Kusiyana pakati pa masomphenya amodzi ndi ma lens a bifocal: kusanthula kwathunthu

Magalasi akuluakulu m'masolo akonzedwe ndikubwera m'mitundu yosiyanasiyana kutengera zosowa zenizeni za wovalayo. Awiri mwa magalasi omwe amagwiritsidwa ntchito kwambiri ndimagalasi amodzindima lees a bifocal. Pomwe onse akutumikirabe kuwonongeka koyenera, adapangidwira zolinga ndi anthu. Kuzindikira kusiyana pakati pa magalasi amenewa ndikofunikira kuti mupange kusankha mwanzeru, makamaka ngati masomphenya a anthu amafunikira kusintha kwa zaka komanso moyo wake. Mu kusanthula mwatsatanetsatane, tiwona kusiyana pakati pa masomphenya amodzi ndi mandala a bifocal, kuphatikiza mapulogalamu awo, mapindu ake, komanso momwe amathetsera mavuto.

1. Magalasi amodzi: ndi chiyani?

Mitundu imodzi yamaso ndi mtundu wosavuta kwambiri komanso wogwiritsidwa ntchito kwambiri wa mandala ambiri m'maso. Monga momwe dzinalo limanenera, magalasi amenewa adapangidwa kuti azitha kusintha masomphenya amodzi. Izi zikutanthauza kuti ali ndi mphamvu zofananira zomwezo padziko lonse lapansi, ndikuwapangitsa kukhala oyenera kuyankha mtundu wina wa vuto lokonzansoKukongola (Myepia)kapenaMatendawa (hyperopia).

Zofunikira:

• Mphamvu yunifolomu: Mandala ali ndi mphamvu ya mankhwala ogwirizana, kuyang'ana pamawu amodzi pa retina. Izi zimathandiza kuti masomphenya owoneka bwino patali kamodzi.
• Zogwirizanitsidwa: Chifukwa magalasi osakwatiwa amalondola chifukwa cha vuto limodzi lokha la masomphenya, ndi owongoka popanga ndi kupanga.
• Kwa Myopia (Kusirira): Omwe ali ndi pheesing alibe vuto kuwona zinthu zakunja momveka bwino. Magalasi amodzi a kugwirira ntchito mozama pobalalitsa nthawi isanakwane retina, kuthandiza zinthu zakunja kuwonekera.
• Kwa hypepia (tarsadenness): Anthu omwe ali ndi chidwi ndi vuto lolimba kuti awone bwino zinthu zapafupi. Malingaliro amodzi a hyperopia amayang'ana kwambiri pa retina, omwe amakumana ndi masomphenya.

Gwiritsani ntchito milandu:

Magalasi amodzi omwe amathanso kugwiritsidwa ntchito kwa anthu omwe ali ndi Astigmatism, mkhalidwe womwe chimapangidwa ndi ziphuphu zakunja, chimapangitsa kuti pakhale masomphenya patali patali. Mauna ang'onoang'ono amasomagalasi a mafutiamapangidwa kuti akonzekere ku Adiogmatism.

Ubwino wa magalasi amodzi:

1. Kupanga kosavuta ndi kupanga: Chifukwa mandala awa amapangidwa kuti azitha kusintha masomphenya mtunda umodzi wokha, ndiwosavuta komanso wotsika mtengo kuti zipatso zambiri zitheke kuposa ma lenifilocal.
2. Mapulogalamu osiyanasiyana: Mauna amodzi omwe amawoneka bwino komanso oyenera kwa anthu azaka zonse omwe ali ndi vuto lolakwika lokha.
3. Mtengo wotsika: Nthawi zambiri, magalasi amodzi m'masondi ali otsika mtengo kuposa mandala kapena opita patsogolo.
4. Kusintha kosavuta: Chifukwa mandala onse ndi yunifolomu mu mphamvu yake yokonza, oonda magalasi amodzi amasinthana mosavuta popanda kusokonekera kapena kusasangalala kulikonse.
5. Mitundu Yochepera: Magalasi amodzi omwe amangoganiza za vuto limodzi la masomphenya (pafupi kapena kutali), zomwe zingakhale zosakwanira kwa anthu omwe amakulitsa kwa anthu omwe amakhudza masomphenya onse pafupi ndi masomphenya onse.
6. Kusintha kwamaso pafupipafupi: Kwa anthu omwe amafuna kuwongolera mtunda ndi ntchito zapamwamba (mwachitsanzo, kuwerenga ndi kuyendetsa), magalasi amodzi m'masondi angathandize kusintha pakati pa magalasi osiyanasiyana, omwe angakhale ovuta.

2. Ma lembo a Biocal: Ndi chiyani?

Mauna a Biocal amapangidwira makamaka kwa anthu omwe akufuna kuwongolera onseMasomphenya a mtundandiPafupi ndi masomphenya. Magalasi awa agawidwa m'magawo awiri apadera: gawo limodzi kuti muwone zinthu zakunja momveka bwino, pomwe winayo ndi wa kuona zinthu zapafupi, monga kuwerenga. Ma bifocdals adapangidwa mwamwambo kuti athe kuyankhaPresByARE, mkhalidwe womwe diso limataya luso lake kuyang'ana pa zinthu zapafupi monga zaka.

• Mzere wogawana: Mabino achikhalidwe amakhala ndi mzere kapena kupindika zomwe zimalekanitsa magawo awiriwa, zimapangitsa kuti zisinthe pakati pa mtunda ndi kuwerenga zomwe zimangowerenga.
• Kwa PresBopia: Chifukwa chofala kwambiri chomwe anthu amavala mandala a bitocal ndikuwongolera Presbopia. Makhalidwe okhudzana ndi zaka izi amayamba kukhudza anthu m'ma 40s ndi 50s, zomwe zimapangitsa kuti zikhale zovuta kuyang'ana pa zinthu zapafupi, monga kuwerenga kapena kugwiritsa ntchito foni yam'manja.
• Kuwongolera munthawi yomweyo: Ma bifocles ndi abwino kwa anthu omwe amafunikira kusintha pafupipafupi pakati pakuwona zinthu zakutali (monga poyendetsa TV) ndikuziwerenga kapena kugwiritsa ntchito kompyuta). Mapangidwe awiri-amodzi amalola kuti achite izi popanda kusintha magalasi.

Gwiritsani ntchito milandu:

Ubwino wa Ma lens a Biocal:

1. Yankho losavuta: Ma bifo amachotsa kufunika konyamula magalasi ambiri. Pophatikiza mtunda ndi kufupikitsa kwa masomphenyawo mu chidutswa chimodzi, amapereka yankho lothandiza kwa iwo omwe ali ndi Presboopia kapena zosowa zina zamakono zofananira.
2. Ntchito Yabwino Kwambiri: Kwa anthu omwe amafunikira masomphenya owonekera kutali kwambiri komanso pafupi, mabisi amabisi amapereka kusintha komwe kumachitika tsiku lililonse popanda zovuta.
