Ahakoa he pai ake te maha o ngā karaihe whakapā hydrogel, kāore i te pai te uruhanga o te hāora ki roto. Mai i te hydrogel ki te silicone hydrogel, ka taea te kī he pikinga kounga kua tutuki. Nō reira, hei kanohi whakapā pai rawa atu i tēnei wā, he aha te pai o te silicone hydrogel?
He rauemi pūmua waro tino pai te silicone hydrogel, he nui te uruhanga hāora. Mai i te tirohanga hauora o ngā kanohi, ko te take matua me aro atu ki ngā karāhe whakapā ko te whakapai ake i te uruhanga hāora. Ko ngā karāhe whakapā hydrogel noa e whakawhirinaki ana ki te wai kei roto i te karāhe hei kawe i te hāora ki te kornea, engari he iti noa te kaha kawe o te wai, ā, he ngāwari te mimiti.Heoi, he rerekētanga nui te tāpiri o te silicon.Ngā monomer siliconehe hanganga koretake, he iti hoki ngā kaha i waenga i ngā ngota ngota, ā, he tino teitei te wairewatanga o te hāora i roto, e rima ngā wā ka nui ake te uruhanga hāora o ngā hauwairo silicone i tērā o ngā karaihe noa.
Kua ea te raruraru e pā ana ki te nui o te wai e uru ai te hāora,me ētahi atu painga kua puta.
Ki te nui haere te wai o ngā karaihe noa, i te roanga o te wā e mau ana, ka mimiti te wai, ka whakakīia anō mā roto i ngā roimata, ka maroke ai ngā kanohi e rua.
Heoi, he tika te nui o te wai o te silicone hydrogel, ā, ka noho pūmau tonu te wai ahakoa kua mau, nō reira kāore e ngāwari te maroke, ā, he ngohengohe, he whakamarie hoki ngā karu arotahi, e tuku ana i te kornea kia manawa noa.
Nā reira
He makuku tonu, he manawa hoki ngā karaihe whakapā i hangaia mai i te silicone hydrogel, ā, ka pai ake te whakamarie me te whakaiti i te kino o ngā kanohi, he painga kāore e taea te whakataurite ki ngā karaihe whakapā noa.Ahakoa ka taea anake te whakamahi i te silicone hydrogel hei hanga karaihe whakakore-poto, ā, kāore e taea te whakamahi ki ngā karaihe whakakore-ā-tau me ngā karaihe whakakore-haurua-ā-tau, koinei tonu te kōwhiringa pai rawa atu o ngā hua katoa.
