Mu rwego rwo guhanga udushya mu by'amatara, imiterere y'amatara ishyirwa mu byiciro bibiri: uruziga n'urutare. Amatara asanzwe, aterwa no gushaka uburyo bworoshye bwo kugabanya ubushyuhe, asaba impinduka mu kuzunguruka kw'amatara, bitandukanye cyane n'imiterere gakondo y'ubuso bw'amatara. Imiterere y'uruziga, mbere yari isanzwe, yahuraga n'ihindagurika ryinshi n'ihindagurika. Ibi byakunze gutuma habaho ibibazo bikomeye nko kubona amashusho adasobanutse neza, kureba nabi, no kubona ibintu mu buryo buke.
Ubu, imiterere y’ibara ry’umutuku yagaragaye nk’imbaraga zo gukosora, ikemura neza uku kuntu amaso yangiritse kandi igatanga igisubizo gitanga ama-lenses atari ayoroheje gusa ahubwo anafite uburebure bungana. Icy'ingenzi ni uko aya ma-lenses adatuma ama-lenses adashobora kwangirika cyane, bityo bigatuma ahora agaragara neza.
Indorerwamo gakondo zizunguruka zifite ingaruka mbi cyane - ibintu birebwa hirya no hino ku nkengero z'indorerwamo bisa n'ibidasobanutse neza, bigatuma urwego rw'indorerwamo rugabanya ubushobozi bw'umuntu urwambaye. Muri iki gihe aho ikoranabuhanga rikomeza gutera imbere, indorerwamo zizunguruka - igitangaza nyacyo cy'indorerwamo - zigabanya imiterere y'indorerwamo ku nkengero z'indorerwamo, zigatuma urwego rw'indorerwamo rurushaho kwaguka kugira ngo ruhuze n'ibyo abakiriya bakeneye. Indorerwamo zizunguruka zifite ishusho yoroheje kandi zoroshye, zikongera ubwiza bw'umwimerere n'ubwiza. Cyane cyane iyo zifite imbaraga nyinshi zo kugarura amaso, zigabanya ubukana bw'amaso, bigatuma aba amahitamo meza ku bakoresha bakeneye imiti myinshi.
Ikintu cy’ingenzi kiranga lenses za aspheric ni uko ubuso bwazo bumeze nk'ubuso budasanzwe. Iyi miterere ya aspheric itanga ibyiza byinshi ugereranyije n'indens gakondo z'uruziga:
1. Umucyo: Ifite uburyo bwihariye bwo gusiga, lenses za aspheric zitanga imikorere myiza y'amaso, zituma umuntu abona neza kandi neza.
2. Ihumure: Ryoroshye cyane, hafi ya zose ntizigaragara, lenseri zigabanya uburemere bw'amaso yawe, bigatuma aruhuka kandi adakoresha imbaraga nyinshi.
3. Iyerekwa karemano: Imiterere yabyo igabanya kugoreka kw'ishusho, bigatuma umuntu abona ibintu mu buryo bufatika kandi bunoze.
Ugereranyije lenzi z’umuzenguruko n’iz’umuzenguruko zifite ibikoresho bimwe n’ibipimo byazo, lenzi z’umuzenguruko zigaragara nk’izigororotse, zoroshye, kandi zitanga ubunararibonye bwo kureba bufatika kandi butuma umuntu yumva amerewe neza. Kwitegereza imiterere y’ikirahure cya lenzi ukoresheje urumuri bigaragaza ko urumuri rugaragara muri rusange rugororotse (usibye lenzi zifite imbaraga nyinshi zo kugarura urumuri); lenzi z’umuzenguruko zigaragaza ubunararibonye bwinshi bitewe n’ubunararibonye butandukanye ku buso bwazo.
Impande z'indorerwamo z'indorerwamo gakondo zimeze nk'iz'uruziga ntizisa n'izinini gusa ahubwo zinahindura uburyo ibintu bireba, ikintu kizwi nka "image aberration". Kugira ngo haboneke imiterere yoroheje, ibikoresho bifite "refractive index" nyinshi byakoreshejwe mu gukora indorerwamo. Byongeye kandi, iyo urebye ukoresheje indorerwamo zimeze nk'iz'uruziga, imiterere y'isura y'uwambaye irahinduka cyane. Indorerwamo zimeze nk'iz'uruziga zigabanya ubugari bwo hagati n'ubw'inkombe, bigatuma indorerwamo iba nto cyane, bigatuma indorerwamo igabanya uburyo bwo kunyuranya n'indorerwamo, bityo igatanga ubunararibonye busanzwe bwo kureba.
Indorerwamo za Aspheric zitanga ahantu hagari kandi hatagoramye ku nkengero, hamwe n'ishusho idahindagurika cyane, bigatuma amashusho aba ari karemano cyane. Izi ndorerwamo zikomera inshuro eshatu kurusha izindi zo mu mpande zazo, bigatuma zikwiriye cyane abayambara bakiri bato. Hamwe n'indorerwamo imwe ya -5.00DS, indorerwamo za Aspheric zoroshye kuri 26% kurusha indorerwamo za Aspheric. Ubuso bwazo buto butuma umuntu abona isi mu buryo busanzwe, haba hafi cyangwa kure, bigabanya umunaniro w'amaso mu gihe kirekire.
Ni nziza ku bantu bambara indorerwamo z'amaso bwa mbere, cyane cyane abanyeshuri n'abakozi bo mu biro, lenses za aspheric zigabanya cyane ububabare bwa mbere buterwa no kwambara indorerwamo. Ni ubundi buryo bwiza bwo gukoresha lenses z'amaso, zikoreshwa mu rugo. Lenses za aspheric zisa cyane n'amaso karemano, kimwe n'uburambe bwo gukoresha lenses z'amaso. Ni nziza ku bantu bakunda kudakoresha imiti myinshi, bashaka kwirinda kugaragara nk'amaso mato afite indorerwamo za myopia, bashaka koroshya uburemere bw'indorerwamo zabo, cyangwa bafite ibyo bakeneye bitandukanye byo kugarura ubushyuhe kuri buri jisho.
Indorerwamo za Aspheric zishobora guha indorerwamo zo mu bwoko bwa refractive index index iciriritse isura imwe n’iy’indorerwamo zo mu bwoko bwa refractive index index index, bigabanya imiterere mibi y’indorerwamo no gukorera ahantu hanini hajyanye n’ibyo abakiriya bakeneye byose bakeneye.
