Muri sosiyete ya none, umwanda uhumanya ikirere uragenda urushaho gukomera, urwego rwa ozone rwangiritse gato, kandi ibirahure byerekanwa nimirasire yizuba ultraviolet.Impapuro zifotora ni microscopique ingano ya silver halide na oxyde y'umuringa mumurongo urimo ibintu bihindura ibara.Iyo urumuri rwumucyo ukomeye, igice cya feza cyangirika muri feza na bromine, kandi ingano ntoya ya feza yangirika ituma lens igaragara nkumukara wijimye;iyo urumuri rwijimye, ifeza na halide bigarura ifeza igice cya catalizike ya oxyde y'umuringa., bityo ibara rya lens ryongeye kuba ryoroshye.
Icya kabiri, guhindura ibara rya firime ihindura ibara
1. Iyo izuba rirenze: mugitondo, ibicu byo mu kirere biroroshye, imirasire ya ultraviolet ntifunze, kandi byinshi bigera ku butaka, bityo ubujyakuzimu bwihinduranya amabara mugitondo nabwo bwimbitse.Nimugoroba, imirasire ya ultraviolet iba ifite intege nke ugereranije, kubera ko izuba riri kure y’ubutaka nimugoroba, kandi imirasire ya ultraviolet ihagarikwa no kwegeranya ibicu ku manywa;ubujyakuzimu bw'amabara rero ni buke muri iki gihe.
2. Iyo ari ibicu: imirasire ya ultraviolet rimwe na rimwe iba idakomeye kandi irashobora kugera kubutaka, bityo lens ihindura ibara irashobora guhindura ibara.Hafi ya nta bara kandi rifite ibara ryimbere mu nzu, lens ihindura amabara irashobora gutanga ibirahuri bibereye kurinda UV no kurinda urumuri ahantu hose, guhindura ibara ryinzira mugihe ukurikije urumuri, kandi bigatanga uburinzi bwubuzima kumaso umwanya uwariwo wose, ahantu hose mugihe urinda icyerekezo.
3. Isano iri hagati yinzira ihindura ibara nubushyuhe: Mubihe bimwe, uko ubushyuhe bwiyongera, ibara ryinzira zihindura amabara bizagenda byoroha buhoro buhoro uko ubushyuhe bwiyongera;muburyo bunyuranye, iyo ubushyuhe bugabanutse, ibara rihindura ibara rizagenda gahoro.Buhoro buhoro.Niyo mpamvu ihinduka urumuri mu cyi n'umwijima mu gihe cy'itumba.
4. Umuvuduko wamabara ahinduka, ubujyakuzimu nabwo bujyanye nubunini bwinzira
