Nhamba dziri papepa regirazi rako remaziso dzine chekuita nechimiro chemaziso ako uye simba rekuona kwako. Dzinogona kukubatsira kuona kana uine kuona zviri pedyo, kuona zviri kure kana kuti astigmatism — uye kusvika papi.
Kana uchiziva zvekutsvaga, unogona kunzwisisa nhamba nezvidimbu zviri pachati yako yemishonga.
OD vs. OS: Rimwe paziso rega rega
Vanachiremba vemaziso vanoshandisa zvipfupiso zve "OD" uye "OS" kuratidza maziso ako ekurudyi nekuruboshwe.
● OD iziso rako rekurudyi. OD ipfupiso ye oculus dexter, izwi rechiLatin rinoreva "ziso rekurudyi."
● OS iziso rako reruboshwe. OS ishoko rakapfupikiswa rekuti oculus sinister, muchiLatin rinoreva "ziso reruboshwe."
Chiremba chako chekuona chinogonawo kunge chine koramu yakanyorwa kuti "OU." Ichi ndicho chipfupiso cheoculus uterque, zvinoreva kuti "maziso ese" muchiLatin. Aya mazwi akapfupikiswa anowanzo shandiswa pakunyora magirazi, magirazi ekuona uye mishonga yemaziso, asi vamwe vanachiremba nemakiriniki vakasarudza kugadzirisa mishonga yavo yemaziso nekushandisaRE (ziso rekurudyi)uyeLE (ziso rekuruboshwe)pachinzvimbo cheOD neOS.
Dunhu (SPH)
Simba remalenzi rinoratidza huwandu hwesimba remalenzi rakanyorerwa kugadzirisa kuona zviri pedyo kana kuona zviri kure. Simba remalenzi rinoyerwa mu diopters (D).
● Kana nhamba iri pasi pemusoro uyu iine chiratidzo chekusiya (–),uri kuona zviri pedyo.
● Kana nhamba iri pasi pemusoro uyu iine chiratidzo chekuwedzera (+),unoona zviri kure.
Sirinda (CYL)
Sirinda inoratidza huwandu hwesimba remalenzi rinodiwaastigmatismNguva dzose inotevedzera simba rebhora riri pagirazi remaziso.
Nhamba iri mukoramu yesirinji inogona kunge iine chiratidzo chekusiya (chekugadzirisa astigmatism inoonekwa nearsenic) kana chiratidzo chekuwedzera (che astigmatism inoonekwa nearsenic).
Kana pasina chinoonekwa muchikamu chino, unenge usina astigmatism, kana kuti mwero weastigmatism wako mudiki zvekuti haufanirwe kugadziriswa.
Akisi
Axis inotsanangura lenzi inonzi meridian isina simba re cylinder rekushandisaastigmatism chaiyo.
Kana mushonga wegirazi remaziso uine simba resilinda, unofanirawo kusanganisira axis value, iyo inotevera simba resilinda.
Akisi inotsanangurwa nenhamba kubva pa1 kusvika 180.
● Nhamba 90 inoenderana ne meridian yakatwasuka yeziso.
● Nhamba 180 inoenderana ne meridian yakatambanuka yeziso.
Wedzera
"Wedzera" ndiyoyakawedzera simba rekuwedzeraInoiswa pasi pemalenzi e multifocal kugadzirisa presbyopia — kuona zviri kure kunoitika nekukura.
Nhamba iri muchikamu chino chemushonga inogara iri simba re "plus", kunyangwe usingaone chiratidzo che "plus". Kazhinji, ichave kubva pa +0.75 kusvika +3.00 D uye ichave simba rakafanana remaziso ese ari maviri.
Prism
Uhu ndihwo huwandu hwesimba re prismatic, rinoyerwa mu prism diopters ("pd" kana triangle kana yakanyorwa nemaoko), rinorayirwa kubhadharakurongeka kwemazisomatambudziko.
Chikamu chidiki chete chemishonga yegirazi remaziso chinosanganisira kuyerwa kweprism.
Kana iripo, huwandu hweprism hunoratidzwa muzvikamu zvechirungu zvemetric kana fractional (semuenzaniso 0.5 kana ½), uye divi reprism rinoratidzwa nekutarisa nzvimbo ye "base" yayo (mupendero wakakora).
Mapfupiso mana anoshandiswa pakusarudza nzira yeprism: BU = base up; BD = base down; BI = base in (kune mhino yemupfeki); BO = base out (kune nzeve yemupfeki).
