Ngokunyuka kwemfuno yeeglasi, izitayile zezakhelo zikwahluka. Izakhelo zesikwere ezimnyama ezizinzileyo, iifreyimu ezingqukuva ezimibalabala ezibaxiweyo, izakhelo ezinkulu ezimenyezelayo ezinomphetho wegolide, kunye nazo zonke iintlobo zeemilo ezingaqhelekanga… Ke, kufuneka sihoye ntoni xa sikhetha izakhelo?
◀Malunga noBume beeglasi▶
Iifreyimu zemibukiso zidla ngokuqulunqwa ngesakhelo, ibhulorho yempumlo, iipads zempumlo, ii-endpieces, kunye neetempile, kunye neengcebiso zetempile, izikrufu, iihenjisi, njl.
●Isakhelo: Inkulu imilo yesakhelo, inkulu indawo ye-lens egciniweyo, kunye nobunzima obupheleleyo beeglasi buya kwanda. Ukuba umyalelo weeglasi uphezulu, ubukhulu be-lens buya kubonakala ngokucacileyo.
●Iintambo zempumlo: Izakhelo eziqhelekileyo zohlulwe zibe zintlobo ezimbini: iipads zempumlo ezihambayo kunye neepads zempumlo ezidibeneyo. Uninzi lwezakhelo zeplate ziyi-pads zempumlo ezidibeneyo, ezingenakulungelelaniswa. Oku akunabubele kakhulu kubahlobo ababhulorho yempumlo ayinamacala amathathu kakhulu, kwaye iya kutyibilika xa inxitywe. Isakhelo esineempumlo ezihambayo sinokufikelela kwinjongo yokulungelelanisa ngokulungisa iimpumlo zempumlo.
●Iitempile: Ubude beetempile bunquma ukuba iiglasi zakho zingaxhonywa ezindlebeni, ezidlala indima ekulinganiseni ubunzima. Ububanzi beetempile buya kuchaphazela induduzo yokunxiba ngokubanzi.
◀Malunga noHlobo lweSakhelo▶
01. Isakhelo seRim epheleleyo
Kubasebenzisi abanemigqaliselo ephezulu, impembelelo yokunxiba yeeglasi ezipheleleyo inokuthi ibonakale ngakumbi, kwaye umda wesakhelo uhle kakhulu. Ukongeza, imilo kunye nezixhobo zeefreyimu zembonakalo ziya kuba zizityebi kwaye zitshintshe, oko kukuthi, kuya kubakho izitayile ezininzi zeeglasi ezigcwele isakhelo kunezakhelo zembonakalo yezinye iintlobo zesakhelo, kwaye igumbi lokukhetha liya kwandisa kakhulu.
02. Isakhelo sesiqingatha-rim
Iiglasi ze-half-rim ubukhulu becala zilula ngokumila, zizinzile kwaye zinesisa. Iifreyimu zomboniso okwisiqingatha serim ubukhulu becala zenziwe nge-titanium esulungekileyo okanye i-B titanium, enobunzima obulula kwaye ikhululekile ukunxiba. Ubume besakhelo seeglasi zesiqingatha-zesondo ngokuqhelekileyo zixande okanye i-oval, eyona nto isetyenziswa kakhulu kwifreyimu yeglasi. Abaninzi abaqeqeshiweyo abanobuchule bathanda olu hlobo lwefreyimu yeglasi elula.
03. Isakhelo seRimless
Akukho phambi kwesakhelo, kuphela ibhulorho yempumlo yentsimbi, kunye neetempile zentsimbi. I-lens ixhunywe ngokuthe ngqo kwibhuloho yeempumlo kunye neetempileni ngezikrufu, kwaye imingxuma idla ngokugrunjwa kwi-lens. Iifreyimu ezingenafreyimu zikhaphukhaphu kwaye zinesitayile ngakumbi kunezakhelo eziqhelekileyo, kodwa amandla azo ngokubanzi angaphantsi kancinane kunezakhelo ezipheleleyo. Abantwana abakhuthazwa ukuba banxibe izakhelo ezinjalo. Ukudibanisa kwesakhelo esingenafreyimu kulula ukukhulula, ubude be-screw bukhawulelwe, kwaye akukhuthazwa ukusebenzisa olu hlobo lwesakhelo ukuba idigri iphezulu kakhulu.
◀Ukhetho Oluchasanayo Kwiimo Zobuso Ezahlukeneyo▶
01. Ubuso obungqukuva: ubude, isikwere, isakhelo sophondo lomqamelo
Abantu abanobuso obungqukuva banobuso obufutshane kwaye bajongeka bebahle, ngoko ke iifreyimu ze-angular kunye nezikwere zilungile ukulungisa imigca yobuso kunye nokongeza ubudlamko. Inokwandisa amandla kwaye ithintele ubuthathaka, yenza ubuso bubonakale bucacile kwaye bukhangele ngakumbi. Qaphela ukuba abantu abanobuso obungqukuva kufuneka bakuphephe ukukhetha iifreyimu ezingqukuva kakhulu okanye ezikwere kakhulu xa ukhetha izakhelo, kwaye abo banobuntu obukhulu kufuneka bakhethe ngononophelo.
02. Ubuso besikwere: isakhelo esingqukuva
Abantu abanobuso obusikwere banezidlele ezibanzi, ubuso obufutshane, kwaye babonakala beqinile. Ukukhetha isakhelo esigobe kancinci sinokwenza ubuso bubonakale buthambile kwaye lula izidlele ezibanzi kakhulu. Qaphela ukuba abantu abanobuso besikwere kufuneka bakhethe iiglasi ezinamafreyimu amancinci ngononophelo, kwaye iiglasi zesikwere kufuneka zigwenywe kangangoko kunokwenzeka.
03. Ubuso be-oval: iintlobo ezahlukeneyo zezakhelo
Ubuso obumbhoxo, obukwabizwa ngokuba bubuso obumbhoxo, bubuso obubizwa ngokuba bubuso obuqhelekileyo abantu basempumalanga. Kufanelekile ngakumbi ukugqoka zonke iintlobo zeefreyimu, qaphela nje ubungakanani besakhelo kufuneka bulingane nobukhulu bobuso kuyo. Kubuso be-oval, nikela ingqalelo nje ukuze ugweme ukukhetha isakhelo esimxinwa somgca othe tye.
◀Usikhetha njani isakhelo esikufanelayo▶
●Jonga kwifreyimu: Iiglasi ezingenasikhelo ziya kwenza abantu babonakale benobuchule; iiglasi zesiqingatha-square-frame zifanelekile ngakumbi kubantu abanzulu; iifreyimu ezingqukuva ziya kwandisa ubudlelwane babantu; iiglasi zefreyimu egcweleyo zisebenza ngeendlela ezininzi. Wonke umntu kufuneka ajonge ukuba zeziphi izihlandlo abadla ngokuzinxiba aze akhethe isakhelo esihambelanayo.
●Jonga iimpawu zobuso: Ukuba uneempawu zobuso ezibuthathaka kwaye ujongeka umncinci kwaye ulungile, ungakhetha ezinye iifreyimu ezibanzi, eziya kwandisa imbonakalo yakho yengqondo kwaye zenze iimpawu zobuso bakho zibonakale. Ngokuchasene noko, ukuba iimpawu zobuso bakho zinobubanzi obuthathu kwaye zithatha indawo enkulu yobuso bakho, khetha isakhelo esincinci, kuba ukukhetha isakhelo esibanzi kuya kukwenza ujongeke unamandla kwaye wonyuse ubunzima bentloko yakho.
●Jonga kwiinkundla zintathu: Sebenzisa irula ukulinganisa umgama phakathi kweenkundla zakho ezintathu, ezikumgama osuka kumgca woboya ukuya kumbindi wamashiya, ukusuka embindini wamashiya ukuya kwincam yempumlo, nokusuka kwincam yempumlo ukuya esilevini. Jonga umlinganiselo weatrium kwiinkundla ezintathu. Ukuba umlinganiselo we-atrium ude, khetha isakhelo esinobude obuphezulu, kwaye ukuba umlinganiselo we-atrium ufutshane, kufuneka ukhethe isakhelo esinobude obufutshane.
