Imibare kuri eregriction yawe ya ereglass ijyanye nuburyo amaso yawe nimbaraga zawe. Barashobora kugufasha kumenya niba ufite Kubura neza, Kureba cyangwa Astigmatisma - ndetse nimpamyabumenyi.
Niba uzi icyo ushakisha, urashobora kumva imibare no guhira amagambo ku mbonerahamwe yandikiwe.
Od na os: imwe kuri buri jisho
Abaganga b'ijisho bakoresha amagambo ahinnye "OD" na "OS" kugirango bagaragaze amaso yawe iburyo.
● od nijisho ryawe. OD ni ngufi kuri deculus dexter, interuro y'Ikilatini ya "Ijisho ry'iburyo."
● OS Ijisho ryawe ryibumoso. OS ni ngufi kuri oculus sinister, ikilatini kuri "ijisho ryibumoso."
Icyerekezo cyawe gishobora kandi kugira inkingi yanditseho "OU." Iri ni amagambo ahinnyeOculus Uterque, bivuze ngo "amaso yombi" mu kilatini. Aya magambo ahinnye asanzwe afite intego zo kubirahure, Twandikire Lens nimiti yijisho, ariko abaganga hamwe namavuriro bahisemo kuvugurura ibyo bakoresheje ijisho bakoreshejeRe (ijisho ryiburyo)naLe (ijisho ryibumoso)aho kuba od na os.
Urwego (sph)
Sphere yerekana umubare wimbaraga za lens zateganijwe neza kureshya neza cyangwa kurega. Lens imbaraga zipimwa muri diopters (d).
● Niba umubare uri munsi yuyu mutwe uzana ikimenyetso cyo gukuramo (-),Urasakuza.
● Niba umubare uri munsi yumutwe ufite ikimenyetso (+),Urareba.
Silinderi (cyl)
Silinder yerekana umubare wimbaraga za lens zikeneweAstigmatism. Buri gihe gikurikira imbaraga zumutekano kuri preglass.
Umubare muri silinderi urashobora kugira ikimenyetso cyo gukuramo (gukosora astigmatism nziza) cyangwa ikimenyetso cyongeyeho (kuri Astigmatism ya kure).
Niba ntakintu kigaragara muriyi nkingi, ntushobora kuba ufite nka atigmatism, cyangwa urwego rwa ASTICMATIM ni muto cyane kuburyo bidakenewe gukosorwa.
Axis
Axis isobanura lens meridian itarimo silinderi imbaraga kurigukosora astigmatism.
Niba uwanditse amaso arimo ububasha bwa silinderi, igomba kandi gushyiramo agaciro ka axis, ikurikira imbaraga za silinderi.
Axis isobanurwa numubare kuva 1 kugeza 180.
● Umubare wa 90 uhuye na Merticy Meridian yijisho.
● Umubare 180 uhuye na Merigamian Merideni yijisho.
Ongeraho
"Ongeraho" niwongeyeho imbaragaByakoreshejwe igice cyo hepfo yinzira nyabuto nyinshi kugirango ukosore Presbyopia - ibiciro bisanzwe bibaho hamwe nimyaka.
Umubare ugaragara muri iki gice cyanditse buri gihe ari "wongeyeho", nubwo utabonye ikimenyetso. Mubisanzwe, bizatera +0.75 kugeza +3.00 d kandi bizaba imbaraga kumaso yombi.
Prism
Nuburyo bw'imbaraga za prismatique, bipimirwa muri prism diopters ("pd" cyangwa inyabutatu mugihe yanditseho Freehand), yagenewe kwishyura indishyiGuhuza amasoibibazo.
Gusa ijanisha rito ryibisobanuro bya eyeglass harimo gupima prism.
Iyo uhari, ingano ya prism yerekanwa mubice bya metero cyangwa buri munsi (0.5 cyangwa ½, kurugero), hamwe nubuyobozi bwa prism bwerekanwa no kumenya umwanya wacyo "shingiro).
Ibice bine bikoreshwa mu cyerekezo cya prism: Bu = shime; Bd = shingira hasi; Bi = shingiro muri (kuzuru wambaye imyenda); Bo = Shingwa hanze (werekeza kumatwi yambaye imyenda).
