Ma ka pae like, ʻoi aku ka kiʻekiʻe o ka refractive index, ʻoi aku ka lahilahi o ka lens.ʻO ka index refractive o 1.50 a i ʻole 1.56 kūpono no ke koho ʻana i loko o 300 degere, ʻo ka refractive index o 1.56 a i ʻole 1.60 kūpono no ke koho ʻana ma waena o 300 a me 500 degere, ʻo ka refractive index o 1.67 kūpono no ke koho ʻana ma waena o 500 a me 800 degere, a me ka refractive. ʻO index o 1.70 a me 1.74 kūpono no ke koho ʻana ma luna o 800 degere.
E like me kā mākou i ʻike ai, ʻo ka pōmaikaʻi nui loa o ka 1.50 refractive index ʻo ia ka helu Abbe kiʻekiʻe o 58, a ukali ʻia e ke kumukūʻai kūpono, i kūpono loa i nā poʻe me ka myopia haʻahaʻa.

Koho ke keiki i ka lens me ka index refractive o 1.50.Inā loaʻa i kāu keiki nā pilikia ʻike, ʻaʻole kūpono ke komo ʻana i nā lens pale a me ka hoʻokele, a ʻaʻole ʻae ka waihona kālā i ka hoʻohana ʻana i nā lens pale a hoʻokele.A laila ʻoi aku ka maikaʻi o nā lens maʻamau no nā keiki (myopia ma lalo o 400 degere).He lens index 1.50.
1. He helu Abbe kiʻekiʻe: hoʻemi i ka hopena o ka hoʻopuehu ʻana i ka mālamalama.ʻOi aku i nā keiki ʻike maka, kahi nui ka mānoanoa waena, ʻoi aku ka nui o ka helu Abbe.(He helu Abbe ko ka maka kanaka he 58.6, aʻo ka 1.50 refractive index lens he Abbe helu o 58)
2. Māmā: Ho'ololi koke nā keiki i nā lens, a he mea nui ke kū'ai.
3. ʻAe ʻia ka paʻakikī: ke hoʻohālikelike ʻia me 1.56, ʻoi aku ka kiʻekiʻe o ka paʻakikī a me ka paʻakikī, e hōʻemi ana i ka hopena o nā ʻōpala i ka mālamalama.
ʻO ka laina lalo: e hoʻonui i ka nui o nā makaaniani a kāu keiki e ʻaʻahu ai e like me ka maka o ke kanaka.
