Uma ngabe uke wehla izinyembezi zehla ezihlathini zakho ziye emlonyeni wakho, mhlawumbe uqaphele ukuthi zinokunambitheka okunosawoti ocacile.

Manje kungani izinyembezi zinosawoti? Impendulo yalo mbuzo ilula impela. Izinyembezi zethu zenziwa kakhulu ngamanzi asemizimbeni yethu, futhi la manzi aqukethe ama-ion kasawoti (ama-electrolyte).

Vele, kunokunye okuningi izinyembezi okuwukunambitheka kasawoti nje. Qhubeka ufunde ukuze ufunde ukuthi izinyembezi zenziwa ngani, zivelaphi, zivikela kanjani futhi zigcobe amehlo ethu nokuthi kungani ukukhala okuhle kungasenza sizizwe singcono.

Izinyembezi zenziwa ngani

Izinyembezi ziyinhlanganisela eyinkimbinkimbi. Ngokusho kweNational Eye Institute (NEI), zakhiwa:

• amanzi
• amafinyila
• amafutha anamafutha
• amaprotheni angaphezu kuka-1,500

Izinyembezi zithambisa kanjani amehlo ethu

Izinyembezi zenziwa ngezendlalelo ezintathu ezisebenza ukuthambisa, ukondla, nokuvikela amehlo ethu:

• Isendlalelo sangaphandle. Isendlalelo sangaphandle esinamafutha sikhiqizwa yizindlala ze-meibomian. Lolu ungqimba lusiza izinyembezi ukuthi zihlale esweni futhi zigcine izinyembezi zingahwamuki ngokushesha okukhulu.
• Isendlalelo esiphakathi. Isendlalelo esiphakathi samanzi sifaka phakathi amaprotheni ancibilikiswa ngamanzi. Ikhiqizwa yi-lacrimal gland eyinhloko kanye nezindlala ze-lacrimal zokufinyelela. Lolu ungqimba luvikela futhi londle i-cornea ne-conjunctiva, okuwulwelwesi lwamafinyila olumboza ingaphakathi lamajwabu amehlo nangaphambili lamehlo.
• Isendlalelo sangaphakathi. Ungqimba lwangaphakathi lwama-mucous lukhiqizwa ngamaseli e-goblet. Ibopha amanzi kusuka kungqimba oluphakathi, evumela ukuthi lisabalale ngokulingana ukugcina iso lithanjisiwe.

Lapho izinyembezi zivela khona

Izinyembezi zikhiqizwa yizindlala ezitholakala ngaphezu kwamehlo nangaphansi kwezinkophe zakho. Izinyembezi zigeleza zisuka kwizindlala nakuso sonke iso lakho.

Ezinye zezinyembezi ziyakhipha ngemigudu yezinyembezi, okuyizimbobo ezincane eduze kwamakhona amajwabu amehlo akho. Ukusuka lapho, zehlela ekhaleni lakho.

Ngonyaka ojwayelekile, umuntu uzokhipha amalitha wezinyembezi ali-15 kuye kwangama-30, ngokusho kweAmerican Academy of Ophthalmology (AAO).

Izinhlobo zezinyembezi

Kunezinhlobo ezintathu eziyinhloko zezinyembezi:

1. Izinyembezi eziyisisekelo. Izinyembezi ezingaphansi zisemehlweni akho ngaso sonke isikhathi ukugcoba, ukuvikela, nokondla i-cornea yakho.
2. Izinyembezi ze-Reflex. Izinyembezi ze-Reflex zenziwa ngokuphendula ukucasuka, okufana nentuthu, umoya, noma uthuli. Izinyembezi ze-Reflex yilokho esikukhiqizayo lapho sibhekene ne-syn-propanethial-S-oxide kusuka ekusikeni u-anyanisi.
3. Izinyembezi ezingokomzwelo. Izinyembezi ezingokomzwelo zikhiqizwa ukuphendula ubuhlungu, kufaka phakathi ubuhlungu obungokomzimba, ubuhlungu bokuzwelana, ubuhlungu bemizwa, kanye nezimo ezingokomzwelo, njengokudabuka, injabulo, ukwesaba, nezinye izimo ezingokomzwelo.

Izinyembezi ngesikhathi sokulala

Ukuvuka nge-crust emakhoneni wamehlo akho kujwayelekile. Ngokusho kwe-University of Utah, lezi zingcezu eziqinisiwe ngokuvamile ziyingxube ye:

• izinyembezi
• amafinyila
• amafutha
• amangqamuzana esikhumba akhishwe emzimbeni

Ngenkathi lokhu kuhlanganiswa kuvame ukunakekelwa phakathi nosuku ngokucwayiza, ngesikhathi sokulala amehlo akho avalekile futhi akukho ukucwayiza. Amandla adonsela phansi ayayisiza ukuthi iqoqe futhi iqine emakhoneni nasemaphethelweni wamehlo akho.

Ukwakheka kwezinyembezi njengoba ukhula

Ngokuya nge, njengoba ukhula, amaphrofayli amaphrofayili wezinyembezi zakho angashintsha. Futhi, ngokweNational Institute of Aging, iso elomile - isimo esidalwa yizindlala zezinyembezi ezingenzi ezingeni elifanele - sivame kakhulu njengoba abantu beguga, ikakhulukazi kwabesifazane ngemuva kokunqamuka kokuya esikhathini.

Ingabe ukukhala kungenzeka uzizwe ungcono

Imiphumela emihle yokukhala ifundwe kuyo. Abaphenyi bacabanga ukuthi isenzo sokukhala nokuveza imizwa yomuntu singaletha ukukhululeka, kuyilapho ukubamba noma ukufaka imizwa emabhodleleni kungaholela ekucindezelekeni kwengqondo.

Kukhona futhi nocwaningo mayelana nokwakheka kwezinyembezi ezingokomzwelo. Ososayensi bakholelwa ukuthi izinyembezi ezingokomzwelo zingaqukatha amaprotheni namahomoni angavamisile ukutholakala kwezinye izinyembezi ezingaphansi. Nala mahomoni.

Kodwa-ke, kutholakale ukuthi "ukubuyela emuva kanye nokulandela okulandelayo kwemizwa emazingeni adlule okungenza iziphathi zizwe sengathi zisesimweni esingcono kakhulu ngemuva kokukhala izinyembezi."

Ucwaningo oluningi ngemiphumela yokukhala nokwakheka kwezinyembezi ezingokomzwelo kuyadingeka ngaphambi kokuthi sinqume ukuthi bangakunikeza yini ukwelashwa okungokomzwelo.

Ukuthatha

Njalo lapho ucwayiza, izinyembezi zakho zihlanza amehlo akho. Izinyembezi zigcina amehlo akho ebushelelezi, enomswakama, futhi evikelekile ku:

• imvelo
• okucasulayo
• izifo ezithathelwanayo

Izinyembezi zakho zinosawoti ngoba ziqukethe usawoti wemvelo obizwa ngama-electrolyte.
