Igihe icyi cyegereje, kwambara amadarubindi yerekana amadarubindi byahindutse ibintu.Tugenda mumuhanda, tuzabona abantu bambaye amadarubindi.Nyamara, kubagenzi bafite myopiya nibikenewe bidasanzwe byamaso, bakeneye kwambara ibirahuri bya myopiya hamwe nizuba.Kubwibyo, igisubizo cyoroshye kandi cyizewe nuguhitamo ibirahuri byamabara bihuye nurwego rwawe, kugirango ikibazo gikemuke.
Lens, bizwi kandi nka "linzira zifite ubwenge bworoshye", zikoreshwa cyane mukurinda amaso no kugabanya umunaniro ugaragara mugabanya urumuri rukomeye, imirasire ya UV numucyo wubururu kutinjira mumaso.Ibintu byoroshye urumuri (nka silver halide) byongewe mumurongo kandi bigahura na ultraviolet hamwe numuhengeri mugufi ugaragara, ibara rihinduka umwijima kandi itumanaho rikagabanuka.Ahantu h'imbere cyangwa hijimye, itumanaho ryumucyo rya lens riratera imbere, kandi ibara rirashira kandi umucyo ukagaruka.Photochromism ya lens irikora kandi irashobora guhinduka.Lens ya Photochromic irashobora guhindura itumanaho ryumucyo uhindura ibara ryinzira, kugirango ijisho ryumuntu rishobore guhuza nimpinduka zumucyo wibidukikije.
Lens
Lensreba ikoreshwa ryibintu bimwe na bimwe bisiga amabara mugihe cyo gukora lens kugirango ukore lens igaragara ibara kandi ikurura uburebure bwihariye bwumucyo.Indorerwamo zahinduwe zikoreshwa mubirahuri by'izuba.Ugereranije nubusanzwe busanzwe bwa resin, ifite imbaraga zo kurwanya UV no kurwanya imirasire.
Lens yahinduwe iratera imbere byihuse muriyi minsi.Hariho intera nini y'amabara.Mugihe gikwiye, ugomba gushaka inama za optometriste kugirango uhitemo ibara ryiza.Irakwiriye kubantu bamwe barwaye ibisebe, macula degeneration, na Photophobia y'amaso nyuma yo kubagwa cataracte.Abantu barwaye amaso bakeneye guhitamo lens zijyanye nibara ryamaso.
Ibice byinshini lens yakozwe ishingiye ku ihame rya polarisiyasi yumucyo, ifite umurimo wo kurandura urumuri, bigatuma kureba neza kandi karemano.Barashobora kunoza icyerekezo cyumushoferi no kongera umunezero wo gutwara.
Ingaruka ya polarizing lens ni kuyungurura urumuri, bigatuma umurima wo kureba usobanutse kandi karemano.Bisa nihame ryumwenda utabona, urumuri ruhindurwa kugirango rwinjire mu jisho mu cyerekezo kimwe, mubisanzwe bituma ibiboneka bigaragara byoroshye kandi ntibitangaje.Kongera amabara no gutandukanya, kongera ihumure n'umutekano wo gutwara, guhagarika urumuri rwangiza, kandi nibikoresho byingenzi kubashoferi bamara igihe kirekire hamwe nabakunda gusiganwa ku magare.
