Enye yezona zinto zixhaphakileyo ngonyango lokukhanya okubomvu yindawo yamehlo.Abantu bafuna ukusebenzisa izibane ezibomvu eluswini lobuso, kodwa banexhala lokuba ukukhanya okubomvu okuqaqambileyo okulathwe apho kusenokungabi yeyona nto ilungileyo emehlweni abo.Ngaba ikho into omele ukhathazeke ngayo?Ngaba ukukhanya okubomvu kuwonakalisa amehlo?okanye ngaba eneneni inokuba luncedo kakhulu kwaye incede ukuphilisa amehlo ethu?
Intshayelelo
Amehlo mhlawumbi ngawona malungu abuthathaka naxabisekileyo emizimbeni yethu.Umbono obonakalayo yinxalenye ephambili yamava ethu okuqonda, kwaye into ebaluleke kakhulu ekusebenzeni kwethu kwemihla ngemihla.Amehlo omntu anomdla ngakumbi ekukhanyeni, akwazi ukwahlula phakathi kwemibala efikelela kwizigidi ezili-10.Bayakwazi ukubona ukukhanya phakathi kobude be-400nm kunye ne-700nm.
Asinayo i-hardware yokubona kufuphi nokukhanya kwe-infrared (njengoko isetyenziswe kunyango lwe-infrared light therapy), njengokuba singaboni ezinye ii-wavelengths zemitha ye-EM efana ne-UV, i-Microwaves, njl. ifoton enye.Njengakwezinye iindawo emzimbeni, amehlo ayilwe ziiseli, iiseli ezikhethekileyo, zonke zenza imisebenzi ekhethekileyo.Sineeseli zentonga zokubona ukukhanya kokukhanya, iiseli ze-cone zokubona umbala, iiseli ezahlukeneyo ze-epithelial, iiseli ezivelisa uburharha, iiseli ezivelisa i-collagen, njl njl. Ezinye zezi seli (kunye nezicubu) zisengozini kwezinye iintlobo zokukhanya.Zonke iiseli zifumana izibonelelo kwezinye iintlobo zokukhanya.Uphando kule ndawo luye lwanda kakhulu kwiminyaka eyi-10 edlulileyo.
Ngowuphi uMbala/Ubude bokukhanya okuLungileyo emehlweni?
Uninzi lwezifundo ezibonisa imiphumo enenzuzo zisebenzisa ii-LED njengomthombo wokukhanya kunye nobuninzi obujikeleze ubude be-670nm (obomvu).I-Wavelength kunye nohlobo lokukhanya / umthombo ayizona kuphela izinto ezibalulekileyo nangona, njengoko ukukhanya kokukhanya kunye nexesha lokuvezwa lichaphazela iziphumo.
Isibane esibomvu sinceda njani amehlo?
Njengoko amehlo ethu esona sicatshulwa sibalulekileyo sokukhanya emzimbeni wethu, umntu unokucinga ukuba ukufunxwa kokukhanya okubomvu ngamacones ethu abomvu kunento yokwenza neziphumo ezibonwe kuphando.Oku akunjalo ngokupheleleyo.
Ithiyori ephambili echaza iziphumo zonyango olubomvu kunye nolusondeleyo lwe-infrared, naphi na emzimbeni, lubandakanya intsebenziswano phakathi kokukhanya kunye ne-mitochondria.Umsebenzi ophambili we-mitochondria kukuvelisa amandla kwiseli yayo -unyango olulula luphucula amandla ayo okwenza amandla.
Amehlo abantu, kwaye ngokukodwa iiseli ze-retina, zineemfuno eziphezulu ze-metabolic zazo naziphi na izihlunu kuwo wonke umzimba - zifuna amandla amaninzi.Ekuphela kwendlela yokuhlangabezana nale mfuno iphezulu kukuba iiseli zigcine ii-mitochondria ezininzi - kwaye ke akumangalisi ukuba iiseli zamehlo zineyona mitochondria ephezulu naphi na emzimbeni.
Ukubona njengoko unyango olulula lusebenza ngokunxibelelana ne-mitochondria, kwaye amehlo anowona mthombo utyebileyo we-mitochondria emzimbeni, yingcinga efanelekileyo yokucinga ukuba ukukhanya kuya kuba neziphumo ezinzulu emehlweni xa kuthelekiswa nezinye iindawo. umzimba.Ngaphezulu koko, uphando lwakutsha nje lubonise ukuba ukuwohloka kwamehlo kunye ne-retina kunxulumene ngokuthe ngqo nokungasebenzi kakuhle kwe-mitochondrial.Ke unyango olunokuthi lubuyisele i-mitochondria, apho zininzi, kwiliso yindlela efanelekileyo.
Ubude obungcono bokukhanya
Ukukhanya kwe-670nm, uhlobo olubomvu olubonakalayo lokukhanya, yeyona nto ifundwayo kuzo zonke iimeko zamehlo.Amanye amaza aneziphumo ezilungileyo abandakanya i-630nm, 780nm, 810nm & 830nm. I-Laser vs. LEDs - inqaku Ukukhanya okubomvu ukusuka nokuba yi-laser okanye ii-LEDs zingasetyenziswa naphi na emzimbeni, nangona kukho enye ngaphandle kwee-lasers ngokukodwa - amehlo.IiLaser AKUFANELEKANGA kunyango olulula lwamehlo.
Oku kungenxa yepropathi ehambelanayo / ehambelanayo ye-beam yokukhanya kwe-laser, enokuthi igxininiswe yi-lens yeso ukuya kwindawo encinci.Wonke umqa wokukhanya kwelaser unokungena esweni kwaye onke loo mandla agxininiswe kwindawo encinci ebukhali kwi-retina, enika uxinano lwamandla agqithileyo, kwaye inokutshisa / yonakalise emva kwemizuzwana nje embalwa.Iiprojekthi zokukhanya kwe-LED ngaphandle kwi-engile kwaye ke ayinayo lo mba.
Ukuxinana kwamandla kunye nethamo
Ukukhanya okubomvu kudlula iliso kunosulelo olungaphezulu kwe-95%.Oku kuyinyaniso ekukhanyeni okukufutshane kwe-infrared kunye nokufana nokunye ukukhanya okubonakalayo okuluhlaza okwesibhakabhaka / eluhlaza / emthubi.Ukunikezelwa koku kungena okuphezulu kokukhanya okubomvu, amehlo afuna kuphela indlela yonyango efanayo kwesikhumba.Izifundo zisebenzisa malunga ne-50mW/cm2 uxinano lwamandla, kunye needosi eziphantsi kakhulu ze-10J/cm2 okanye ngaphantsi.Ngolwazi oluthe kratya malunga nedosi yonyango olukhanyayo, bona le post.
Ukukhanya okuyingozi kwamehlo
Ubude obuluhlaza, obuluhlaza kunye nokukhanya kwe-UV (200nm-480nm) akulunganga emehlweni, idityaniswe nokuba kumonakalo we-retinal okanye umonakalo kwi-cornea, ukuhlekisa, i-lens kunye ne-nerve optical.Oku kubandakanya ukukhanya okuluhlaza okwesibhakabhaka, kodwa kunye nokukhanya okuluhlaza njengenxalenye yezibane ezimhlophe ezifana neebhalbhu ze-LED zasekhaya / zesitalato okanye izikrini zekhompyutha / zefowuni.Izibane ezimhlophe ezikhanyayo, ngakumbi ezo ezinokushisa kombala ophezulu (3000k +), zinepesenti enkulu yokukhanya okuluhlaza okwesibhakabhaka kwaye azikho sempilweni emehlweni.Ukukhanya kwelanga, ngakumbi ilanga lasemini elibonakaliswa emanzini, likwaqulethe ipesenti ephezulu yeblue, ekhokelela kumonakalo wamehlo ekuhambeni kwexesha.Ngethamsanqa iatmosfera yomhlaba iyahluza (isasaze) ukukhanya okuluhlaza ukusa kumlinganiselo othile – inkqubo ebizwa ngokuba ‘yirayleigh scattering’ – kodwa ukukhanya kwelanga kwasemini kusekuninzi, njengoko kwenza ukukhanya esibhakabhakeni okubonwa ngoosomajukujuku.Amanzi afunxa ukukhanya okubomvu ngakumbi kunokukhanya okuluhlaza okwesibhakabhaka, ngoko ke ukukhanya kwelanga kumachibi/elwandle/ njalo njalo kungumthombo oluhlaza oluhlaza.Ayibonakali nje ukukhanya kwelanga okunokwenza ingozi nangona 'iliso le-surfer' ingumba oqhelekileyo onxulumene nomonakalo wamehlo okukhanya kwe-UV.Abahambi, abazingeli kunye nabanye abantu bangaphandle banokuphuhlisa oku.Oomatiloshe bemveli abafana namagosa omkhosi wamanzi amadala kunye nabaphangi badla ngokusoloko bephuhlisa imiba yokubona emva kweminyaka embalwa, ikakhulu ngenxa yemitha yelanga yolwandle, eyenziwa mandundu yimiba yesondlo.Ubude obukude be-infrared (kunye nobushushu nje ngokubanzi) bunokuba yingozi emehlweni, njengakwezinye iiseli zomzimba, ukonakala kokusebenza kwenzeka xa iiseli zifudumala kakhulu (46°C+/115°F+).Abasebenzi bemisebenzi emidala enxulumene neziko elifana nolawulo lwe-injini kunye nokuvuthela kweglasi bahlala bephuhlisa imiba yamehlo (njengoko ubushushu obuphuma kwimililo/kwiiziko bude nge-infrared).Ukukhanya kweLaser kunokuba yingozi emehlweni, njengoko kukhankanyiwe ngasentla.Into efana ne-laser eluhlaza okwesibhakabhaka okanye ye-UV inokuba yeyona iyonakalisayo, kodwa eziluhlaza, ezityheli, ezibomvu kunye ne-infrared lasers zisenokubangela ingozi.
Iimeko zamehlo zanceda
Umbono jikelele - ukubona, i-Cataracts, i-Diabetic Retinopathy, i-Macular Degeneration - i-aka AMD okanye i-macular degeration enxulumene neminyaka, i-Refractive Errors, i-Glaucoma, i-Dry Eye, i-floaters.
Ukusetyenziswa okusebenzayo
Ukusebenzisa unyango olukhanyayo emehlweni phambi kokuba ube sesichengeni selanga (okanye ukuvezwa kukukhanya okumhlophe okuqaqambileyo).Ukusetyenziswa kwemihla ngemihla / ngeveki ukuthintela ukuwohloka kwamehlo.
