Hauv qab no peb yuav tham txog cov khoom siv feem ntau siv, acetate tsom iav thav duab, titanium iav thav duab, TR90 iav thav ntawv thiab cov tsom iav alloy.
Acetate iav tsom iav:
Qhov zoo: kuj ruaj, tsis yooj yim rau deform, anti-allergic. Lub ntug ntawm lub spectacle thav duab muaj zog occlusion, zoo nkauj tsos, thiab nws kuj yog heev fashionable hnav. Qhov kev ntxhib los mos muaj zog dua.
Qhov tsis zoo: tab sis feem ntau tsis dhau lub teeb, nias tus choj ntawm lub qhov ntswg.
Titanium Frames:
Qhov zoo: Lub purity ntawm titanium nce mus txog ntau dua 89 feem pua. Sturdy thiab ruaj, ultra-lub teeb, zoo kev ntxhib los mos, corrosion kuj, hypoallergenic, nws yog kev noj qab haus huv ntawm cov neeg uas nrhiav lightness. Nyiam los ntawm cov neeg ua lag luam.
