Iyiphi ilensi yezinto ezibonakalayo engcono?

1.67 HMC
Izibuko kancane kancane ziye zaba yinto okufanele ibe nayo kubantu abaningi, kodwa abantu abaningi badidekile ngempela ngokukhetha ama-lens.Uma ukufanisa kungalungile, ngeke nje kuhluleke ukulungisa umbono, kodwa futhi kulimaza impilo yethu yamehlo, ngakho-ke indlela yokukhetha ilensi efanele lapho uthola izibuko?

 

(1) izacile futhi ilula

Izinkomba ezijwayelekile ze-refractive zamalensi e-CONVOX yilezi: 1.56, 1.59, 1.61, 1.67, 1.71, 1.74.Ngaphansi kwezinga elifanayo, ukuphakama kwenkomba ye-refractive yelensi, amandla okuguqula ukukhanya kwesigameko abe namandla, i-lens iba mncane futhi isisindo sibe nzima.Ilula futhi inethezekile ukugqoka.

(2) Ukucaca

Inkomba ye-refractive ayigcini nje ngokunquma ubukhulu be-lens, kodwa futhi ithinta inombolo ye-Abbe.Uma inombolo ye-Abbe inkulu, iyancipha ukuhlakazeka.Ngokuphambene, inombolo ye-Abbe encane, ukuhlakazeka okukhulu, futhi kubi nakakhulu ukucaca kwesithombe.Kodwa ngokujwayelekile, ukuphakama kwenkomba ye-refractive, ukuhlakazeka okukhulu, ngakho-ke ubuncane nokucaca kwelensi ngokuvamile akunakwa.

(3) Ukudlulisa ukukhanya

Ukudluliswa kokukhanya nakho kungenye yezinto ezithinta ikhwalithi yelensi.Uma ukukhanya kumnyama kakhulu, ukubuka izinto isikhathi eside kuzodala ukukhathala okubonakalayo, okungahambisani nempilo yamehlo.Izinto ezinhle zinganciphisa ngempumelelo ukulahleka kokukhanya, futhi umphumela wokudlulisa ukukhanya muhle, ucacile futhi usobala.Ukukunikeza umbono okhanyayo.

 (4) Ukuvikelwa kwe-UV

Ukukhanya kwe-Ultraviolet kungukukhanya okunobude begagasi obungu-10nm-380nm.Imisebe ye-ultraviolet eyeqile izodala umonakalo emzimbeni womuntu, ikakhulukazi emehlweni, futhi ibangele nokungaboni ezimeni ezinzima.Ngalesi sikhathi, umsebenzi we-anti-ultraviolet we-lens ubaluleke kakhulu.Ingavimba ngokuphumelelayo imisebe ye-ultraviolet ngaphandle kokuthinta ukudlula kokukhanya okubonakalayo, futhi ivikele amehlo ngaphandle kokuthinta umphumela wokubuka.
