E koho i kāu

"ʻOi aku ka maikaʻi ʻole o ka permeability oxygen o nā lens contact ke hoʻohālikelike ʻia me nā lens contact maʻamau, a inā nui loa ke anawaena o ka lens contact, e hoʻopilikia ia i ka neʻe ʻana o ka lens, e hoʻonui ai i ka hopena o ka permeability oxygen."

ʻŌlelo Maʻamau

Ma ke ʻano laulā, inā makemake ʻoe i kahi hopena kūlohelohe, hiki iā ʻoe ke koho i ka 13.8mm no nā maka liʻiliʻi, a me 14.0mm no ka poʻe me nā maka nui iki. E ʻike iki ʻia ka 14.2mm i ke kanaka maʻamau, no laila hiki iā ʻoe ke koho i ka 13.8mm-14.0mm no ka hana o kēlā me kēia lā, ke kula, a me ka launa pū ʻana.
