Izinombolo ezikudokotela wakho we-Eyeglass zihlobana nokwakheka kwamehlo akho namandla ombono wakho. Bangakusiza ekutholeni ukuthi unayo Ukuseduze, Ukungaziphathi kahle noma i-astigmatism - futhi kunani.
Uma wazi ukuthi yini okufanele uyibheke, ungazenzela izinombolo nezifinyezo eshadini lakho kadokotela.
I-OS vs. OS: eyodwa iso ngalinye
Odokotela bamehlo basebenzisa izifinyezo "OD" ne- "OS" ukuchaza amehlo akho kwesokudla nakwesobunxele.
● I-OD iso lakho lokunene. I-OD imfushane nge-oculus dexter, ibinzana lesiLatini le- "Eye Eye."
● I-OS iso lakho lesokunxele. I-OS imfushane nge-oculus sinister, isiLatini ngeso "ngakwesobunxele."
Umuthi wakho wokubuka ungahle ube nekholomu ebizwa ukuthi "Ou." Lesi isifinyezo seoculus urque, okusho ukuthi "Amehlo womabili" ngesiLatini. Lezi zinqubo ezifushanisiwe zivamile emiyalweni yezibuko, Amalensi wokuxhumana nemithi yeso, kepha abanye odokotela nemitholampilo bakhethe ukwenza kahle imiyalelo yabo yamehlo ngokusebenzisaRe (iso kwesokudla)na-I-LE (Eye Yesobunxele)esikhundleni se-OD ne-OS.
Sphere (skhh)
I-Sphere ibonisa inani lama-lens amandla anqunyelwe ukulungisa ukuseduze kwesendlalelo noma ekubiseni. Amandla we-lens alinganiswa kuma-diopters (D).
● Uma inombolo engaphansi kwalesi sihloko iza nesibonakaliso se-minus (-),Useduze.
● Uma inombolo engaphansi kwalesi sihloko inesibonakaliso sokuhlanganisa (+),UQHAWE.
Isilinda (CYL)
I-Cylinder ikhombisa inani lamandla welensi adingekayoI-Astigmatism. Ihlala ilandela amandla we-sphere ku-Eyeglass kadokotela.
Inombolo kwikholomu ye-cylinder ingaba nesibonakaliso sokususa (ukulungiswa kwe-atigmatism eseduze) noma isibonakaliso sokuhlanganisa (sokungafanele i-astigmatism).
Uma kungekho lutho oluvela kule kholamu, awunalo i-astigmatism, noma izinga lakho le-astigmatism lincane kakhulu kangangokuba alidingi ukulungiswa.
I-aksizi
I-Axis ichaza i-lens meridian equkethe amandla esilindalungisa ama-astigmatism.
Uma umuthi we-eyeglass uhlanganisa amandla esilinda, kufanele futhi afake inani le-axis, elilandela amandla wesilinda.
I-axis ichazwa ngenombolo ukusuka ku-1 kuye ku-180.
● Inombolo 90 ihambelana ne-meridian ebheke ngamehlo.
● Inombolo 180 ihambelana ne-meridian evundlile yeso.
Enezelela
"Faka"Kungezwe amandla okukhulisaKusetshenziswe engxenyeni engezansi yamalensi amaningi ukulungisa ama-Presbyopia - Ukudla okungokwemvelo okwenzeka ngeminyaka.
Inombolo evela kulesi sigaba somuthi ngaso sonke isikhathi i-A "PLUS", noma ngabe ungaboni uphawu lokuhlanganisa. Ngokuvamile, izosukela ku- + 10.75 kuya ku- + 3.00 d futhi izoba amandla afanayo kuwo womabili amehlo.
Intengo
Leli inani lamandla ePrismatic, elinganiswe kuma-prism diopters ("pd" noma unxantathu lapho ebhaliwe i-freehand), ebekiwe ukunxephezelaukuqondisisa kwamehloIzinkinga.
Amaphesenti amancane kuphela emithamo ye-eyeglass efaka isilinganiso se-prism.
Lapho ekhona, inani le-prism liboniswa kumayunithi ama-metric noma ama-ractoral English Units (0.5 noma ½, ngokwesibonelo), futhi ukuqondiswa kwe-Prims kuboniswa ngokulandela isikhundla sayo "isisekelo" (emaphethelweni amakhulu).
Izifinyezo ezine zisetshenziselwa ukuqondiswa kwe-prism: Bu = isisekelo; Bd = isekele; Bi = isisekelo ku (ngasekhaleni lomgqokile); Bo = isisekelo (endlebeni egqoke umgqomo).
