Anthu omwe amakonda kusintha fano lawo, ndipo amamvetsera ngakhale zochepa kwambiri pachithunzichi, nthawi zambiri amakhala ndi malingaliro amodzi. Chalk izi zing'onozing'ono zimakulolani kusindikiza kapena kusintha kwambiri mthunzi wa chilengedwe cha iris, kuti uupatse kuyang'ana kodabwitsa ndi kodabwitsa chifukwa cha mitundu yosiyanasiyana. Kuwonjezera pamenepo, zipangizozi zingagwiritsidwe ntchito powonetsera masomphenya .
Kodi makalenseni amatha bwanji?
Kuti mupeze zipangizo zangwiro, nkofunika kuti muwerenge mosamala makhalidwe awo akuluakulu.
Choyamba muyenera kudziwa zomwe mukupanga. Pali magulu awiri akuluakulu omwe amafotokozedwa - zipangizo zamakono zofiira komanso zofewa. Mankhwala osokoneza bongo oposa 90 peresenti ndi amodzi omwe amapangidwa kuchokera ku hydrogel kapena silicone hydrogel . Zida zochepa zimapangidwa kuchokera ku ma polima apadera, zomwe zimalangizidwa kuti zikonzeko mitundu yosiyanasiyana ya astigmatism ndi keratoconus.
Gawo lotsatiralo la kusankha mandala kumaphatikizapo kusankha mtundu wawo ndi kukwaniritsa. Pali mitundu yambiri yofotokozedwa ndi zipangizo:
- kutulutsa;
- kudula chikhalidwe chachilengedwe cha iris;
- "Wopenga" kapena zikondwerero.
Mtundu woyamba wa zipangizozo ndi woyenera kwambiri kwa maso owala. Zimakupatsani inu mthunzi wachilengedwe wa iris mwakuya ndi wokhutira kwambiri, koma musasinthe kwambiri.
Kuti mukhale ndi maso a mdima, malingaliro a mtundu wa makina ndi mtundu wosanjikiza wa pigment akulimbikitsidwa. Amapereka kusintha kwa mthunzi uliwonse wa iris kwa tanthauzo lofunikila.
Zipangizo zamakono zimagwiritsidwa ntchito popanga zithunzi pazithunzi zazithunzi, maphwando odyetserako, zikondwerero zomwe zimagulitsidwa. Zida monga "wopenga" zimasiyanitsidwa ndi mitundu yosiyanasiyana yodabwitsa komanso mithunzi yonyansa. Ndi chithandizo chawo, mukhoza kusintha mtundu wa sclera.
Chinthu china chofunika kwambiri pakusankha ma lenseni ndi nthawi yomwe amasintha. Pali nthawi zingapo zoyenera kuzivala:
- tsiku;
- Masabata 1-2;
- mwezi;
- mpaka miyezi isanu ndi umodzi;
- Miyezi 12 (mwambo).
Tiyenera kuzindikira kuti ngakhale mtundu wabwino kwambiri wothandizana ndi makina osakanizidwa siwotchulidwa kuti ugwiritsidwe ntchito nthawi ndi nthawi. Ophthalmologists akulangizidwa kuti asavale kawiri kawiri pamlungu maola angapo, makamaka masana. Zoona zake n'zakuti madzulo ndipo osaphunzira mokwanira, wophunzirayo amalongosola, motero, gawo lachikuda lazowonjezera limalowa mu masomphenya, omwe amavomereza ndi ubongo ngati kusokoneza maso.
Makina ojambulira okongola omwe ali ndi diopters
Kawirikawiri, zipangizo zowonetsera zimapangidwa mumthunzi wa mthunzi, chifukwa mawonekedwe awo amatha kuzindikira bwinobwino ngakhale kuti akukula kapena kuponderezedwa kwa wophunzira komanso popanda kusokoneza.
Mitundu ina yamalonda achikuda ndi diopters ndi yosavomerezeka, ngakhale iyenso imafunikira. Akatswiri samalimbikitsa kugwiritsa ntchito zipangizo zogwiritsira ntchito za iris ndi zomangamanga za dongosololi nthawi ndi nthawi. Chilolezo chololedwa ndi 2-4 maola, 1-2 nthawi
Lensulo zamagetsi popanda ma diopter kwa maso
Ngati palibe vuto ndi masomphenya, palibe malire apadera pa nthawi yogwiritsira ntchito mapulogalamu opanga mapepala, mapiritsi kapena ophunzira.
Chinthu chachikulu ndicho kugula zipangizo zamtengo wapatali ndi mafuta okwanira okwanira ndi madzi okwanira (pafupifupi 70%). Izi zimapereka mwayi waufulu wopeza mpweya kwa diso, komanso kumapangitsa kuti diso likhale lopanda mphamvu, lomwe limapangitsa kuti munthu asakhumudwitse komanso kupweteka pamene akuvala ma lens.
