Ngenxa yokukhanya kwelanga ehlotyeni, ngaba kukwenza ungakwazi ukuvula amehlo akho?Uninzi lwabantu lungathanda ukunxiba ipere enkuluiindondo zelangaxa uqhuba okanye uphuma ukuthintela ilitha lelanga.Kodwa, ngaba ukhethe izibuko zelanga ezifanelekileyo?Ukuba ukhetha iindondo zelanga ezingafanelekanga, aziyi kuwakhusela amehlo akho, zide “zimfamekise amehlo” zize zibangele iingozi zendlela kwiimeko ezimandundu.Kubonakala ngathi ngumbuzo olula ukukhetha izibuko zelanga ezifanelekileyo, kodwa kukho ukungaqondi kakuhle okuninzi.
Okulandelayo, ndingathanda ukwazisa ukungaqondi kakuhle xa ukhetha iindondo zelanga:
Intsomi 1: Umbala omnyama, ungcono
Abantu abaninzi bayithatha nje kancinci into yokuba okukhona mnyama umbala welensi, kokukhona ukhuseleko lwe-UV lungcono.Enyanisweni, umsebenzi weiindondo zelangaukucoca imisebe ye-ultraviolet inxulumene kuphela nefilimu yokwambathisa, kwaye umbala awukho mnyama ngokusemandleni.Ngokukodwa kubaqhubi abahamba umgama omde, ukuba izibuko zelanga zimnyama kakhulu, amehlo athanda ukudinwa, kwaye kuyingozi ngakumbi ukungena kwiitonela nakwezinye iindawo ezinokukhanya okuthe gqolo okumfiliba okuvela kwilanga elinamandla.
Intsomi yesi-2: Iilensi zepolarized zezona zifanelekileyo
Abaqhubi abaninzi bathanda ukunxibaiiglasi ezipholileyo.Ngokwenene, iiglasi ezipholileyo zinokunciphisa ukukhanya okunamandla, ziphelise ilitha, kwaye zenze umgca wokubona ube wendalo kwaye uthambe.Ngapha koko, iiglasi zepolarized zifaneleke ngakumbi ukuloba, ukutyibiliza kunye nezinye iindawo ezibonisa indawo enkulu kodwa hayi kuzo zonke izihlandlo.Umzekelo, umqhubi ngamanye amaxesha kufuneka ajongane nemeko emnyama njengakwitonela, ngelixa i-lens yepolarized kulula ukwenza amehlo ngequbuliso ebumnyameni okuyingozi kumqhubi.Ukongeza, i-lens ye-polarized iya kukhanyisa umbala wezikrini ze-LCD kunye nezibane ze-LED.Ke ngoko, ngaphambi kokukhetha izibuko zelanga, kuya kufuneka uqwalasele eyona nto iphambili oya kubandakanyeka kuyo kunye ne-sunshades.Iindondo zelanga ezingapholiyo zisenokufaneleka ngakumbi kuwe.
Intsomi yesi-3: Musa ukunxiba iindondo ze-myopia
Abanye abaqhubi bane-myopic encinci, kwaye akukho ngxaki ukuqhuba ngaphandle kweeglasi ze-myopic ngamaxesha aqhelekileyo.Kodwa xa sele unxibeiindondo zelanga, ingxaki ifika: amehlo akho atyekele ngakumbi ekudinweni, yaye ukubona kwakho kuya kuhla, kanye njengokuba umbono wakho uya kuchaphazeleka xa uqhuba ebusuku.Ke ngoko, abaqhubi abane-myopia ethambileyo banokuqhuba ngaphandle kwengxaki.Ukuba bafuna ukunxiba iindondo zelanga, kufuneka baxhotyiswe ngeelensi ezinemyopia degree.
Intsomi yesi4: Umbala weendondo zelanga umhle kakhulu
Ulutsha olunefashoni luya kuba neendondo zelanga ezinemibala eyahlukahlukeneyo.Liyinyaniso elokuba zikhangeleka kakuhle, kodwa azifanele zisetyenziswe xa uqhuba.Ngokomzekelo, iilensi ezipinki kunye nemfusa ziya kutshintsha umbala kunye ne-spectrum.Enyanisweni, kungcono ukusebenzisa iilensi ezimpunga kwiiglasi zelanga, kuba aziyi kutshintsha umbala osisiseko.Okulandelayo kuluhlaza bumnyama.Iilensi eziBrown kunye nephuzi zinokuphucula ukukhanya kwaye zifaneleke ngakumbi kwiindawo ezinenkungu kunye nothuli.
Xa uqhuba ehlotyeni, kufuneka ukhethe ngokufanelekileyoiindondo zelangangokwemeko yakho yokwenyani ukuthintela iingozi zokuqhuba.
