Nhamba dziri pagwaro regirazi rako remaziso dzinoenderana nechimiro chemaziso ako uye kusimba kwekuona kwako. Vanogona kukubatsira kuona kana uine kuona pedyo, kuona kure kana astigmatism - uye kusvika papi.
Kana iwe uchiziva zvekutsvaga, unogona kuita pfungwa dzenhamba uye zvipfupiso pane yako yekuraira chati.
OD vs. OS: Imwe yeziso rega rega
Vanachiremba vemaziso vanoshandisa zvipfupiso "OD" uye "OS" kuratidza maziso ako ekurudyi nekuruboshwe.
● OD iziso rako rorudyi. OD ipfupi kune oculus dexter, mutsara wechiLatin wekuti "ziso rekurudyi."
● OS ziso rako rekuruboshwe. OS ipfupi kune oculus sinister, chiLatin che "ziso rekuruboshwe."
Chiratidzo chako chechiratidzo chinogonawo kuva nechikamu chakanyorwa kuti "OU." Uku ndiko kudimburirwa kweoculus uterque, zvinoreva kuti "maziso ose" muchiLatin. Aya mazwi akapfupikiswa akajairika pane zvinyorwa zvemagirazi, macontact lenses nemishonga yemaziso, asi vamwe vanachiremba nemakiriniki vakasarudza kugadzirisa mishonga yemaziso nekushandisa.RE (ziso rekurudyi)uyeLE (ziso rekuruboshwe)panzvimbo yeOD uye OS.
Sphere (SPH)
Sphere inoratidza huwandu hwesimba re lens rakatemerwa kugadzirisa kuona pedyo kana kuona kure. Simba reLens rinoyerwa muma diopters (D).
● Kana nhamba iri pasi pemusoro uyu ikauya nechiratidzo chekubvisa (-),unoona zviri pedyo.
● Kana nhamba iri pasi pemusoro uyu iine chiratidzo chekuwedzera (+),unoona zviri kure.
Silinda (CYL)
Cylinder inoratidza huwandu hwesimba re lens rinodiwaastigmatism. Iyo inogara ichitevera sphere simba pane yegirazi rekunyorera.
Nhamba iri muhumburumbira mukoramu inogona kunge iine minus sign (yekugadzirisa ari pedyo astigmatism) kana kuti plus sign (yekuona kure astigmatism).
Kana pasina chinoonekwa mukoramu iyi, iwe hauna astigmatism, kana dhigirii rako reastigmatism idiki zvekuti haridi kugadziriswa.
Axis
Axis inotsanangura lens meridian iyo isina silinda simba rekuitaastigmatism yakarurama.
Kana girazi remaziso rinosanganisira simba rehumburumbira, inodawo kusanganisira kukosha kweaxis, iyo inotevera simba rehumburumbira.
Axis inotsanangurwa nenhamba kubva pa1 kusvika ku180.
● Nhamba ye90 inoenderana nemeridian yakatwasuka yeziso.
● Nhamba ye180 inoenderana nehorizontal meridian yeziso.
Wedzera
"Wedzera" ndiyeakawedzera simba rokukudzainoiswa pasi pechikamu chepasi chemultifocal lenzi kugadzirisa presbyopia - kuona kwechisikigo kunoitika nezera.
Nhamba irikuonekwa muchikamu chino chemishonga inogara iri "plus" simba, kunyangwe iwe usingaone chiratidzo chekuwedzera. Kazhinji, ichabva ku +0.75 kusvika +3.00 D uye ichava simba rimwechete remaziso ose.
Prism
Uhwu ndihwo huwandu hwesimba reprismatic, rinoyerwa mumaprism diopters ("pd" kana katatu kana rakanyorwa mahara), rinotemerwa kuripakurongeka kwezisomatambudziko.
Chikamu chidiki chete chezvinyorwa zvegirazi remaziso chinosanganisira kuyerwa kweprism.
Kana iripo, huwandu hweprism hunoratidzwa mune metric kana chidimbu cheChirungu mayunitsi ( 0.5 kana ½, semuenzaniso), uye kutungamira kweprism kunoratidzwa nekucherechedza chinzvimbo che "base" yayo (yakakora mupendero).
Zvidimburiso zvina zvinoshandiswa kunzira yeprism: BU = base up; BD = chigadziko pasi; BI = chigadziko mukati (akananga kumhino yeanopfeka); BO = base out (kunzeve yomuchengeti).
Kana iwe uine zvimwe zvaunofarira kana uchida rumwe ruzivo rwehunyanzvi pane optical lenses, ndapota pinda mune yedu peji kuburikidzahttps://www.universeoptical.com/stock-lens/kuti uwane rumwe rubatsiro.
