Kujwayelekile kakhulu, ezinjeni ezifakwe ukukhanya, ukubonakala kwe- izindawo ezinsundu noma ezibomvu ngaphansi kwamehlo. Kungenxa yokushuba komswakama okwedlulele endaweni, njengokubhidlika ngokweqile, okwenzeka lapho isilwane sithola ukuvinjelwa kwezinye izinyembezi, ukungezwani nezinto ezithile noma ezinye izinkinga zamehlo. Konke lokhu kudala uhlobo "lwe-oxidation" olubonakala ngalezi zimpawu.
I-Las izinyembezi wezinja zakhiwa ngezinto eziningana, phakathi kwazo lapho sithola i-iron ne-magnesium. Lapho zithintana nomoya, lezi zinto zihlanganisa i-oxidize, zakhe ibala elimnyama ezinweleni zesilwane sethu. Omunye wemiphumela etholakala kukho konke lokhu ukubonakala kwe- isikhunta namagciwane, okuyenza ibe yimbi kakhulu inkinga. Ngendlela efanayo, uma sihlanza le ndawo ngamanzi singaphinde sikhuthaze ukuvela kwalokhu kuguquka kombala.
Kwesinye isikhathi lokhu kudabuka okuchichimayo, okubizwa nangokuthi i-ocular epiphora, kubangelwa ukuntuleka kokudla okunomsoco, ngakho-ke kufanele siqiniseke ukuthi okuphakelayo okudliwa yinja kusezingeni eliphakeme futhi sikuhlinzeka ngamavithamini namaminerali okudingayo. Kwesinye isikhathi, ukungezwani komzimba kungenxa yento ehogelwe noma efakiwe, noma kungenzeka nokuthi umgudu wezinyembezi uvinjwe ngomunye umzimba wangaphandle (inqobo nje uma inkinga iziveza ngeso elilodwa kuphela). Ngakho-ke, kungcono kakhulu lokho udokotela wezilwane uhlola amehlo esilwane ukuqinisekisa ukuthi ayikho inkinga enjalo futhi, uma kunjalo, uqale ukwelashwa okufanele.
Kunezinye izinto eziholela ekubonakaleni kwalezi zindawo. Enye yazo umjaho, AmaPoodle namaChihuahuas yibo abajwayele ukuhlupheka kakhulu nge-epiphora. Lokhu kungachazwa ngeqiniso lokuthi izikhoxe zamehlo zalezi zinja zizacile ngokweqile, okwenza kube nzima ukugcwala izinyembezi. Ubudala Kungenye imininingwane okufanele uyinake, ngoba izinyembezi zemidlwane zinomuncu, othanda umbala obomvu, kuyilapho imisele yezinyembezi zezinja esezikhulile zivame ukuvaleka.
El uboya obuningi endaweni nayo ithanda ukudabuka, kanye amanzi ompompi. Inamaminerali amaningi kakhulu enza kube lula ukwakheka kwamabala, ngakho-ke kuzoba ngcono ukuhlinzeka isilwane ngamanzi asemabhodleleni noma ahlungiwe.
Ku-Intanethi sithola okuningi amakhambi asekhaya ukuqeda la mabala acasulayo (usawoti, ukumnika i-chamomile, i-hydrogen peroxide ...), kepha into ebaluleke kunazo zonke ukuthi, njengoba sishilo ngaphambili, siye kudokotela wezilwane ngaphambi kwesikhathi ukuze siqiniseke ukuthi isilwane sethu asihlushwa yinkinga yamehlo futhi sibuze ukuseluleka ukuthi yiliphi ikhambi elingcono kakhulu lokuqeda le nkinga.
