Twins Optical has always been attentive to the fundamental motto "100% Quality".

First of all we wanted to certify our company according to the worldwide recognized standards UNI EN ISO 9001:2015 | UNI EN ISO 13485:2016 . In addition, Twins Optical eyewear we have certified our eyewear at CERTOTTICA (Italian Institute of Optical Product Certification).

Twins Optical is therefore among the few brands that have both certifications necessary to guarantee the quality of its products, demonstrating that they really care about the concept of medical devices.

Reading glasses for simple presbyopia are in fact Class I Medical Devices and can only be manufactured by authorized structures and laboratories.

But that is not all. We are never satisfied, to guarantee you the highest quality and safety in our products.

Mast Industria Italiana, to ensure that the TWINS OPTICAL brand is the best choice for the public, has entrusted a team of professionals with the control of each single eyewear product, before placing it on the market. Using highly professional electronic equipment, i.e. Lensmeters, the product is analyzed on the basis of:

the power expressed in diopters;

the interpupillary distance.

Subsequently the check passes under the watchful eye of the professional, who certifies:

the quality of the surface, both of the frame and of the lens itself;

the flexibility system of the temples, in the models equipped with the Flex System.

Frame, temples, lenses: all the components of our glasses are meticulously checked one by one before delivery to the pharmacy, to guarantee you a top quality product without the slightest imperfection. In particular when checking the lenses, the use of professional and technologically advanced equipment, such as electronic lensmeters, allows you to be sure that any imperfection is immediately highlighted. Lenses that do not meet the quality requirements 100% are rejected first and then destroyed.

ESSENCE OF A UNIQUE PIECE

Whenever we talk about eyewear testing procedures, the first factor that inevitably comes into consideration is the strength of the weld between the frame and the lenses. Glasses are delicate objects that undergo various stresses due to the use we make of them; just think of how many times, during the day, we take them off and put them back on. If the elements that make up the glasses are not welded together with sufficient strength, the risk is that the lenses detach from the frame. It is important that the eyewear is a single piece, welded to perfection.

HEAT PROOF FRAMES

The eyeglass frame has to withstand various environmental conditions, including heat. A series of tests are carried out to evaluate the response of the frame to contact with, or proximity to, a heat source. During this type of test, incandescent metal is approached in order to evaluate whether the eyeglass frame itself generates combustion or resists the heat source. If the frame, during or in the time immediately following contact, does not in turn generate combustion, the ignition and flammability test is passed.

GLASSES THAT DO NOT DEFORM

The mechanical tests start from what is defined as dimensional stability at elevated temperatures. By examining the distance between the ends of the temples of the frames, the ability of the polymers to maintain measurements under varying environmental conditions is evaluated.

SWEAT RESISTANT FRAMES

Glasses, as we well know, are constantly in contact with the skin when we use them. The sweat resistance test is performed by immersing the frame in a solution of lactic acid, sodium chloride and bidistilled water. Through this procedure it is possible to observe how the eyewear reacts, from the point of view of colour, with spots or changes in tone. This is the reason why the test is repeated several times.

THE IMPORTANCE OF ROBUSTNESS OF THE LENSES

The lenses are perhaps the most important part of a good reading eyewear. Our products are tested on the mechanical strength of the lenses to verify the resistance to the stresses to which we subject them during the day. All Twins Optical eyeglasses are also subjected to other accurate and meticulous mechanical and optical tests in order to obtain certification from Certottica. Thanks to these tests we are sure to offer quality eyewear, able to withstand the mechanical stresses and environmental impacts to which they are constantly subjected when they accompany us during our days.
