Iso leZabantu linalo
Iliso lomntu lihle kakhulu ekufumaneni ngokuchanekileyo kunye nolwazi oluninzi malunga nehlabathi elikusijikelezayo, kodwa linokulinganiselwa. Omnye umzekelo wale ndawo iyimfama okanye inxalenye encinane kwintsi ebonakalayo ehambelana nendawo ye-optic disk ekhona ngasemva kweso. Indawo eyimfama iyindawo kwi-retina eyaziwa njenge-optic disk apho i-fibtic neriber fiber iphuma ngasemva kweso.
Kutheni Sinezipho Eziyimfama?
I-disk i-optic i-1.5 millimeters okanye i-0.06 intshi ububanzi. Ukongezelela ekubeni yinto apho i-optic yegrifu iphuma kwiso, yilapho nalapho imingxuma yegazi enkulu ingena khona ukubonelela ngegazi.
Ngenxa yokuba akukho zixhobo okanye iindonga kweli nqanaba kwi-retina, kukho isikhala esincinci kwintsimi ebonakalayo. Uqobo unalo i-gap encinane kakhulu embonweni wakho apho ukhululekile khona.
Kutheni Sisingaziboni I-Spot Spot?
Nangona kukho iindlela zokuziphoqa ukuba uqaphele le ndawo engaboniyo, ngokuqhelekileyo asiqapheli le galeko ebonakalayo kwimini yethu kwimini yemihla. Ngoba?
Abaphandi bacebise iinkcukacha ezahlukeneyo malunga nesizathu sokuba singaboni le ndawo engaboniyo. Abanye bacetyisa ukuba iliso elijongene nalo lihlawulela ulwazi olungabonakaliyo. Oku kuphakamisa ukuba xa bobabini amehlo bevulekile, iindawo ezibonakalayo zihamba kwaye zizalise ulwazi olungekho phantsi kweso.
Enye yeengcamango eziqhelekileyo ezivunyenwe kukuba ingqondo empeleni izalisa ulwazi olungekhoyo usebenzisa iziboniso ezibonakalayo kwimeko. Nangona uvala iliso elinye, indawo eyimfama ayinakukwazi ukuyijonga. Oku kungenxa yokuba ubuchopho bakho bukwazi ukubonelela ngolwazi olungabonakaliyo ukuze ungalokothi uqaphele ukuba i-gap encinane kwintsimi yakho ebonakalayo.
Ukuba unqwenela ukuba uqaphele indawo yakho eyimfama, uyakubona into ebonakalayo kwisenzo kulo mboniso.
Ngaba Unokuyinciphisa iSiphene Sakho Esiyimfama?
Okumangalisa kukuba, abaphandi baye bafumanisa ukuba ngokwenene unokukwazi ukuphazamisa indawo oyimfama ngokusebenzisa ukuqeqeshwa kwamehlo athile.
Kwisifundo esincinci esabandakanya abathathi-nxaxheba aba-10 kuphela, abaphandi bafumene ukuba ukusebenzisa izilingo ezithile zamehlo kunokunciphisa indawo engaboniyo ngama-10 ekhulwini.
Izenzo ezisetyenziswe kwisifundo zibandakanya umfanekiso wesincinci esincinci ngqo kwindawo yomntu oyimpumputhe kunye nokubonisa amaza emigqabini ekhanyayo kunye emnyama ejikelezayo. Abathathi-nxaxheba baceliwe ukuba banqume indlela ehamba ngayo amabhanti kunye nombala wendandatho.
Ubungakanani bendandatho yaqhutyelwa ukuba ekuqaleni kweso sifundo, ifunyanwe malunga neepesenti ezingama-70 zexesha, abaphandi baguqula ubukhulu kangangokuba ekugqibeleni kuncinci bekufihliwe ngokupheleleyo ngendawo ephosakeleyo. Emva kwexesha, abathathi-nxaxheba babekwazi ukufumana umfanekiso omncinci kwindawo yabo engaboniyo kunye nokugweba umbala wendandatho kunye nesalathiso seendidi ezihambayo.
Ukunciphisa ubukhulu bendawo eyimfama bubonisa ukuphuculwa kancinci kumbono.
Abaphandi bacetyisa ukuba olu phuculo luya kuba luncinci kangangokuba abantu babengeke bakubone oko, ngenxa yokuba abaninzi abantu abaqapheli nendawo yabo engaboniyo. Nangona kunjalo, iziphumo zinokuvula iindlela ezintsha zokuphatha iintlobo ezithile zeengxaki ezibonakalayo.
Uvavanyo lweSpump Blunt
Njengoko ufundile, indawo eyimfama iyindawo ekutheni yakho engenayo i-retreat receptors. Ngenxa yoko, kukho i-gap encinane kwintsimi yakho ebonakalayo. Nangona ubuchopho bakho buzalisa ulwazi olungekho phantsi ukuze ungayiboni, olu vavanyo olukhawulezayo nolulula lukwazi ukubonisa indawo engaboniyo.
Vula le mfanekiso kwenye iwindow.
Qala ngokugubungela iso lakho lasekhohlo kwaye ukhangela inkwenkwezi ngesiliso sakho sokunene. Kancinci usondele phambili kwaye usondele kwikhompyutheni yakho yekhompyutheni, lonke ixesha ukhangele inkwenkwezi.
Ngexesha elithile, uya kuphawula ukuba isetyhula echaphazelekayo iya kulahla. Kungenxa yokuba kusempumputhe yakho! Ukuba uhamba usondele ngakumbi kwisikrini, ifowuni iya kuvela ngokukhawuleza xa ihamba ngaphandle kwindawo eyimfama kwi-retina yakho.
Unokwenza into efanayo ngenye iso. Ngeli xesha, gqubuthela iliso lakho lasekunene kwaye ujonge kwi-circular dot ngelihlo lakho lasekhohlo. Sondela kufuphi kweso siqendu de ukuba inkwenkwezi iphele ngokukhawuleza.
Qinisekisa ukuba uhlolisise iifriji zethu zeengcamango ezibonakalayo . Funda indlela abasebenza ngayo kunye noko bavezayo malunga nengqondo.
