Ipfungwa yakanaka kubata pakutenga chipfeko chinoyevedza chinoenderana neruvara rweziso remwana wako - zvirinani kusvikira mudiki wako asvika zuva ravo rekuzvarwa rekutanga.

Imhaka yekuti maziso aunotarisa pakuzvarwa anogona kutaridzika kunge akasiyana pa3, 6, 9, uye kunyange nemwedzi gumi nemaviri ekuberekwa.

Saka usati wanyatsobatana neaya ane mwedzi mitanhatu-yakasvibirira maziso, ingo ziva kuti vamwe vacheche vanozoona shanduko kusvika pagore rimwe zera. Vamwe vara reziso revadiki vanotoenderera vachichinja huni kusvika vasvitsa makore matatu.

Maziso emucheche anochinja rini?

Yekutanga zuva rekuzvarwa kwemwana wako chiitiko chakakosha, kunyanya kana vakasvika pakunyura mukeke kekutanga. Asi zvakare zvezera iro raunogona kutaura zvakachengeteka kuti ziso remwana wako rakaiswa.

"Kazhinji, maziso emucheche anogona kuchinja ruvara mukati megore rekutanga rehupenyu," anodaro Benjamin Bert, MD, ophthalmologist paChirangaridzo Care Orange Coast Medical Center.

Zvakadaro, Daniel Ganjian, MD, chiremba wevana kuProvidence Saint John's Health Center, anoti shanduko dzakakosha zvikuru muvara dzinoitika pakati pemwedzi mitatu ne6.

Asi hue yaunoona pamwedzi mitanhatu inogona kunge ichiri basa riri kuenderera mberi - zvinoreva kuti unofanira kumirira mwedzi mishoma (kana kupfuura) usati wazadza chikamu chemavara eziso chebhuku remucheche.

Kunyangwe iwe usingakwanise kufanotaura zera chairo ruvara rwemaziso emwana wako ruchave rwechigarire, iyo American Academy yeOphthalmology (AAO) inoti vacheche vazhinji vane vara reziso rinozotora hupenyu hwavo panguva yavanenge vava nemwedzi mipfumbamwe. Zvisinei, vamwe unokwanisa kutora kusvika pamakore matatu kuti ugadzikane muvara weziso wechigarire.

Uye kana zvasvika paruvara maziso echecheche ako anozotora, izvo zvipingamupinyi zvakaunganidzwa mukufarira maziso ebrown. IAAO inotaura kuti hafu yevanhu vese muUnited States vane maziso mashava.

Kunyanya zvakanyanya, ongororo ya2016 inosanganisira 192 vacheche vakawana kuti kuwanda kwekuzvarwa kweiri iris ruvara kwaive:

• 63% shava
• 20.8% yebhuruu
• 5.7% girini / hazel
• 9.9% isingagumi
• 0.5% chikamu heterochromia (musiyano muvara)

Vatsvakurudzi vakaona zvakare kuti paive nevazhinji vachena / vacheche veCaucasus vane maziso ebhuruu uye vazhinji veAsia, Native Hawaiian / Pacific Islander, uye Vechidiki / veAmerican vacheche vacheche vane maziso e brown.

Iye zvino zvaunenge uine nzwisiso irinani yekuti maziso emwana wako anogona kuchinja ruvara (uye ave zvachose), unogona kunge uchinetseka kuti chii chiri kuitika kuseri kwezviitiko kuti shanduko iyi iitike.

Chii chine melanin chine chekuita nemuvara weziso?

Melanin, rudzi rwe pigment iyo inobatsira kune rako bvudzi uye ganda ganda, zvakare inoita basa mune iris ruvara.

Nepo mamwe maziso evacheche ari ebhuruu kana grey pakuzvarwa, sekudzidza kuri pamusoro kwakaratidza, mazhinji akatsvuka kubva pakutanga.

Sezvo melanocyte muiri iris anopindura kuchiedza uye achiviga melanin, iyo American Academy of Pediatrics (AAP) inoti ruvara rwe irises yemucheche ichatanga kuchinja.

Meso ayo ari erima mumvuri kubva pakuberekwa anowanzo gara akasviba, nepo mamwe maziso ayo akatanga akareruka mumvuri anozosviba zvakare sekugadzira kwe melanin kunowedzera.

Izvi zvinowanzoitika pamusoro pegore ravo rekutanga rehupenyu, nekuchinja kwemavara kuchinonoka mushure memwedzi mitanhatu. Chishoma chemelanin chinoguma nemaziso ebhuruu, asi wedzera chakavanzika uye mwana anogona kupedzisira ave neakasvibira kana maziso e-hazel.

Kana mwana wako aine ziso rakasvibira, unogona kutenda anoshanda nesimba melanocytes nekuvanza yakawanda melanin kuti ibudise iyo yakasviba ruvara.

"Ndiyo melanin granules yakaiswa muiris yedu iyo inotipa yedu yeziso," anodaro Bert. Uye kana uine melanin yakawanda, maziso ako anova nerima.

"Iyo pigment iri yese yakasviba nechitarisiko, asi huwandu huripo muiri iris hunogona kuona kana uine maziso ebhuruu, girini, hazel, kana shava," anotsanangura.

Izvo zvakati, Bert anonongedza kuti kunyangwe mukana wekuti maziso achinje ruvara zvinoenderana nekuwanda kwe pigment yavanotanga nayo.

Ma genetics anoita sei muziso reziso

Iwe unogona kutenda genetics yeye rako ziso ruvara. Ndokunge, genetics iyo vabereki vese vanopa.

Asi usati waenda kumusoro uchizvirovera wega kuti upfuure pameso ako epepuru, iwe unofanirwa kuziva kuti harisi chete geni rimwe rinosarudza rako diki ziso ziso. Iwo magen'a mazhinji anoita mukubatana.

Muchokwadi, iyo AAO inoti yakawanda semageneti gumi nematanhatu akasiyana anogona kuve nechekuita, nemajeni maviri akajairika ari OCA2 neHERC2. Mamwe majeni anogona kuwiriraniswa nemajini maviri aya uye nekugadzira kuenderera kwemavara eziso mune vanhu vakasiyana, sekureva kweGenetics Kumba Referensi.

Kunyangwe zvisingawanzoitika, ndosaka vana vako vangave nemaziso ebhuruu kunyangwe iwe nemumwe wako muine brown.

Pamwe, vabereki vaviri vane maziso ebhuruu vanozove nemwana ane maziso ebhuruu, kungofanana nevabereki vaviri vane maziso ebrown vangangove nemwana ane maziso eziso-bhuru.

Asi kana vese vabereki vaine maziso e brown, uye sekuru vane maziso ebhuruu, iwe unowedzera mikana yekuve nemwana ane ziso rebhuruu, sekureva kweAAP. Kana mumwe mubereki aine maziso ebhuruu uye mumwe wacho aine shava, kubhejera kune iro ruvara rwemaziso emucheche.

Zvimwe zvikonzero maziso emwana wako anochinja mavara

"Humwe chirwere cheziso chinogona kukanganisa ruvara kana chikabatanidza iris, inova iringi yemhasuru yakatenderedza mudzidzi inodzora kondirakiti yemukomana uye kutetepa patinobva kune [rima] tichienda kunzvimbo ine chiedza, uyezve," anodaro Katherine Williamson, MD, FAAP.

Mienzaniso yezvirwere zvemaziso izvi zvinosanganisira:

• albinism, uko maziso, ganda, kana bvudzi zvine zvishoma kana kushaya ruvara
• aniridia, kusavapo kwakakwana kana kusarudzika kweiyo iris, saka iwe uchaona shoma kana kusava neruvara rweziso uye, pachinzvimbo, hombe kana misshapen mwana

Zvimwe zvirwere zvemaziso hazvioneke, zvakadaro, sekusviba kwemavara kana glaucoma.

Heterochromia, inozivikanwa neirisisi isingafanane neruvara mune mumwe munhu, inogona kuitika:

• pakuzvarwa nekuda kwemajini
• semhedzisiro yeimwe mamiriro
• nekuda kwedambudziko panguva yekuvandudza maziso
• nekuda kwekukuvara kana kushungurudzika kuziso

Nepo vacheche vese vachikura pamitengo yakasiyana, nyanzvi dzinoti kana iwe ukacherekedza mavara maviri eziso akasiyana kana kujekesa kweziso reziso nemwedzi mitanhatu kana minomwe yemazera, ipfungwa yakanaka kubata chiremba wevana vako.

Tora woenda nazvo

Mwana wako anozoona shanduko zhinji mukati megore ravo rekutanga rehupenyu. Kumwe kwekuchinja uku iwe unogona kuve nekutaura mukati, nepo kumwe kwacho kuri zvachose kunze kwesimba rako.

Kunze kwekupa magene ako, hapana zvakawanda zvaunogona kuita kukanganisa vara remaziso emwana wako.
