Likhalase tse khanyang tse putsoa li ka ba "icing on the cake" ho isa bohōleng bo itseng, empa ha lia lokela batho bohle.Ngaka e fana ka tlhahiso: "Batho ba nang le bothata ba retina kapa ba hlokang ho sebelisa lisebelisoa tsa elektronike ka matla ba ka 'na ba nahana ho roala likhalase tse putsoa. Leha ho le joalo, batsoali ha baa lokela ho khethalikhalase tse khanyang tse putsoabakeng sa bana feela ho thibela myopia."
1.likhalase tse khanyang tse putsoa ha li khone ho lieha ho qala ha myopia.
Batsoali ba bangata baa ipotsa: Na ba lokela ho khetha likhalase tse khanyang tse putsoa bakeng sa bana ba bona ba bonang haufi?Leseli la tlhaho le na le mebala e supileng e fapaneng ea khanya, 'me matla a eona a eketseha ka tatellano.Leseli le leputsoa le bonahalang mahlong a motho le bolela bolelele ba maqhubu a 400-500 nm.Leha e le leseli le leputsoa kaofela, bolelele ba maqhubu bo pakeng tsa 480-500 nm bo tsejoa e le khanya e putsoa ea maqhubu a malelele, 'me pakeng tsa 400-480 nm e bitsoa khanya e putsoa ea wave wave.Molao-motheo oa likhalase tse khanyang tse putsoa ke ho bonahatsa leseli le boputsoa ba maqhubu a makhutšoane ka ho roala lesela holim'a lense kapa ka ho kenyelletsa lintho tse bobebe tse boputsoa ka har'a lense ho monya "leseli le leputsoa," ho fihlela phello e putsoa.
Liteko li bontša hore ho sefa leseli le leputsoa ha ho kokobetse mokhathala oa mahlo o bakoang ke ho sheba li-skrini tsa k'homphieutha, leha e le hore ha ho na bopaki bo lekaneng ba ho paka hore e sebetsa hantle tabeng ea ho thibela myopia.
2.Kotsi ea leseli le leputsoa le hlahisoang ke li-skrini tsa elektroniki ho ea ho mahlo e lekanyelitsoe.
Le hoja leseli le leputsoa e se lona le matla ka ho fetisisa khanyeng e bonahalang, ke mohloli oa kotsi ka ho fetisisa.Lebaka ke hobane, le hoja khanya ea violet e na le matla a matla, batho ba batla ba le hlokolosi haholoanyane ka eona.Ka lehlakoreng le leng, leseli le leputsoa le fumaneha hohle mehleng ea digital mme le ke ke la qojoa.Lebone la mabone le li-skrini tsa elektroniki hangata le hlahisa leseli le lesoeu ka li-chips tse putsoa tse hlasimollang phosphor e mosehla.Ha skrini se khanya, 'mala o hlakile haholoanyane, khanya ea lebone le leputsoa le ea holimo.
Lebone la boputsoa ba maqhubu a makhutšoane le nang le matla a phahameng le na le monyetla o moholo oa ho hasana ha le kopana le likaroloana tse nyane moeeng, le bakang ho benya le ho etsa hore litšoantšo li shebahale ka pel'a retina, e leng se lebisang ho khelohe ha maikutlo a mebala.Ho pepesetsoa mabone a boputsoa ba maqhubu a makhutšoane haholo pele u robala ho ka sitisa tlhahiso ea melatonin, e leng se lebisang ho hlobaeleng.Liphuputso li bontša hore leseli le leputsoa la 400-450 nm le ka senya macula le retina.Leha ho le joalo, ho buisana ka kotsi ntle le ho nahana ka tekanyo ea litekanyetso ha hoa lokela;ka hona, lethal dose ea ho pepeseha ha leseli le leputsoa le bohlokoa.
3.Ha hoa nepahala ho nyatsa khanya eohle e putsoa.
Esita le khanya e putsoa ea maqhubu a khutšoanyane e na le melemo ea eona;liphuputso tse ling li fana ka maikutlo a hore khanya e putsoa ea maqhubu a makhutšoane khanyeng ea letsatsi e ka ntle e ka 'na ea e-ba le karolo ho thibela myopia ho bana, le hoja mochine o khethehileng o sa hlaka.Leseli le leputsoa la maqhubu a malelele le bohlokoa bakeng sa ho laola morethetho oa 'mele, ho ama hypothalamus synthesis ea melatonin le serotonin, ho susumetsa taolo ea boroko, ntlafatso ea maikutlo, le ntlafatso ea mohopolo.
Litsebi li hatisa: "Lense ea rona ka tlhaho e sefa leseli le leputsoa, ho e-na le ho khethalikhalase tse khanyang tse putsoa, senotlolo sa ho sireletsa mahlo a rōna ke tšebeliso e utloahalang.Laola nako le makhetlo a ho sebelisa lihlahisoa tsa elektroniki, boloka sebaka se loketseng nakong ea ts'ebeliso, 'me u netefatse mabone a kahare a kahare.Ho molemo ho etsa tlhahlobo ea mahlo khafetsa ho tseba le ho phekola mathata a mahlo ka nako."
likhalase tse khanyang tse putsoa, ka ho bonahatsa leseli le leputsoa le kotsi ka filimi e koahetsoeng holim'a lense kapa ho kenyelletsa lintlha tse khanyang tse sehiloeng ka boputsoa ka har'a lisebelisoa tsa lense, ho thibela karolo e kholo ea leseli le leputsoa, kahoo ho ka fokotsa tšenyo ea eona e tsoelang pele mahlong.
Ho feta moo, likhalase tse khanyang tse putsoa li ka ntlafatsa kutloisiso ea mahlo, tsa ntlafatsa ts'ebetso ea pono.Phuputso e entsoeng Chaena e bontšitse hore ka mor'a hore batho ba baholo ba roale lilense tse khanyang tse putsoa ka nakoana, kutloisiso ea bona ea ho bapisa libakeng tse fapaneng le tlas'a maemo a sa tšoaneng a khanya le mahlaseli a ntlafala.Ho bakuli ba nang le retinal photocoagulation ka lebaka la lefu la tsoekere la retinopathy,likhalase tse khanyang tse putsoae ka ntlafatsa boleng ba pono ea kamora ts'ebetso.Bakeng sa ba nang le lefu la mahlo a omileng, haholo-holo ba sebelisang lik'homphieutha kapa lisebelisoa tsa thelefono haholo, ho roala likhalase tse khanyang tse putsoa ho ka ntlafatsa pono e nepahetseng ka ho fetisisa le ho bapisa maikutlo ho ea ka mefuta e sa tšoaneng.
Ho latela pono ena, likhalase tse khanyang tse sehiloeng ka boputsoa ka sebele ke sesebelisoa se thusang ho sireletsa mahlo.
Ha re phethela,baetsi ba lense ea opticalba arabetse ka bokhabane keketsehong ea tlhokeho ea lilense tse putsoa, ba bonts'a boitlamo ba bona ho bophelo bo botle ba mahlo le boqapi ba mahlale.Ka ho kenyelletsa theknoloji e tsoetseng pele ea ho sefa mabone a boputsoa lihlahisoa tsa bona, bahlahisi bana ha ba rarolle feela matšoenyeho a bareki mabapi le khatello ea mahlo ea dijithale empa ba boetse ba beha litekanyetso tse ncha tsa liaparo tsa mahlo tse sireletsang.Nts'etsopele ena e totobatsa boitlamo ba indasteri ea optical ho ntlafatsa boiketlo ba pono le ho sireletsa pono lefats'eng la rona le ntseng le hola la dijithale.
