Nigute ushobora guhitamo no kwambara amadarubindi?

Indorerwamo z'izuba nazo zitwa izuba.Mu mpeshyi no mu bibaya, abantu bakunze kwambara amadarubindi yizuba kugirango birinde guterwa numucyo mwinshi no guhagarika kwangirika kwimirasire ya ultraviolet kumaso.Hamwe no kuzamura imibereho, abantu bakunda amaso yabo cyane.Ku zuba, imirasire ya ultraviolet yangiza amaso.Ibiri mu mirasire ya ultraviolet mu mirasire y'izuba bigera ku isi bingana na 7%.Cornea na lens byijisho ryumuntu ni tissue ocular ishobora kwangirika kwa UV.Indwara ya Cataract nindwara zamaso zifitanye isano cyane nimirasire ya ultraviolet.Indwara z'amaso nka keratite y'izuba, gukomeretsa kwa corneal endothelia, amabara y'amaso, hamwe na retinite byose bifitanye isano n'imirasire ya ultraviolet.Indorerwamo zizuba zujuje ibyangombwa zifite umurimo wo guhagarika ultraviolet nimirasire yimirasire.Kubwibyo, twavuga ko kwambara amadarubindi yizuba mugihe cyizuba nimwe muburyo bwiza bwo kurinda amaso imirasire ya ultraviolet.

Indorerwamo zizuba zigabanyijemo ibyiciro bibiri: ibara ryumucyo n-ibara ryijimye, kandi rigizwe namabara atandukanye.Kugira ngo hamenyekane ubwiza bw'amadarubindi, icyibandwaho kigomba kwibanda ku bipimo byinshi bya tekiniki nk'imbaraga za vertex n'imbaraga za prism, ibiranga ibipimo byoherejwe, ubwiza bw'ubuso hamwe n'inenge zo mu mutima, guterana neza hamwe n'ibisabwa.

Indorerwamo nziza yizuba irashobora kugicucu no gushushanya hanze.Ariko ku isoko, ibintu nyirizina ntabwo ari byiza.Abacuruzi bamwe bibagirwa inyungu, bagakoresha inyungu zabaguzi badasobanukiwe nubwiza bwamadarubindi yizuba, kandi bagakoresha ibirahuri byujuje ubuziranenge, bidahenze byikirahure cyangwa ibindi bikoresho byo hasi kugirango bakore ibirahure.Ibi bikoresho bifite uburinganire buke, birimo imirongo, ibibyimba nibindi byanduye, ntibishobora guhagarika imirasire ya ultraviolet, kandi ntabwo byujuje ibisabwa byumubiri wijisho ryumuntu.Ikirenzeho, gukoresha amabati ya plastike yo hasi hamwe no kohereza urumuri ruto cyane ariko rwohereza ultraviolet yohereza amadarubindi yizuba bizatera abaguzi nabi.

Nigute ushobora guhitamo no kwambara amadarubindi?Impuguke ziributsa abaguzi kutita gusa ku buryo bw'amadarubindi y'izuba, ahubwo no ku bwiza bwabo.Indorerwamo zizuba zujuje ibyangombwa, ihererekanyabubasha ry’imirasire miremire ya ultraviolet ifite uburebure buri hagati ya 315nm na 380nm ntigomba kurenga 10%, kandi ihererekanyabubasha ry’imishwarara ya ultraviolet ifite uburebure buri hagati ya 280nm na 315nm igomba kuba zeru.Kwambara amadarubindi y'izuba birashobora kurinda cornea, lens na retina y'amaso kwangirika kwa UV.Indorerwamo zizuba zihenze ntizishobora gusa gushungura imirasire ya ultraviolet, ariko kandi zifunga urumuri rugaragara, bigatuma imishwarara ya ultraviolet igaragara cyane.Nibyiza kutambara amadarubindi yizuba.

Indorerwamo zizuba ni urwego rwindorerwamo.Ukurikije ibipimo byigihugu, indorerwamo zizuba zemerewe gusa kugira diopter ya plus cyangwa gukuramo dogere 8, kandi hejuru yaya makosa ni ibicuruzwa bitujuje ubuziranenge.Nk’uko ubushakashatsi bwakozwe bwerekana ko amadarubindi y’izuba ku isoko yakozwe n’abashakashatsi, hafi 30% y’amadarubindi y’izuba afite diopter irenze kwihanganira, ndetse hari n’uburebure bwa dogere 20.Abahanga bagaragaza ko abaguzi bafite icyerekezo gisanzwe bambara amadarubindi yizuba, kimwe no kwambara ibirahuri bya myopiya cyangwa hyperopiya.Nyuma yizuba, abaguzi "bazahugurwa" kubarwayi ba myopiya cyangwa hyperopiya hamwe nizuba rito.Mugihe uhuye nibimenyetso nko kuzunguruka, isesemi, no kurabagirana nyuma yo kwambara amadarubindi, ugomba guhita wambara.
