Abathengi abaningi badidekile lapho bethenga izibuko zamehlo. Imvamisa bakhetha ozimele ngokuya ngezinto abazithandayo, futhi ngokuvamile babheka ukuthi ozimele banethezekile yini nokuthi intengo inengqondo yini. Kepha ukukhetha kwamalensi kuyadida: Yimuphi umkhiqizo omuhle? Yimuphi umsebenzi welensi efanelekile? Yimaphi ama-lens angekhwalithi ephezulu? Lapho ubhekene nezinhlobonhlobo zamalensi, ukhetha kanjani lowo ofanele?
Ngabe abasebenzi basehhovisi bakhetha kanjani?
Abasebenzi basehhovisi bavame ukudinga ukubhekana nekhompyutha isikhathi eside, baphinde bashintshe futhi bephuma phakathi kwemikhiqizo ehlukahlukene ye-elekthronikhi. Kulula ukudala amandla ngokweqile, kwandisa ukukhathala okubonakalayo. Ngokuhamba kwesikhathi, ukomisa kwamehlo, i-astringency yamehlo, umbono ofiphele nezinye izimpawu kuye kwavela, kuthinta ukusebenza kahle komsebenzi futhi kuthambekele ezinhlungwini zemiphumela ehlukahlukene, ikhanda, ikhanda, amehlo owomile nokunye.
Ngakho-ke, kubasebenzi basehhovisi abasebenza amahora amaningi ngemikhiqizo ye-elekthronikhi, amalensi abo kufanele abe nomsebenzi wokukhathala okulwa nokukhanyisa okulimazayo nokuvikela ukukhanya okuluhlaza okwesibhakabhaka nokuvikela impilo yamehlo.
Imikhiqizo efanelekile yilensi yemibala egcwele imibala ye-PhotoChromic, kanye nama-Photochromic we-PhotoChromic angu-Anti-Blue Light.
Bakhetha Kanjani Abafundi?
Njengoba abafundi bangaphansi kwengcindezi enkulu yokufunda, indlela yokunciphisa ijubane futhi balawule ukukhula kwe-myopia kuhlale kuyikhathalela kakhulu abafundi nabazali babo. Izimbangela ze-Myopia ezinganeni nasentsha zihlukile, ngakho-ke ngaphambi kokuthola umuthi, kufanele uqale uhlole ukuhlolwa kwe-optometric, bese ukhetha umkhiqizo ohlangabezana nezidingo zakho ngokuya ngemiphumela yokuhlolwa kanye nesimo samehlo akho , ukuzembezele ngempumelelo ukuthuthukiswa kwe-Myopia.
Kubafundi abanengcindezi ekhulayo yokutadisha, imikhiqizo efanelekile ngamalensi athuthukayo, ama-lens wokulwa nokulwa nokuvimbela, kanye nokuvimbela ama-MyOpia kanye namalensi okulawula ngokuqamba kwe-peripheral defocus design.
Abantu abadala bakhetha kanjani?
Njengoba abantu bekhula, i-lens kancane kancane, futhi umthethonqubo uncipha, ukuze kancane kancane athole umbono ofiphele nobunzima ekuboneni eduze, okuyinto evamile yomzimba, okungukuthi, presbyopia. Uma zinamaphutha aphindaphindeke lapho ebuka ibanga, bayoba nombono ofiphele kuwo wonke amabanga. Ngakho-ke, isidingo sabo esikhulu ukubona kahle nangokunethezeka kuwo wonke amabanga - kude, okuphakathi nendawo, futhi eduze - nokwanelisa lonke inqubo yekhwalithi ephakeme yokubona.
Okwesibili, ubungozi bezifo ezahlukahlukene zamehlo (ama-cataracts, ama-glaucoma, njll.) Lenyuka ngeminyaka, ngakho-ke futhi badinga izinga elithile lokuvikelwa kwe-UV.
Uma izidingo ezingenhla zihlangatshezwa, abantu abaneminyaka ephakathi nendawo nabadala bangakhetha ama-PhotoChromic lens ye-Presbyopia, abalungele kakhulu kubo. Okwamanje, uma bebuka ama-TV amaningi kanye namaselula, ama-lens we-Photochromic angu-Anti-Blue Light awukulikhekela okuhle.
Ngamagama, amaqembu ahlukene weminyaka, enezidingo ezihlukile ezibonakalayo, adinga izindlela ezahlukahlukene zokuhlolwa kwempilo kwamehlo ukuze acacise amapharamitha welensi ebekiwe nemikhiqizo ehlukene ukwanelisa abantu abehlukene.
