Maitiro ekugadzirisa zvinhu zvakawanda zvinofamba-famba
1. Taurai uye nzwisisai zvamunoda kuona, uye bvunzai nezvenhoroondo yemagirazi enyu, basa renyu, uye zvinodiwa pamagirazi matsva.
2. Kuyera daro revana vari pakati pevana nemaziso (computer optometry) uye kuyerwa kwedaro pakati pevana vari pakati pevana nemaziso.
3. Kuongororwa kwekuona kwemaziso asina kupfeka/pakutanga, pakusarudza daro re diopter, kunofanirwa kuenderana ne diopter yemagirazi ekutanga uye zvinodiwa pakuona kure.
4. Nheyo ye retinoscopy uye refraction yemunhu (kuona kure) yekuona daro re diopter ndeiyi: zvichibva panheyo yekuona kure kunogamuchirwa, myopia inogona kuva isina kudzika sezvinobvira, hyperopia inogona kukwana sezvinobvira, uye astigmatism inowedzerwa. Chenjerera uye chengeta maziso ako akaenzana.
5. Kuti ugadzirise kuona kure, gadzirisa uye simbisa lenzi ne diopter yekureba iri pamberi pemaziso emunhu ari kurwara, uye rega munhu ari kurwara aipfeke kuti aone kana diopter yekureba ichigamuchirwa.
6. Kuyerwa kweNear-presbyopia/presbyopia.
7. Edza kugadzirisa kuona kwepedyo, gadzirisa wobva wasimbisa.
8. Sumo nesarudzo yemhando dzemalenzi anofambira mberi nezvinhu.
9. Zvinokurudzirwa kusarudza furemu. Sarudza furemu inoenderana zvichienderana nemufananidzo wakasiyanamagirazi anofambira mberiUnosarudza, uye iva nechokwadi chekuti pane daro rakakwana kubva pakati pepure kusvika panzvimbo yakaderera yemucheto wezasi wefuremu.
10. Kuumbwa kwefuremu, daro riri pakati pemagirazi emaziso i12~14mm. Kona yekurerekera mberi i10°~12°.
11. Kuyera kukwirira kwemboni yeziso rimwe chete.
12. Kuziva maparamita ekuyera firimu rinofambira mberi.
13. Mazano ekushandisa malenzi anofambira mberi. Pane zviratidzo pamalenzi. Tarisa kana mativi ebvudzi ari pakati pemboni uye sarudza mashandisirwo ese edaro.
Sarudzo yemafuremu e multifocal anofambira mberi
Pakusarudza mafuremu, zvinodikanwa kutanga kuti nzvimbo yepakati pepurepi kusvika kumucheto wemukati wefuremu rezasi refuremu kazhinji isingasviki 22mm. Kureba kwefuremu yemugero we18mm kana 19mm kunofanira kunge kuri ≥34mm, uye kukwirira kwefuremu yemugero we13.5 kana 14mm kunofanira kunge kuri ≥ 30mm, uye dzivisa kusarudza mafuremu ane bevel hombe parutivi rwemhino, nekuti zviri nyore "kucheka" nzvimbo yekuverenga. Edza kusasarudza mafuremu asina furemu, ari nyore kusunungura nekuchinja maparamita akasiyana-siyana. Iva nechokwadi chekusarudza mafuremu ane mapedhi emhino anogadziriswa.
Kucherechedza zvinhu zvakawanda zvinofambira mberi
Usati wayera, furemu inofanira kugadziriswa uye kugadziriswa kuti iwane chiyero chakanakisa. Daro riri pakati pemagirazi emaziso rinowanzova 12-13mm, kona yekumberi iri 10-12 degrees, uye kureba kwematemberi kwakakodzera.
1. Muongorori nemunhu ari kuongororwa vanogara vakatarisana uye vanoramba vachiona zvakaenzana.
2. Muongorori akabata peni yechiratidzo muruoko rwake rwerudyi, anovhara ziso rake rerudyi, anovhura ziso rake reruboshwe, anobatisa tochi yakaita sepeni muruoko rwake rweruboshwe oiisa pasi peziso rezasi reziso reruboshwe, obva akumbira muongorori kuti atarise ziso reruboshwe remuongorori. Maka daro repakati pevana nemitsara yakachinjika pamuenzaniso wemagirazi zvichibva pamufananidzo wepakati pemwana wemunhu. Daro rakamira kubva pakusangana kwemitsetse yakachinjika kusvika kumucheto wepakati wezasi wefuremu ndiko kureba kwemwana weziso rerudyi remunhu.
3. Muongorori akabata chiratidzo muruoko rwake rwerudyi, anovhara ziso rake reruboshwe, anovhura ziso rake rerudyi, anobatisa chiedza chepenlight muruoko rwake rweruboshwe ochiisa pasi peziso rezasi reziso rake rerudyi, achikumbira muongorori kuti atarise ziso rerudyi remuongorori. Maka daro repakati pevana nemitsara yakachinjika pamuenzaniso wemagirazi zvichibva pamufananidzo wepakati pemwana wemunhu. Daro rakamira kubva pakusangana kwemitsetse yakachinjika kusvika kumucheto wepakati wezasi wefuremu ndiko kureba kwemwana weziso reruboshwe remunhu.
Wtsika kusvika kumagumo
Magirazi e multifocal anofambira mberiZvinodhura kugadzira uye magirazi anoshanda. Akagadzirirwa vanhu vasina kugona kugadzirisa zvakakwana. Havagone kuona zvakajeka vari pedyo (kure ne30 cm), kungave nemaziso asina kupfeka kana kupfeka magirazi, kana kuti havagone kuona zvakajeka vari pedyo nekuona. , unofanira kupfeka magirazi nenguva kana kuti unofanira kuchinja magirazi. Zvinofanira kucherechedzwa pano kuti musimboti wekupfeka magirazi epresbyopia ndiyo nzira yakanakisisa yekuona uye yepamusoro, kuve nechokwadi chekuti zvinhu zvakajeka uye kuderedza mutoro wekuneta kwemaziso kunokonzerwa nekuona pedyo zvakanyanya sezvinobvira.
