Winkoko gukurakugeza kuri 40+ ,.lens ya kristaline ibaumuhondo naibicu, aho tuzabura imbaraga zo gutandukanya ibintu byizabikabijen'amabara gahoro gahoro. Ku bageze mu za bukuruabantuababona binyuze mumurongo wamabara ya kristaline ukoresheje icyatsi kibisi, biragoye kumenya ibara ritukura nicyatsi kuko urumuri rwumuhondo rukomera cyane. Kubera iki1.60 UV585nikunoza icyerekezokuberako umutuku n'icyatsi birashobora kugaragara neza mugukata itara ry'umuhondo.
Kugaragara kw'abasaza bo hagati ni "Umuhondo Reba" Kugereranya ibintu byumuhondo (ibumoso) nibisanzwe (iburyo)
Umuhondo ni ibara ryuzuzanya ryablue. Itara ry'umuhondocut isgushobora guhindura ibara.
