Ho hlophisoa ha lisebelisoa tse tharo tse kholo
Lilense tsa khalase
Mehleng ea pele, thepa e ka sehloohong ea lilense e ne e le khalase ea optical.Sena se ne se bakoa haholo ke hore lilense tsa khalase tsa optical li na le phetiso ea khanya e phahameng, e hlakileng, le mekhoa ea tlhahiso e batlang e holile ebile e bonolo.Leha ho le joalo, bothata bo boholo ka lilense tsa khalase ke polokeho ea bona.Li na le khanyetso e fokolang ea tšusumetso 'me li bonolo haholo ho li senya.Ho phaella moo, li boima ebile ha li phutholohe ho apara, kahoo kopo ea bona ea 'maraka ea hona joale e fokotsehile.
Lilense tsa resin
Lilense tsa resin ke lilense tsa mahlo tse entsoeng ka resin joalo ka thepa e tala, e sebetsoa le ho kopanngoa ka lits'ebetso tse nepahetseng tsa lik'hemik'hale le ho belisoa.Hona joale, lisebelisoa tse sebelisoang haholo bakeng sa lilense ke resin.Lilense tsa resin li bobebe ka boima ba tsona ha li bapisoa le lilense tsa optical glass 'me li na le matla a ho hanyetsa ho feta lilense tsa khalase, e leng se etsang hore li se ke tsa robeha, kahoo ho bolokehile ho li sebelisa.Mabapi le theko, lilense tsa resin le tsona li theko e tlase.Leha ho le joalo, lilense tsa resin li na le khanyetso e mpe ea ho ingoaea, li oxidize kapele, 'me li na le monyetla oa ho ba le mengope e kaholimo.
Lilense tsa PC
Lilense tsa PC ke lilense tse entsoeng ka polycarbonate (thermoplastic material) tse entsoeng ka ho futhumatsa.Thepa ena e simolohile lipatlisisong tsa lenaneo la sepakapaka hape e tsejoa e le lilense tsa sebaka kapa lilense tsa cosmic.Hobane resin ea PC ke thepa ea thermoplastic e sebetsang hantle haholo, e loketse ho etsa lilense tsa khalase ea mahlo.Lilense tsa PC li na le ts'ebetso e matla ea ho hanyetsa, hoo e ka bang ha ho mohla li senyehang, 'me li bolokehile haholo ho li sebelisa.Mabapi le boima ba 'mele, li bobebe ho feta lilense tsa resin.Leha ho le joalo, lilense tsa PC ho ka ba thata ho li sebetsa, ho etsa hore li theko e boima.
Thepa e Loketseng Bakeng sa Batho ba Hōlileng
Bakeng sa batho ba tsofetseng ba nang le presbyopia, ho khothalletsoa ho khetha lilense tsa khalase kapa lilense tsa resin.Presbyopia hangata e hloka likhalase tsa ho bala tse nang le matla a tlase, kahoo boima ba lilense ha se taba e bohlokoa haholo.Ho feta moo, batho ba tsofetseng hangata ha ba sebetse hantle, ba etsa hore lilense tsa khalase kapa lilense tse thata tsa resin li se ke tsa hlola, ha li ntse li netefatsa ts'ebetso ea mahlo e tšoarellang nako e telele.
Thepa e Loketseng Batho ba Baholo
Lilense tsa resin li loketse batho ba lilemong tse bohareng le ba bacha.Lilense tsa resin li fana ka mefuta e mengata ea likhetho, ho kenyeletsoa karohano e ipapisitseng le index ea refractive, ts'ebetso, le lintlha tse shebaneng le tsona, ka hona, li fihlela litlhoko tse fapaneng tsa lihlopha tse fapaneng.
Boitsebiso bo Loketseng Bakeng sa Bana le Bacha
Ha u khetha likhalase bakeng sa bana, batsoali ba eletsoa ho khetha lilense tse entsoeng ka thepa ea PC kapa Trivex.Ha ho bapisoa le mefuta e meng ea lilense, lisebelisoa tsena ha li bobebe feela empa hape li fana ka khanyetso e ntle ea tšusumetso le polokeho e phahameng.Ho feta moo, lilense tsa PC le Trivex li ka sireletsa mahlo mahlaseling a kotsi a UV.
Lilense tsena li thata haholo ebile ha li robehe habonolo, ka hona li bitsoa lilense tsa polokeho.Li boima ba ligrama tse 2 feela ka cubic centimeter, hajoale ke lisebelisoa tse bobebe tse sebelisoang bakeng sa lilense.Ha ea lokela ho sebelisa lilense tsa khalase bakeng sa likhalase tsa bana, kaha bana ba mafolofolo 'me lilense tsa khalase li atisa ho robeha, tse ka senyang mahlo.
Ha re phethela
Litšobotsi tsa sehlahisoa sa lilense tse entsoeng ka thepa e fapaneng li fapane haholo.Lilense tsa likhalase li boima ebile li na le ntlha e tlase ea polokeho, empa ha li thibane 'me li na le nako e telele ea tšebeliso, e leng se etsang hore li tšoanele batho ba hōlileng ba nang le maemo a tlaase a ho ikoetlisa le presbyopia e bonolo.Lilense tsa resin li tla ka mefuta e mengata mme li fana ka ts'ebetso e felletseng, e li etsang hore li tšoanelehe bakeng sa litlhoko tse fapaneng tsa boithuto le tsa mosebetsi tsa batho ba lilemo tse mahareng le ba bacha.Ha ho tluoa ho likhalase tsa mahlo tsa bana, polokeho e phahameng le bobebe lia hlokahala, ho etsa hore lilense tsa PC e be khetho e ntle.
Ha ho na thepa e ntle ka ho fetisisa, ke tlhokomeliso e sa fetoheng ea bophelo bo botle ba mahlo.Ha re khetha lilense tse entsoeng ka thepa e sa tšoaneng, re tlameha ho nahana ka pono ea bareki, re ntse re hopola melao-motheo e meraro ea ho kenya likhalase tsa mahlo: boiketlo, ho tšoarella, le botsitso.
