Ilensi yokukhanya eluhlaza okwesibhakabhaka, ilensi edayiwe, i-lens etshintsha umbala, ilensi epolarized, ilensi yelanga...... Ilensi ekwimarike inezinto ezininzi, ezahlukeneyo, izinto kunye nomsebenzi ziyahluka, khetha ilensi elungele wena ukuvumela abantu abaninzi benze nzima. .Ingaba ezi lensi zinawuphi umsebenzi?Ngawaphi amaqela asebenza kuwo?Bafanele bakhethe njani abantwana nabafikisayo?
Ukukhanya okuluhlaza kunokuvuselela ukuphuhliswa kwamehlo.Akukhuthazwa ukuba unxibe iiglasi ezichasene neblue blue ixesha elide.Iiglasi ezichasene nombala oluhlaza okwesibhakabhaka zinokufunxa okanye zithintele ukukhanya okuluhlaza okwamaza amafutshane okubangela i-retinopathy, ukuze kuncitshiswe ukukhanya okuluhlaza kungena esweni kwaye kuthintele izifo zeretina ezibangelwa kukukhanya okuluhlaza.Kwakhona kunciphisa ukusasazeka, ukuvumela izinto ukuba zibonakale ngokucacileyo kwi-retina kunye nokunciphisa ubunzima bamehlo.
Kodwa iiglasi ezivalayo eziluhlaza zizodwa azinakuyithintela i-myopia, kwaye ukujonga isikrini ixesha elide nako kunokubangela ukudinwa.Ngaphezu koko, ukukhanya okuluhlaza okwesibhakabhaka kudlala indima ebalulekileyo kunye nelungileyo ekuphuhlisweni kwamehlo abantwana, kwaye umlinganiselo othile wokuvezwa kokukhanya okuluhlaza okwesibhakabhaka uyafuneka ukukhuthaza ukukhula kwabantwana kunye namehlo olutsha.
Akukhuthazwa ukuba abantwana kunye nabaselula banxibe iiglasi ezinemibala ngaphakathi.Zombini iiglasi eziguqula umbala kunye neeglasi ezinemibala zingabizwa ngokuba "ziiglasi zelanga ezinedigri," eziyimveliso eqhelekileyo yeeglasi ze-myopia.Kufuneka kuqatshelwe ukuba iilensi ezinamabala zinezinga elithile, ngoko ke iifreyimu ezinkulu kakhulu akufanele zikhethwe.Iifreyimu ezikhulu kakhulu aziyi kubangela kuphela imiphetho yelensi engqindilili kunye nebala elingalinganiyo, kodwa zibangela ukungakhululeki kulowo uyinxibileyo.
Ngaphezu koko, iilensi ezinemibala zinokunciphisa inani elipheleleyo lokukhanya okungena iliso, okuchaphazela ukuhanjiswa kwelensi.I-lens imnyama, izinto zangaphandle zimnyama.Ngoko ke, kungcono ukuba ungagqoki iiglasi ezigqwebileyo ngaphakathi, kwaye kuyimfuneko ukukhetha iilensi ezimnyama zokugqoka ngaphandle.
Iilensi zokutshintsha umbala zifanelekile ngakumbi kubantu abaneedigri ezisezantsi kwaye akukho mahluko kakhulu phakathi kwamehlo amabini.Uninzi lweelensi zokutshintsha umbala zixhomekeke kubukhulu bokukhanya kwe-ultraviolet ukulamla inkqubo yokutshintsha umbala.Ngaphandle, iilensi zilungelelanisa ngokuzenzekelayo kwiinguqu ze-uv, ukusuka kwiilensi ezicacileyo ngokukhawuleza ukuya kwiilensi ezimnyama;Ngaphakathi, ubunzulu bemitha ye-uv buyancipha kwaye iilensi zibuyela ebumnyameni ukuya ekukhanyeni.Ukuba iqondo le-myopia likhulu kakhulu, i-lens ibhityile embindini, ingqindilili emphethweni, ikhanya embindini kwaye imnyama ijikeleze umbala.Umahluko wedigri yamehlo amabini mkhulu kakhulu, malunga namaqhekeza amabini obunzulu bombala nawo anokwahluka, achaphazele ubuhle.Ukongezelela, iiglasi zokutshintsha umbala ezisetyenziselwa ixesha elide, umbala ongasemva uya kubonakala ngakumbi, uchaphazela ukubonakala, ngoko kufuneka utshintshwe rhoqo kwiminyaka emibini.
Iiglasi ze-polarized kunye nezibuko zelanga zifanelekile kwimisebenzi yangaphandle efana nokuqhuba, ukuloba kunye ne-skiing.I-lens ye-polarizing yongeza umaleko wokucoca i-polarizing, inokucoca ukukhanya okuqaqambileyo okubonakalayo kunye nokukhanya okuthe saa, inomsebenzi wokunciphisa ilitha, inokunciphisa ukukhanya okunamandla, yenza intsimi yombono icace ngakumbi.Iglasi yelanga iliso "i-sunscreen", inokufunxa okanye ihlaziye ukukhanya okuninzi, inciphise ukukhanya okungena iliso, inciphise ukuziva ungonwabi kweso, eyona mpembelelo ibalulekileyo kukuthintela imisebe ye-ultraviolet, ukunceda iliso linciphise. ukwenzeka kwesifo.
