Low Tg Ball Lens has the characteristics of low melting and softening temperature, being easily shaped and special optical-mechanical properties, easy to be molded by secondary pressing, suitable for precision pressing of aspherical lenses, which helps to reduce the production cost of batch lenses. Low Tg Ball Lens / Aspherical Lenses are applied in precision molding, such as digital cameras, video cameras, mobile phones, etc.
Branded color and plano contact lenses.
Thanks to the use of latest technology generators, which work with a precision of 0.3 microns, this lens has the ability to offer a more precise vision in all areas needed, and to compensate for any second level errors. Thus, you get a large area close up, and a sharper intermediate zone by adjusting the actual dioptric measurement that of the prescription more consistently. The lens, which follows all the modern aesthetic standards of internal base flattening, has a variable inset construction, and offers the possibility of modifying the progression channel for each eye. It is, in fact, possible to personalize even further: the morphological and functional differences between right and left handed users. The Progressive Aurora Clear lenses are supplied in two basic designs that cover the most common uses: - Ottima, which ensures maximum amplitude of distant vision, especially peripheral, and is ideal for those who spend most of the day outdoors. - Ampia, which offers a comfortable solution for all situations. To these designs, we have also added Unica, designed to meet the specific needs of the customer through the optimization of specific parameters provided: right or left handed, pantoscopic tilt of the frame, corneal apex / lens distance, angle of winding of the frame and reading distance. All of these factors make it a custom-built lens, specifically for each customer. To the classic progressive geometries, we add the Degressive INDOOR (PC & MEETING) geometries, specially designed to provide all the comfort of aurora technology even to those who spend most of the time in closed in spaces, or simply need a pair of glasses optimized for close - intermediate vision.
The innovative Blue Natural lenses act as a protective filter for the eye, and absorb these potentially harmful light radiations. They protect the eye completely, blocking UV rays and high-energy blue light up to 420 nm, while allowing for normal colour perception. The latest generation BLUE NATURAL lens is a protective filter able to absorb all the light radiations potentially harmful to the human eye. Part of the light of the "first visible", in particular the blue light (400-540 nm), presents characteristics of high energies that can be harmful to the eye such as UV rays. The BLUE NATURAL lens completely shields against light radiation up to 420 nm, blocking UV rays and the part of high-energy blue light, allowing the part of blue light to pass through the normal color perception. The BLUE NATURAL lens is suitable for those who want the highest visual protection in any environment. The harmful effects of blue light: Red and irritated eyes Ocular dryness Blurred vision Feeling of light annoyance Emergence of eye diseases such as keratitis, etc

The damage caused by UV-A rays is cumulative and permanent, and can affect the cornea, the crystalline lens, the iris, the retina and the related conjunctival and epithelial tissues. The NOuv technology lens completely eliminates UV rays up to 400 nm. The potential harmful effects of UV rays are: Ocular dryness and oxidative reactions to the conjunctiva Yellowing and loss of transparency of the lens Damage to the corn Ultraviolet (UV) radiations are in the invisible region of the electromagnetic spectrum, between 100 nm and 400 nm, and they are divided into three bands (UVA, UVB and UVC) based on biological effects. The UV-C rays are absorbed at 100% by the Earth's electromagnetic field; the UV-B rays are absorbed at 95% by the terrestrial and ozone sphere electromagnetic field. UV-A rays affect the eye entirely. We are specialized in optical lenses since 1950s in Italy. Now we have steady productions, research, sales, marketing, after sale care and so on. We have past CE, FDA and some other certificate as for the medical device.

Quartz A grade refer to high-quality quartz that are of the highest grade and purity. This grade typically has a SiO2 content of 99.9% and above, making them suitable for use in industries where high purity is critical, such as in the production of high-quality optical lenses, semiconductors, and other electronics components. Quartz A grade has a particle size ranging from 1mm to 10mm, in the case of Lumps, depending on the specific application. They are carefully selected and processed to ensure that they meet strict quality standards, including low levels of impurities and uniform particle size distribution.
