Mu guhitamo indorerwamo za muganga, abaguzi benshi bizera ko uko indorerwamo za lens zigenda ziyongera ari ko indorerwamo zigenda zirushaho kuba nziza. Ariko, imikorere y'indorerwamo iterwa n'ibintu byinshi, birimo imikorere y'amaso, ubugari bw'indorerwamo, uburemere, igiciro, nibindi. Gusobanukirwa imiterere y'indorerwamo zifite ibipimo bitandukanye bifasha abaganga b'amaso gutanga igisubizo gikwiye buri wese uyambaye.
Imikorere y'urumuri
Agaciro ka Abbe gapima ingano y'ikwirakwizwa rya chromatic ry'ibikoresho bya lens. Agaciro ka abbe gakomeye bivuze kureba neza kandi nta guhindagurika cyane kw'amabara.
- Igipimo cya 1.50 gitanga agaciro ka Abbe kari hejuru cyane mu bikoresho byose bya lens optique, gitanga ubwiza buhebuje bw'amaso n'uburyo bwo gukwirakwiza chromatic mu buryo budasobanutse neza.
- Muri rusange, ibikoresho bifite index yo hejuru akenshi bisaba gusimbuza uburyo bwo kubona urumuri rw'amabara kugira ngo haboneke lenses ntoya. Ariko, index 1.60 na 1.71 biracyatanga agaciro ka Abbe kari hejuru.
Ku bakoresha imiti mike kandi bagashyira imbere ubwiza bw'amaso, lenzi ya index 1.50 irasabwa cyane.
Ubunini n'Uburemere
Ubunini n'uburemere bw'ikirahuri ni kimwe mu bitandukanya ibikoresho cyane.
- Igipimo cya 1.50 na 1.56 bitanga ubunini busanzwe n'uburemere busanzwe.
- Igipimo cya 1.60 na 1.67 bitanga indorerwamo nto kandi zoroheje, binoza imiterere y'ubwiza cyane cyane ku bakinnyi basanzwe cyangwa abakoresha imiti yo mu bwoko bwa “nurse”.
- Urutonde rwa 1.71 na 1.74 rutanga lenzi nto kandi yoroheje, bigatuma ziba nziza cyane ku baganga baguzwe imiti myinshi.
Uko index yiyongera, lenses zigenda ziba nto kandi zoroshye, bigatuma ubwiza bw'amaso burushaho kuba bwiza ndetse no gutuma umuntu amererwa neza.
Igenamiterere ry'Ibiciro
Igiciro ni ikindi kintu cy'ingenzi mu guhitamo lens. Muri rusange, index iri hejuru iza n'igiciro kiri hejuru, nubwo hari itandukaniro.
- Igipimo cya 1.50 na 1.56 bishyirwa mu byiciro nk'ibisubizo bihendutse ku isoko. Ariko ikiguzi cya 1.50 kiri hejuru ya 1.56.
- Igipimo cya 1.60 na 1.67 bigaragaza igice cyo hagati kugeza ku cyo hejuru, kiringaniza imikorere n'ubushobozi bwo kwishyura.
- Igipimo cya 1.71 kirahenze cyane, ariko kirahendutse cyane kurusha 1.74.
- Index 1.74 ni amahitamo meza cyane yagenewe imiti ikoreshwa mu mashanyarazi menshi cyane no mu makusanyirizo y’amatara meza cyane.
Umwanzuro
Nta gipimo kimwe cy’indorerwamo kibereye buri wese uyambaye. Ahubwo, igisubizo cyiza ni ikijyanye n’ibyo umuntu uyambaye akeneye mu maso. Uretse ingingo zavuzwe haruguru, ibintu nk'ingano y'indorerwamo, imiterere y'indorerwamo, intera y'indorerwamo, n'imiterere y'indorerwamo, kuko byose bishobora kugira ingaruka ku bunini bwa nyuma bw'indorerwamo, uko isura, n'uburyo umuntu yambara neza muri rusange.
Nk’uruganda rw’inzobere mu gukora lens z’amatara, dutanga urutonde rwuzuye rw’ibipimo by’amatara biri hagati ya 1.50 na 1.74, hamwe n’amahitamo atandukanye yo gusiga, photochromic, na lens zifite ibara ry’umutuku. Dutanga amahitamo menshi y’ibisubizo by’amatara, dufasha abafatanyabikorwa bacu ku isi guhaza ibyifuzo bitandukanye by’isoko mu gihe twemeza ko buri wese uyambaye ashobora kubona lens ijyanye n’ibyo akeneye ku giti cye.
