Inkqubo eqhubelekayo yokufaka izinto ezininzi
1. Nxibelelana kwaye uqonde iimfuno zakho zombono, kwaye ubuze ngembali yakho yeglasi, umsebenzi, kunye neemfuno zeendondo ezintsha.
2. I-Optometry yekhompyutha kunye ne-single-eye interpupillary distance measurement.
3. Uviwo lombono we-spectacle ze/ze-original, xa kumiselwa i-diopta yomgama, malusekelwe kwi- diopta yeeglasi zokuqala kunye neemfuno zokubona umgama.
4. Umgaqo we-retinoscopy kunye ne-subjective refraction (umbono womgama) ukumisela umgama we-diopter kukuba: ngokusekelwe kumgaqo wombono owamkelekileyo wokubona umgama, i-myopia ingaba ncinane kangangoko kunokwenzeka, i-hyperopia inokwanela ngokusemandleni, kwaye i-astigmatism yongezwa.Lumka kwaye ugcine amehlo akho elungelelene.
5. Ukulungiswa kombono womgama, lungisa kwaye uqinisekise i-lens kunye ne-diopta yomgama phambi kwamehlo esifundo, kwaye uvumele isifundo sinxibe ukugqiba ukuba i-diopta yomgama yamkelekile.
6. I-Near-presbyopia/presbyopia measurement.
7. Zama ukulungisa umbono okufutshane, lungisa kwaye uqinisekise.
8. Intshayelelo kunye nokukhethwa kweentlobo zeelensi eziqhubekayo kunye nezixhobo.
9. Kucetyiswa ukuba ukhethe isakhelo.Khetha isakhelo esihambelanayo ngokwahlukileyoiilensi eziqhubekayoukhetha, kwaye uqinisekise ukuba kukho umgama owaneleyo othe nkqo ukusuka kumbindi womfundi ukuya kwelona nqanaba lisezantsi kumda osezantsi wesakhelo.
10. Ukubunjwa kwesakhelo, umgama phakathi kweeglasi zamehlo ngu-12 ~ 14mm.I-engile yokuthambeka phambili yi-10°~12°.
11. Umlinganiselo wobude bomfundi weliso elinye.
12. Ukumiselwa kweeparamitha zomlinganiselo wefilimu oqhubekayo.
13. Isikhokelo malunga nokusetyenziswa kweelensi eziqhubekayo.Kukho iimpawu kwiilensi.Khangela ukuba i-crosshairs ibekwe embindini womfundi kwaye unqume ukusetyenziswa kwayo yonke imigama.
Ukhetho oluqhubelekayo lwesakhelo sezinto ezininzi
Ukukhethwa kwezakhelo, okokuqala kufuneka ukuba indawo ephakathi yomfundi ukuya kumda wangaphakathi wesakhelo esisezantsi sesakhelo ngokuqhelekileyo singabi ngaphantsi kwe-22mm.Ubude bomjelo oqhelekileyo we-18mm okanye i-19mm isakhelo kufuneka kube ≥34mm, kwaye itshaneli emfutshane i-13.5 okanye i-14mm ukuphakama kwesakhelo kufuneka ibe ≥ 30mm, kwaye ugweme ukukhetha iifreyimu nge-bevel enkulu kwicala lempumlo, kuba kulula "ukunqunyulwa." "indawo yokufunda.Zama ukungakhethi izakhelo ezingenasakhelo, ekulula ukuzikhulula kunye nokutshintsha iiparameters ezahlukeneyo.Kwakhona qiniseka ukuba ukhetha izakhelo ezineempumlo ezilungelelanisiweyo.
Ukumakishwa okuqhubelekayo kogxininiso oluninzi
Ngaphambi kokulinganisa, isakhelo kufuneka sihlengahlengiswe kwaye silinganiswe ukuze sifumane ibhalansi engcono.Umgama phakathi kweeglasi zamehlo ngokuqhelekileyo ngu-12-13mm, i-angle yangaphambili i-10-12 degrees, kwaye ubude beetempile bufanelekile.
1. Umvavanyi kunye nomntu ovavanywayo bahlala ngokuchasene nomnye kwaye bagcina amehlo abo kwinqanaba elifanayo.
2. Umvavanyi ubambe usiba lokumakisha esandleni sakhe sasekunene, avale iliso lasekunene, avule iliso lasekhohlo, abambe isibane sohlobo losiba ngesandla sasekhohlo aze asibeke phantsi kwenwebu elingezantsi leliso lasekhohlo, aze acele lowo uhlolwayo ukuba afake isibane esifana nosiba. jonga iliso lasekhohlo lomvavanyi.Phawula umgama we-interpupillary kunye nemigca enqamlezileyo kwisampulu yeeglasi ezisekelwe kwimbonakalo evela embindini womfundi wesifundo.Umgama othe nkqo ukusuka ekudibaneni kwemigca enqamlezayo ukuya kumda osezantsi wesakhelo kubude bomfundi weliso lasekunene lesifundo.
3. Umvavanyi ubambe i-marker ngesandla sasekunene, avale iliso lasekhohlo, avule iliso lasekunene, abambe ipenlight ngesandla sasekhohlo aze ayibeke phantsi kwenwebu elingezantsi leliso lasekunene, acele umvavanyi ukuba ajonge ngasekunene komvavanyi. iliso.Phawula umgama we-interpupillary kunye nemigca enqamlezileyo kwisampulu yeeglasi ezisekelwe kwimbonakalo evela embindini womfundi wesifundo.Umgama othe nkqo ukusuka ekudibaneni kwemigca enqamlezayo ukuya kumda osezantsi wesakhelo kubude bomfundi weso lasekhohlo lesifundo.
Wisithethe kude kube sekupheleni
Iilensi ezininzi eziqhubekayokuyabiza ukwenza kwaye ziilensi ezisebenzayo.Zijoliswe kubantu abangakwazi ukulungelelanisa ngokwaneleyo.Abakwazi ukubona ngokucacileyo kuluhlu olusondeleyo (umgama wokufunda 30 cm), nokuba ngamehlo enyama okanye ukunxiba iindondo, okanye ababoni ngokucacileyo kuluhlu olusondeleyo ngombono osebenzayo., kufuneka unxibe iiglasi ngexesha okanye kufuneka utshintshe iiglasi.Kufuneka kuqatshelwe apha ukuba umgaqo wokugqoka iiglasi ze-presbyopia yeyona nto ibhetele ebonakalayo kunye neqondo eliphezulu, ukuqinisekisa izinto ezicacileyo kunye nokunciphisa umthwalo wokudinwa kwamehlo obangelwa ngumbono osondeleyo kangangoko kunokwenzeka.
