In this Series the innovative Dual System allows you to wear the glasses alternately with a Back Fixing or with the Terminals / Temples: both modes are adjustable. In the new FLASH models the contact points on the face have been reduced and a wide and free ventilation has been configured. They result therefore less specific for example for an esclusive use in motorcycle or in conditions of strong wind, but they are lighter and suitable in situations of strong heat for example in summer for sunbathing. All ONIRS frames, if slightly dampened, release an exclusive, unique and very pleasant sensation of freshness for several hours. The new temples compensate for the characteristics of the new lighter structure, giving it perfect stability and an optimal trim. The new system also allows adjustment, without detaching them from the frame.
