Ukuba ukhe wehla iinyembezi zizehlela emlonyeni, mhlawumbi uqaphele ukuba zinencasa ecacileyo enetyiwa.

Kutheni le nto iinyembezi zinetyuwa? Impendulo yalo mbuzo ilula. Iinyembezi zethu ubukhulu becala zenziwe ngamanzi asemizimbeni yethu, kwaye la manzi aneetyuwa ion (iielectrolyte).

Ewe kunjalo, zininzi ngakumbi iinyembezi ezinencasa nje yetyiwa. Qhubeka ufunda ukuze wazi ukuba zenziwe ngantoni iinyembezi, zivela phi, zikhusela njani kwaye zithambisa amehlo ethu, kwaye kutheni ukukhala okuhle kunokusenza sizive ngcono.

Zithini iinyembezi

Iinyembezi ngumxube ontsonkothileyo. NgokweZiko leLiso leLizwe (i-NEI), zenziwe zezi:

• amanzi
• yencindi
• iioyile ezinamafutha
• ngaphezulu kwe-1,500 yeeproteni ezahlukeneyo

Njani iinyembezi ziwathambise amehlo ethu

Iinyembezi zenziwa ngeendlela ezintathu ezisebenza ukuthambisa, ukondla, nokukhusela amehlo ethu:

• Uluhlu lwangaphandle. Uluhlu lwangaphandle olunamafutha luveliswa ziincindi zemeibomian. Olu luhlu lunceda iinyembezi zihlale emehlweni kwaye zigcina iinyembezi zingaphumi msinyane.
• Maleko Middle. Uluhlu lwamanzi oluphakathi lubandakanya iiprotheni ezinyibilikayo ngamanzi. Iveliswa yincindi ephambili ye-lacrimal kunye ne-accessory ye-lacrimal gland. Olu luhlu lukhusela kwaye londle i-cornea kunye ne-conjunctiva, eyona yimbumba efihla ngaphakathi kweenkophe kunye nangaphambi kweso.
• Uluhlu lwangaphakathi. Uluhlu lwangaphakathi lwe-mucous luveliswa ziiseli ze-goblet. Idibanisa amanzi ukusuka kumgangatho ophakathi, ukuvumela ukuba isasazeke ngokulinganayo ukugcina iliso lithanjisiwe.

Apho iinyembezi zivela khona

Iinyembezi ziveliswa ngamadlala abekwe ngaphezulu kwamehlo naphantsi kwamehlo akho. Iinyembezi zisasazeka ukusuka kumadlala nakumphezulu wamehlo akho.

Ezinye iinyembezi ziyakhupha ngemijelo yeinyembezi, eziyimingxunya emincinci ecaleni kweekona zamehlo akho. Ukusuka apho, baya ezantsi empumlweni.

Kunyaka oqhelekileyo, umntu uya kuvelisa i-15 ukuya kwi-30 yeelitha zeenyembezi, ngokwe-American Academy of Ophthalmology (AAO).

Iindidi zinyembezi

Zintathu iintlobo eziphambili zeenyembezi:

1. Iinyembezi ezisisiseko. Iinyembezi ezisisiseko zisemehlweni akho ngalo lonke ixesha ukuthambisa, ukukhusela kunye nokondla i-cornea yakho.
2. Iinyembezi ezinqabileyo. Iinyembezi ezinqabileyo ziveliswa ngokuphendula kwinwebu, njengokutshaya, umoya, okanye uthuli. Iinyembezi ze-Reflex yile nto siyivelisayo xa sijongana ne-syn-propanethial-S-oxide ukusuka ekusizeni i-anyanisi.
3. Iinyembezi ezingokweemvakalelo. Iinyembezi ezingokweemvakalelo ziveliswa ngokuphendula kwintlungu, kubandakanya iintlungu zomzimba, intlungu yovelwano, iintlungu zovakalelo, kunye neemeko zovakalelo, ezinje ngokudabuka, ukonwaba, uloyiko, kunye nezinye iimvakalelo.

Iinyembezi ngexesha lokulala

Ukuvuka nge-crust kwiimbombo zamehlo kuyinto eqhelekileyo. NgokweDyunivesithi yase-Utah, ezi zinto zilukhuni zixubene nezi:

• iinyembezi
• yencindi
• neeoyile
• iiseli zolusu ezikhutshiwe

Ngelixa lo mxube uhlala unyanyekelwa emini ngokuqhwanyaza, ngexesha lokulala amehlo akho ayavalwa kwaye akukhoqhwanyaza. Umxhuzulane uyayinceda iqokelele kwaye iqine kwiimbombo nasemacaleni kwamehlo akho.

Ukwenziwa kweenyembezi njengoko uneminyaka yobudala

Ngokuka, njengoko uneminyaka yobudala, iiprofayili iiprofayili zeenyembezi zakho zinokutshintsha. Kananjalo, ngokweZiko leSizwe lokuguga, iliso elomileyo- imeko ebangelwa ziincindi zinyembezi ezingenzi kwinqanaba elifanelekileyo- ixhaphake kakhulu njengabantu abadala, ngakumbi abasetyhini emva kokuyeka ukuya exesheni.

Ngaba ukukhala kungaziva ungcono

Iziphumo zokulila ziye zafundwa. Abaphandi bacinga ukuba isenzo sokukhala kunye nokuveza iimvakalelo zomntu sinokuzisa isiqabu, ngelixa ukubamba okanye ukufaka ezibhotileni iimvakalelo zethu kunokukhokelela kuxinzelelo lwengqondo.

Kukho uphando malunga nokwakheka kweenyembezi zomoya. Izazinzulu zikholelwa ukuba iinyembezi zemoya zinokuba neeproteni kunye neehormoni ezingafumaneki kwiinyembezi ezisisiseko okanye iinyembezi. Kwaye ezi hormone.

Nangona kunjalo, kufunyenwe ukuba "kukudipha kunye nokubuya okulandelayo kweemvakalelo kumanqanaba angaphambili anokwenza ukuba iziphatho zivakale ngokungathi zikwimeko ebhetele kakhulu emva kokuba ziye zalila iinyembezi."

Uphando oluthe kratya malunga neziphumo zokulila kunye nokwakheka kweenyembezi zemoya ziyafuneka ngaphambi kokuba sinqume ukuba zinokubonelela ngonyango lweemvakalelo.

Ukuthatha

Ngalo lonke ixesha uqhwanyaza, iinyembezi zakho zicoca amehlo akho. Iinyembezi zigcina amehlo akho egudile, emanzi, kwaye ekhuselekile:

• indlela eyiyo
• Okucaphukisayo
• izifo ezosulelayo

Iinyembezi zakho zinetyiwa kuba zineetyiwa zendalo ezibizwa ngokuba zii-electrolyte.
