Mbere, mugihe uhisemo lens, abaguzi mubisanzwe bashyira imbere ibicuruzwa mbere. Izina ryabakora lens nini akenshi ryerekana ubuziranenge no gutuza mubitekerezo byabaguzi. Ariko, hamwe niterambere ryisoko ryabaguzi, "gukoresha ibinezeza" no "gukora ubushakashatsi bunoze" byahindutse imico yingenzi kubaguzi b'iki gihe. Abakiriya rero bitondera cyane ibipimo bya lens. Mubipimo byose bya lens, Abbe agaciro ningirakamaro cyane mugihe usuzumye lens.
Abbe agaciro ni igipimo cyurwego urumuri rutatana cyangwa rutandukanijwe iyo runyuze mumurongo. Gutatanya bibaho igihe icyo aricyo cyose iyo urumuri rwera rumenetse mumabara yibigize. Niba Abbe agaciro kari hasi cyane, noneho urumuri rutatanye ruzatera chromatic aberration igaragara mubyerekezo byumuntu kumera nkumukororombya uzengurutse ibintu bigaragara cyane cyane hafi yumucyo.
Ikiranga iyo lens ni uko hejuru ya Abbe agaciro, niko optique ya periferique izaba nziza; munsi ya Abbe agaciro ni, aberration ya chromatic izaba. Muyandi magambo, agaciro gakomeye ka Abbe gasobanura gutandukana gake ad iyerekwa risobanutse, mugihe agaciro ka Abbe gake gasobanura gutatanya cyane hamwe nibara ryinshi. Iyo rero uhisemo optique ya optique, nibyiza guhitamo lens hamwe nagaciro keza Abbe.
Hano urashobora kubona Abbe agaciro kubikoresho nyamukuru byinzira ku isoko:
