Umahluko phakathi kombono omnye kunye neelensi ze-bifocal: uhlalutyo olubanzi

I-lenses yinto ebaluleke kakhulu ekuboneni umbono kwaye ize ngeendlela ezahlukeneyo ngokuxhomekeke kwiimfuno ezithile zobuthathaka. Ezimbini zeyona len isetyenziswa kakhuluI-lenses yombonokwayeI-Bifocal Lenses. Ngelixa bobabini basebenza ekulungiseleleni impatho-nkqubela, bayilelwe iinjongo ezahlukeneyo kunye nabantu. Ukuqonda umahluko phakathi kwezi zenzo kubalulekile ekwenzeni ukhetho olunolwazi, ngakumbi njengoko umbono wabantu ufuna utshintsho kunye nobudala kunye neendlela zokuphila. Kolu hlalutyo oluneenkcukacha, siya kuphonononga umahluko phakathi kombono omnye kunye neelensi ze-bibulal, kubandakanya izibonelelo zazo, kunye nendlela abajonga ngayo iingxaki ezithile zombono.

1. I-lensey yombono: zithini?

I-lenses yombono ye-lelses yeyona ndlela ilula kwaye isetyenziswa kakhulu i-lens kwiiglasi zamehlo. Njengoko igama libonisa, ezi lelo zenzelwe ukulungisa umbono kubude obujolise kuyo. Oku kuthetha ukuba banegunya elifanayo lokulungisa wonke umphezulu welensi, bebenza balungele ukujongana nohlobo olunye lwempazamo ehlaziyiweyo-nokubaI-Nears (iMyopia)okanyeI-sursicy (i-hyperopia).

Ezona mpawu:

• Amandla E-Iyunifom: Ilensi inamazwe aguqukayo ahlukileyo, egxile ukukhanya kwindawo enye kwi-retina. Oku kuvumela umbono ocacileyo kumgama omnye.
• Ukusebenza kakuhle: Ngenxa yokuba umbono omnye ofanelekileyo uchanekile kuphela uhlobo lwengxaki yombono, bathe ngqo kuyilo kunye nemveliso.
• I-Myopia (i-nears): Abo banobuqili banengxaki yokubona izinto ezikude ngokucacileyo. I-lenses yombono ye-norsed ngokusasazeka ngokusasaza ukukhanya ngaphambi kokuba ibethe i-retina, incedisa izinto ezikude zivele zibukhali.
• Ye-hyperopia (i-farks): Abantu abanoxinzelelo bayasokola ukuze babone izinto ezikufutshane. I-lenses yombono ye-hyperopia igxile kakhulu kwi-retina, ekwandiseni umbono kufutshane.

Sebenzisa iimeko:

I-lensey yombono enye inokusetyenziselwa abantu abane-atightismatism, imeko apho i-cenea yeliso ifakwe ngokungahambelaniyo, ekhokelela kumbono ogqwethekileyo kuwo wonke umgama. I-lenses eyodwa yombono ebizwa ngokuba yiyoI-TOORIC lensesbanikwe i-atigmatism.

IINGXAKI ZEEMPAWU ZOKUXELISA:

1. Uyilo olulula kunye nemveliso: Kungenxa yokuba ezi lelo zenzelwe ukulungisa umbono mgama nje omnye, zilula kwaye zibiza kakhulu ukuvelisa iilensi ze-Mulkocial.
2. Uluhlu olubanzi lwezicelo: I-lenses yombono enye iguquguqukayo kwaye ilungele abantu bayo yonke iminyaka yohlobo olunye lwempazamo.
3. Ixabiso eliphantsi: Ngokubanzi, iilensi zombono ezingenalo zifikeleleke ngakumbi kune-biifocal okanye iilensi zenkqubela phambili.
4. Ukulungelelaniswa ngokulula: Kungenxa yokuba zonke iilensi ziyinto efanayo kumandla ayo achanekileyo, ababuthi belenses engatshatanga baziqhelanisa ngokulula ngaphandle kokufumana nayiphi na imbambano okanye ukungalunganga.
5. Uluhlu lokujonga ukugxila: I-lenses eyodwa yombono ilungisa uhlobo olunye lwengxaki yombono (kufutshane okanye kude), enokungakwaneli ukuba abantu abaphuhlisayo basePrestoopia okanye ezinye iimeko ezinxulumene nobudala ezichaphazela zombini umbono osondeleyo nosekude.
6. Utshintsho olungaguqukiyo: Kubantu abafuna ukulungiswa kwemisebenzi yomgama kunye nemisebenzi evalelweyo (umz, ukufunda nokuqhuba), iilensi zombono enye zinokunyanzelisa ukutshintshela phakathi kweeglasi ezahlukeneyo, ezinokuba zinokukhalazekisa.

UKUHLAZIYWA KWEEMPAWU ZOKUXELISA:

2. I-Bifocal Lenses: Bantoni?

I-lenses ye-Bifocal yenzelwe ngokukodwa abantu abafuna ukulungiswa kokubiniUmbono womgamakwayekufutshane nombono. Ezi lens zahlulahlulwe zangamacandelo amabini ahlukileyo: Inxalenye enye kukubona izinto ezikude ngokucacileyo, ngelixa enye yeyokubona izinto ezisondeleyo, ezinjenge xa ​​ufunda. I-Bifocials ibizimisele ngokwesiko ukuba ilungisweI-Presbyopia, imeko apho iliso liphulukene khona nokukwazi ukugxila kwizinto ezisondeleyo njengabantu.

 Ezona mpawu:

• Imigqaliselo emibini kwilensi enye: Iilensi ze-Bifocal zinamandla amabini ahlukeneyo kwilensi enye, idla ngokwahlukaniswe ngumgca obonakalayo. Inxalenye ephezulu yelensi isetyenziselwa umbono womgama, ngelixa icandelo eliphantsi lisetyenziselwa ukufunda okanye eminye imisebenzi kufutshane.
• Umgca wokwahlulahlulahlulahlula: I-BifoCal yendabuko inomgca okanye ijika eyahlulahlula imimandla emibini yombono, esenza kube lula ukutshintsha phakathi komgama kunye nemigqaliselo yokufunda ngokususa amehlo phezulu okanye ezantsi.
• Ye-presbyopiaEsona sizathu siqhelekileyo abantu banxiba iilensi ze-bifocal zeyokulungisa iPrestogoopia. Le meko inxulumene nobudala idla ngokuqala ukuchaphazela abantu abangama-40s kunye ne-50s, besenza ukuba kube nzima kubo ukugxila kwizinto ezikufutshane, ezinjenge xa ​​kufunda okanye ukusebenzisa i-smartphone.
• Ngombono wombono ngaxeshanye: Iibhayila zilungele abantu abafuna ukutshintsha rhoqo phakathi kokujonga izinto ezikude (njengokuqhuba okanye ukubukela imisebenzi) kunye nokufunda okanye ukusebenzisa ikhompyuter). Uyilo olune-intanethi lubavumela ukuba benze oku ngaphandle kokutshintsha iiglasi.

Sebenzisa iimeko:

IINGXAKI ZOKUGQIBELA ZE-BIFOCAL:

1. Isisombululo esinezibini ezinesibini: Ii-bifucals zisusa isidingo sokuthwala izibini ezininzi zeglasi. Ngokudibanisa umgama kunye nokujonga umbono kwisibini esinye, banikezela ngesisombululo esisebenzayo kwabo bakwiPressopia okanye abanye abafuna umbono ogxile kwi-Muremiopia.
2. Umsebenzi oPhucukileyo: Kubantu abafuna umbono ocacileyo kuwo omabini umgama kunye noluhlu olusondeleyo, iibhastile zibonelela ngokuphuculwa kwangoko kwemihla ngemihla ngaphandle kwengxaki yokugcina iiglasi.
3. Xa kuthelekiswa neendleko zokuqhubela phambili: Ngelixa i-lenses ye-Bifocal ibiza kakhulu kune-lenses enye yombono, ifikeleleke ngakumbi kuneilensi eqhubekayo, ezibonelela ngotshintsho olunemifanekiso phakathi kweendawo ezahlukeneyo zokugxila.
4. Isahlulo esibonakalayo: Elinye lawona manqaku abonakalayo kwiilensi ze-biifocal ngumgca obonakalayo owahlulahlula iindawo ezimbini zombono. Abanye abasebenzisi bafumana le nto i-aesthetivey, kwaye inokwenza isiphumo "segxuso" xa sitshintshela phakathi kweendawo ezimbini.
5. Umbono ophakathi ophakathi: Ngokungafaniyo neelensi zenkqubela phambili, ii-biifocals zinemimandla emibini kagqirha kuphela kunye nekufuphi. Oku kushiya umsantsa wombono ophakathi, njengokujonga isikrini sekhompyuter, esinokuba yingxaki kwimisebenzi ethile.
6. Ixesha lokuhlengahlengiswaAbanye abasebenzisi banokuthatha ixesha ukuba bahlengahlengise utshintsho olukhawulezileyo phakathi kwemimandla emibini, ngakumbi xa utshintshile phakathi komgama kunye nombono kufutshane.

Ukunqongophala kwee-lenses ze-Bifocal:

3. Thelekisa ngokweenkcukacha phakathi kombono omnye kunye neelensi zebiigocal

Ukuqonda ngcono umahluko ophambili phakathi kombono omnye kunye neelensi zebibula, masiphule ukungafani kwabo ngokwemigaqo yoyilo, umsebenzi, kunye namava abasebenzisi.

4. Ufanele ukhethe nini umbono omnye okanye iilensi zebibula?

Ukukhetha phakathi kombono omnye kunye neelensi ze-biifocal ikakhulu kuxhomekeke kwimbono yakho ethile. Nazi ezinye iimeko apho uhlobo ngalunye lusenokuba lukhetho olungcono:

Ukukhetha i-lenses yombono enye:

• Abantu abanomdla okanye abanolwazi: Ukuba unesihlobo esinye kuphela sempazamo yokuphikisana, njengeMyopia okanye i-hyperopia, kwaye awufuni ukulungiswa koombono osondeleyo kunye nombono womgama, iilensi zombono ze-len.
• Abantu abancinci: Abantu abancinci ngokubanzi bafuna kuphela ukulungiswa ngohlobo olunye lwento yokujonga umbono. Kuba bancinci ekunokwenzeka ukuba bamave amava aseTestapia, iilensi zombono omnye zinika isisombululo esilula nesineendleko.
• I-Persogoopia enxulumene nobudala: Ukuba ufumana ubunzima obugxile kwizinto ezisondeleyo ngenxa yePressopia kodwa isafuna ukulungiswa komgama, iilensi ze-bifucal zilukhetho olusebenzayo.
• Ukutshintshela rhoqo phakathi kosondele kwaye kube kude: Kubantu abafuna ukutshintsha rhoqo phakathi kokujonga izinto ezikude nokufunda okanye ukwenza imisebenzi esondeleyo, iilensi zebhasi zibonelela ngokulula kunye nokusebenza kwilensi enye.

Ukukhetha iilensi ze-Bifocal:

5. Ukuqukumbela

Isishwankathelo, iilensi zombono enye kunye neelensi ze-bifucal zenzelwe ukuhlangabezana neemfuno zombono ezahlukeneyo. I-lensey yombono enye ichanile kwaye ilungele abantu abancinci okanye abo bafuna ukulungisa uhlobo olunye lomphumo wombono, njengokungathandekiyo okanye ukubaluleka. I-Bifocal Lenses, kwelinye icala, zilungiselelwe abantu abadala abane-Pressovoopia abafuna ukulungiswa kweso sisombululo sisondele kwaye bade banike isisombululo esifanelekileyo esibini.

Ukukhetha iilensi ezifanelekileyo linyathelo elibalulekileyo ekuqinisekiseni umbono olungileyo wezempilo kunye nentuthuzelo yemihla ngemihla. Ukubonisana ne-optometrist okanye i-overe ye-Of Treance icetyiswa kakhulu ukufumanisa ukuba loluphi uhlobo lweelensi ezifanelekileyo ezifanelekileyo iimfuno zakho.
