Mhlawumbi wenza oku ngoku - ujonge ikhompyutha, ifowuni okanye ithebhulethi ekhupha ukukhanya okuluhlaza okwesibhakabhaka.
Ukuzijonga ixesha elide ezi zinto kunokukhokelela kwi-Computer Vision Syndrome (CVS), uhlobo olulodwa loxinzelelo lwamehlo olubangela iimpawu ezifana namehlo omileyo, ukubomvu, iintloko ezibuhlungu, kunye nokungaboni kakuhle.
Esinye isisombululo esicetywayo ngabavelisi bezinto zokujonga ngamehlo ziiglasi ezivala ukukhanya okuluhlaza okwesibhakabhaka. Kuthiwa zivala ukukhanya okuluhlaza okwesibhakabhaka okunokuba yingozi okukhutshwa zizixhobo ze-elektroniki. Kodwa ingaba ezi goggles ziyawunciphisa ngokwenene na umonakalo wamehlo, yinto exoxwayo.
Ukukhanya okuluhlaza okwesibhakabhaka lubude belanga obuvela ngokwemvelo ekukhanyeni, kuquka nokukhanya kwelanga. Ukukhanya okuluhlaza okwesibhakabhaka kunobude belanga obufutshane xa kuthelekiswa nezinye iintlobo zokukhanya. Oku kubalulekile kuba oogqirha baye banxulumanisa ukukhanya okufutshane nomngcipheko okhulayo wokonakala kwamehlo.
Ngelixa izixhobo ezininzi ze-elektroniki, kuquka iibhalbhu zokukhanya, zikhupha ukukhanya okuluhlaza okwesibhakabhaka, izikrini zekhompyutha kunye neethelevishini zihlala zikhupha ukukhanya okuluhlaza okwesibhakabhaka ngaphezu kwezinye izixhobo ze-elektroniki. Oku kungenxa yokuba iikhompyutha kunye neethelevishini zihlala zisebenzisa izibonisi zekristale yolwelo okanye ii-LCD. Ezi zikrini zinokubonakala zicwebezela kwaye zikhanya, kodwa zikhupha ukukhanya okuluhlaza okwesibhakabhaka ngaphezu kwezikrini ezingezizo ii-LCD.
Nangona kunjalo, i-Blu-ray ayimbi kangako. Ngenxa yokuba olu bude bexesha lwenziwa lilanga, lunokunyusa ukuphaphama, nto leyo ebonisa ukuba lixesha lokuvuka uqale usuku.
Uninzi lophando malunga nokukhanya okuluhlaza okwesibhakabhaka kunye nomonakalo wamehlo lwenziwe kwizilwanyana okanye phantsi kweemeko zelebhu ezilawulwayo. Oku kwenza kube nzima ukucacisa ngqo indlela ukukhanya okuluhlaza okwesibhakabhaka okubachaphazela ngayo abantu kwiimeko zobomi bokwenyani.
Ngokutsho kwe-American Academy of Ophthalmology, ukukhanya okuluhlaza okwesibhakabhaka okukhutshwa zizixhobo ze-elektroniki akubangeli isifo samehlo. Bakhetha ukusebenzisa ezinye iindlela zokuphucula ubuthongo babo, njengokuphepha ukubukela izikrini iyure enye okanye ezimbini ngaphambi kokuba balale.
Ukuze kuncitshiswe umonakalo kunye nemiphumo emibi enokubakho yokuvezwa kukukhanya okuluhlaza okwesibhakabhaka ixesha elide, abavelisi bezinto zokujonga amehlo baye baphuhlisa iilensi zeglasi ezineengubo ezikhethekileyo okanye imibala eyenzelwe ukubonakalisa okanye ukuthintela ukukhanya okuluhlaza okwesibhakabhaka ekufikeleleni emehlweni akho.
Ingcamango engasemva kweeglasi ezivala ukukhanya okuluhlaza okwesibhakabhaka kukuba ukuzinxiba kunokunciphisa uxinzelelo lwamehlo, umonakalo wamehlo kunye nokuphazamiseka kokulala. Kodwa akukho phando lungako oluxhasa ibango lokuba iiglasi zinokukwenza oku.
I-American Academy of Ophthalmology icebisa ukunxiba iiglasi endaweni yee-contact lenses ukuba uchitha ixesha elininzi ujonge izixhobo ze-elektroniki. Oku kungenxa yokuba ukunxiba iiglasi akunakwenzeka ukubangela amehlo omileyo nacaphukileyo xa usebenzisa ii-contact lenses ixesha elide.
Ngokwethiyori, iiglasi ezikhanyayo eziluhlaza okwesibhakabhaka zinokunceda ekunciphiseni uxinzelelo lwamehlo. Kodwa oku akuqinisekiswanga ngokupheleleyo luphando.
Uphononongo luka-2017 lujonge iimvavanyo ezintathu ezahlukeneyo ezibandakanya iiglasi ezivimba ukukhanya okuluhlaza okwesibhakabhaka kunye nokuxinana kwamehlo. Ababhali abafumananga bungqina buthembekileyo bokuba iiglasi ezivimba ukukhanya okuluhlaza okwesibhakabhaka zinxulunyaniswa nombono ophucukileyo, ukuxinana kwamehlo okuncinci, okanye umgangatho wokulala ophucukileyo.
Uphononongo oluncinci luka-2017 lubandakanya abantu abangama-36 abanxibe iiglasi ezikhanyayo eziluhlaza okwesibhakabhaka okanye abathatha i-placebo. Abaphandi bafumanise ukuba abantu abanxibe iiglasi ezikhanyayo eziluhlaza okwesibhakabhaka iiyure ezimbini besebenza kwikhompyutha babenokudinwa kancinci kwamehlo, ukurhawuzelelwa, kunye neentlungu zamehlo kunabo bangazange banxibe iiglasi ezikhanyayo eziluhlaza okwesibhakabhaka.
Kuphononongo luka-2021 lwabathathi-nxaxheba abayi-120, abathathi-nxaxheba bacelwe ukuba banxibe iiglasi zokukhusela ezikhanyayo eziluhlaza okwesibhakabhaka okanye iiglasi ezicacileyo baze bagqibezele umsebenzi kwikhompyutha othathe iiyure ezi-2. Xa olu phononongo luphela, abaphandi abafumananga mahluko ekudinweni kwamehlo phakathi kwamaqela amabini.
Amaxabiso eeglasi ezivimba ukukhanya okuluhlaza okwesibhakabhaka ezithengiswa ngaphandle kwekhawuntara aqala kwi-$13 ukuya kwi-$60. Iiglasi ezivimba ukukhanya okuluhlaza okwesibhakabhaka ezithengiswa ngomyalelo kagqirha zibiza kakhulu. Amaxabiso aya kuxhomekeka kuhlobo lwefreyimu oyikhethayo kwaye anokuqala kwi-$120 ukuya kwi-$200.
Ukuba une-inshorensi yezempilo kwaye udinga iiglasi ezikhusela ukukhanya okuluhlaza okwesibhakabhaka ezibhalwe ngugqirha, i-inshorensi yakho inokuhlawula ezinye zeendleko.
Nangona iiglasi ezivimba ukukhanya okuluhlaza okwesibhakabhaka zifumaneka kwiindawo ezininzi zokuthengisa, azixhaswa yimibutho emikhulu yamehlo.
Kodwa ukuba ufuna ukuzama iiglasi ezithintela ukukhanya okuluhlaza okwesibhakabhaka, khumbula izinto ezimbalwa:
Ukuba awuqinisekanga ukuba iiglasi ezithintela ukukhanya okuluhlaza zikulungele na, okanye ukuba zikulungele na, ungaqala ngeeglasi ezingabizi kakhulu ezikhululekileyo ukuzinxiba.
Izifundo ezininzi azikaqinisekisi ukusebenza kweeglasi ezivimba ukukhanya okuluhlaza okwesibhakabhaka. Nangona kunjalo, ukuba uhleli kwikhompyutha okanye ubukele iTV ixesha elide, usengazama ukuze ubone ukuba ziyanceda na ukunciphisa uxinzelelo lwamehlo kwaye ziphucule iimpawu ezifana namehlo omileyo kunye nokubomvu.
Unganciphisa noxinzelelo lwamehlo ngokuthatha ikhefu lemizuzu eli-10 ngeyure kwikhompyutha yakho okanye kwisixhobo sakho sedijithali, usebenzisa amaconsi amehlo, kwaye unxibe iiglasi endaweni yee-contact lenses.
Ukuba ukhathazekile ngokukhathala kwamehlo, thetha nogqirha wakho okanye ingcali yamehlo malunga nezinye iindlela eziluncedo zokunciphisa naziphi na iimpawu zokukhathala kwamehlo onokuba unazo.
Iingcali zethu zihlala zijonga impilo kunye nempilo-ntle kwaye zihlaziya amanqaku ethu njengoko kufumaneka ulwazi olutsha.
Abalawuli belizwe bavumile iVuity, amathontsi amehlo anceda abantu abangaboni kakuhle ngenxa yokwaluphala ukuba babone ngaphandle kokufunda iiglasi.
Uninzi lokukhanya okuluhlaza okwesibhakabhaka luvela elangeni, kodwa ezinye iingcali zempilo ziye zaphakamisa umbuzo wokuba ukukhanya okuluhlaza okwesibhakabhaka okwenziweyo kungonakalisa na...
