Pupillary Distance

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.


DAV and DI


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 Maintenance


  1. When the frame is on, a special care is recommended; avoid to practice activities which could cause it to break and put at risk your safety. Glass lenses are more likely to be broken, causing the production of spiky slivers. Plastic lenses, althoug well resistant to collisions, are not shatterproof. The chance of breaking increases in case of treatments which weaken the lens structure (holes).
  2. Choose with care the most appropriate material for your lenses, according to your daily activites (both sports and working ones).
  3. Check your glasses with an optician/optometrist in case of falls, collisions or other events that could compromise the integrity and the funcionality of the Medical Device.
  4. Even though provided with photochromatic lenses or colouration treatment, corrective lenses are not adequate for the direct observation of the sun or of other potentially dangerous light sources (e.g. electric arches).
  5. Opthalmic lenses are divided into 5 transmission categories. Customers must be informed about the transmission category of the lenses which are fitted on their glasses.
  6. Wear sunglasses following the suggestions of the present list (limitation in use) or suggested by an optician/optometrist, in order not to alter, under particular light conditions, the visual perception.
  7. The darkening of the photochromatic lenses is influenced by different physical and environmental parameters, which vary according to the situation. Under some conditions (e.g. inside a car in summer) it is normal for the darkening capacity to be inferior to that found at purchase time.
  8. Keep your glasses inside their case and avoid to put them, once taken off, upside down on a surface that could damage the lenses.
  9. Avoid the contact between lenses and chimical solvents such as hair-spray, acetone, and so on.
  10. Do not leave your lenses near direct heat and/or steam sources (for example, do not leave your glasses on your car dashboard).
  11. To clean the lenses, use soft clothes wet with water or cleansers with neutral PH, avoiding abrasive clothes and aggressive cleansers. Before dry-cleaning the lenses, using just a cloth, it is advisable to verify the presence of dust compounds or grains which could scratch the lenses during the cleaning, especially if provided with Anti-reflex treatment.

Free-Form Tecnology for multifocal lenses

Progressive lenses

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.

Transitions XTRActive Lenses

Transitions XTRActive

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)

Drive Wear Lenses

Drive Wear: new lens category, available on

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.

    High Contrast Green/Yellow Color. Designed to maximize useful light information reaching the eye. POLARIZED to remove glare that would otherwise DESTROY vision in low light conditions. This color has been thought in order to maximize the total information to the eyes’ visual receptors at low lighting/overcast conditions. The high contrast polarizer works in every lighting condition to remove blinding glare and inhance visual acuity.
    Copper Color. Designed to block out exceeding light and to enable the spotting of road signs, pointing out red and green colors. POLARIZED to block out blinding glare and have optimum visual acuity for safe driving. One of the characteristic features of Drivewear is that they are the only photochromatic lenses that darken behind the the windshield of the car. If exposed to sunlight, the Drivewear lenses turn into a copper color which many consider the best color for a driving . This should not surprise, as Drivewear color has been thought to remove exceeding light and to allow the driver to provide good traffic signals recognition.
    Dark Reddish/Brown Color. Designed to maximise filtration of excess light so that the eye does not get satured. POLARIZED to provide maximum comfort in high light conditions. In outside conditions, Drivewear lenses is activated by visual and UV light and turn into a dark red/brown color. This color has been designed in order to provide maximum filtration of exceeding light and provide the best protection from intense sunlight and blinding gare. Brown lenses allow an excellent spotting of the colors, ponting out especially green colors. As green is the most common color in nature, its emphasising represents an extraordinary visual experienxce.

Genesis of Drivewear. The story of lens evolution from ancient times to the present.

  • Overcast – Low light conditions.
    In low light conditions, Drivewear lenses provide a high light transmission maximalizing the number of informations reaching visual receptors of both eyes. The result is the best possible visual acuity in these conditions of low lighting conditions. In this state, the molecule allows all visible light to come through the lens. High contrast polarized removes glare, which otherwise would destroy vision in low light conditions. In this state, Drivewear lenses block 100% UV A and UV B light. This is one advantage of being Activated by Transitions(TM). Drivewear lenses turn into high contrast green/yellow color. Obviously, there are no better lenses to face overcast or low light conditions, both outside and inside a vehicle.
  • Bright light – Behind the windshield.
    In bright light conditions behind the windshield of a car, Drivewear lenses provide lower overall transmission to control light intensity for optimum visual acuity. Drivewear lenses promote preferential activation of the eye’s red cones (and to a lesser extent, green cones). The result is the best possible vision at these higher light levels. Drivewear’s high contrast polarizer is absolutely essential behind the windshield of the car, because it blocks out blinding glare, one of the most dangerous of all driving hazards.Under these conditions, the Drivewear lenses turn a copper color which many feel is the optimum color for a driving lens. This unique behind-the-windshield response protects against bright light and glare and provides better sensitivity to the “visual signal” that is vital for safe driving.
  • Bright light outdoors – Outside intense light conditions.
    In outside bright light conditions, the eyes’ visual receptors, the rods and cones, can easily get “overpowered” and “oversaturated” with light. The Drivewear lens is designed for maximum filtration of this excess light. Under these bright outside conditions, it achieves its maximum dark color. Here again, it is important to provide maximum protection from blinding glare, and only polarized lenses can do this. Drivewear is designed to provide maximum comfort to the wearer in these high outdoor light conditions.

Ophthalmic 8-based lenses

Overcut TechnologyHi-Sun Overcut
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.
