Kodi magalasi opita patsogolo ndi chiyani?
Ma lens opita patsogolo ndi ma multifocal opanda mizere omwe amakhala ndi kupitilirabe kwamphamvu kwamphamvu yokulirapo yapakati komanso pafupi.
Magalasi opitilira patsogolo (monga ma lens a Varilux) nthawi zambiri amapereka chitonthozo komanso magwiridwe antchito, koma palinso mitundu ina yambiri.Katswiri wanu wa chisamaliro cha maso akhoza kukambirana nanu za mawonekedwe ndi maubwino a magalasi omwe akupita patsogolo ndi kukuthandizani kupeza magalasi abwino kwambiri pazosowa zanu zenizeni.
Mphamvu ya magalasi opita patsogolo imasintha pang'onopang'ono kuchokera kumalo kupita kumalo a lens pamwamba, kupereka mphamvu yoyenera ya lens
kuwona zinthu momveka bwino pamtunda uliwonse.
Komano, ma bifocals ali ndi mphamvu ziwiri zokha za lens - imodzi yowonera zinthu zakutali bwino komanso mphamvu yachiwiri kumunsi.
theka la disolo kuti muwone bwino patali wowerengera.Kulumikizana pakati pa magawo amphamvu awa
amatanthauzidwa ndi "bifocal line" yowoneka yomwe imadutsa pakati pa disolo.
Magalasi opita patsogolo, kumbali ina, ali ndi mphamvu zambiri za lens kuposa ma bifocals kapena trifocals, ndipo pali kusintha kwapang'onopang'ono kwamphamvu kuchokera kumalo kupita kumalo kudutsa pamwamba pa mandala.
* Imawonetsetsa bwino patali (m'malo mongoyang'ana mitu iwiri kapena itatu yokha).
* Imathetsa "kudumpha kwazithunzi" kovutitsa komwe kumachitika chifukwa cha ma bifocals ndi trifocals.Apa ndi pamene zinthu zimasintha mwadzidzidzi momveka bwino komanso powonekera pamene maso anu akuyenda kudutsa mizere yowonekera mu magalasi awa.
* Chifukwa palibe "mizere ya bifocal" yowoneka m'magalasi opita patsogolo, amakupatsirani mawonekedwe achichepere kuposa ma bifocal kapena trifocals.(Chifukwa chake chokha chingakhale chifukwa chake anthu ambiri masiku ano amavala magalasi opita patsogolo kuposa omwe amavala ma bifocal ndi trifocal pamodzi.)

Pewani kuwononga magalasi anu mwachangu kuwateteza kuti asakwande mosavuta | Chepetsani kunyezimira pochotsa kuwunikira kuchokera pamwamba pa mandala kuti asasokonezedwe ndi kupuwala | Pangani pamwamba pa magalasi apamwamba kwambiri a hydrophobic, kukana kwa smudge, anti static, anti scratch, kuwonetsera ndi mafuta. |
