Abantu abaninzi abaye banxiba iiglasi iminyaka
Kusenokubakho ukuthandabuza okunje:
Ukunxiba iiglasi ixesha elide, akucaci ngenene ukuhlelwa kweelensi
I-Myopia kunye ne-hyperopia?Yintoni okugxilwe ngokukodwa kunye nokugxila kwizinto ezininzi?
Isiphukuphuku asikwazi kuthetha umahluko
Ukukhetha iilensi kubhida ngakumbi:
Loluphi uhlobo lwelensi olufanelekileyo kuwe?
Kukho zonke iintlobo zemisebenzi?Zeziphi izinto endizifunayo?
Kukho zonke iintlobo zeelensi;
Ukuba i-lens yahlulwe ukusuka kugxininiso, inokwahlulwa ibe yi-lens egxininisekileyo enye (i-monophoto), i-lens egxininise kabini, i-multifocal lens.
Iilensi ezininzi eziqhubelekayo, ezikwabizwa ngokuba ziilensi eziqhubelekayo, zineendawo zokugxila ezininzi kwilensi.
Namhlanje siza kuthetha malunga ne-multifocal progressive lens
Yintoni i-lens ye-multifocal eqhubekayo?
Iiglasi eziqhubela phambili ze-multifocal, ezineendawo ezininzi zokugxila kwilensi enye ngaxeshanye, ngokuthe ngcembe ziguquka ukusuka kwindawo ekude phezulu kwilensi ukuya kwindawo ekufutshane ezantsi.
Ukuba nedigri ezininzi kwilensi efanayo kwahlulwe ngokwemimandla emithathu: kude, phakathi nakufutshane:
1, umbono ophezulu kwindawo ekude
Isetyenziselwa ukubona umgama omde, njengokudlala, ukuhamba, njl
2, embindini wesithili esiphakathi
Ukubona umgama ophakathi, njengokubukela ikhompyuter, ukubukela iTV, njl
3. Umbono osezantsi okufutshane nendawo
Isetyenziselwa ukujonga ngokusondeleyo, njengokufunda iincwadi, amaphephandaba, njl
Ke ngoko, ukunxiba iiglasi kuphela, kunokwanelisa imfuno ekude, yabona, ubone umbono okufutshane.
Iziganeko eziqhelekileyo zefiziyoloji:
I-Presbyopia, ebonakala ngokuthe ngcembe ngokunyuka kweminyaka, ibonakala ngokubonakalayo njengento engabonakaliyo kwaye ayikwazi ukubona izinto ezikufutshane.Le meko iya kunciphisa ukusebenza kakuhle kwaye ichaphazele umgangatho wobomi.
I-progressive multifocal lens sisisombululo esilungileyo kule ngxaki
Ngomsebenzi ogqwesileyo
Kuthandwa kakhulu kwaye kufunwa emva koko kuluhlu
