Lens ya masomphenya amodzi: Lens yonse ili ndi mphamvu yofananira ndi mankhwala.Amapangidwa kuti akonze vuto la masomphenya monga kuyang'anira pafupi kapena kuyang'ana patali.Imakhala ndi malo amodzi omwe amapereka masomphenya omveka bwino pamtunda wina (pafupi, pakati kapena kutali).
Lens ya Varifocal: Lens imodzi imabwera mu mphamvu zosiyanasiyana zomwe zimaperekedwa kuti ziwongolere pafupi, apakatikati, ndi mtunda.Imakhala ndi kusintha kwapang'onopang'ono kwa mphamvu yamankhwala kuchokera pamwamba mpaka pansi pa disolo, kulola kusintha kosasinthika pakati pa mtunda wowonera.Chifukwa mphamvu ya mankhwala imayenda bwino kuchokera pamwamba mpaka pansi pa lens, amatchedwanso magalasi opita patsogolo.
Ndi iti yomwe ili yabwino masomphenya amodzi kapena multifocal?
Poganizira ngati magalasi a masomphenya amodzi kapena ma multifocal ndi abwino kwa inu, pali zinthu zingapo zomwe muyenera kuziganizira:
∙Zosowa za masomphenya: Ngati mukufunikira kukonza mtundu umodzi wa masomphenya (monga kuyang'ana pafupi kapena kuyang'ana patali), magalasi a maso amodzi ndi abwino.Ma lens a Multifocal ndi oyenerera ngati muli ndi vuto la masomphenya angapo kapena mukufuna kuwongolera masomphenya apafupi ndi mtunda.
∙Kusavuta: Magalasi a masomphenya amodzi amapangitsa kuti zikhale zosavuta kugwira ntchito zinazake, monga kuwerenga kapena kuyendetsa galimoto, chifukwa amakongoletsedwa mtunda umodzi.Komabe, ngati nthawi zambiri mumasinthasintha pakati pa ntchito zowonera pafupi ndi zakutali, ma lens a multifocal amatha kukupatsirani kusintha kosasinthika pakati pa mtunda wosiyanasiyana.
∙Moyo: Ganizirani za moyo wanu ndi zochita za tsiku ndi tsiku.Mwachitsanzo, ngati mumathera nthawi yambiri mukugwira ntchito pakompyuta kapena kuwerenga,magalasi a multifocalzitha kukhala zopindulitsa chifukwa zimatha kuwonetsa bwino pamtunda wosiyanasiyana popanda kusinthana pakati pa magalasi osiyanasiyana.
∙Nthawi Yosintha: Ndikofunikira kudziwa kuti anthu ena angafunike nthawi yosinthira pamene akusintha kupita ku magalasi ambiri, chifukwa izi zimaphatikizapo kusintha kumadera osiyanasiyana.Magalasi a masomphenya amodzi nthawi zambiri sakhala ndi nthawi yosinthayi.
∙Thanzi la Maso: Thanzi la maso anu ndi zovuta zilizonse zitha kukhudzanso kusankha kwanu magalasi amasomphenya amodzi motsutsana ndi ma lens ambiri.Katswiri wanu wosamalira maso atha kukupatsani chitsogozo potengera zosowa zanu zathanzi lamaso.
Mwachidule, kusankha kwabwinoko pakati pa magalasi a masomphenya amodzi ndi ma lens ambiri kumadalira zosowa zanu zamasomphenya, zochita za tsiku ndi tsiku, komanso thanzi la maso.Ndikofunikira kukambirana izi ndi katswiri wosamalira maso kuti adziwe njira yabwino kwa inu.
Kodi ndingadziwe bwanji ngati ndikufunika masomphenya amodzi kapena magalasi opita patsogolo?
Kuti mudziwe ngati mukufunamasomphenya magalasi amodzi or magalasi opita patsogolo,lingalirani zotsatirazi ndikukambirana ndi katswiri wosamalira maso:
∙ Presbyopia: Ngati muli ndi zaka zoposa 40 ndipo mukuvutika kuona zinthu zomwe zili pafupi, mukhoza kukhala ndi presbyopia.Magalasi opita patsogolo amathandiza kuthetsa vuto lokhudzana ndi zaka izi popereka kusintha kosasunthika kuchokera kumawonedwe akutali pamwamba mpaka pafupi ndi masomphenya pansi.
∙ Zosowa zamasomphenya angapo: Ngati muli ndi zosowa zosiyanasiyana za masomphenya patali, apakatikati, ndi pafupi ndi masomphenya, monga kuwerenga, kugwira ntchito pakompyuta, ndi kuyendetsa galimoto, magalasi opita patsogolo amatha kukupatsani masomphenya omveka patali konse popanda kufunikira kosinthira pakati pa magalasi angapo.
∙ Moyo ndi zochita za tsiku ndi tsiku: Ganizirani zochita zanu zatsiku ndi tsiku ndi kuchuluka kwa momwe mumasinthira zinthu zosiyanasiyana zowoneka.Ngati nthawi zambiri mumasintha pakati pa ntchito zowonera pafupi ndi mtunda, magalasi opita patsogolo amatha kukuthandizani komanso kukonza masomphenya mopanda msoko.
∙ Thanzi la Maso: Mikhalidwe ina yathanzi lamaso kapena vuto la masomphenya lingasonyeze kufunikira kwa mitundu ina ya magalasi.Kambiranani za vuto lililonse lamaso ndi katswiri wosamalira maso kuti mudziwe njira zabwino zopangira magalasi pazosowa zanu.
∙ Kukonda ndi chitonthozo: Anthu ena angakonde kumasuka ndi kukongola kwa magalasi opita patsogolo, pamene ena angapeze magalasi a masomphenya amodzi omasuka kwambiri pa ntchito zinazake.
Pamapeto pake, kuyezetsa mwatsatanetsatane kwa maso ndi kukambirana ndi katswiri wosamalira maso kudzakuthandizani kudziwa ngati magalasi a masomphenya amodzi kapena ma lens opita patsogolo ndi abwino kwa zosowa zanu zamasomphenya ndi moyo wanu.Malingana ndi zofunikira zanu zapadera, katswiri wosamalira maso angakulimbikitseni njira zoyenera kwambiri za lens kwa inu.
Inde,masomphenya magalasi amodziakhoza kukonza astigmatism.Astigmatism ndi vuto lodziwikiratu lomwe limayamba chifukwa cha diso losawoneka bwino kapena ma lens mkati mwa diso, zomwe zimapangitsa kusawona bwino kapena kupotoza kutali.Magalasi a masomphenya amodzi amatha kuthana ndi astigmatism pophatikiza mphamvu zowongolera zolipirira kupindika kosakhazikika kwa maso.Pankhani yokonza astigmatism, magalasi a masomphenya amodzi amatha kusinthidwa kukhala momwe amafunikira kuti athetse vuto la refractive lomwe limakhudzana ndi vutoli.Lamuloli limatsimikiziridwa ndi kuyezetsa kwamaso kwatsatanetsatane kochitidwa ndi katswiri wosamalira maso, komwe kumaphatikizapo miyeso yowunika kuchuluka ndi komwe astigmatism ali nayo m'diso lililonse.Malangizo a mandala a maso amodzi kuti akonze astigmatism nthawi zambiri amakhala ndi gawo lamphamvu la cylindrical kuwonjezera pa mphamvu yozungulira.Mphamvu ya Cylinder ndiyofunikira kwambiri pakusintha kwa kupindika kwa cornea kapena lens, kuwonetsetsa kuti kuwala kwatsitsidwa ndikulunjika bwino pa retina.Pophatikizira kuwongolera kwa astigmatism mu kapangidwe ka mandala, magalasi a masomphenya amodzi amatha kubweza bwino kusokoneza komanso kupotoza komwe anthu omwe ali ndi astigmatism amakumana nawo.Ndikoyenera kudziwa kuti magalasi a masomphenya amodzi a astigmatism ndi osinthasintha ndipo amatha kukwaniritsa zosowa zosiyanasiyana za masomphenya, kuphatikizapo mtunda, pafupi, kapena masomphenya apakati.Kaya amagwiritsidwa ntchito ngati magalasi kapena ma lens, magalasiwa ndi oyenerera kwa anthu azaka zonse omwe ali ndi astigmatism, motero amakumana ndi moyo wambiri komanso zofunikira zowonera.Ngati atalembedwa molondola, magalasi a masomphenya amodzi a astigmatism angapereke chitonthozo ndi masomphenya.Pothana ndi kusakhazikika kwa mawonekedwe a diso, magalasi awa amathandizira kuti anthu azitha kuyang'ana bwino, achepetse kutopa kwamaso, komanso kuwongolera mawonekedwe onse.Izi zimathandiza kupereka mawonekedwe omasuka komanso okhutiritsa kwa iwo omwe amadalira magalasi a masomphenya amodzi kuti akonze astigmatism.Mwachidule, magalasi a masomphenya amodzi amatha kukonza astigmatism mwa kuphatikiza mankhwala osinthidwa omwe amaganizira cholakwika cha refractive chokhudzana ndi astigmatism.Popereka kuwongolera makonda, magalasi awa adapangidwa kuti aziwona bwino anthu omwe ali ndi astigmatism ndikuwongolera mawonekedwe onse.
