance -expressed in millimetres- between the centers of each eye’s pupils. This definition, however, is too general and does not clearly explain the meaning of this essential measurement. To be more precise, we should speak of Pupillary Distance (PD) and Distance between the Visual Axes, which are very similar and are usually considered as the same; actually, these measurements hardly ever correspond and are both really important for the proper fitting of one’s lenses on the glasses (see picture below).
DAV = Distance between Visual Axes.
DI = Inter-Pupillary Distance.
What is the difference between the Pupillary Distance and the Distance between the Visual Axes? The former is measured by referring to the pupillary centers of each eye, while the latter is measured by taking into account the corneal reflection produced by a light source directed to the eyes. The corneal reflection is almost ever nasal in regard to the pupillary center; as a consequence, the Distance between the Visual Axes will result a bit smaller than the Pupillary Distance.
If you want the center of the lens to be perfectly in line with the center of your eye, the measurement to take into consideration should be the distance between the axes and not the pupil one although, as we have just seen, these measurements are really close. Besides, some kinds of progressive lenses exist which, on the manufacturer’s instruction, must be centered on the frame by referring to the PD.
Several are the methods or the tools which can be used in order to find out both kinds of distance, such as the inter-pupilometer, a tool which measures the visual axes distance and is mostly used by optometrists, opticians and optics.
LENSES USE AND MANTAINANCE.
Our progressive lenses ‘Multifocal Advanced’ are realized with a new technology Free-Form where the progressive chanal is developed on the inside of the lenses and not on the outside as for traditional progressive lenses.
With the realisation of progression on the inner surface, the variation of power is more close to the corneal apex and has the effect of minor aberration and consequently an enlargement of the visual field having equal quality of costruction and material as traditional lenses.
Our ‘Multifocal Advanced’ lenses with technology Freeform, are giving the guarantee for a 40% better visual performance compared with traditional progressive lenses beeing the result of a double production process: curves of progression on the outer surface and corrective power for ametrophy on the inner surface.
Using a software of last generation the technology Free-Form allows also to realise an inset (orizontal shifting of the near visual field compared to the far visual field) not only variable with addition but also in function of personal parameters.
The ‘Multifocal Advanced’ lenses with technology Freeform are realized with FULL TOP treatment.
Having antireflex multilayers treatment on the surface and hardened with 6 layers they are very resistant against scratches. Realized also with dust and water repellent treatment on both surfaces. The FULL TOP treatment is having a transmission of more than 99,5% making the lenses extremely transparent.
GO XTRA DARK. The new lenses Transitions XTRActive are the darkest dynamic Trasition lenses; in full sun they are quickly adjusting to the darkest of traditional sunglasses: 90% of tint at a temperature of 23 degrees. Transitions XTRActive darken even faster and at higher temperatures: 80% of tint at a temperature of 35 degrees. XTRActive Transitions lenses reduce glare, optimize vision, enhance eye comfort and they continuously adapt to changing light in all conditions of sunlight and temperature and of course, fade back indoors, keeping a confortable slight indoor tint.
They are the first dynamic trasitions lenses turning dark inside the car and by sensing and adjusting to visible light as well a UV light they activate a comfortable level of tint for driving, up to 50% at a temperature of 27 degrees. (The fact that XTRActive Transitions lenses darken behind the windshield of a car is influenced by many factors including the shape, the angle and the transmittance of the windscreen, the side windows and the driver’s position)
Drivewear lenses are capable of sensing and reacting to varying light conditions both outside and behind the windshield of the car. Drivewear lenses provide the wearer with the appropriate visual solution for all weather conditions, from bright sunlight accompanied by intense, blinding glare, to overcast bad weather conditions. Drivewear lenses protect the eyes form glare through polarization and enhance and protect vision through photochromics which respond to both visible and UV light.

Ophthalmic 8-based lenses, carried out through Overcut technology, have been especially thought for those who like wrapping shapes for both eyewear glasses and sunglasses, either because they play outdoor sports or because love to follow the latest trends. Overcut is an innovative and revolutionary computerized workcentre with digital check, thanks to which precision becomes “Absolute”; it also allows the fitting of ophthalmic lenses in any type of sunglasses. It is Overcut exclusive prerogative to be able to measure the thickness of the just-cut lens with millimetric precision and above all to be able to measure and visualize the spatial expansion of the surface, which will be chamfered. With overcut, the technical features of the shaping will perfectly fit into modern frames.
– Subtle cello/acetate sunglasses can house negative lenses without deforming the frame, avoiding the consequent widening of the lenses.
– We can make 8-based glasant keeping the perfect shaping of the lenses, as well as the inclination of the puncturing angle required by the front and the bridge.
– The edges of nylor fittings will be reproduced with extreme precision, leaving the charming designs of the most prestigious frames unchanged.
– Wide 8-based glasses will have shaped lenses with a so precise chamfer as to follow exactly the frame profile without causing the unaesthetic coming out of the eyebrows.
Anti-reflex: All Hi-Sun lenses with Overcut technology are provided with anti-reflex treatment on the inner surface of the lens itself, in order to make it more effective in situations of high reflection, such as during outdoor sport activities: the anti-reflex membrane has seven layers for each surface, and is resistant to abrasions and waterproof.
When the degree of envelopment of the sunglasses make it necessary, dioptric strenght is recalculated taking into account the panoramic inclination and the interpupillary distance. The calculation algorithm has been reckoned in collaboration with: Padova University of Studies, Laboratory for Ultraviolet and X-ray Optical Research, National Council for Research.
Hi-Performance 1.74 Aspheric is the thinnest organic material, which is available in the current market; The Hi-Performance 1.74 lense, such as the Essilor Lineis 1.74, has been created in particular to satisfy the esthetic and comfort needs.
This material is particularly suggested for all users, who are very carefull at the esthetic aspect and at the quality. It is also suitable for high diopters. The advantage of Hi-Performance Aspheric 1.74 is a lense with high index in elastic organic material, which is distinguished by an high visual performance.
