1 、Icyerekezo kimwe:
Icyerekezo kimweikubiyemo intera, gusoma na Plano.
Gusoma ibirahuri birashobora gukoreshwa mukureba terefone y'intoki, mudasobwa, kwandika n'ibindi.Ibirahurizikoreshwa mukubona ibintu byegeranye byumwihariko, bishobora gutuma amacumbi yijisho aruhuka kandi atari umunaniro cyane.
Ibirahure bya kure birashobora gukoreshwa mugutwara, kuzamuka, kwiruka hamwe nibikorwa bimwe byo hanze.IbirahuriByakoreshejwe Kuri Kubona Intera Yihariye.
Hano hari ibirahuri byo gutandukanya intera no gusoma.
Ibirahuri bya Plano ni ibirahuri bitanditse, bishobora gukoreshwa mu kurinda umuyaga n'umucanga gusa, cyangwa kugaragara neza.
2 、Bifocal
Igishushanyo mbonera cyashizeho uburebure bwo hejuru bwibanze bwa lens kugirango bushobore kureba ibintu birenga metero 3, mugihe igice cyo hepfo cyashizweho kugirango turebe hafi yimiterere yibyabaye.Igishushanyo gifasha uwambaye ibirahure kureba intera / hafi yibintu bitandukanye.Ntabwo ari ngombwa gukuramo ibirahuri, bitanga ubworoherane kubantu ba presbyopiya.
3 ives Iterambere
Lens igenda itera imbereni ubwoko bwa lens bushobora kubona kure na hafi.Hano haribice bibiri byingenzi bimurika mugushushanya gutera imbere kuri chip.Uruhande rwo hepfo rwizuru ni agace kegereye;Gukomeza amashusho agaragara bigerwaho binyuze mukarere kinzibacyuho hagati yakarere kareba kure nakarere kegereye.Usibye gukenera uwambaye gukuramo ibirahuri mugihe witegereje kure / hafi yikintu, kugenda kwijisho hagati yuburebure bwo hejuru no hepfo byerekezo nabyo biratera imbere.Gusa ibibi ni uko hari impamyabumenyi zitandukanye zerekana itandukaniro ryinshi ryamashusho kumpande zombi zigenda zitera imbere, bizatera imyumvire yo kwiyongera mubyerekezo bya periferi.
Iterambere ritanga inzibacyuho yoroheje kuva kure unyuze hagati kugeza hafi, hamwe na byose biri hagati yo gukosora harimo.Urashobora kureba hejuru kugirango ubone ikintu cyose kiri kure, reba imbere kugirango urebe mudasobwa yawe muri zone yo hagati, hanyuma utere amaso hasi kugirango usome kandi ukore akazi keza neza muri zone yegeranye.Nukuvuga ko, lens igenda itera imbere yegereye uburyo iyerekwa risanzwe ari uko ushobora kubona mubirahuri byandikirwa.
