Sonke sikhononda ngezinkinga zamehlo ngezikhathi ezithile, kodwa ukuhlushwa kwamehlo kusho ukuthini ngempela? Amehlo ethu ahlukumezeka kanjani? Njengodokotela wezilanga, ngizwa isikhalazo sobunzima bamehlo nsuku zonke, kaningi izikhathi eziningana ngosuku.
Ukucindezeleka kwamehlo kuyimpawu evezwa ngabantu lapho amehlo abo ezwa bekhathele futhi ekhulile. Abanye abantu bathi bafuna ukuvala amehlo abo bese belala lapho benesifo.
Bazizwa bephelile. Ngezinye izikhathi, ukucindezeleka kwamehlo kungakunikeza ikhanda noma kungenza ube nesidlova. Ake sihlole izimbangela eziningana zokuhluleka.
Ukukhathala Komzimba weCiliary
Ukucindezeleka kwamehlo kubangelwa izinto ezahlukene. Okokuqala, noma nini lapho wenza umsebenzi oseduze (emsebenzini oseduze), umzimba we-ciliary, umsila otholakala ngaphakathi kweso, uphoqeleka ukuba usebenze isikhathi esengeziwe. Umzimba we-ciliary yi-muscle yokugxila futhi uvumela abantu ukuba bagxile ezintweni eziseduze. Uma ubheka noma ugxila entweni entsha, lezo zinkontileka ze-muscle futhi uvumela i-lens ukuba yande futhi ikhulise amandla esiphetho iso.
Ukukhathala kwe-Extraocular Muscle
Esinye isisindo semisipha esivumelwaneni lapho sondeza eduze komsebenzi kungumsizi we- extraocular . Kunemisipha eyisithupha ye-extraocular iso ngalinye. Eminye yalezi, i-recti yomphakathi, yenza umsebenzi omningi lapho ugxile ezintweni eziseduze. Ukugcina isithombe sigxile futhi kukuvimbele ukuthi ungaboni kabili, i-recti yangaphakathi yenza ukuba amehlo aguquke ngaphakathi.
Kanti futhi, lapho lezi zinhlanzi zisebenza isikhathi eside, amehlo angase azizwe ehlile. Enye into ebangela ukucindezeleka kwamehlo lapho ibuka emuva nangaphezulu isikhathi eside. Isibonelo, asho ukuthi ukopisha iphepha owehla eceleni kwakho futhi kufanele ubheke emuva nangaphezulu ukuthayipha umbhalo obhaliwe kukhompyutha.
Ukunyakaza kwamehlo okuhlala njalo kungabangela ukucindezeleka kwamehlo okuphawulekayo. Ngaphezu kwalokho, igqoka isimo sakho sengqondo. Ukubuka njalo emuva nangaphezulu kuqala ukwenza ubuchopho bakho buzwe bukhathele futhi.
Izifo Eziphezulu Ze-Ocular
Ukucindezeleka kweso kungabuye kuvela kumuntu ovame ukubhekwa kakhulu. Abantu bavame ukukhalaza ngeso lengqondo ngemva kokufunda isikhathi eside. Kwezinye izimo, kungase kungabi ukugxila kweso elibangela inkinga kodwa kunalokho iso elomile elibangela. Njalo uma sigxila kwesikrini sekhompyutheni noma nje sifunda incwadi isikhathi eside, izinga lethu lokukhanya liyancipha. Noma kunini lapho sigxila ezintweni ezithile izinga lethu lokukhanya liyehla. Uma singabonakali ngokujwayelekile, ifilimu yethu yezinyembezi eziyinkimbinkimbi ayivuseleli. Uma amehlo ethu engagcini kahle, bazizwa bekhathele futhi behlushwa.
Izinkinga Umbono Ongalungile
Enye imbangela yenkinga yamehlo yinkinga yombono engaqondakali. Izinkinga ezincane zemibono ezingalungile zibi kakhulu kunokuba nenkinga enkulu yombono. Uma umuntu enenkinga enkulu yombono, azama ngisho nokuzama. Bavame ukuyeka bese beya kudokotela wezilwane ngoba abakwazi ukusebenza. Uma unenkinga encane yemibono engaqondakali, uzama ukukhokhela ngokukhipha futhi ugxile kanzima.
Ukuzama ukukhokhela kungabangela ukuphazamiseka kokuhlala futhi kukushiye ukhathele ekupheleni kosuku.
Glare
I-glare engadingeki ingabangela ukucindezeleka kwamehlo. I-Glare iyimbangela ebonakalayo ebangelwa ukukhanya okungapheli nokungalawulwa. Ngezinye izikhathi i-glare ingaba yingozi kakhulu. Abaqashi abaningi basebenzisa imali eningi ukubeka iziteshi zomsebenzi ezinhle kwabasebenzi babo. Noma kunjalo, bayakhohlwa ngokuphelele ukulungisa uhlobo olufanele lokukhanyisa kwezinye izindawo zomsebenzi. Uhlobo olufanele lokukhanyisa lungadala konke umehluko ekukhiqizeni kwabasebenzi. Nakuba abahloli bethu bekhompyutha bekhwalithi engcono kakhulu manje kuneminyaka embalwa eyedlule, ukukhanyisa okujwayelekile okwenziwe nge-fluorescent ngezinye izikhathi kungabangela i-glare eyenza imvelo engakhululekile kakhulu.
Iningi lokuqhaqhaqhaqhaza elivela phansi livela elangeni ngenkathi ushayela uye emsebenzini. Eqinisweni, ingahlehlisa ukubonakala okuningi kangangokuthi ingaba yingozi.
