Iiglasi zelanga I-No. 2 sisipili sezinye iiglasi zelanga eziyilelwe ukunyamezela nokukhululeka. Isakhelo senziwe kwintsimbi engagqwaliyo yaseJapan enomthamo wememori yobume, ecinana kancinci kangange-0.5 mm, eyilwe ngokugoba nokugoqa ngaphandle kokudibanisa okutshiselweyo okanye izikrufu. I-hinge etshixayo engenazikrufu, elindele ilungelo lobunini bezobuchule (patent-pending), ithatha indawo yezikrufu ezimeleyo kunye nee-hinge zesitya, ngoko ke ii-hinge azinakukhululeka kwaye izikrufu azinakuwa. Isakhelo sinobunzima obuziigram ezili-18. Iilensi ze-polycarbonate ziyakwazi ukumelana nokubethwa kwaye zivimba ukukhanya kwe-ultraviolet. Ii-nose pads kunye neencam zee-temple ezenziwe nge-silicone yomgangatho wezonyango azibangeli ii-allergy.
