Ke ulu nui nei ka myopia i nā poʻe ʻōpio, ua hoʻonui ʻia ka nui o nā koho lens no nā keiki, i mea e hopohopo ai nā mākua he nui. No ka mea, ʻoi aku ka paʻakikī o nā koi eyewear o nā keiki ma mua o nā mākuaNā leka uilaʻoi aku ka maikaʻi no ka hoʻomohala ʻana i nā keiki a me nā ʻōpio?

ʻO nā lens holomua kahi ʻano o nā aniani aniani e hāʻawi i ka holomua ʻoluʻolu a paʻa ʻole o nā mana hoʻoponopono ʻike i loko o kahi lens hoʻokahi. Ua ʻike ʻia lākou he bifocals laina ʻole a i ʻole nā ​​lens varifocal.

I kēia mau makahiki i hala iho nei, ua kaulana nā aniani lens uliuli no ko lākou mau pono kūpono i ke olakino o ka maka a me ka maikaʻi holoʻokoʻa.

He aha ke kukui uliuli? ʻO 380-780NM ka nalu o ke kukui ʻike ʻia, a ʻo ke kukui uliuli ʻo 380-50NM, ʻo ia kekahi o ka nalu pōkole loa a me ka ikehu kiʻekiʻe.

He kūpono no ka hoʻoponopono ʻana i ka emi ʻana, i ka manawa like e ʻike i kahi mamao, nani a i ka manawa like paha e ʻike i kahi kokoke i nā pono like ʻole o ka poʻe (ʻoi aku ka ʻike ʻana i nā pono o ke kamepiula a me ke kelepona paʻalima), ʻaʻole pono ʻoe e koho pinepine a komo i nā aniani.

Nīnau pinepine ka poʻe inā pono lākou e ʻaʻahu i nā aniani pale polū e pale aku i ko lākou mau maka ke nānā aku i kā lākou kamepiula, pad a i ʻole kelepona paʻa. Ua pololei anei ka myopia laser ma hope o ke kaʻina hana pono e ʻaʻahu i nā aniani anti-blue ray e pale ai i ka maka?

ʻO nā lens holomua, e pili ana i nā lens multi-focal, ua hoʻohana nui ʻia ma ʻEulopa a me ʻAmelika Hui Pū ʻIa, akā ua kaulana wale ʻia ma Kina i nā makahiki he 10 i hala. E nānā kākou i ke kiʻi o nā makaaniani multifocal holomua.

ʻO ka helu kaulana o nā kiʻiʻoniʻoni holomua ma nā wahi i kūkulu ʻia e like me ʻEulopa a me ʻAmelika Hui Pū ʻIa ua ʻoi aku ma mua o 70%, a ʻo nā kiʻiʻoniʻoni holomua he 30% o ka nui o ke kūʻai aku, me nā kūʻai makahiki he 500 miliona.

ʻO nā mea nui ʻekolu o nā lens optical: he aha nā ʻokoʻa kikoʻī a me nā pono a me nā hemahema o nā lens optical kaulana ʻekolu.

ʻO ka lens maʻamau hale kaʻa i kapa ʻia he ʻāpana hale kaʻa, hana hoʻonohonoho. ʻO ka lens i hoʻonohonoho ponoʻia e ka hale kaʻa e pili ana i ka huahana hikiʻole ke hoʻokōʻia e ka hoʻolakoʻana i nā'āpana i kēia manawa a hoʻohanaʻia e hālāwai me nā pono kūikawā.
