Don't compromise when it comes to protecting your eyes. Twins Optical sunglasses feature polarized lenses, which play a central role in the quality of sunglasses when it comes to UV protection.

Choose from the different sunglasses from Twins Optical. Many models, colors and types of polarized lenses (classic, mirrored or gradient) and enjoy the unbeatable combination of high quality at very competitive prices of our sunglasses.

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

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

Twins Optical is therefore one of the few brands that have both certifications necessary to guarantee the quality of its products, demonstrating that it truly cares about the concept of medical devices.

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, in the control of lenses, the use of professional and technologically advanced equipment, such as electronic Frontifocometers, allows you to be sure that any imperfection is highlighted immediately. Lenses that do not correspond 100% to the quality requirements are first discarded and then destroyed.

ESSENCE OF A UNIQUE PIECE

Whenever we talk about testing procedures for glasses, the first factor that inevitably comes into consideration is the strength of the welding between the frame and the lenses. Glasses are delicate objects that undergo various stresses due to the use we make of them; just think about 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 glasses are a single piece, welded to perfection.

HEAT-PROOF FRAMES

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

GLASSES THAT DON'T DEFORM

Mechanical tests start from what is called dimensional stability at high temperature. By examining the distance between the ends of the frame temples, the ability of the polymers to maintain their measurements when environmental conditions vary is evaluated.

SWEAT RESISTANT FRAMES

Glasses, as we all 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 double-distilled water. Through this procedure, it is possible to observe how the glasses react, in terms of color, with stains or changes in tone. This is the reason why the test is repeated several times.

THE IMPORTANCE OF LENS STRENGTH

The lenses are perhaps the most important part of a good reading glasses. Our products are subjected to the mechanical strength test 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 the certification by Certottica. Thanks to these tests we are sure to offer quality glasses, able to resist the mechanical stresses and environmental impacts to which they are constantly subjected when they accompany us during our days.
