Ungawathuthukisa Kanjani Amehlo Akho Ngemizuzu engama-20 Noma Ngaphansi

Umbuzo ovela ezinkundleni zokuxhumana ucele abasebenzisi ukuthi "Bachaze kabi ukuthi wenzani ukuze uziphilise." Izimpendulo bezisukela kokuthi “Ngingene ngomnyango wakho ongaphambili bese ngifafaza zonke izinto zakho ngamanzi” (isicishi-mlilo) kuye kokuthi “Ngikhokhelwa ukuba omunye umuntu” (umlingisi). Impendulo eguquguqukayo ngezinye izikhathi engiyinikeza abantu ithi “Ngigqolozela isikrini sekhompyutha usuku lonke.” Noma ngabe umsebenzi wakho unjani noma ngabe umsebenzi wakho ungaphakathi komuntu noma ukude, bangaki bethu abangachaza imisebenzi yethu ngaleyo ndlela? Futhi uma singagqolozele isikrini sekhompuyutha, ngokuvamile sibheka amafoni ethu, amathebulethi, noma izikrini ze-TV.

Njengomphumela wokugqolozela ezikrinini, ngaphezu kwesigamu sabo bonke abantu abadala kanye nenani elandayo lezingane e-United States nakwamanye amazwe bahlushwa i-digital eye strain noma i-DES.[i] I-DES ichazwa yi-American Optometric Association “njengeqembu lezinkinga eziphathelene namehlo nezombono ezibangelwa ukusetshenziswa isikhathi eside kwamakhompiyutha, amaphilisi, ama-e-readers, nomakhalekhukhwini okudala ukucindezeleka okwandayo ekuboneni eduze ikakhulukazi. Iphinde ichaze ukufakwa kwezimpawu zamehlo, ezibonwayo nezamathambo ngenxa yokusebenzisa isikhathi eside ikhompuyutha.”[Ii]

Odokotela bamehlo babeke umthetho othi “20-20-20” ukunciphisa i-DES: njalo ngemizuzu engama-20, khipha amehlo akho esikrinini imizuzwana engama-20 bese ubheka into ekude okungenani iqhele ngamamitha angama-20.[Iii] Ikhefu elide lemizuzu engu-15 njalo ngemva kwamahora amabili liyanconywa. Yebo, uma unjengami ngiyalingeka ukuba ngichithe leso sikhathi ngibuka esinye isikrini. Ngakho-ke yini esingayenza ukuze sinikeze amehlo ethu ikhefu ngempela?

UJanuwari 20 wuSuku lokuThatha i-Walk Outdoors Day. Ukuthatha uhambo ngaphandle kuqinisekisiwe ukuthi uzogxilisa amehlo akho ezintweni okungenani ezingamamitha angama-20. Noma ngabe ukuhamba kwakho kukuyisa emigwaqweni yasemadolobheni noma emizileni yemvelo, ukushintsha indawo kuyokwenza amehlo akho akhathele abe mnandi. Njengoba sazi, iColorado iyazigqaja ngezinsuku ezingaphezu kuka-300 zokukhanya kwelanga ngonyaka kodwa ukuhamba emvuleni noma eqhweni kuyoba yinzuzo ngokulinganayo, hhayi nje emehlweni kuphela, kodwa nakinina nonke. Ukuhamba kusiza ngokuqina kwenhliziyo nemithambo yegazi, amandla emisipha namathambo, amazinga wamandla, imizwa kanye nokuqonda, kanye namasosha omzimba. Njengoba uHippocrates aphawula, “Ukuhamba kuwumuthi ongcono kakhulu.”

Ukuhamba nelungu lomndeni noma umngane kukusiza ukuthi uhlale uxhumekile futhi wakhe ubudlelwano. Izinja zingabalingani abahamba kahle kakhulu futhi zilungele nakubo. Ukuhamba wedwa nakho kungajabulisa, kungakhathaliseki ukuthi kuhambisana nomculo, ama-podcasts, ama-audiobook, noma ukucwiliswa nje emisindo yemvelo.

Ngisho nokwazi zonke lezi zinzuzo kulula ukusebenzisa izaba zokuthi simatasa kakhulu. Kodwa cabanga ngocwaningo olwenziwe yi-Microsoft Human Factors Lab. Abahlanganyeli balinganiswa ngemishini ye-electroencephalogram (EEG) phakathi nemihlangano yevidiyo elandelanayo. Labo abathathe ikhefu phakathi kwemihlangano babonise umsebenzi wobuchopho ohlanganyele kakhulu kanye nengcindezi encane uma kuqhathaniswa nalabo abangazange. Ucwaningo lwaphetha ngokuthi: “Ngamafuphi, amakhefu awasizi nje kuphela inhlalakahle, futhi athuthukisa ikhono lethu lokwenza umsebenzi wethu omuhle kakhulu.”[Iv]

Uma kukuhle emehlweni akho nempilo iyonke, futhi kukwenza uphumelele ngokwengeziwe emsebenzini wakho, kungani ungaphumuli? Noma ngibhala lokhu okuthunyelwe kwebhulogi, ngithola ukuthi ngihlangabezana nezimpawu ze-DES. Isikhathi sokuhamba ngezinyawo.
