Omnye wemibuzo abantu abaninzi beva xa befumana iilensi zabo ezilungiselelwe, "Yeyiphi isalathiso sokuphinda siyifunayo?" Ndiyakholelwa ukuba abantu abaninzi abayiqondi lekota, masifunde ngayo namhlanje!
Abantu abaninzi kuluntu lwanamhlanje bakholelwa ukuba iiglasi ezibizayo zingcono, zibhetele! Uninzi lwamehlo, ukubamba le psychology yabathengi, ihlala isebenzisa isalathiso sokuqaqamba njengendawo yokuthengisa ukwandisa ixabiso leeglasi ukuze ufumane izibonelelo eziphezulu zoqoqosho ukuze zifumane izibonelelo zoqoqosho eziphezulu. Oko kukuthi, ukuphakama kwesalathiso semali, ukucofa ilensi, kunye nexabiso eliphantsi kakhulu!
Eyona nto iphambili kwiilensi ezihlaziyiweyo kakhulu kukucinga kwabo. Abathengi ekukhetheni iilensi, kufuneka bakhethe ngokwedigri yangaphambili bavumelane nelensi, ukusebenzela okungathandekiyo kwelensi, engaboniyo yesalathiso esiphezulu esingathandekiyo asinqweneleki, kufanelekile okona kubaluleke kakhulu!
I-lenses elungileyo yokuthandela kufuneka ibhekiswe kwiilensi ngeempawu ezifanelekileyo zezinto ezibonakalayo, eziboniswe kwi-ofisi ephezulu, ukucaciswa okuphezulu, ukusasazeka okuncinci, ukunyangwa okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokuzikhusela kakuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokukhusela okuhle kunye nokuzikhusela kakuhle.
Usually the refractive index of lenses includes 1.49, 1.56, 1.61, 1.67, 1.74, 1.8, 1.9.
Ukusuka kwindawo yembono yokukhetha i-Indent Reffint ngokubanzi ngokubhekisele koku kulandelayo:
I-1. Inqanaba le-myopia.
I-myopia inokwahlulwa ibe yi-mypia ethobekileyo (ngaphakathi kwe-3.00 degrees), i-Iyopiya ephakathi (phakathi kwe-3.00 ne-6.00 degrees), i-mypia ephezulu (ngaphezulu kwe-6.00 degrees).
Ngokubanzi Ukukhanya kokukhanya kunye ne-mypia emodareyitha (i-400 degrees ngaphantsi kwe-Indeping ye-Recofeal ngu-1.56 Kulungile, (300 degrees ukuya kwi-1.61 okanye i-1,61 yesalathiso esingaphezulu. ilensi.
Ukuphakama kwesalathiso semali, kuko okokugqibela kwenzeka okoko kukhanya emva kokukhanya kudlula kwilensi, kunye nelensile ilensi. Nangona kunjalo, ukuphakama kwesalathiso semali, kokukhona i-panomenon engaphezulu kweyona nto iphambili yile, ngoko ke ilensi ephezulu yesalathiso inenombolo ye-ABBE. Ngamanye amagama, xa i-Inden yesalathiso iphezulu, ilensi inomthi, kodwa xa ujonge izinto, ukubonakala kombala akubobuzi xa kuthelekiswa ne-1.56 yesalathiso. Eyona nto ikhankanyiweyo apha ngumahluko omncinci ngokuhambelana. Ngetekhnoloji yangoku, ilensi enesalathiso esiphakamileyo se-Recockence inobugqwetha embonweni. I-lenses ephezulu yesalathiso i-Recances ihlala isetyenziswa kuphela amawaka eedigri.
2. Iimfuno ezikhoyo.
Ukukhetha isalathiso se-Refleting ngokwenqanaba le-myopia ayisiyo, kodwa kufuneka idityaniswe nokukhetha isakhelo kunye neyona meko yeliso ukuba lithathe isigqibo.
Ngoku i-myopic degree iphakame, kwi-Myapia yesihlanu ukuya kwi-10idu, isalathiso esisezantsi se-lens yelensi iya kuba yinto enkulu, okwangoku, ukuba siphakamisa ngaphezulu kwe-1.61 Isalathiso sokuqaqamba, ngaphezulu kokuba ukhetha isakhelo somfanekiso wokuphepha uhlobo lwebhokisi enkulu, iqondo lobuhle elibanzi, leglasi yobuhle kunye nentuthuzelo ziphila kakuhle.
Ukuqukumbela: Ukukhetha isalathiso se-Reflective kufuneka kusekwe kwicebiso le-oxtometrist ye-optometi, ngokwenqanaba le-myopia, ubungakanani be-myopia, ubungakanani besakhelo, iimfuno ezibonakalayo, iMonstong, eyona ibaluleke kakhulu.
