Namuhla, sichitha isikhathi esiningi sinamathele ezikrinini, kungaba ngomsebenzi noma ngokuzijabulisa nje. Lesi simo siholele edume kakhulu "i-screen syndrome" kuba yinto yansuku zonke, ethinta ingxenye enkulu yabantu abanomuzwa wokuthi amehlo abo awasakwazi ukubekezelela lutho ngemva kosuku olunzima ehhovisi noma ekuphequluleni izinto ngeselula.
Kubalulekile ukuqonda ukuthi lo muzwa wokukhathala awusona isifo esibi kakhulu, kodwa kunalokho impendulo yomzimba wethu ukuzikhandla ngokweqile. Nakuba kungeke kubangele umonakalo ohlala njalo uma kwelashwa ngesikhathi, ukunganaki lezi zimpawu kungagcina kubangele ubuhlungu bekhanda obungapheli noma ukwehla okuphawulekayo komkhiqizo wethu wansuku zonke.
Kuyini ngempela ukukhathala kwamehlo futhi kuhluke kanjani ku-presbyopia?
Abantu bavame ukudidanisa ukucindezelwa kwamehlo ne-presbyopia, kodwa akufani. Nakuba i-presbyopia iyi- inqubo yokuguga yemvelo Uma ilensi yeso ilahlekelwa ukunwebeka futhi sinenkinga yokugxila ezintweni eziseduze, ukucindezeleka kwamehlo kungathinta noma ubani, kungakhathaliseki ubudala. Lokhu kwenzeka lapho imisipha ephethe ukugxila isebenza ngokungakhathali ukugcina amehlo egxile endaweni eseduze isikhathi eside.
Empeleni, ukucindezelwa kwamehlo noma i-asthenopia kuyisifo esibi kakhulu. ukuphazamiseka kokusebenza okuguqukayoKuvela lapho uhlelo lokubona lugcwele ngokweqile, kungaba ngokufunda izinhlamvu ezincane, ukushayela ezimweni ezinzima noma, ngokuvamile, ukusetshenziswa kakhulu kwamadivayisi edijithali akhipha ukukhanya okuluhlaza okwesibhakabhaka futhi aphoqa iso ukuba liqhubeke nomzamo wokusiza.
Izimpawu zesexwayiso: Ungazi kanjani ukuthi unenkinga yamehlo?
Izimpawu ziyahlukahluka kumuntu nomuntu, kodwa ezinye izimpawu cishe zivamile. Kuvamile kakhulu ukuzizwa ukuhlaba, ukulunywa, noma umuzwa wokucasuka Emehlweni ethu, kuzwakala sengathi besisesivunguvungwini sesihlabathi. Lokhu kuhambisana nokuklebhuka okuxakile noma ukoma okukhulu okusiphoqa ukuba sicwayize kakhulu kunokujwayelekile.
Kuvamile futhi ukuzwa ukubona okufiphele noma okukabiliikakhulukazi uma ususa amehlo akho esikrinini uye entweni ekude. Abantu abaningi babika ukuthi uphathwa yikhanda elibuhlungu elisesibukweni noma ubunzima emajwabu amehlo okwenza kube nzima ukugcina amehlo abo evulekile. Kwezinye izimo, kungase kuvele ukuvuvukala okuncane noma ukubomvu, okungase kuphazanyiswe kalula ngokuthi ukungezwani komzimba.
Izinto ezibangela ukucindezeleka kwamehlo
Imbangela enkulu, ngokungangabazeki, isikhathi eside sokubuka isikrini. I-Computer Vision Syndrome Lokhu kwenzeka ngoba, uma sigxila, asicwayizi kakhulu (sisuka cishe izikhathi ezingu-22 ngomzuzu siye ku-5 noma 13 kuphela), okuhwamukisa ifilimu yezinyembezi bese komisa i-cornea. Ngaphezu kwalokho, ukukhanya okuluhlaza okwesibhakabhaka okuvela kuma-monitor kungadala ukucindezeleka okwengeziwe kwi-retina.
Nokho, akukhona konke mayelana nobuchwepheshe. ukukhanya okunganeleKungakhathaliseki ukuthi kungenxa yokukhanya okweqile noma ukukhanya okunganele ngesikhathi ufunda, kuphoqa iso ukuthi lisebenze kanzima kabili. Ngalo mqondo, ukwamukela Ukukhanya kwe-OLED ehhovisi Kungasiza ekunciphiseni ukucindezeleka kwamehlo ngenxa yokuphathwa kwayo kokukhanya okuthuthukisiwe. Ezinye izici ezifana nokupholisa umoya, ukushisa okukhulu, intuthu kagwayi, noma ngisho nokucindezeleka kanye nokuntuleka kokulala kuthinta ngqo impilo yethu yokubona.
Futhi asinakukhohlwa amaphutha okubuyisa okungalungisiwe. Uma une- i-myopia, i-astigmatism, noma i-hyperopia Uma ukubona kungalungiswa kahle, uhlelo lwakho lokubona luzohlala luzabalaza ukugcina isithombe esicacile, okusheshisa ukuqala kokukhathala. Ngisho neminye imithi, njengemithi yokulwa namagciwane, ingomisa ubuso beso futhi yenze isimo sibe sibi kakhulu.
Amasu asebenzayo okunciphisa ukucindezeleka kwamehlo
Ukuze silwe nale nkinga, into elula kakhulu ukwenza izinguquko ezincane endleleni yethu yokusebenza. Igugu lomqhele yilona Umthetho we-20-20-20Njalo ngemizuzu engama-20, kufanele sibheke into eqhele ngamamitha ayi-6 (amamitha angama-20) okungenani imizuzwana engama-20. Lo msebenzi uvumela imisipha egxile ukuthi iphumule futhi iphule umjikelezo wokucindezeleka.
Ukulungiswa kwendawo yokusebenza kubalulekile. Isikrini kufanele sibekwe endaweni ephephile. ibanga eliphakathi kuka-50 no-70 cmIsikrini kufanele sibekwe ezingeni lamehlo noma ngaphansi kancane (cishe ama-degrees ayi-10-15) kanti ingxenye ephezulu yesikrini isezingeni lamehlo. Kunconywa ukusebenzisa izihlalo ezisebenza kahle ezisekelweni lomgogodla ukuvimbela ukucindezeleka kwentamo nomhlane ekubangeni ukukhathala okukhulu kwamehlo.
Ngokuphathelene nokukhanyisa, okuhle kakhulu ukubeka phambili ukukhanya kwemvelo kodwa ugweme... ukuzindla okuqondile esikrininiUma usebenza ngezibani ezikhanyayo kakhulu, zama ukuzifiphaza noma ukusebenzisa ukukhanya okungaqondile. Ukusebenzisa izihlungi ezilwa nokukhanya esibukweni sakho nokulungisa ukukhanya ukuze kufane nokukhanya okuzungezile kusiza ukuvimbela izinguquko ezisheshayo ezingafani.
Ukuze kulwiwe nokomisa, ukuphazima kweso Kuyithuluzi elingcono kakhulu, yize ukudabuka kokwenziwa kungaba usizo olukhulu ekugcineni i-cornea inamanzi, ikakhulukazi ezindaweni ezinomoya opholile. Kunconywa futhi ukuthi uthathe ikhefu ngokomzimba: vuka, welule, futhi uphuze amanzi ukuze ugcine umzimba wakho namehlo akho enamanzi.
Ukunakekelwa okukhethekile kanye nezixazululo zobungcweti
Uma imikhuba eyisisekelo inganele, sekuyisikhathi sokubonana nochwepheshe. Ukuhlolwa kwamehlo okuphelele kuyisinyathelo sokuqala sokuqeda isidingo sokuthola umuthi kadokotela. ukulungiswa okubonakalayo okubuyekeziweKunezibuko eziklanyelwe ngqo amakhompyutha ezivimba ukukhanya okuluhlaza okwesibhakabhaka futhi zithuthukise ibanga lokugxila, okwenza kube inketho ekhululekile kakhulu kunezingilazi zokuthintana kulabo abachitha amahora amaningi phambi kwe-PC, njengoba lezi zibuko zivame ukomisa amehlo kakhulu.
Kubashayeli, kuyalulekwa ukuthi bagweme ukushaywa umoya opholile ebusweni babo futhi basebenzise izibuko zelanga ezifanele ukunciphisa ukukhanya okukhanyayo. Endabeni yezingane, kubalulekile ukunciphisa isikhathi sokubuka isikrini nokukhuthaza imisebenzi yangaphandle ukuze kuncishiswe ukuqhubeka kwe-myopia nokuvimbela ukukhanya okuluhlaza okwesibhakabhaka ekuphazamiseni amaphethini azo okulala.
Ukudla ukudla okulinganiselayo, ukulala ngokwanele, nokuzijwayeza ukuzivocavoca kokuphumula kwamehlo, njengokushintsha ukugxila phakathi kwezinto eziseduze nezikude, kuqeda uhlelo oluqinile lwesenzo. Uma ubona ukuthi ukubona okufiphele kuyaqhubeka noma ikhanda liba lihlala likhona, vakashela udokotela wamehlo Kuyindlela ephephile yokuvimbela izinkinga zesikhathi eside.
Ukunakekela amehlo akho kuhilela ukuhlanganisa i-ergonomics efanele, ukuphumula njalo (ukulandela umthetho we-20-20-20), kanye nokuhlolwa kwamehlo kochwepheshe. Ngokulungisa ukukhanya, ukugcina amehlo akho enamanzi, kanye nokunciphisa ukusebenzisa kwakho amadivayisi edijithali, ungaqeda ukucindezeleka kwamehlo kanye nokungakhululeki, ubuyisele ukugxilisa ingqondo kanye nenhlalakahle iyonke.
