Kodayake yawan ruwan tabarau na hydrogel sun fi girma, koyaushe sun kasance marasa gamsuwa dangane da iskar oxygen.Daga hydrogel zuwa silicone hydrogel, ana iya cewa an sami tsalle mai inganci.Don haka, a matsayin mafi kyawun ido a halin yanzu, menene yake da kyau game da silicone hydrogel?
Silicone hydrogel ne mai matukar hydrophilic Organic polymer abu tare da high oxygen permeability.Daga yanayin lafiyar ido, mahimmin batun da ruwan tabarau ke buƙatar magance shi shine inganta haɓakar iskar oxygen.Ruwan tabarau na ruwan tabarau na hydrogel na yau da kullun sun dogara da ruwan da ke cikin ruwan tabarau a matsayin mai ɗaukar iskar oxygen zuwa cornea, amma ƙarfin jigilar ruwa yana da iyaka kuma yana ƙafe cikin sauƙi.Duk da haka, ƙari na silicon yana haifar da babban bambanci.Silicone monomerssuna da tsarin sako-sako da ƙananan ƙwayoyin intermolecular, kuma solubility na iskar oxygen a cikin su yana da girma sosai, wanda ya sa iskar oxygen na silicone hydrogels ya fi sau biyar fiye da na ruwan tabarau na yau da kullum.
Matsalolin da iskar oxygen dole ne ya dogara da abun ciki na ruwa an warware shi,kuma an kawo wasu fa'idodi.
