Nhamba dziri pane yako yegonzo mishonga yeziso zvine chimiro chemaziso ako uye simba rewiser. Vanogona kukubatsira iwe kufunga kuti unazvo nearsedness, inofamba-farira kana astigmatism - uye kusvika padanho ripi.
Kana iwe uchiziva kuti chii chekutsvaga, iwe unogona kuita pfungwa yehuwandu uye zvipfupiso pane yako yekunyoresa chati.
Od vs. OS: imwe yeziso rimwe nerimwe
Vanachiremba veZiso vanoshandisa zvidimbu "OD" uye "OS" kuratidza maziso ako kurudyi uye kuruboshwe.
● Od iziso rako rorudyi. Od ipfupi kune oculus dexter, mutsara wechiLatin we "ziso rorudyi."
● OS iziso rako reruboshwe. OS ipfupi yeOculus Sinister, Latin ye "ziso reruboshwe."
Dziviriro yako yekuona inogona zvakare kunge ine ikholamu yakanyorwa "Ou." Uku ndiko kupfupika kweOculus Urever, zvinoreva kuti "maziso maviri" muchiLatin. Iyi mazwi akapfurwa anozivikanwa pane mishonga yegirazi, Bata Lenses uye mishonga yemaziso, asi vamwe vanachiremba nemakiriniki vakasarudza kusimudzira ziso ravo mishonga yekuzvidza nekushandisaRe (ziso rorudyi)uyeLe (ziso rekuruboshwe)panzvimbo yeOd uye OS.
SPHENCHE (SPH)
SPHENCHE inoratidza huwandu hwesimba re lens rakarairwa kururamisa pachena kana kutarisisa. Lens simba rinoyerwa mu diopters (d).
● Kana nhamba iri pasi pemusoro uyu inouya neinini chiratidzo (-),Iwe uri panoratirwa.
● Kana iyo nhamba iri pasi peiyi musoro ine chiratidzo chekuwedzera (+),Iwe unofarira.
Cylinder (cyl)
Cylinder inoratidza huwandu hwesimba re lens rinodiwaastigmatism. Inogara ichitevera iyo SPHENT SIMBA PAMUSORO PENYAYA YEMAHARA.
Nhamba iri muCylinda Chikara inogona kuve neinini chiratidzo (chekururamisa kwesarts
Kana pasina chichaonekwa mukarowa iri, iwe hauna asviligmatism, kana yako degree reasmigmatism iri diki zvekuti hazvidi kurangwa.
Axis
Axis inotsanangura lens meridian iyo isina simba recylinder kunekururamisa astigmatism.
Kana mishonga yeziso yemaziso inosanganisira Silust Simba, zvinodawo kusanganisira kukosha kweAxis, inotevera simba reCylinder.
Iyo axis inotsanangurwa neye nhamba kubva 1 kusvika 180.
● Nhamba 90 inoenderana nemhando yemutungamiriri weziso.
● Nhamba 180 inoenderana nemamita akatwasuka weziso.
Wedzera
"Wedzera" ndizvoYakawedzera simba rinokudzaShandiswa kune chikamu chepasi cheltificeal lens kuti kururamisa Presbypia - iyo yakasarudzika mamiriro ezvinhu anoitika nezera.
Nhamba yacho inoonekwa muchikamu ichi yemucherechedzo inogara iri "kuwedzera" simba, kunyangwe iwe usingaone chiratidzo chekuwedzera. Kazhinji, ichangobva kubva paI +0.75 kusvika +3.00 d uye ichave isimba rimwe chete remaziso ese ari maviri.
Prism
Iyi ndiyo huwandu hwesimba rezvemasimba, rakayerwa muPrism DiosterZiso Rinogonamatambudziko.
Chete chikamu chidiki chete cheyegirinhi mishonga yeziso inosanganisira chiyero chePrism.
Pano parizvino, huwandu hweprism hunoratidzwa mumametric kana chidimbu chechirungu (0.5 kana ½, semuenzaniso), uye kutungamira kwechiitiko kunoratidzwa nekucherekedza chinzvimbo che "base"
Zvipfupiso zvina zvinoshandiswa kune prism nhungamiro: bu = chikamu kumusoro; BD = BATE pasi; Bi = Base mu (akananga mhino yemupopotera); Bo = chigadziko kunze (akananga nzeve yemutengesi).
