Ukuhlolwa kwamehlo kanye nodokotela wesibuko

Uma udinga ukulungiswa kombono ngemuva kokuhlolwa kwamehlo, udokotela wamehlo wakho noma udokotela wamehlo uzokwazisa uma ubona eduze noma ubheka kude. Bangaze bakutshele nokuthi une-astigmatism.

Ngokuthola noma yikuphi ukuxilongwa, uzonikezwa incwadi kadokotela yezilungiso zamehlo zokulungisa. Umuthi wakho kadokotela uzoba namagama ambalwa afushanisiwe anjenge:

• OD
• OS
• I-SPH
• I-CYL

Uyazi ukuthi kusho ukuthini lokhu? Siyachaza.

Kusho ukuthini i-OD vs. OS?

Isinyathelo sokuqala sokuqonda imiyalo evela kudokotela wakho wamehlo ukwazi i-OD ne-OS. Lezi izifinyezo nje zamagama esiLatini:

• I-OD isifinyezo se- "oculus dexter" okuyisiLatini esisho "iso langakwesokudla."
• I-OS isifinyezo se- "oculus sinister" okuyisiLatini esisho "iso lesobunxele."

Incwadi kadokotela yakho ingase futhi ibe nekholomu ye-OU, okuyisifushaniso se- “oculus uterque,” ​​isiLatin esisho “amehlo womabili.”

Yize i-OS ne-OD kuyizifinyezo zendabuko ezisetshenziselwa imiyalo yezingilazi zamehlo, amalensi okuxhumana, nemithi yamehlo, kukhona abanye odokotela abenze amafomu abo kadokotela ngokufaka i-OD esikhundleni se-RE (iso langakwesokudla) ne-OS nge-LE (iso lesobunxele).

Ezinye izifinyezo kumuthi wakho we-eyeglass

Ezinye izifinyezo ongazibona kumuthi wakho we-eyeglass zifaka i-SPH, i-CYL, i-Axis, i-Add, ne-Prism.

I-SPH

I-SPH isifinyezo se- “sphere” esibonisa amandla elensi adonswa ngudokotela wakho ukulungisa umbono wakho.

Uma ubona eduze (myopia), inombolo izoba nophawu lokususa (-). Uma ubonela kude (i-hyperopia), inombolo izoba nesibonakaliso sokuhlanganisa (+).

I-CYL

I-CYL isifinyezo se- "cylinder" esikhombisa amandla we-lens odokotela bakho abakunika wona ukulungisa i-astigmatism yakho. Uma ingekho inombolo kule kholamu, khona-ke udokotela wakho akatholanga i-astigmatism noma i-astigmatism yakho ayidingi ukulungiswa.

I-eksisi

I-eksisi inombolo kusuka ku-1 kuye ku-180. Uma udokotela wakho efake u-cylinder power, kuzoba khona nenani le-eksisi ukukhombisa ukuma. I-eksisi ilinganiswa ngamadigri futhi ibhekisa lapho kutholakala khona i-astigmatism ku-cornea.

Faka

I-Add isetshenziswa kuma-lens ahlukahlukene ukubonisa amandla okhulisa angeziwe engxenyeni engezansi yelensi.

I-Prism

I-Prism ivela kuphela kunani eliphansi lemigomo. Isetshenziswa lapho udokotela wakho ezwa ukuthi kudingeka isinxephezelo sokuqondaniswa kwamehlo.

Izaziso kumuthi wakho we-eyeglass

Uma ubheka umuthi wakho we-eyeglass, ungabona izincomo ezithile zelensi ezifakwe udokotela wakho. Lokhu ngokujwayelekile kuyakhethwa futhi kungahle kube nezindleko ezingeziwe:

• Amalensi Photochromic.Futhi okubizwa ngokuthi ngamalensi e-tint aguquguqukayo namalensi akhanyisa ngokukhanya, lokhu kwenza ama-lens abe mnyama ngokuzenzakalela lapho ekhanyiselwa ilanga.
• Ukumboza okuphikisayo.Ebizwa nangokuthi ukugqokiswa kwe-AR noma ukumbozwa kwe-anti-glare, lokhu kumboza kunciphisa ukubonakaliswa ukuze ukukhanya okuningi kudlule kuma-lens.
• Ama-lens aqhubekayo.Lawa amalensi amaningi angenalayini.

Umuthi wakho we-glassglass akuyona incwadi yakho ye-lens yokuxhumana

Ngenkathi umuthi wakho wengilazi yesibuko unalo lonke ulwazi oludingekayo ukuze uthenge izibuko zamehlo, alunalo ulwazi oludingekayo lokuthenga amalensi wokuxhumana.

Lolu lwazi lubandakanya:

• ubukhulu belensi
• ijika lobuso obungemuva belensi yokuxhumana
• umenzi welensi negama lomkhiqizo

Udokotela wakho kwesinye isikhathi uzolungisa inani lamandla okulungisa phakathi kwezibuko namalensi wokuxhumana ngokususelwa ebangeni lens elizobe lisuka kulo iso. Izibuko zicishe zibe ngamamilimitha ayi-12 (mm) ukusuka ebusweni beso ngenkathi amalensi wokuxhumana ngqo ebusweni beso.

Ukudla okudlela endlini

Ngokuya ngesimo sakho esithile - njengamanje usebenzisa izigqoko zamehlo zokulungisa, iminyaka yobudala, izinto ezinobungozi, nokuningi - odokotela abaningi bamehlo baphakamisa ukuthi bahlolwe ngokuphelele unyaka nonyaka noma emibili.

Ngaleso sikhathi, uma kunesidingo, udokotela wakho uzokunikeza incwadi kadokotela ongayisebenzisa lapho uthenga izambatho zamehlo. Lo myalelo ungabonakala udideka uze wazi incazelo yezifinyezo ezifana ne-OS, OD, ne-CYL.

Khumbula ukuthi umuthi owunikezwa izibuko zamehlo akuyona incwadi kadokotela yamalensi wokuxhumana. Awukwazi ukuthola incwadi kadokotela yamalensi wokuxhumana kuze kube yilapho udokotela wakho enze impendulo efanelekile futhi ehlolisisa impendulo yamehlo ekugqokeni ama-lens.
