Mefuta e meraro ea lintho tse bonahalang
Lilense tsa khalase
Mehleng ea pele, thepa e ka sehloohong ea lilense e ne e le khalase ea optical.Sena se bakoa haholo ke hore ha ho nahanoa ka phetisetso e phahameng le ho hlaka ha lilense tsa khalase ea optical, theknoloji e batla e holile ebile e bonolo.Leha ho le joalo, bothata bo boholo ka ho fetisisa ba lilense tsa khalase ke tšireletso, ho hanyetsa ha eona hoa fokola, ho bonolo haholo ho senya, 'me ka lebaka la thepa ea eona e boima, ha e phutholohe ho apara, kahoo ha e sebelisoe hangata 'marakeng hona joale.
Lilense tsa resin
Lense ea Resin ke mofuta oa lense ea optical e entsoeng ka resin joalo ka thepa e tala, e sebetsoa, ea kopantsoe le ho belisoa ka ts'ebetso e nepahetseng ea lik'hemik'hale.Hona joale, lense ea resin ke lisebelisoa tse sebelisoang ka ho fetisisa.Boima ba lense ea resin bo bobebe ho feta ba lense ea khalase ea optical, 'me ho hanyetsa tšusumetso ho matla ho feta khalase,' me ha ho bonolo ho robeha, kahoo ho bolokehile ho sebelisoa.Mabapi le theko, lilense tsa resin le tsona li theko e tlase.Empa khanyetso ea lense ea resin e fokola, lebelo la oxidation le potlakile, bokaholimo ba lense bo bonolo ho kangoa.
Lilense tsa PC
Lense ea PC ke mofuta oa lense e entsoeng ka polycarbonate (thermoplastic material) ka mor'a ho futhumatsa le ho bōptjoa.Mofuta ona oa thepa o ile oa ntlafatsoa ho tloha lenaneong la sebaka, kahoo o boetse o bitsoa filimi ea sebaka kapa filimi ea sebaka.Resin ea PC ke mofuta oa thepa ea thermoplastic e sebetsang hantle, ka hona e loketse ho etsa likhalase tsa mahlo.Khanyetso ea tšusumetso ea lense ea PC e ntle haholo, e batla e sa robehe, e sireletsehile haholo.Mabapi le boima ba 'mele, e bobebe ho feta lilense tsa resin.Empa lense ea PC e tla ba le bothata ba ho e sebetsa, kahoo theko e batla e phahame.
Ho phethela:
| Lintho tse bonahalang | Molemo | Khaello |
| Lense ea khalase | High transmittance le refractive index, apara ho hanyetsa | E boima ebile e bonolo ho robeha |
| Lense ea resin | Leseli, ha le robehe habonolo, theko e tlase | Ho bonolo ho ngoapa |
| Lense ea PC | E bobebe ebile e sa robehe habonolo | Ho bonolo ho otlolla le theko e phahameng |
Boitsebiso bo loketseng ba hōlileng
Presbyopia ea maqheku e khothalelitse ho khetha lilense tsa khalase kapa lilense tsa resin.Ka kakaretso, presbyopia ke filimi e tlaase ea hyperopia, e sa hlokeng boima ba lense e phahameng, 'me coefficient ea ho sisinyeha ha batho ba hōlileng ha e phahame.Khalase kapa filimi ea resin e thata haholo e hanyetsana le mengoapo, 'me ts'ebetso ea optical le eona e ka tšoarella.
Boitsebiso bo loketseng batho ba baholo
Lilense tsa resin li loketse batho ba bacha le ba lilemong tse bohareng.Khetho ea lense ea resin e pharaletseng, ho latela phapang ea index ea refractive, phapang ea ts'ebetso, phapang ea ho tsepamisa maikutlo, e ka fihlela litlhoko tse fapaneng tsa batho ba fapaneng.
Boitsebiso bo loketseng bana le bacha
Batsoali ba eletsoa ho khetha lilense tse entsoeng ka matlapa a PC kapa thepa ea Trivex.Ha li bapisoa le lilense tse ling, lilense tsena ha li bobebe feela ka boima ba 'mele, empa hape li na le ho hanyetsa tšusumetso e ntle le polokeho e phahameng.Eseng hoo feela, matlapa a PC le lilense tsa Trivex le tsona li sireletsa mahlo a hau mahlaseling a UV.
Lense ea mofuta ona e na le ho tiea ho matla 'me ha ho bonolo ho robeha, kahoo e bitsoa lense ea tšireletso.Ka ligrama tse 2 feela ka cubic centimeter, ke thepa e bobebe ho feta e fumanehang bakeng sa lilense.Likhalase bakeng sa bana ha li tšoanelehe bakeng sa lilense tsa khalase, hobane bana ba mafolofolo, 'me lilense tsa khalase li senyeha, haeba li robehile, li ka utloisa mahlo bohloko.
O ngotse qetellong
Lilense tsa thepa e fapaneng li na le litšobotsi tse fapaneng haholo tsa sehlahisoa.Letlapa la khalase le boima ebile le na le ntlha e tlase ea polokeho, empa le hanana le ho ngoaha ebile le na le nako e telele ea tšebeliso.E loketse batho ba tsofetseng ba nang le boikoetliso bo fokolang le presbyopia e tlase.Lense ea resin e na le mesebetsi e mengata e fapaneng, e loketseng bacha ba nang le litlhoko tse fapaneng tsa ho ithuta le tsa mosebetsi;Tšireletseho ea lense ea bana, litlhoko tsa ho nkeha li phahame, lense ea PC ke khetho e molemo.
