Lens irwanya ubururu ifite igipimo cyo guhagarika hejuru ya 20% ukurikije ibipimo bya ISO birasabwa gukoresha buri munsi ibikoresho byerekana ibyuma bya LED nka tereviziyo, mudasobwa, amakariso na terefone zigendanwa. Lens irwanya ubururu ifite igipimo cyo guhagarika hejuru ya 40% ukurikije igipimo cya ISO irasabwa kwambarwa nabantu bareba ecran amasaha arenga 8 kumunsi. Kuberako ibirahuri birwanya ubururu byungurura igice cyurumuri rwubururu, ishusho izaba umuhondo mugihe ureba ibintu, birasabwa kwambara ibirahuri bibiri byikirahure, ikirahuri kimwe gisanzwe kugirango ukoreshwe burimunsi, hamwe nikirahuri kimwe kirwanya ubururu hamwe nigipimo cyo guhagarika kirenga 40% mugukoresha LED yerekana ibicuruzwa bya mudasobwa nka mudasobwa. Flat (nta mpamyabumenyi) irwanya ubururu ibirahuri byamamaye cyane mubakoresha non-myopic, cyane cyane kwambara ibiro bya mudasobwa, hanyuma buhoro buhoro biba imyambarire.

Intangiriro

2, kwerekana firime: lens hejuru yububiko, binyuze muri firime bizaba byangiza urumuri rwubururu, intego yuburinzi bwa barrière.

3, substrate absorption + firime yerekana: iri koranabuhanga rihuza ibyiza byikoranabuhanga rya mbere ryambere, impande ebyiri, kurinda ingaruka ebyiri. [3]

Ukurikije ihame ryamabara yuzuzanya, ubururu numuhondo ni amabara yuzuzanya. Yaba yakiriwe na lens substrate cyangwa ikagaragazwa na firime ya firime, igice cyurumuri rwubururu kirahagaritswe, bityo ibara ryinyuma ryibirahuri birwanya ubururu bizaba umuhondo. Umubare munini wa bariyeri, niko ibara ryimbere ryibara rya lens rizaba. Iri ni ihame shingiro ryumubiri ryibirahure birwanya ubururu.

Itara ryubururu ryangiza rifite imbaraga nyinshi cyane, rishobora kwinjira mumurongo wa retina, bigatuma ingirabuzimafatizo ya epiteliyale itagaragara ndetse ikanapfa. Urupfu rw'uturemangingo twumva urumuri rushobora gutuma umuntu atabona neza cyangwa akabura burundu, kandi ibyo byangiritse ntibisubirwaho. Itara ry'ubururu rishobora kandi gutera indwara ya macula. Intumbero yijisho ryumuntu ikurura igice cyurumuri rwubururu kandi buhoro buhoro ihinduka ibicu kugirango ikore cataracte. Ibyinshi mu rumuri rwubururu byinjira mumurongo, cyane cyane lens ya kirisiti isobanutse yabana, idashobora kurwanya neza urumuri rwubururu, bikaba bishoboka cyane ko bitera indwara ya macula na cataracte.

Guhagarika itara ry'ubururu igihe kirekire nuburyo bwiza cyane bwo kugabanya ibyangiritse, kandi gukoresha ibirahuri byubururu bifunga ibirahure birashobora gukemura neza iki kibazo.
