Mshayeli, hlola ukubona kwakho
Kukangaki abashayeli behlola umbono wabo? Ngokuvamile lapho ufaka isicelo selayisense yokushayela. Kamuva, uma kungekho ukukhubazeka kokubona okutholwayo kulesi sigaba, akusadingeki ukuba zenze lokhu futhi zingakwelula ukubona okufiphele. Abashayeli abangaboni kahle babona izimpawu sekwephuzile kakhulu lapho beshayela ngaphandle kwezibuko noma amalensi okuxhumana, okungaholela ekushintsheni kungazelelwe kanye nezimo zokushayela eziyingozi.
Uma singaboni noma yiziphi izimpawu zokuwohloka kombono, kufanelekile ukuhlola umbono wethu okungenani kanye njalo eminyakeni emi-4, ngoba ukukhubazeka kungase kuvele noma kujule. Lokhu kufanele kwenziwe kaningi kubashayeli abangaphezu kweminyaka engama-40, ngoba ikakhulukazi lapho kunengozi yokungaboni.
Umshayeli wemoto onokukhubazeka kokubona kwe- -1 diopter (ngaphandle kokulungiswa) ubona uphawu lomgwaqo kuphela ebangeni elingamamitha ayi-10. Umshayeli ongenakho ukukhubazeka kokubona noma ohamba ngezingilazi ezilungisayo noma amalensi angakwazi ukubona uphawu lomgwaqo ebangeni elicishe libe ngamamitha angu-25. Leli yibanga elivumela isikhathi esanele sokuzivumelanisa nohambo nezimo eziboniswa uphawu. Uma sinokungabaza, kufanelekile ukuthi sizihlole thina futhi sizihlole ukuthi singakwazi yini ukufunda izinombolo zelayisensi ukusuka ebangeni elingamamitha angama-20. Uma umshayeli engakuphasanga lokhu kuhlolwa, kufanele ahlole umbono wakhe udokotela wamehlo, weluleka umqondisi wesikole sokushayela iRenault, uZbigniew Vesely.
Kwenzeka ukuthi ukulahlekelwa kwe-acuity ebonakalayo kungokwesikhashana futhi kuhlotshaniswa nokusebenza ngokweqile. Izimpawu ezivame kakhulu ukuvutha kwamehlo, amehlo agcwele amanzi kanye “nomuzwa oyisihlabathi.” Esimweni esinjalo, kufanelekile ukwenza izivivinyo eziningana ukuze unciphise ukungezwani kwebhola leso, isibonelo, ukudweba izibalo eziyisishiyagalombili emoyeni ngamehlo akho noma ukugxilisa amehlo akho izikhathi eziningana ezintweni eziqhele ngamasentimitha ambalwa ukusuka kithi, bese kuthi ibanga. Ngale ndlela umbono wethu uzoba nokuphumula kancane. Uma izimpawu ziqhubeka futhi uphumule futhi ukuvivinya umzimba akusizi, ukungaboni kahle kwakho kombono kufanele kuhlolwe.
Uma umshayeli kutholakala ukuthi unenkinga yokubona, kufanele akhumbule njalo ukugqoka izibuko ezifanele noma abathintwayo lapho eshayela. Kuyafaneleka ukuba nezibuko ezisele emotweni. I-Visual acuity ibalulekile ekuphepheni emgwaqeni.
