Nearsightedness

Kuona kusingaonekwi ndipo apo chiedza chinopinda muziso chakatariswa zvisizvo. Izvi zvinoita kuti zvinhu zviri kure zviite sezvisina kujeka. Nearsightedness rudzi rwekufungidzira kukanganisa kweziso.

Kana iwe uri pedyo kuona, iwe uchinetseka kuona zvinhu zviri kure kure.

Vanhu vanokwanisa kuona nekuti chikamu chepamberi cheziso chinokombama (chinodzokorodza) mwenje uye chinotarisa pane iro retina. Uku ndiko mukati mekuseri kwenzvimbo yeziso.

Kuona kusingaoneki kunoitika kana paine kusawirirana pakati pesimba rekutarisa kweziso uye nekureba kweziso. Mwenje yechiedza yakatarisa pamberi peiyo diso, pane kungonanga pairi. Nekudaro, izvo zvaunoona zvakadzima. Mazhinji esimba rinotarisa simba rinouya kubva ku cornea.

Kuona kusingaoneki kunokanganisa varume nevakadzi zvakaenzana. Vanhu vane nhoroondo yemhuri yekuona padhuze vane mukana wekukudziridza. Mazhinji maziso ane kuona pedyo ane hutano. Nekudaro, vashoma vanhu vane kutarisisa kwakanyanya vanogadzira chimiro chekudzikira kweziso.

Iyo yakanyanya kuwanda wavelength yechiedza munharaunda yako inogona kukanganisa kuvandudza myopia. Ongororo ichangobva kuitika inoratidza kuti yakawanda nguva yekunze inogona kutungamira kune mashoma myopia.

Munhu anoona zviri pedyo anoona zvinhu zvepedyo zvakajeka, asi zvinhu zviri kure zvakakanganiswa. Kubvongodza kunowanzoita kuti zvinhu zviri kure zviite sezviri pachena.

Kuona kusingaone kunowanzoonekwa muvana vane makore ekuchikoro kana vachiri kuyaruka. Vana kazhinji havagone kuverenga bhodhi, asi vanogona kuverenga bhuku zviri nyore.

Kuona pedyo kunowedzera zvakanyanya mukati memakore ekukura. Vanhu vari kuona zviri pedyo vangangoda kuchinjisa magirazi kana malenzi emagetsi kazhinji. Kuona zviri pedyo kazhinji kunorega kufambira mberi semunhu anomira kukura mumakore ake ekutanga makumi maviri.

Zvimwe zviratidzo zvinogona kusanganisira:

• Eyestrain
• Musoro (zvisingawanzoitika)

Munhu anoona zviri pedyo anogona kuverenga zviri nyore Jaeger yezati chati (iyo chati yekuverenga padyo), asi anonetseka kuverenga iyo Snellen ziso chati (chati yedaro).

Kuongorora kwese kwemaziso, kana ongororo yemeso ophthalmic inogona kusanganisira:

• Ziso kumanikidza kuyerwa (tonometry)
• Refraction bvunzo, kuona yakaringana mishonga yemagirazi
• Kuongorora kweRetinal
• Slit-mwenje bvunzo yezvivakwa kumberi kwemeso
• Kwayedza yekuona kwemavara, kutsvaga inogona kupenya ruvara
• Kuyedzwa kwemhasuru dzinofambisa maziso
• Kutaridzika kuona, vese vari kure (Snellen), uye vhara kumusoro (Jaeger)

Kupfeka magirazi emaziso kana malensi ekutaurirana kunogona kubatsira kuchinjisa kutarisisa kwechiedza chemwenje wakananga pa retina. Izvi zvinogadzira mufananidzo wakajeka.

Kuvhiya kwakanyanya kugadzirisa myopia ndeyeLASIK. An excimer laser inoshandiswa kugadzirisa (flatten) iyo cornea, kuchinjisa tarisiro. Rudzi rutsva rwekuvhiya kweraser refraction runonzi SMILE (Small Incision Lenticule Extraction) inobvumidzwawo kushandiswa muU.S.

Kutanga kuongororwa kwekuona pedyo kwakakosha. Mwana anogona kutambura munharaunda uye nedzidzo nekutadza kuona zvakanaka kure.

Zvinetso zvinogona kusanganisira:

• Corneal ulcers uye hutachiona hunogona kuitika muvanhu vanoshandisa lenzi dzekuonana.
• Kazhinji, matambudziko ekugadziriswa kwemaonero e-laser anogona kuitika. Izvi zvinogona kuve zvakakomba.
• Vanhu vane myopia, mune zvisingawanzoitika zviitiko, vanokudziridza matomu ehuremu kana kuora kwetsinga.

Fonera wako mupi wezvehutano kana mwana wako achiratidza zviratidzo izvi, izvo zvinogona kuratidza dambudziko rekuona:

• Kuomerwa nekuverenga bhodhi kuchikoro kana zviratidzo pamadziro
• Kubata mabhuku padyo padyo nekuverenga
• Kugara padhuze neterevhizheni

Fonera chiremba weziso kana iwe kana mwana wako achiona padhuze uye achiona zviratidzo zvekukanganisa kwetsvo kana musodzi, kusanganisira:

• Mwenje inopenya
• Mafashama anoyerera
• Kamwe kamwe kurasikirwa kwechero chikamu chemunda wekuona

Zvagara zvichitendwa kuti hapana nzira yekudzivirira kuona pedyo. Kuverenga uye kutarisa terevhizheni hazvikonzere kuona pedyo. Munguva yakapfuura, anodonhedza madonhwe eziso akarongerwa semushonga wekudzora kukura kwekuona pedyo muvana, asi izvo zvidzidzo zvekutanga zvaive zvisina kukwana. Nekudaro, pane ruzivo rwechizvino-zvino rwekuti mamwe maziso ekuwedzeredza anoshandiswa mune vamwe vana panguva chaiyo, anogona kudzikisira huwandu hwese hwekuona padyo kwavanozoita.

Iko kushandiswa kwemagirazi kana malenzi emagetsi hakukanganise kufambira mberi kweiyo myopia - ivo vanongotarisa mwenje kuitira kuti munhu ari pedyo aone zvinhu zviri kure zvakajeka. Nekudaro, zvakakosha kuti usape magirazi kana malenzi akasimba zvakanyanya. Malenzi akaomarara ekubata dzimwe nguva anovanza kufambira mberi kwekuona padyo, asi maonero acharamba achiwedzera "pasi" peiyo lens rekubata.

Myopia; Kufungidzira; Refractive kukanganisa - kuona pedyo

• Kuona acuity bvunzo
• Zvakajairika, kuona pedyo, uye kuona zviri kure
• Lasik kuvhiyiwa kwemaziso - akateedzana
