Magalasi a Bifocal ndi magalasi apadera opangidwa kuti akwaniritse zosowa za anthu omwe amavutika kuyang'ana zinthu zapafupi ndi zakutali.Zotsatirazi ndi mfundo zazikuluzikulu zomwe muyenera kuziganizira mukamagwiritsa ntchito magalasi a bifocal:
Kukonzekera kwa Presbyopia:Magalasi a Bifocal amagwiritsidwa ntchito kukonza presbyopia, cholakwika chokhudzana ndi zaka zomwe zimakhudza kuthekera kwa diso kuyang'ana zinthu zomwe zili pafupi.Matendawa nthawi zambiri amawonekera pafupi ndi zaka 40 ndipo amachititsa kuti munthu azivutika kuwerenga, pogwiritsa ntchito zipangizo zamakono komanso ntchito zina zapafupi.
Kuwongolera masomphenya awiri:Magalasi a Bifocal ali ndi mphamvu ziwiri zosiyana za kuwala mu lens imodzi.Kumtunda kwa mandala kumapangidwa makamaka kukonza masomphenya akutali, pomwe gawo lapansi lili ndi diopter yowonjezera yowonera pafupi.Mankhwala apawiri awa amalola odwala presbyopic kukhala ndi magalasi kuti akwaniritse zosowa zawo zamasomphenya patali kosiyana.
Kusintha kosasunthika:Mapangidwe a magalasi a bifocal amalola kusintha kosasinthika pakati pa magawo apamwamba ndi apansi a mandala.Kusintha kosalala kumeneku ndikofunikira kuti mukhale womasuka komanso wowoneka bwino mukasinthana pakati pa zochitika zomwe zimafunikira kuyang'ana pafupi ndi mtunda.
Kusavuta komanso kusinthasintha:Magalasi a Bifocal amapereka mwayi komanso kusinthasintha kwa anthu omwe ali ndi presbyopia popereka njira yowonera pafupi ndi patali mu magalasi amodzi.M'malo mosinthasintha nthawi zonse pakati pa magalasi angapo, ogwiritsa ntchito amatha kudalira ma bifocals pa ntchito zosiyanasiyana ndi zochitika, monga kuwerenga, kuyendetsa galimoto, kugwira ntchito pakompyuta, ndi zokonda zomwe zimakhudza kuyang'ana pafupi kapena kutali.
Kugwiritsa ntchito:Magalasi a Bifocal nthawi zambiri amakhala oyenera anthu omwe ntchito zawo kapena zochitika za tsiku ndi tsiku zimafuna kusintha pafupipafupi pakati pa pafupi ndi mtunda.Izi zikuphatikiza ntchito monga othandizira azaumoyo, ophunzitsa, amakanika, ndi akatswiri ojambula, pomwe masomphenya omveka bwino akutali ndi ofunikira kuti agwire bwino ntchito ndi chitetezo.
Zokonda pazofuna zapayekha: Magalasi a Bifocal amatha kusinthidwa kuti akwaniritse zofunikira za munthu aliyense.Madokotala a maso ndi ophthalmologists amawunika mosamala zomwe wodwala amawona komanso momwe amakhalira ndi moyo wake kuti adziwe momwe magalasi amawonekedwe oyenera a bifocal, kuwonetsetsa kuti mankhwalawo akukwaniritsa zosowa za ntchito yawo ndi zosangalatsa.
Pang'onopang'ono sinthani ku:Kwa ovala magalasi atsopano a bifocal, pali nthawi yosintha kuti maso agwirizane ndi magalasi a bifocal.Odwala atha kukumana ndi zovuta zosinthira kuzinthu zosiyanasiyana zomwe zili mkati mwa mandala, koma pakapita nthawi ndi chizolowezi, anthu ambiri amazolowerana bwino ndikusangalala ndi ubwino wowona bwino pafupi ndi patali.
Pomaliza, magalasi a bifocal ndi ofunikira kuthana ndi zovuta zamasomphenya zomwe zimaperekedwa ndi presbyopia.Mapangidwe awo amitundu iwiri, kusintha kosasunthika, kusavuta, kusinthasintha, ndi kuthekera kosintha mwamakonda kumawapangitsa kukhala yankho labwino kwa anthu omwe akufuna kuwona bwino komanso omasuka mtunda wosiyanasiyana pamoyo wawo watsiku ndi tsiku.
Ndani ayenera kuvala bifocals?
Magalasi a Bifocal nthawi zambiri amaperekedwa kwa anthu omwe ali ndi presbyopia, matenda okhudzana ndi msinkhu omwe amachititsa kuti diso lizitha kuyang'ana zinthu zomwe zili pafupi chifukwa cha kuwonongeka kwa chilengedwe kwa lens ya diso.Presbyopia nthawi zambiri imawonekera mwa anthu azaka zopitilira 40, zomwe zimapangitsa kuti azivutika kuwerenga, kugwiritsa ntchito zida za digito, ndikuchita ntchito zina zapafupi.Kuphatikiza pa presbyopia yokhudzana ndi zaka, magalasi a bifocal amathanso kulimbikitsidwa kwa anthu omwe amayang'anizana ndi zovuta zakutali komanso pafupi ndi masomphenya chifukwa cha zolakwika zina monga kuona patali kapena myopia.Chifukwa chake, magalasi a bifocal amapereka yankho losavuta kwa anthu omwe amafunikira mphamvu zosiyanasiyana zowonera kuti akwaniritse zosowa zawo zamasomphenya kutali.
Ndi liti pamene muyenera kuvala bifocals?
Magalasi a Bifocal nthawi zambiri amalimbikitsidwa kwa anthu omwe amavutika kuona zinthu zapafupi chifukwa cha presbyopia, kukalamba kwachilengedwe komwe kumakhudza mphamvu ya maso kuyang'ana zinthu zomwe zili pafupi.Matendawa nthawi zambiri amawonekera ali ndi zaka 40 ndipo amakula pakapita nthawi.Presbyopia ingayambitse zizindikiro monga kupsinjika kwa maso, kupweteka mutu, kusawona bwino komanso kuvutika kuwerenga zolemba zazing'ono.Magalasi a Bifocal amathanso kupindulitsa anthu omwe ali ndi zolakwika zina, monga kuwonera pafupi kapena kuyang'ana patali, komanso omwe amafunikira mphamvu zosiyanasiyana zowunikira kuti aziwona pafupi ndi patali.Ngati mupeza kuti nthawi zambiri mumakhala patali ndi zomwe mukuwerenga, mumakumana ndi vuto lamaso powerenga kapena kugwiritsa ntchito zida zamagetsi, kapena mukufunika kuchotsa magalasi kuti muwone zinthu pafupi, ingakhale nthawi yoganizira ma bifocals.Kuonjezera apo, ngati mumavala kale magalasi kuti muone kutali koma mukupeza kuti mukuvutika ndi ntchito zapafupi, ma bifocals amatha kukupatsani yankho losavuta.Pamapeto pake, ngati muli ndi vuto ndi masomphenya apafupi kapena zimakuvutani kusinthana pakati pa magalasi angapo kuti muzichita zinthu zosiyanasiyana, kukambirana za bifocals ndi katswiri wosamalira maso kungakuthandizeni kudziwa ngati ndi chisankho choyenera pazosowa zanu zamasomphenya.
Kodi pali kusiyana kotani pakati pa ma bifocals ndi ma lens okhazikika?
Ma bifocals ndi ma lens okhazikika ndi mitundu yonse ya magalasi agalasi omwe amagwira ntchito zosiyanasiyana ndikukwaniritsa zosowa zosiyanasiyana za masomphenya.Kumvetsetsa kusiyana pakati pa mitundu iwiriyi ya magalasi kungathandize anthu kupanga zisankho zanzeru pazakusintha masomphenya.
Magalasi wamba: Ma lens okhazikika, omwe amatchedwanso ma single vision lens, adapangidwa kuti akonze cholakwika chapadera, monga kuwona pafupi, kuwona patali, kapena astigmatism.Magalasiwa ali ndi mphamvu zofananira ndi dotolo padziko lonse lapansi ndipo amapangidwa kuti aziwoneka bwino pamtunda umodzi, kaya pafupi, pakati, kapena patali.Anthu amene amaona chapafupi angapindule ndi magalasi amene anapatsidwa ndi dokotala amene amawathandiza kuona bwinobwino zinthu zakutali, pamene anthu amene amaona patali angafunikire magalasi kuti aziona bwino.Kuphatikiza apo, anthu omwe ali ndi astigmatism amafunikira magalasi kuti athandizire kupindika kosakhazikika kwa cornea kapena lens ya diso, kuwalola kuyang'ana bwino pa retina.
Ma lens a Bifocal: Ma lens a Bifocal ndi apadera chifukwa amakhala ndi mphamvu ziwiri zosiyana mkati mwa mandala amodzi.Magalasi amapangidwa kuti athetse vuto la presbyopia, mkhalidwe wokhudzana ndi zaka zomwe zimakhudza kuthekera kwa diso kuyang'ana zinthu zomwe zili pafupi.Tikamakalamba, disolo lachilengedwe la diso limakhala losavuta kusinthasintha, zomwe zimapangitsa kuti zikhale zovuta kuyang'ana ntchito zapafupi monga kuwerenga, kugwiritsa ntchito foni yamakono, kapena kugwira ntchito zambiri.Mapangidwe a magalasi a bifocal amaphatikizapo mzere wowonekera womwe umalekanitsa mbali zakumwamba ndi zapansi za mandala.Kumtunda kwa mandala nthawi zambiri kumagwiritsidwa ntchito poyang'ana patali, pomwe kumunsi kumakhala ndi mphamvu zapadera zowonera pafupi.Mapangidwe amagetsi apawiriwa amalola ovala kuti aziwona bwino pamtunda wosiyanasiyana popanda kusinthana pakati pa magalasi angapo.Magalasi a Bifocal amapereka yankho losavuta komanso losunthika kwa anthu omwe amafunikira kuwongolera masomphenya pantchito zapafupi komanso zapamtunda.
Kusiyana kwakukulu: Kusiyana kwakukulu pakati pa magalasi a bifocal ndi ma lens okhazikika ndi kapangidwe kake ndi kagwiritsidwe ntchito komwe akufuna.Magalasi okhazikika amawongolera zolakwika zinazake ndipo amapereka maso patali patali, pomwe magalasi a bifocal amapangidwa kuti agwirizane ndi presbyopia ndikupereka kuwongolera kwa biphoto kuti muwone pafupi ndi patali.Magalasi okhazikika amagwiritsidwa ntchito kuwongolera kuyang'anira pafupi, kuyang'ana patali, ndi astigmatism, pomwe magalasi a bifocal amapereka maso omveka patali kwambiri pophatikiza mphamvu ziwiri zoperekedwa ndi dokotala mu lens imodzi.Mwachidule, magalasi anthawi zonse amakhala ndi vuto linalake la refractive ndikupereka kuwongolera masomphenya amodzi, pomwe magalasi a bifocal amapangidwa kuti athane ndi presbyopia ndikupereka yankho la bifocal pakuwona pafupi ndi mtunda.Kumvetsetsa kusiyana pakati pa mitundu iwiri ya magalasi kungathandize anthu kusankha njira yoyenera yowongolera masomphenya malinga ndi zosowa zawo ndi zomwe amakonda.
