Agace ka kabiri k'imikorere iherereye hafi yimpande zo hepfo ya lens. Agace kegereye urwego ni impamyabumenyi yo kubona hafi, ikoreshwa mu kubona ibintu byegeranye.
Agace ka gatatu gakorwa nigice cyo hagati gihuza byombi, cyitwa Gradient Agace, buhoro buhoro kandi gahoraho kuva kure kugeza kuri hafi, kugirango ubashe kubibona.
Kuva hanze, amabuye yinshi yijimye ntabwo atandukanye ninzira isanzwe.
02Ingaruka zo Gutera imbere
Lens nyinshi zimaze gutera imbere kugirango zitange abarwayi hamwe na preskopia hamwe nuburyo busanzwe, bworoshye kandi bwiza bwo gukosorwa.

Icyitonderwa: Nkuko abarwayi benshi bayopia bafite oblique yo hanze aho kuba oblique yimbere, umubare wabantu ubereye kwambara ibirahuri byinshi bitera imbere kugirango bigenzure Iterambere ni bike, kubara kuri 8% gusa byayopia.
Lens Lens irashobora kandi gukoreshwa muguhagarika umunaniro kubantu bato nabasaza. Nkumugongo wa societe, umunaniro wijisho ryumusore nabanyeshuri bo hagati birakwiye kwitabwaho. Lens Lens irashobora kuba isa na lens ya anti-umunaniro kugirango igabanye umunaniro ugaragara mubakoresha mudasobwa, kandi irashobora kandi gukoreshwa nkinzibacyuho kugirango habeho kuva kera, hagati kandi hafi yicyerekezo kinini-cyibanze mugihe kizaza.
03Guhitamo ibirahuri bitera imbere
Ibisabwa
Irinde guhitamo amakadiri hamwe na nes nini cyane kuko agace keza ka frames ni nto.
Ibisabwa
Nibyiza kudahitamo amasahani na tr frame idafite amazuru. Ibi ni ukubera ko intera iri hafi yijisho ryaka muri rusange muri rusange ari nto cyane (igomba kubikwa hafi 12Mi), ijisho rimwe ridashobora kugera kumwanya wa hafi-ukoresha ubusanzwe, kandi biragoye guhindura impinga Inguni y'ibirahure.
Ingano y'ibisabwa
Uburebure bwuzuye bujyanye numwanya wabanyeshuri bigomba kubahiriza ibisabwa byagenwe nibicuruzwa, muri rusange biruta cyangwa bingana nibisabwa na 16mm + uburebure bwa 16mm +. Niba haribisabwa bidasanzwe, ugomba kwerekeza kubisabwa kugirango uhitemo ingano ikwiye.
Ibisabwa
Amakadiri hamwe na Strable nziza igomba gutoranywa kugirango wirinde guhindura ibirahuri bikunze kwigira ibisabwa. Ibirahure birashobora kubikwa ku nguni ya dogere 10 kugeza kuri 15. Isura igoramye yikadiri igomba guhuza nuburyo bwo mumaso yambaye. Uburebure, Radian no gukomera kwindorerwamo birakwiriye kwambara bisanzwe.
