Hariho ibyiciro 4 byingenzi byerekana icyerekezo-Emmetropia, Myomero, Hyperopiya, na Astigmatism.
Emmetropia ni iyerekwa ryiza. Ijisho rimaze gutunganya neza kuri retina kandi ntisaba gukosora ibirahuri.
Myopiya irazwi cyane nko kurekurwa. Bibaho iyo ijisho rirerire cyane, bikaviramo kwibanda imbere ya retina.
Kugirango akosore kuri Myopia, umuganga w'amaso wawe azakwandikisha lens lens (-x.xx). Iyi mito ya monus isunika aho yibanda inyuma kugirango ihuza neza kuri retina.
Myopia nuburyo bukunze kugaragara bwo gukosora amakosa muri iki gihe. Mubyukuri, mubyukuri biratekereza ko icyorezo cyisi yose, nkuko abaturage benshi kandi benshi bafatwa nkiki kibazo.
Aba bantu barashobora kubona hafi hafi, ariko ibintu kure bisa biratangaje.
Mu bana, urashobora kubona umwana ufite ikibazo cyo gusoma ikibaho kwishuri, ufashe ibikoresho byo gusoma (terefone ngendanwa, ibitabo byinjira mu maso habo, etc.
Ku rundi ruhande, Hyperopia, iboneka iyo umuntu ashobora kubona neza kure, ariko ashobora kugira ikibazo cyo kubona ibintu hafi.
Bimwe mubibazo bikomeye hamwe na hyperopes mubyukuri ntabwo aribyo badashobora kubona, ahubwo ko babona umutwe nyuma yo gusoma cyangwa gukora akazi ka mudasobwa, cyangwa ngo amaso yabo ake yumva ananiwe cyangwa ananiwe.
Hyperopia ibaho iyo ijisho ari rigufi cyane. Kubwibyo, urumuri rwibanze inyuma ya retina.
Hamwe nicyerekezo gisanzwe, ishusho yibanze cyane hejuru ya retina. Mu kurema (Hyperopia), CORNESA yawe ntabwo ihindura urumuri neza, bityo ingingo yibanze igwa inyuma ya retina. Ibi bituma ibintu byegeranye bigaragara.
Kugira ngo ukosorwe hyperopia, abaganga b'amaso batanga Plus (+ x.xx) kugirango bazane ingingo yo kwibanda ku butaka neza kuri retina.
Astigmatism ni izindi ngingo zose. Astigmatism ibaho iyo hejuru yimbere yijisho (cornea) ntabwo ari uruziga rwose.
Tekereza kuri cornea isanzwe isa na basketball yaciwemo kabiri. Nibyiza neza kandi bingana mubyerekezo byose.
Cornea ya Astigmatic isa nkigitoki cyatetse cyaciwemo kabiri. Umurimpimoni umwe ni muremure kuruta undi.
Kugira abarisiya babiri batandukanye byijisho bivamo ingingo ebyiri zitandukanye. Kubwibyo, lens yikirahure ikeneye gukorwa kugirango akosore Meridian. Iyi nyandiko izaba ifite imibare ibiri. Kurugero-1.00 -0.50 x 180.
Umubare wambere usobanura imbaraga zikenewe kugirango ukosore Meridian imwe mugihe umubare wa kabiri ugaragaza imbaraga zikenewe kugirango ukosore undi Merideni. Umubare wa gatatu (x 180) havuga gusa aho abarimbika bombi babeshya (barashobora kuva kuri 0 kugeza 180).
Amaso ni nk'igicapo cy'intoki - nta bibiri ari kimwe. Turashaka ko ubona ibyiza byawe, bityo rero umusaruro unyuranye nindi misaruro dushobora gukorera hamwe kugirango ubone igisubizo cyuzuye cyo kuzuza ibyo ukeneye.
Isanzure irashobora gutanga lens nziza kugirango ukosore ibibazo byavuzwe haruguru. Pls yibanda kubicuruzwa byacu:www.uniurseoptical.com/ibicuruzwa/
