Mutsara wezvinhu zvitatu
Magirazi egirazi
Mumazuva ekutanga, chinhu chikuru che lenses chaiva girazi remaziso.Izvi zvinonyanya kuitika nekuti tichifunga nezve yakakwira transmittance uye kujeka kwemagirazi egirazi lenzi, tekinoroji yakakura uye iri nyore.Zvisinei, dambudziko guru regirazi lenses nderokuchengetedza, kukanganisa kwayo kupikisa kwakashata, zviri nyore kuputsika, uye nekuda kwechinhu chayo chinorema, haina kugadzikana kupfeka, saka haisati yashandiswa mumusika panguva ino.
Iyo resin lenzi
Resin lens imhando yeoptical lens yakagadzirwa neresin seyakagadzirwa zvinhu, yakagadziriswa, yakagadzirwa uye yakakwenenzverwa nechaiyo kemikari maitiro.Parizvino, resin lens ndiyo inonyanya kushandiswa zvinhu.Huremu hweresin lens hwakareruka pane hwegirazi regirazi lens, uye mhedzisiro yekupikisa yakasimba kupfuura girazi, uye haisi nyore kupwanya, saka haina njodzi kushandisa.Panyaya yemutengo, resin lenses zvakare inokwanisika.Asi kusamira kwekupfeka kweresin lens kwakashata, iyo oxidation kumhanya inokurumidza, iyo lens pamusoro iri nyore kukwenya.
Iyo PC lenses
PC lens imhando yelenzi yakagadzirwa nepolycarbonate (thermoplastic material) mushure mekupisa nekuumbwa.Rudzi urwu rwezvinhu rwakagadzirwa kubva kuchirongwa chemuchadenga, saka inonziwo firimu remuchadenga kana firimu remuchadenga.PC resin imhando ye thermoplastic material ine mashandiro akanaka, saka inonyanya kukodzera kugadzira magirazi emaziso.PC lens kukanganisa kuramba yakanaka kwazvo, inenge isina kuputsika, yakanyanya kuchengetedzeka.Panyaya yehuremu, yakareruka kupfuura resin lenzi.Asi PC lens ichave nedambudziko mukugadzirisa, saka mutengo wakakwira.
Kupedzisa:
| Material | Advantage | Kushomeka |
| Girazi lenzi | High transmittance uye refractive index, kupfeka kuramba | Inorema uye iri nyore kuputsa |
| Resin lens | Chiedza, kwete nyore kuputsika, mutengo wakaderera | Zviri nyore kukwenya |
| PC lenzi | Chiedza uye kwete nyore kuputsika | Zviri nyore kukwenya uye mutengo wakakwira |
Mashoko akakodzera kune vakwegura
Vakuru vepresbyopia vakakurudzira kusarudza magirazi egirazi kana resin lenzi.Kazhinji, presbyopia ifirimu yakaderera-degree hyperopia, iyo isingade yakakwira lens uremu, uye iyo coefficient yekufamba kwevakwegura haina kukwirira.Girazi kana super-yakaoma resin firimu inoshingirira kukwenya, uye kuita kwemaziso kunogonawo kugara kwenguva refu.
Material akakodzera vanhu vakuru
Resin lenses akakodzera kune vechidiki uye vepakati-vezera.Kusarudzwa kweresin lens kwakakura, zvichienderana nerefractive index distinction, functional distinction, refractive focus distinction, inogona kusangana nezvinodiwa zvakasiyana zvevanhu vakasiyana.
Inokodzera zvinhu zvevana nevechiri kuyaruka
Vabereki vanorayirwa kuti vasarudze lenzi dzakagadzirwa nePC mahwendefa kana Trivex zvinhu.Kuenzaniswa nemamwe malenzi, malenzi aya haangoreruke muhuremu, asi zvakare ane zvirinani kukanganisa kupikisa uye kuchengetedzwa kwepamusoro.Kwete izvozvo chete, mahwendefa ePC uye Trivex lenses anodzivirirawo maziso ako kubva ku UV mwaranzi.
Iri rudzi rwelenzi rine kusimba kwakasimba uye haisi nyore kuputsika, saka inonzi kuchengetedza lens.Pamagiramu maviri chete pa cubic centimita, ndiyo yakapfava zvinhu zviripo kumalenzi.Magirazi evana haana kukodzera magirazi egirazi, nokuti vana vari kushanda, uye magirazi egirazi haana kusimba, kana akaputsika, anogona kukuvadza maziso.
Akanyora kekupedzisira
Malenzi ezvigadzirwa zvakasiyana ane akasiyana kwazvo echigadzirwa maitiro.Iro girazi rinorema uye rine yakaderera kuchengetedza chinhu, asi rinoshingirira kukwenya uye rine nguva refu yekushandisa kutenderera.Inokodzera vakweguru vane kurovedza muviri kushoma uye yakaderera degree presbyopia.Resin lens ine mabasa akasiyana-siyana, akakodzera vechidiki mune zvakasiyana-siyana zvekudzidza uye zvekushanda zvinodiwa;Kuchengeteka kwema lens evana, zvinodiwa zvekutakura zvakakwirira, PC lens isarudzo iri nani.
