Kuongorora kwemaziso uye girazi remaziso

Kana iwe uchida kuratidzwa kwekuona zvichitevera kuongorora kwemaziso, ophthalmologist wako kana chiremba wezve meso achakuzivisa iwe kana uri pedyo kana kuona kure. Ivo vanogona kutokuudza iwe kuti une astigmatism.

Nechero kuongororwa, iwe unozopihwa mushonga wekugadzirisa maziso. Yako tsamba yekunyora ichave ine akati wandei akapfupikiswa mazwi akadai se:

• OD
• OS
• SPH
• CYL

Unoziva here kuti izvi zvinorevei? Tinotsanangura.

Zvinorevei OD vs. OS?

Nhanho yekutanga yekunzwisisa mushonga kubva kuna chiremba weziso rako kuziva OD uye OS. Izvi zvinongova zvipfupiso zvemazwi echiLatin:

• OD chidimbu che "oculus dexter" chino chiLatin che "ziso rerudyi.”
• OS chidimbu che "oculus sinister" inova chiLatin kune "ziso rekuruboshwe.”

Tsamba yaunonyorwa inogona zvakare kunge iine chikamu cheOU, chinova chidimbu che "oculus uterque," chiLatin che "maziso ese ari maviri."

Kunyange hazvo OS uye OD ari zvipfupiso zvechinyakare zvinoshandiswa muzvinyorwa zvegirazi remaziso, malenzi ekubata, uye mishonga yemaziso, kune vamwe vanachiremba vakavandudza mafomu avo ekunyora nekutsiva OD neRE (ziso rerudyi) uye OS neLE (ziso rekuruboshwe).

Mamwe mapfupikiso pane yako tsamba yegirazi yemaziso

Zvimwe zvipfupiso zvaunogona kuona pane yako girazi gwaro rinonyorwa zvinosanganisira SPH, CYL, Axis, Wedzera, uye Prism.

SPH

SPH ipfupiso ye "bhora" iyo inoratidza simba re lens iro chiremba wako arikunyora kuti agadzirise chiono chako.

Kana iwe uri pedyo-kuona (myopia), nhamba yacho ichava nechiratidzo chekubvisa (-). Kana iwe uri kuona zviri kure (hyperopia), iyo nhamba ichave ine yekuwedzera chiratidzo (+).

CYL

CYL ipfupiso ye "humburumbira" iyo inoratidza iyo lens simba iro chiremba wako arikugadzirira kugadzirisa yako astigmatism. Kana pasina nhamba mukoramu iyi, saka chiremba wako haana kuwana astigmatism kana yako astigmatism haidi kugadziriswa.

Akabatana

Axis inhamba kubva pa1 kusvika pa180. Kana chiremba wako akaisa humburumbira simba, pachavewo neakakosha kukosha kuratidza kumira. Axis inopimwa mumadhigirii uye inoreva kune iyo astigmatism iri pane iyo cornea.

Wedzera

Kuwedzera kunoshandiswa mumalensi anoverengeka kuratidza iro rekuwedzera simba rekumusoro kwechikamu che lens.

Prism

Prism inongowanikwa pane yakaderera nhamba yezvinyorwa. Iyo inoshandiswa apo chiremba wako anonzwa kuti muripo wekuenderana kwemaziso kunokosha.

Zvinyorwa pane yako girazi remaziso

Paunenge uchitarisa tsamba yako yegirazi yemaziso, unogona kuona zvakanakira lens izvo zvakabatanidzwa nachiremba wako. Izvi zvinowanzo sarudzika uye zvinogona kuwedzera mari yekuwedzera:

• Photochromic lenzi.Zvakare zvinonzi zvinoshanduka tint lenses uye mwenje-inogadziridza lenzi, izvi zvinoita kuti maalenisi aite rima kana aonekwa kune chezuva.
• Anti-inoratidza kupfeka.Iyo zvakare inonzi AR yekumhanyisa kana anti-kupenya kupenya, uku kupfeka kunodzora kuratidzika kuitira kuti mwenje upfuure nepamalenzi.
• Lenzi dzinofambira mberi.Aya ndiwo malenzi mazhinji asina mitsara.

Chinyorwa chako chegirazi remaziso hachisi chako chinyorwa chema lens

Nepo tsamba yako yegirazi yemaziso iine ruzivo rwese rwakakosha kuti iwe utenge magirazi emaziso, haina ruzivo rwakakosha pakutenga malensi ekutaurirana.

Ruzivo urwu rwunosanganisira:

• lens dhayamita
• curve yekumashure kwepamusoro kweiyo lens lens
• lens mugadziri uye zita rechiratidzo

Chiremba wako anozoitawo dzimwe nguva kugadzirisa huwandu hwesimba rekugadzirisa pakati pemagirazi uye malensi ekubatana zvichienderana nedaro iro lens richava kubva paziso. Magirazi anenge gumi nemana emamirimita (mm) kure nepamusoro peziso nepo malensi ekubatana ari akananga pamusoro peziso.

Tora woenda nazvo

Zvichienderana nemamiriro ako chaiwo - parizvino uchishandisa ekugadzirisa maziso, zera, zvinhu zvine njodzi, uye nezvimwe - vanachiremba vazhinji vemaziso vanopa kuongororwa kwese kwemaziso gore rega kana maviri.

Panguva iyoyo, kana zvichidikanwa, chiremba wako achakupa tsamba yekuti iwe ushandise pakutenga maziso. Iyi mishonga inogona kuoneka ichivhiringidza kusvikira iwe waziva zvinoreva zvirevo zvakadai seOS, OD, uye CYL.

Rangarira kuti mushonga waunowana kumagirazi emaziso hausi mushonga wemalenisi zvakare. Iwe haugone kuwana tsamba yemakemikari ekuonana kusvikira chiremba wako aita yakakodzera uye nekuongorora maziso ako 'mhinduro kune yekubata lens kupfeka.
