Me ka nānā ʻole i ke kumu e pono ai ʻoe i kahi lāʻau lapaʻau no ka hoʻoponopono ʻana i ka ʻike kokoke, hana like nā bifocals a pau. Aia kahi ʻāpana liʻiliʻi ma ka ʻaoʻao haʻahaʻa o ka lens i ka mana e pono ai e hoʻoponopono i kāu ʻike kokoke. ʻO ke koena o ka lens no kāu ʻike mamao. ʻO ka ʻāpana lens i hoʻolaʻa ʻia no ka hoʻoponopono ʻana i ka ʻike kokoke hiki ke lilo i hoʻokahi o nā ʻano like ʻole.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
