Lens ukeneyeibirahuri byaweBizaterwa nikirahure cyawe.Mbere yo kugura ibirahuri bishya, tegura ikizamini cyamaso hamwe na muganga wamaso.Bazagena ubwoko bw'icyerekezo cyo gukosora ukeneye.
Icyerekezo kimwe
Indorerezi imwe nimwe ihendutse kandi isanzwe yubwoko bwamaso.Bafite umurima munini w'icyerekezo kuko bakosora icyerekezo gusa intera imwe (haba kure cyangwa hafi).Ibi bibatandukanya ninzira nyinshi zasobanuwe hepfo.
Muganga wawe arashobora kuguha icyerekezo kimwe niba ufite kimwe muri ibi bikurikira:
Kureba kure
Kureba kure
Astigmatism
Bifocals
Lens ya Bifocal ni nyinshi, bivuze ko ifite "imbaraga" ebyiri zitandukanye muri zo.Ibi bice bitandukanye bya lens bikosora icyerekezo cyerekezo kandi hafi yicyerekezo.
Indwara ya Bifocal yandikiwe abantu bafite ibibazo byinshi byo kureba.
Trifocals
Lens ya Trifocal isa na bifocals.Ariko bafite imbaraga zinyongera zo gukosora icyerekezo cyo hagati.Kurugero, igice giciriritse gishobora gukoreshwa kugirango urebe ecran ya mudasobwa.
Inenge nyamukuru ya bifocals na trifocals nuko bafite umurongo utandukanye hagati ya buri gice cyerekezo.Ibi bituma ibice bya lens bitanga icyerekezo gitandukanye cyane.Abantu benshi bamenyereye kandi ntibafite ikibazo.Ariko iyi nenge yatumye habaho iterambere ryinshi ryiterambere, nkiterambere.
Iterambere
Iterambere ryiterambere nubundi bwoko bwinzira nyinshi.Bakorera umuntu wese ukeneye bifocals cyangwa trifocals.Iterambere ryiterambere ritanga ubugororangingo bumwe hafi, hagati, no kureba kure.Ibyo babikora nta murongo uri hagati ya buri gice.
Abantu benshi bakunda utwo tuntu twinshi kuko inzibacyuho hagati yimirima yicyerekezo yoroshye.
