Carrera eyewear

SINCE 1956

The new “Carrera Design” ophthalmic collection (Safilo Group, Padua, Italy) proposes menswear models in acetate, with a rimless, ultra-light profile (mod CA7467). The CARRERA logo is discretely visible on the flat temples in the nuances of ruthenium-aviation, black-red, blue-orange, dark shiny ruthenium, black ruthenium and brown-hazel.
A slim, rectangular design also marks the rimmed frames in steel sheet, with the line of the temples broken by a subtle passage of light (model CA7464).
The color range comes in the discrete shades of gun metal, semi-shiny brown, mat blue, mat black, and mat palladium. Innovative and high-tech, some of the new frames are produced in “Flexolite Memory Metal”, a particular titanium alloy with extraordinary elasticity (model CA7463).
The structure is extremely flexible and may be deformed, bent and twisted, to then re-assume its original shape, without altering and damaging it, in total comfort and absolute freedom.

colors in Winter sports

Colorful and bright, in the 4 Common Revolution, Pseudo Intellectual, Animal and Psychedelic trends, the new collection of snow mask and helmets from the Bollè designer surprises for its
performances and colors, achieved with transfers and decalcomanias.
For the mask, you may choose between the Fathom, Quasar, Nova,Simmer and Boost (children from8-12) models divided according to the features of the 4 lines.There are outstanding high-tech features: Equalizer system (a Gore-tex tablet eliminates damp between the screens), triple density foam, strap-fastening system with the Forestay helmet, P80 Plus/Carbo Glass protective anti-fog and scratch-proof covering and Air Booster aeration system in 3 position.
The latest novelty is the Modulator Vermilon photochromatic screen. Pink in color, thanks to the hydrogen particles, it darkens in only 9 second when exposed to UV rays, and returns to a dark pink when the sky is cloudy. It filters 44% of visible light when light, and 74% when dark.
Among the helmets we choose the Half Pipe unisex models in antiqued leather, Powder and Bliss, with removable earmuffs in fur for the Animal and Twist line for children.

Safilo eyewear collection

The SAFILO DESIGN ophthalmic frame collection (produced and distributed by the Safilo Group, Padua, Italy) for the coming season proposes new models in a contemporary, recherchè style with refined, original shapes and colors, enriched by innovative details.
A decided personality for the acetate frames, with large, rectangular lines. The temples, fitted with spring hinges, are trimmed in the initial part by a contrasting acetate insert. A slim metal tag, engraved with the SAFILO logo, stands out against the classic shades of grey-blue, streaked brown and amber-horn.
A blend of contemporary mood and minimalist spirit, the ultra-light rimless frames in metal also have a rectangular line. The slim temples, personalized by the logo, come in decided color matchings: ruthenium/aircraft, brown/beige gold, black/red, gunmetal/gold, black/silver and grey/black.

Porsche eyewear: high-tech

High-tech materials, elegant, sporty design and artisan workmanship for a new Porsche Design line for men, distributed by Rodenstock.
Ophthalmic model P’8139, in metal and shades of black, palladium and mat blue, has compact, linear lines and the temples are embellished by side inserts in plastic.
Ophthalmic model P’8145, on the other hand, comes in ultra-light titanium with squared lines, a feisty look and highly dynamic color range.
The Porsche Design sun collection proposes two new sports models: P’8463 and P’8457. In the first, the plastic front joins the ultra-light temples in aluminium, the material also used in automobile construction. The end part of the temples, in soft plastic, makes these models highly stable. Colors: red, mat grey, mat black.
Sport and class for the second sun model, in ultra-light titanium, with particularly marked double temples conferring an aggressive look to the mask front. There are three colors available: mat light gold, mat titanium, mat black.

Armani Anniversary

1988. Giorgio Armani makes his debut in the world of Eyewear. It was a veritable revolution which transformed the perception of eyewear, turning into a cult accessory enhancing the face and conferring personality. This major anniversary was celebrated last May at the Armani privè during MIDO with a photographic exhibition featuring the advertising images created by Giorgio Armani in these 20 years. On this occasion, two historic models were revived (a limited numbered series with only 1,020 exemplars of each): GA 63/N and GA 646/N/S, which will become the 20th Anniversary Exclusive Edition.

Optometry: micro-optical effects 6/6

The quantum voidTHE QUANTUM VACUUM, THE TUNNEL EFFECT AND THE DERIVING TEACHINGS

According to the tunnel effect, even the fusion reaction between a DEUTON and a nucleus of TRIZIUM (which is not possible for classical mechanics, which considers the electrostatic repulsion among the nuclei as an insurmountable barrier) has a finite probability of tunneling through the barrier and this causes the fusion of the nuclei.
Hence, the tunnel effect leads us to state that several fusions which are thought to be impossible, in reality become unavoidable.
Through a quantum series of very slow shifts of atoms and nuclear fusions with the duration of 10 days (elevated to 1500 years), a stone left to itself turns into an iron ball, which represents the status of minimum energy for the stone.
Thanks to this conviction, we come to the principle -in the quantum mechanics- according to which all that is not explicitly prohibited is, as a matter of fact, compulsory.

Anyway, being aware of how the human world is influenced by opinion, and keeping in mind what Democritus said, which is: “By convention sweet, by convention bitter,…but in reality atoms and void”, it is useful to immediately highlight that the quantum void is not as that of classical mechanics, according to which void is immutable and totally empty of an observable structure.
The quantum void owns instead really surprising properties that make it look as an elastic changing its shape.
The creation of an electron-positron pair requires the energetic loan of around 1 MeV, hence electron-positron pairs continually appear and disappear in the quantum void with an average life of 10 (elevated to -20) seconds.
Same thing for any particle-antiparticle pair, which on the contrary live for a period of time which is inversely proportional to the particle mass.
Since we do not give up the hope of filling the void that separates us from every other category, we take this reasoning to extremes to find out that, in principle, the void contains pairs made up of a macroscopic object whichever and its antiobject, which is included in the former and replaces the particles constituting it with the correspondent antiparticles (charge conjugation).
The average life of a similar macroscopic pair with a mass of around 100 Kg would be of the order of 10 (elevated to -53) seconds, and it is a fortune that we do not know how to highlight it yet.
If this becomes possible, we could come to obtain the appearance -even ephemeral- of a man-antiman pair from the void.
Should this come true, let’s try to imagine what would happen if the man who has appeared were a citizen who had had unsolved problems due to the discussions among oculists and optometrists!
“Many fusions which are thought to be impossible, in reality become unavoidable”.
In a period like this, when huge attempts are made to find a solution which would allow oculists and optometrists to agree on a common strategy, given that this cooperation would bring greater benefits and safety to the customers, let’s try to take into account the tunnel effect, according to which everything is possible, as long as one has the time to do it.

To put an end to the whole matter, I will paraphrase what Prof. Ronchi said about CONTACTOLOGY during the 1970 AIOC congress, that is:

OPTOMETRY will be of those who will be able to practise!

And I personally add just one hope: let’s prevent these new professions at least form being practised by people who do not know them properly.

Micro-optical effect art5

THE HEBB-SYNAPSE MODEL
Letters A, B, C are used to indicate three neurons which are involved in the process we are interested in. This model is based on the assumption that a synapse between two neurons A and C becomes more effective as more frequently a signal in cell A is followed by a signal in cell C.
If cell C is binocular, whereas B belongs to the dominant eye and A to the the adept one, it is more probable that cell C will fire A than B.
According to Hebb, what happens is that: a synapse between A and C is preserved and even reinforced as long as an impulse in A is followed by an impulse in C, and this fact is more likely to take place if some kind of support comes from the other eye B at the right moment.
For vision, this will happen if the eyes have the same spacial direction. In case the activity in A is not followed by the activity in C, the synapse between A and C will be negatively influenced with time.
For those cases of ambliophia in which the spacial direction is correct and, even if it isn’t, we can adjust it optically, we have decided to apply a stimulator in front of the eyes which allows two graduated signals to arrive to both eyes, taking advantage of the Hebb synapse.
The tool consists of ordinary glasses, which can be worn all the day long and in which two liquid-crystal filters replace the ordinary corrective lenses or are put above them. These filters are guided by an electronic system which allows the two eyes to put into practice independent variations of minimum and maximum transmittance,
even if the total period of time between the beginning and the end of the stimulus remains the same. We measured the stimulation to the adept eye to 100msec and that to the dominant one to 50msec.
Since the total time has been calculated as 150msec, the result will be -if they start together- the stimulation of the dominant eye for the fist 50msec; after that, the adept eye goes on with the stimulation for an additional 50msec or the dominant eye remains in the dark; at the end of the first 100msec both the eyes will remain in the dark for the following 50msec.
During this phase of the experimentation we are looking for a technique that will allow us to quantify the time of stimulation.

Micro-optical effects: the enlarging lensENLARGING LENS

If we ask the question: ‘When does an enlarging lens really enlarge?’, a lot of people think they know the answer.
But, according to what Prof. Ronchi reports in his book “Seven Conversations on the Enlarging Lens”, the enlargement cannot be treated only from the physical point of view; being in part a psychological fact, it varies from one observer to another.
This should lead us to reconsider most of the opthalmic optics with the eyes of a specialist in psychophysiology of vision, if we do not want to come to prescribe optical systems with theoretical enlargements that will never turn into real enlargements which improve the vision.
It is obvious then that we ask: how can the prescription of enlarging systems, made up of either simple lenses or complex systems of lenses, be committed to people who have little familiarity with the enlargement?
We cannot forget that some companies used to treat the glasses for presbyopia as enlarging lenses, so that it was the enlargement to correct presbyopia and not the power of the lens.
If we arrive to this solution, it means that a lot of ignorance has to be fought off!
