Ma ke kekelē like, ʻo ke kiʻekiʻe o ka refractive index, ʻo ka lahilahi o ka lens. ʻO ka refractive index o 1.50 a i ʻole 1.56 e kūpono no ke koho ʻana i loko o 300 degere, ʻo ka refractive index o 1.56 a i ʻole 1.60 e kūpono no ke koho ʻana ma waena o 300 a me 500 degere, ʻo ka refractive index o 1.67 e kūpono no ke koho ʻana ma waena o 500 a me 800 degere, a ʻo ka refractive index o 1.70 a me 1.74 e kūpono no ke koho ʻana ma luna o 800 degere.

E like me kā kākou e ʻike nei, ʻo ka pōmaikaʻi nui o ka 1.50 refractive index ʻo ia ka loaʻa ʻana o kahi helu Abbe kiʻekiʻe o 58, ukali ʻia e ke kumukūʻai kūpono, kahi kūpono loa no ka poʻe me ka myopia haʻahaʻa.

Koho ke keiki i ka lens me ka refractive index o 1.50. Inā he pilikia ʻike maka kāu keiki, ʻaʻole kūpono ke komo i nā lens pale a me ka kaohi, a ʻaʻole ʻae ka waihona kālā i ka hoʻohana ʻana i nā lens pale a me ka kaohi. A laila ʻo nā lens maʻamau ka mea kūpono loa no nā keiki (myopia ma lalo o 400 degere). He lens index 1.50 ia.

1. Helu Abbe kiʻekiʻe: hoʻemi i ka hopena o ka hoʻopuehu ʻana ma ke akāka. ʻOi loa aku i nā keiki ʻike mamao, kahi i nui ai ka mānoanoa o ke kikowaena, he mea nui loa ka helu Abbe. (He helu Abbe ko ka maka kanaka he 58.6, ʻoiai he 58 ka helu Abbe o ka lens refractive index 1.50)

2. Makepono: Hoʻololi koke nā keiki i nā aniani maka, a he mea nui e makepono lākou.

3. Ua ʻae ʻia hoʻi ka paʻakikī: i ka hoʻohālikelike ʻia me 1.56, ʻoi aku ke kiʻekiʻe o ka paʻakikī a me ka mānoanoa, e hōʻemi ana i ka hopena o nā ʻōpala ma ka moakāka.

ʻO ka hopena: e hoʻonui i ka nui o nā aniani a kāu keiki e ʻaʻahu ai e like me ka maka kanaka.
