Izinto ezintathu ezinkulu zamalensi optical: imuphi umehluko othize kanye nezinzuzo kanye nokubi kwamalensi amathathu adumile abonakalayo.Ukufaka izibuko zolwazi lwamalensi, sethule uhlobo lomsebenzi welensi, ukucaciswa kwezinto ezidluliswa kancane, kulokhu sigxila ezintweni ezintathu eziyinhloko zelensi: ingilazi lens/resin lens/PC lens.

Ukuhlukaniswa kwezinto ezintathu
Amalensi engilazi
Ezinsukwini zokuqala, izinto eziyinhloko zamalensi kwakuyingilazi ye-optical.Lokhu kungenxa yokuthi uma kucatshangelwa ukudluliswa okuphezulu nokucaca kwamalensi engilazi optical, ubuchwepheshe buvuthiwe futhi bulula.Kodwa-ke, inkinga enkulu yama-lens engilazi ukuphepha, ukumelana kwayo komthelela kumpofu, kulula kakhulu ukuphuka, futhi ngenxa yezinto zayo ezinzima, akukhululekile ukugqoka, ngakho-ke akuvamile ukusetshenziswa emakethe okwamanje.
Amalensi e-resin
I-resin lens iwuhlobo lwelensi yokubona eyenziwe nge-resin njengempahla eluhlaza, ecutshungulwayo, ehlanganisiwe futhi yapholishwa ngenqubo yamakhemikhali enembile.Njengamanje, i-resin lens iyinto esetshenziswa kakhulu.Isisindo selensi ye-resin silula kunelensi yengilazi ebonakalayo, futhi ukumelana komthelela kunamandla kunengilazi, futhi akulula ukuphuka, ngakho kuphephe kakhudlwana ukukusebenzisa.Ngokwentengo, amalensi e-resin nawo athengeka kakhulu.Kodwa ukumelana nokugqokwa kwelensi ye-resin kubi, isivinini se-oxidation siyashesha, indawo engaphezulu yelensi kulula ukuklwebheka.
Amalensi e-PC
I-PC lens iwuhlobo lwamalensi enziwe nge-polycarbonate (i-thermoplastic material) ngemva kokushisisa nokubunjwa.Lolu hlobo lwezinto lwakhiwe kusukela ohlelweni lwesikhala, ngakho lubizwa nangokuthi ifilimu yesikhala noma ifilimu yesikhala.I-PC resin iwuhlobo lwe-thermoplastic material esebenza kahle, ngakho ifaneleka kakhulu ukwenza izibuko zamehlo.Ukumelana nomthelela welensi ye-PC kuhle kakhulu, cishe akuphukanga, ukuphepha okuphezulu kakhulu.Mayelana nesisindo, ilula kunama-resin lens.Kodwa i-PC lens izoba nobunzima ekucubunguleni, ngakho intengo iphakeme kakhulu.
Ngamafuphi:
| Okubalulekile | Inzuzo | Ukushoda |
| Ilensi yengilazi | I-transmittance ephezulu kanye ne-refractive index, ukumelana nokugqoka | Inzima futhi kulula ukuphuka |
| I-resin lens | Ilula, ayinqamuki kalula, intengo ephansi | Kulula ukunwaya |
| Ilensi ye-PC | Ilula futhi ayinqamuki kalula | Kulula ukuklwebha futhi intengo ephezulu |
Izinto ezifanele asebekhulile
I-presbyopia yabadala iphakamise ukukhetha amalensi engilazi noma amalensi eresin.Ngokuvamile, i-presbyopia ifilimu ye-hyperopia enezinga eliphansi, engadingi isisindo se-lens esiphezulu, futhi i-coefficient yokunyakaza yasebekhulile ayikho phezulu.Ifilimu yengilazi noma ye-super-hard-hard imelana kakhulu nokuklwebheka, futhi nokusebenza kokubona kungase kuhlale isikhathi eside.
Izinto ezifanele abantu abadala
Ama-resin lens afanele abantu abasha nabaphakathi.Ukukhethwa kwelensi ye-resin kubanzi, ngokuya ngomehluko wenkomba ye-refractive, umehluko wokusebenza, ukuhlukaniswa kwe-refractive focus, kungahlangabezana nezidingo ezahlukene zabantu abahlukene.
Izinto ezifanele izingane kanye nentsha
Abazali bayelulekwa ukuba bakhethe ama-lens enziwe ngamaphilisi e-PC noma izinto ze-Trivex.Uma kuqhathaniswa namanye ama-lens, lawa ma-lens awagcini nje ngokulula ngesisindo, kodwa futhi anokumelana nomthelela ongcono nokuphepha okuphezulu.Akugcini lapho, amaphilisi e-PC namalensi e-Trivex nawo avikela amehlo akho emisebeni ye-UV.
Lolu hlobo lwamalensi lunokuqina okuqinile futhi akulula ukuphuka, ngakho lubizwa ngokuthi ilensi yokuphepha.Kumagremu angu-2 kuphela cubic centimitha ngayinye, iyinto elula kunazo zonke etholakalayo yamalensi.Izibuko zezingane azifanelekile kuma-glass lens, ngoba izingane ziyasebenza, futhi ama-glass lens abuthakathaka, uma ephukile, angase alimaze amehlo.
Ubhale okokugcina
Amalensi ezinto ezahlukene anezici zomkhiqizo ezihluke kakhulu.Ishidi lengilazi liyasinda futhi linesici sokuphepha esiphansi, kodwa alikwazi ukuklwejwa futhi linomjikelezo omude wokusebenzisa.Ilungele abantu asebekhulile abanokuzivocavoca okuncane kanye ne-presbyopia enezinga eliphansi.I-resin lens inemisebenzi eminingi ehlukahlukene, elungele abantu abasha ngezidingo ezahlukahlukene zokufunda nomsebenzi;Ukuphepha kwelensi yezingane, izidingo zokuphatheka ziphezulu, ilensi ye-PC iyisinqumo esingcono.
