ʻOi aku ke kiʻekiʻe o ka helu kuhi refractive o ka lens, ʻoi aku ka lahilahi o nā aniani, ʻoi aku ka nui o ka density, ka paʻakikī a me ka maikaʻi. Ma ke ʻano ʻē, ʻoi aku ka haʻahaʻa o ka helu kuhi refractive, ʻoi aku ka mānoanoa o ka lens, ʻoi aku ka liʻiliʻi o ka density, ʻoi aku ka maikaʻi ʻole o ka paʻakikī, ʻoi aku ka paʻakikī o ke aniani ma ke ʻano laulā, no laila ʻo ka helu kuhi refractive ma kahi o 1.7, a ʻoi aku ka maikaʻi ʻole o ka paʻakikī o ka ʻili resin, haʻahaʻa iki ka helu kuhi refractive. ʻO ka ʻāpana resin ma ka mākeke i kēia manawa ka helu kuhi refractive maʻamau o 1.499 a pēlā paha. ʻOi aku ka maikaʻi o ka mana ultra-thin, nona ka helu kuhi refractive ma kahi o 1.56 a hoʻohana nui ʻia.
