Imibare iri ku kirahure cyawe cyerekeranye nimiterere y'amaso yawe n'imbaraga z'icyerekezo cyawe. Barashobora kugufasha kumenya niba ufite kutareba kure, kureba kure cyangwa astigmatism - no kurwego ki.
Niba uzi icyo ugomba gushakisha, urashobora kumvikanisha imibare nincamake ku mbonerahamwe yawe.
OD na OS: Imwe kuri buri jisho
Abaganga b'amaso bakoresha amagambo ahinnye “OD” na “OS” kugirango berekane amaso yawe y'iburyo n'ibumoso.
● OD nijisho ryawe ry'iburyo. OD ni ngufi kuri oculus dexter, interuro y'Ikilatini ngo "ijisho ry'iburyo."
● OS nijisho ryibumoso. OS ni ngufi kuri oculus sinister, Ikilatini kuri "ijisho ry'ibumoso."
Icyerekezo cyawe cyerekanwe gishobora kandi kugira inkingi yanditseho "OU." Iyi ni impfunyapfunyo yaoculus uterque, bisobanura "amaso yombi" mu kilatini. Aya magambo ahinnye arasanzwe kubisobanuro byikirahure, guhuza imiyoboro n'imiti y'amaso, ariko abaganga n'amavuriro bamwe bahisemo kuvugurura imiti yabo bakoreshejeRE (ijisho ry'iburyo)naLE (ijisho ry'ibumoso)mu mwanya wa OD na OS.
Umwanya (SPH)
Umwanya werekana ingano ya lens power yagenewe gukosora kure cyangwa kureba kure. Imbaraga za Lens zapimwe muri diopters (D).
● Niba umubare uri munsi yuyu mutwe uzanye ikimenyetso cyo gukuramo (-),uri kure.
● Niba umubare uri munsi yuyu mutwe ufite ikimenyetso cyongeyeho (+),ureba kure.
Cylinder (CYL)
Cylinder yerekana ingano ya lens power ikeneweastigmatism. Burigihe bukurikiza imbaraga zumurongo ku kirahure.
Umubare uri mu nkingi ya silinderi urashobora kugira ikimenyetso cyo gukuramo (cyo gukosora astigmatisme ireba kure) cyangwa ikimenyetso cyongeweho (kuri astigmatism ya kure).
Niba ntakintu kigaragara muriyi nkingi, ntushobora kuba ufite astigmatisme, cyangwa urwego rwa astigmatism ni ruto kuburyo bidakenewe gukosorwa.
Axis
Axis isobanura lens meridian idafite ingufu za silinderi kurigukosora astigmatism.
Niba indorerwamo y'amaso irimo imbaraga za silinderi, igomba no gushiramo agaciro ka axis, ikurikira imbaraga za silinderi.
Umurongo usobanurwa numubare kuva 1 kugeza 180.
● Umubare 90 uhuye na vertical meridian yijisho.
● Umubare 180 uhuye na horizontal meridian yijisho.
Ongeraho
“Ongeraho” niwongeyeho imbaraga zo gukuzaByakoreshejwe mugice cyo hepfo yinzira nyinshi kugirango ukosore presbyopiya - kurebera karemano bibaho hamwe nimyaka.
Umubare ugaragara muri iki gice cyandikirwa ni imbaraga "wongeyeho", nubwo utabona ikimenyetso cyongeyeho. Mubisanzwe, bizaba kuva kuri +0,75 kugeza kuri +3.00 D kandi bizaba imbaraga zimwe kumaso yombi.
Prism
Nububasha bwimbaraga zidasanzwe, zapimwe muri prism diopters ("pd" cyangwa inyabutatu iyo yanditse kubuntu), byateganijwe kwishyura indishyiguhuza amasoibibazo.
Gusa ijanisha ritoyi ryamaso yindorerwamo harimo gupima prism.
Iyo ihari, ingano ya prism yerekanwa mubice byicyongereza cyangwa ibice byicyongereza (0.5 cyangwa ½, urugero), naho icyerekezo cya prism cyerekanwa no kwerekana aho ugereranije n "" ishingiro "(impande ndende).
Amagambo ane ahinnye akoreshwa muburyo bwa prism: BU = shingiro hejuru; BD = shingiro hasi; BI = shingiro muri (werekeza ku zuru ry'uwambaye); BO = shingiro hanze (yerekeza kumatwi yuwambaye).
