I kēia manawa, aia ʻelua ʻano mea aniani ma ka mākeke, ʻo kekahi he mea aniani, ʻo kekahi he mea resin. Ua māhele ʻia nā mea resin i CR-39 a me polycarbonate (mea PC).

ʻO nā aniani bifocal a i ʻole nā aniani bifocal he mau aniani ia e loaʻa ana ʻelua mau wahi hoʻoponopono i ka manawa like a hoʻohana nui ʻia e hoʻoponopono i ka presbyopia. ʻO ka wahi mamao i hoʻoponopono ʻia e ka aniani bifocal ua kapa ʻia ʻo ka wahi mamao, a ʻo ka wahi kokoke ua kapa ʻia ʻo ka wahi kokoke a me ka wahi heluhelu. ʻO ka maʻamau, he nui ka ʻāpana distal, no laila ua kapa ʻia hoʻi ʻo ia ke kiʻiʻoniʻoni nui, a he liʻiliʻi ka ʻāpana proximal, no laila ua kapa ʻia ʻo ia ʻo ke kiʻiʻoniʻoni liʻiliʻi.
