Ngaba kuyimfuneko "Ukutshintsha iiglasi zelanga rhoqo emva kweminyaka emi-2"?

Ubusika bufikile, kodwa ilanga lisakhanya ngokuqaqambileyo. Njengoko ulwazi lwezempilo lomntu wonke lusanda, baya besanda abantu abanxiba iindondo zelanga xa bephuma. Kubahlobo abaninzi, izizathu zokutshintsha iindondo zelanga ubukhulu becala kungenxa yokuba zaphukile, zilahlekile, okanye azikho sefashonini ngokwaneleyo… Kodwa enyanisweni, kukho esinye isizathu esibalulekileyo esisoloko singahoywa ngumntu wonke, kwaye eso sesokuba iindondo zelanga “ziyaphelelwa ngenxa yokwaluphala.”

Kutshanje, ngokufuthi sibona amanqaku athile esikhumbuza ukuba “iiglasi zelanga ziphila iminyaka emibini kuphela yaye kufuneka zitshintshwe emva kwelo xesha.” Ke, ngaba ubomi beendondo zelanga yiminyaka emibini kuphela?

Iiglasi zelanga ngokwenene "ziyaguga"

Izinto ezisisiseko zelensi yelanga ngokwayo zinokufunxa imitha yeultraviolet, kwaye ukugquma kweelensi zelanga kunokubonakalisa eminye yemitha yeultraviolet. Iilensi ezininzi zelanga nazo zinezixhobo zokufunxa i-UV ezongeziweyo kuzo. Ngaloo ndlela, ininzi yemitha ye-ultraviolet "inokugcinwa ngaphandle" kwaye ayikwazi ukulimaza amehlo ethu.

Kodwa olu khuselo alukho ngokusisigxina.

Ngenxa yokuba imitha ye-ultraviolet ithwala amandla aphezulu, iya kuguga izixhobo zeglasi zelanga kwaye inciphise amandla ezithako zelanga zokufunxa imitha ye-ultraviolet. Utyatyazo olumenyezelayo olungaphandle kweendondo zelanga luyisiphumo sokubekwa komphunga wesinyithi, kwaye ezi zogquma zinokunxiba, zikhuphe ioksijini, kwaye zinciphise amandla azo okubonakalisa. Oku kuya kunciphisa isakhono sokukhusela i-UV seendondo zelanga.

Ukongezelela, ukuba asiyikunyamekela izibuko zethu zelanga, kuya kudla ngokubangela ukunxiba ngokuthe ngqo iilensi, ukukhulula iitempile, ukuguqulwa, kunye nokulimala kwesakhelo kunye neempumlo zempumlo, njl., Okuya kuchaphazela ukusetyenziswa okuqhelekileyo kunye nokukhusela i-sunglasses.

Ngaba kuyimfuneko ngokwenene ukuyitshintsha rhoqo emva kweminyaka emibini?

Okokuqala, ndifuna ukuchaza ukuba oku akusiyo i-rumor, kodwa olu phando lukhona ngokwenene.

Unjingalwazi uLiliane Ventura kunye neqela lakhe leDyunivesithi yaseSao Paulo eBrazil benze uphando oluninzi kwiindondo zelanga. Kwelinye lamaphepha abo, bakhankanye ukuba bacebisa ukutshintsha iiglasi zelanga rhoqo emva kweminyaka emibini. Esi sigqibo siye sacatshulwa ngamajelo eendaba amaninzi, kwaye ngoku sihlala sibona umxholo ofanayo waseTshayina.

Kodwa esi sigqibo sinesiseko, oko kukuthi, abaphandi babalwe ngokusekwe kukuqina kokusebenza kweendondo zelanga eBrazil… oko kukuthi, ukuba unxiba iiglasi zelanga iiyure ezi-2 ngosuku, amandla okukhusela e-UV eeglasi zelanga aya kuncipha emva kweminyaka emibini. , kufuneka itshintshwe.

Masiyive. EBrazil, ukukhanya kwelanga kunje kwiindawo ezininzi… Ngapha koko, lilizwe elizithandayo laseMzantsi Melika, kwaye ngaphezu kwesiqingatha selizwe likwiitropiki…

Ngoko kulo mbono, abantu abasenyakatho yelizwe lam akunakwenzeka ukuba banxibe izibuko zelanga ze-2 iiyure ngosuku. Ngoko ke, sinokugcina imali ethile. Ngokuxhomekeke kubuninzi bokunxiba, akukho ngxaki ukuyinxiba unyaka omnye okanye emibini ngaphezulu kwaye uyitshintshe. Iingcebiso ezinikwe ngabavelisi beglasi belanga abaziwayo okanye abavelisi bezibuko zelanga bezemidlalo ubukhulu becala baxhomekeke kubuninzi bokusetyenziswa, kwaye kufuneka zitshintshwe rhoqo emva kweminyaka emi-2 ukuya kwemi-3.

Oku kuya kwenza ukuba iiglasi zakho zelanga zihlale ixesha elide

Iperi yeendondo zelanga eziqeqeshiweyo isoloko ingabizi mali iphantsi. Ukuba siyinyamekela kakuhle, inokusikhusela ixesha elide. Ngokukodwa, sifuna kuphela:

• Yigcine ngexesha xa ingasetyenziswa ukunqanda ukuguga okanye ukukhanya kwelanga.
• Bahlobo abaqhubayo, ncedani ningashiyi izibuko zelanga kwicentre console ukuze nizibeke elangeni.
• Xa ubeka iiglasi zelanga okwexeshana, khumbula ukujongisa iilensi phezulu ukunqanda ukunxiba.
• Sebenzisa ikesi yeglasi okanye isingxobo, njengoko ezi zikhongozeli zikhethekileyo zinendawo yangaphakathi ethambileyo engasayi konakalisa iilensi zakho.
• Musa ukufaka nje iiglasi zakho zelanga epokothweni yakho, okanye uziphose kubhaka wakho kwaye uzihlikihle kwezinye izitshixo, izipaji, iiselfowuni, njalo njalo, njengoko oku kunokonakalisa ngokulula ukugquma kweeglasi. Isenokutyumza ngqo isakhelo.
• Xa ucoca iiglasi zelanga, ungasebenzisa isepha, isepha yesandla kunye nezinye izinto zokucoca ukwenza amagwebu ukucoca iilensi. Emva kokuhlamba, sebenzisa i-lens yokucoca ilaphu ukuze uyomise, okanye usebenzise ngokuthe ngqo iphepha elikhethekileyo le-lens elimanzi. Xa kuthelekiswa "nokosula okomileyo", oku kulula ngakumbi. Ayifane yenzeke imikrwelo.
• Nxiba izibuko zakho zelanga ngokuchanekileyo kwaye ungazibeki phezulu ngaphezulu kwentloko yakho, njengoko zinokophuka ngokulula okanye zophuke, kwaye iitempile zinokwaphuka.

Gcina nje ezi ngqondweni xa ukhetha iiglasi zelanga

Enyanisweni, akunzima konke konke ukukhetha izibuko zelanga ezifanelekileyo. Kufuneka ukhangele kuphela iiglasi zelanga ezinophawu oluthi “UV400” okanye “UV100%” kwivenkile eqhelekileyo Ezi logo zimbini zibonisa ukuba iiglasi zelanga zinokufikelela phantse i-100% yokhuseleko kwimitha yeultraviolet.Kwanele ukuba nefuthe lokukhusela.

Indlela yokukhetha umbala? Ngokuqhelekileyo, ukusetyenziswa kwansuku zonke, sinokubeka phambili kwiilensi ezimdaka kunye negrey, kuba zinempembelelo encinci kumbala wezinto, zilungele ukusetyenziswa kwansuku zonke, ngokukodwa ukuqhuba, kwaye aziyi kuchaphazela ukuqwalaselwa komqhubi wezibane zendlela. Ukongeza, abahlobo abaqhubayo banokukhetha iiglasi zelanga ezineelensi zepolarized ukunciphisa ilitha kwaye baqhube kakuhle.

Xa ukhetha iindondo zelanga, kukho inkalo enye engayihoywa lula, kwaye leyo “yimilo.” Kulula ukucinga ukuba izibuko zelanga ezinommandla omkhulu kunye ne-curvature ehambelana nesimo sobuso zinefuthe elihle lokukhusela ilanga.

Ukuba ubungakanani bezibuko zelanga abufanelekanga, i-curvature ayihambelani nemilo yobuso bethu, okanye iilensi zincinci kakhulu, nokuba iilensi zinokhuseleko olwaneleyo lwe-UV, ziya kuhlala zivuza ukukhanya kuyo yonke indawo, zinciphisa kakhulu umphumo wokukhusela ilanga.

Sihlala sibona amanqaku athi ukusebenzisa isibane se-banknote detector + ii-banknotes kunokugqiba ukuba izibuko zelanga zithembekile okanye akunjalo. Ngenxa yokuba iiglasi zelanga zinokukhusela kwimitha ye-ultraviolet, isibane sesixhobo sokujonga imali asikwazi ukukhanyisa uphawu oluchasene ne-counterfeiting ngezibuko zelanga.

Le nkcazo eneneni ivulekele umbuzo kuba ihambelana namandla kunye nobude besibane somtshini wemali. Izibane ezininzi zokujonga imali zinamandla aphantsi kakhulu kunye nobude obusisigxina. Ezinye iiglasi eziqhelekileyo zinokuvala imitha ye-ultraviolet ekhutshwa zizibane ze-banknote detector, ukuthintela amanqaku e-banknote anti-counterfeiting ukuba akhanyise. Ke ngoko, kukhuselekile ukusebenzisa izixhobo zobuchwephesha ukugweba amandla okukhusela ezibuko zelanga. Kuthi thina bathengi abaqhelekileyo, kubaluleke kakhulu ukujonga i-"UV400" kunye ne "UV100%".

Okokugqibela, ukushwankathela, iiglasi zelanga zinegama elithi “ukuphelelwa lixesha kunye nokuwohloka”, kodwa akukho mfuneko yokuba sizitshintshe qho emva kweminyaka emibini.

Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
