Kev tsis pom kev tsis pom kev ib ntus vim kev siv smartphone nquag tau kuaj pom thawj zaug hauv tus neeg mob Askiv peb xyoos dhau los. Tom qab ntawd, cov kws tshaj lij tau piav qhia tias cov cuab yeej siv tiag tiag tuaj yeem ua rau qhov muag tsis pom. Kev dai ntawm lub xov tooj yog fraught nrog rau lwm yam loj rau lub cev.

Dazzle nyob rau hauv ib lub qhov muag

Thaum lub caij ntuj no xyoo 2016, hauv tebchaws Askiv, ob tug poj niam ib zaug tau mus ntsib kws kho mob nrog kev tsis txaus siab ntawm lub sijhawm tsis pom kev. Cov neeg mob nyob hauv ntau qhov chaw ntawm lub tebchaws, tab sis lawv cov tsos mob zoo ib yam. Nyob rau hauv ob qho tib si, tsis pom kev tsuas yog poob rau hauv ib lub qhov muag thiab ntev li ntawm 15 feeb, tab sis qhov no tshwm sim yuav luag txhua hnub. Kev kuaj qhov muag, suav nrog kev kho qhov muag pom tomography, lub taub hau MRI, thiab kev kuaj ntshav rau qib vitamin A, tsis pom dab tsi. Nyob rau hauv txhua rooj plaub, cov neeg mob tau noj qab haus huv kiag li.

Nws muab tawm tias ob tus poj niam txhua hmo nyeem tau ntev los ntawm lub vijtsam smartphone, pw ntawm lawv sab hauv qhov tsaus ntuj. Hauv qhov no, ib lub qhov muag tau npog nrog lub hauv ncoo. Cov kws tshawb fawb ntawm City University of London, txaus siab rau cov xwm txheej no, qhia tias qhov ua rau qhov muag tsis pom kev yog kev hloov pauv lub teeb asymmetric. Hauv lwm lo lus, ib lub qhov muag hloov mus rau qhov kev hloov pauv sai ntawm qhov tsaus ntuj mus rau qhov kaj, thaum lwm qhov tsis ua.

Cov kev sim, thaum lub sijhawm cov neeg tuaj yeem pab dawb saib lub xov tooj smartphone nrog ib lub qhov muag ntev ntev, tau lees paub cov kws tshawb fawb kwv yees. Nws muab tawm tias qhov rhiab heev ntawm retina tsom ntawm lub xov tooj screen tau txo qis, thiab nws siv ob peb feeb kom rov zoo. Cov kws sau ntawv ntawm kev ua haujlwm tau sau tseg tias qhov muag tsis pom ib sab tsis yog qhov tsis zoo li nws yuav zoo li thaum xub thawj siab ib muag, thiab thaum siv lub smartphone nws yog qhov zoo dua los saib cov zaub nrog ob lub qhov muag.

Kev tuag ntawm cov hlwb

Raws li cov kws tshawb fawb los ntawm University of Toledo (Tebchaws USA), lub teeb xiav, ib txwm siv rau smartphones thiab khoos phis tawj, muaj kev cuam tshuam tsis zoo rau lub zeem muag. Nrog rau lub sijhawm ntev, nws yog ob peb zaug txaus ntshai rau lub retina dua li ntawm qhov pom spectrum.

Kev dai ntawm koj lub smartphone ntev ntev txhua hnub, tshwj xeeb tshaj yog nyob rau hauv qhov tsaus ntuj, tuaj yeem ua rau muaj hnub nyoog ntsig txog macular degeneration. Nrog rau tus kab mob no, ntau lab tus cones thiab rods tuag nyob rau hauv nruab nrab ntawm lub retina - lub macula. Thaum xub thawj, cov kab ncaj nraim pib tshwm wavy rau ib tus neeg, tom qab ntawd, thaum nyeem ntawv, qee cov ntawv ua tsis pom, thiab tom qab ntawd cov neeg mob tsis pom cov khoom uas lawv tab tom saib. Nyob rau tib lub sijhawm, peripheral tsis pom kev tuaj yeem khaws cia.

Lub teeb spectrum. Lub teeb xiav yog qhov txaus ntshai tshaj plaws rau tib neeg lub qhov muag

Complex chromophore proteins nyob rau hauv lub retina yog feem ntau yuav liam rau kev tuag ntawm cones thiab rods. Lawv txoj hauj lwm yog los pab cov photoreceptor hlwb paub lub teeb thiab xa cov teeb liab mus rau lub hlwb. Qee tus ntawm lawv (piv txwv li retinal A), thaum raug hluav taws xob xiav, ua rau cov ntaub so ntswg thiab cov hlwb nyob ib puag ncig. Thaum cov kws tshawb fawb hauv chav kuaj ua ke retinal A nrog ntau hom tib neeg lub hlwb, thiab tom qab ntawd ci xiav rau nws, nws tua cov hlwb. Thaum tsis muaj lub teeb xiav, cov proteins tsis muaj kev phom sij rau cov hlwb.

Ntxiv nrog rau cov cones thiab rods, macula muaj chromophore uas pab photoreceptor hlwb paub lub teeb thiab xa cov cim rau lub hlwb. Thaum raug lub teeb xiav, nws dhau los ua tshuaj lom rau cov hlwb nyob ib puag ncig

Horns nyob tom qab ntawm lub taub hau

Raws li ntau qhov haujlwm ntawm Australian cov kws tshawb fawb, smartphones txhawb kev loj hlob ntawm qee cov pob txha pob txha. Peb tab tom tham txog horn-shaped spines - pob txha loj hlob nyob rau sab nraum qab ntawm pob txha taub hau, tsim vim nquag tilting ntawm lub taub hau.

Qhov tseeb yog tias cov neeg feem coob, siv lub xov tooj smartphone, tsis yeem tig lawv lub taub hau rau pem hauv ntej - ze rau qhov screen. Qhov no hloov lub cev hnyav los ntawm tus txha nraub qaum mus rau cov leeg hauv qab ntawm lub taub hau. Yog li ntawd, cov pob txha pib loj hlob nyob rau hauv cov leeg thiab ligaments - ib tug horn-shaped pos. Feem ntau, nws yuav tsum tsis txhob ntau tshaj peb millimeters. Tab sis nyob rau hauv yuav luag 41 feem pua ntawm cov neeg tuaj yeem pab dawb hnub nyoog qis dua 30 xyoo (hauv tag nrho, 1200 tus neeg tau kuaj xyuas hauv txoj kev tshawb no, ntawm 300 tus neeg muaj hnub nyoog 18 txog 30), nws qhov loj yog los ntawm kaum mus rau 31 millimeters. Thiab feem ntau cov "horns" no tau pom nyob rau hauv cov txiv neej.

Yav dhau los, cov pob txha loj hlob zoo li no feem ntau yog cov neeg laus, uas tau koom nrog kev ua haujlwm hnyav rau lawv lub neej. Lawv feem ntau nrog mob taub hau thiab tsis xis nyob hauv caj dab thiab qaum. Cov pob txha zoo li lub pob txha pom hauv cov tub ntxhais hluas tuaj yeem pab dawb tsis ua rau lawv tsis xis nyob. Thiab nyob rau hauv cov hnub nyoog laus, cov pob txha loj hlob tsis tshua muaj ntau.

Cov kev tshawb fawb ntxiv tau pom tias horny spines yog qhov tshwm sim ntawm kev ntxhov siab ntau ntxiv ntawm cov leeg nqaij ntawm thaj chaw cervicocranial, thiab tsis yog kab mob caj ces lossis qhov tshwm sim ntawm kev raug mob yav dhau los. Muab lub hnub nyoog ntawm cov tswv ntawm horns, tib txoj kev uas lawv yuav tsum tau ntau zaus thiab ntev kom lawv lub taub hau me ntsis qaij rau pem hauv ntej yog siv smartphones, cov kws tshawb fawb qhia.

Mob hlwb

Raws li kev tshawb fawb los ntawm cov kws tshawb fawb ntawm Rutgers University (USA), smartphones muaj kev cuam tshuam tsis zoo rau lub hlwb. Yog tias koj siv sijhawm so ua haujlwm nrog lub xov tooj ntawm tes, koj lub hlwb yuav tsis so, thiab kev tsim khoom ntawm nws cov haujlwm ntxiv yuav tsuas yog phem dua.

Cov kws tshawb fawb tau nug 414 tus tub ntxhais kawm los daws 20 qhov teeb meem. Ob peb teev tau faib rau qhov no, lub sijhawm uas ib tus tuaj yeem siv sijhawm so. Lawv raug tso cai siv lawv lub sijhawm dawb nrog xov tooj, khoos phis tawj lossis phau ntawv sau. Koj tuaj yeem xaiv tawm ntawm qhov so.

Cov neeg ua haujlwm pab dawb uas tau so nrog smartphones hauv lawv txhais tes tau ua qhov phem tshaj plaws nrog kev ua haujlwm. Qhov nruab nrab, nws coj lawv 19 feem pua ntau dua los ua kom tiav cov haujlwm uas tsis ua tiav ua ntej so. Nyob rau tib lub sijhawm, lawv tau daws 20 feem pua tsawg dua qhov kev sib tw tsawg dua li cov neeg koom nrog kev kawm, thiab thaum kawg ntawm kev sim lawv xav tias nkees tshaj plaws.

Txawm li cas los xij, nws tseem ntxov dhau los tham txog kev vam khom ntawm smartphones (xws li tshuaj lossis kev ua si), cov kws tshawb fawb hais. Qhov no txhais tau hais tias qhov cuam tshuam tsis zoo ntawm gadgets ntawm lub cev tuaj yeem tswj tau. Qhov tseem ceeb tshaj plaws yog siv lawv kom zoo.
