Kutheni sifaka amehlo ethu?
Njengabantwana, ininzi lethu lalingqinela imincintiswano kunye nabantakwabo okanye abahlobo. Kuze kube nini ungabambelela ukuba ukhangele ngaphandle kokuba udibanise? Amehlo akho aqala ukutshisa kwaye amanzi waza wagqiba.
Ukuqhawula isenzo esheshayo sokuvala nokuvula ijwabu leso. Ukucoca kubalulekile ngenxa yokuba kucima utshathululi lwamathambo kwaye lubonakalise iliso.
I-blink yesilinganiso ithatha malunga ne-400 millisecond, kodwa isantya sinokuchaphazeleka ngezinto ezininzi ezifana nokukhathala, ukusetyenziswa kwamachiza kunye neemeko ezithile zempilo. Nangona mhlawumbi ungaziqapheli, umntu oqhelekileyo ukhawuleza malunga nanye ngemizuzwana eyishumi. Ubomi bomntu buyakwazi ukungahoyiki ubumnyama be-blink, okuvumela ukuba sibe nombono oqhubekayo wehlabathi.
Njengoko kuchaziwe ngasentla, isizathu esona sizathu sokuba amehlo ethu agxilwe kukusula nokutsha kwakhona ifilimu yethu yokulila. Ifilimu yethu yokulila iyanzima kakhulu kwaye yenziwe ngamanzi amaninzi. Iinyembezi zethu zenziwa ngamanzi amaninzi, ioli ne-mucus. Kwakhona, kukho amakhulu amacandelo afana nama-lysosomes asebenza njengamayeza omzimba. Kukho ezininzi izondlo kunye nama-amino acids anceda ukondla iiseli kwi-cornea, icacileyo, isakhiwo esinjengombumba phambi kweso.
Ngaphandle kokugcina amehlo ethu agcobile, ifilimu yethu yokulila nayo:
- Unceda ukwakha indawo ebonakalayo epholileyo, epholileyo kwi-cornea ukukhanya ukugxila ngokufanelekileyo
- inceda ukudlulisa i-oksijini evela emoyeni ukuya kwi- cornea , kuba akukho mithombo yegazi ukuyihambisa ngqo
- inqanda ukusuleleka ngenxa yobungqina be-lysozyme kunye nezinye i-enzyme zokulwa ne-antibacterial
- kuhlamba iindawo ezihlaziyiweyo
- inikeza indlela yeeseli ezimhlophe zegazi xa kukho ukulimala kumphezulu
Kukho iintlobo zeengqungquthela zeentlobo ezahlukeneyo kwijwabu leso. Xa iliso likhanya, kukho indlela yokucwenga ebonisa ezo zihlunu ukuze zifake izixhobo zezinyembezi. Kukho nantlukwano elincinci le-eyelidi elikhupha i-debris kwi- puncta , ifilimu yokulila ikhupha ibhobho.
Ngoko, ukubethelwa kubonakala ngathi iyona sizathu esiyinhloko esiye siyiqhawule. Nangona kunjalo, izazinzulu ziye zafumanisa ezinye izizathu zokubangela ukuba sinokuqhafaza ngokuqhelekileyo. Isazi senzululwazi sichaza ukuba sikhanyisa ngaphezu kwezinto eziyimfuneko nje ukutshaya kwakhona ifilimu yokulila. Uphononongo olugqityiwe yenzululwazi ngo-2012 lubonisa ukuba sinokukrola ngezinye izizathu.
Emva kokuphonononga uphando oluninzi, abaphandi bafumanisa ukuba ixesha elifanelekileyo xa sixhamla ayenzi ngokwenene. Bakufumanisa ukuba sifihla kwixesha eliqikelelweyo. Ngokomzekelo, xa ufunda, uninzi lwabantu lucacile ekupheleni kwesivakalisi. Xa umntu ephulaphule intetho, bavame ukukhawuleza xa isithethi simisa phakathi kweengxelo. Omnye umzekelo xa abantu bebukele ividiyo, bonke bavame ukukhankanya xa isenzo kwividiyo sidlala isikhashana.
Iyanzima kunzima, kodwa izazinzulu zivakalelwa kukuba sisebenzisa i-blinks njengendlela yokuphumla kwengqondo emfutshane ngokukhawuleza ukuvala ukubonakala kwezinto ezibonakalayo ukuze sikwazi ukugxila kwizinto ezikuyo.
Inzululwazi yafumanisa ukuba xa abantu bexhamla, imisebenzi yengqondo iqhutywe kwiindawo ezithile kwingqondo esebenzayo xa ingqondo ihlala kwindawo yokuphumla. Bavakalelwa kukuba ukusetyenziswa kwelo nxalenye yengqondo kusebenza njengophulaphulo lwengqondo olufutshane oluye lavunyelwa ukuba lucinge ngakumbi xa amehlo evuliwe kwakhona.
Abanye baye baphawula ukuba siyanqakraza ngenxa yezizathu zengqondo. Uphando olongezelelweyo luyadingeka kodwa kubonakala kucacile ukuba isimo sethu sengqondo sitshintshi xa sitshitshisa kwaye kungekhona nje ukuvuselela ifilimu yethu yokulila.
