Malenzi eRGP anogadzirwa nezvinhu zvepurasitiki zvinochinjika izvo zvinowanzo sanganisira silicone.Ichi chinhu chisina kuremerwa chinobvumira okisijeni kuti ipfuure yakananga nelenzi ichienda kucornea yeziso rako.
Ziso rako ndiro rakaonekera kunze kwekunze kweziso rako. Cornea yako inoramba chiedza uye inoita seyekunze yeziso rako. Kana ziso rako rikasawana oxygen yakakwana, rinozvimba. Izvi zvinogona kukonzera kusaona zvakanaka kana kusaona zvakanaka, uyewo mamwe matambudziko emaziso.
Malenzi ePMMA haatenderi kuti okisijeni ipfuure nepakati pemalenzi.Nzira chete iyo okisijeni inogona kusvika pacornea ndeye kana misodzi ichiyerera pasi pelenzi pese paunobwaira.
Kuti ubvumire misodzi kufamba pasi pe lens, PMMA lenses idiki zvishoma muhukuru.Uye, panofanira kuva nemukaha pakati pe lens uye cornea.Izvi zvinoita kuti PMMA lenzi dzive dzisina kugadzikana kupfeka, uye lenzi dzinowanzobuda kunze. , kunyanya pakuita maekisesaizi.
Nekuti maRGP lenzi anobvumira okisijeni kuti ipfuure nepakati pavo, malenzi aya akakura kupfuura PMMA lenzi uye anovhara zvakanyanya ziso.
