Pono e noʻonoʻo pono ʻia kahi mau lens kūpono iā ʻoe iho i hui pū ʻia me kā mākou degere, ka mamao o ka haumāna, ke ʻano o ke kiʻi, ka waihona kālā, ka hoʻohana ʻana i ke ʻano a me nā mea ʻē aʻe.
ʻO ka helu hoʻohālikelike e like me ka nui o ka kāmaʻa.ʻO ka manaʻo o ka brand, ʻo ia nā ʻāpana maʻamau, hiki ke hoʻomaopopo nui ʻia e like me ka mānoanoa o ka lens.ʻO ke kiʻekiʻe o ka helu refractive, ʻoi aku ka lahilahi o ka lens.ʻO ka myopia 500 degere like, ʻo ka lens 1.61 he 1.56 lahilahi.
ʻOiai ʻoi aku ka kiʻekiʻe o ka helu refractive, ʻoi aku ka lahilahi.ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka refractive index, ʻo ia ka haʻahaʻa o ka helu Abbe.E koho i ke kēkelē kūpono iā ʻoe iho
Loaʻa nā helu Abbe like ʻole i nā ʻōlelo kuhikuhi refractive like ʻole.ʻO kēia nā helu Abbe e pili ana i nā index refractive like ʻole:
1.50
Helu helu 58
ʻO ka helu Abbe kiʻekiʻe loa kahi kokoke i ka ʻike ʻike o ka maka ʻōlohelohe.E mānoanoa loa ka lens spherical inā kiʻekiʻe ke degere.He kūpono wale ia no ka myopia haʻahaʻa i loko o 250 degere.He nui ke kuʻekuʻe kumu, a ʻaʻole kūpono ia no nā aniani kiʻi nui.
1.56
Helu Abbe 35-41
He haʻahaʻa ka helu Abbe, ʻo 1.56 ka papa kuhikuhi refractive haʻahaʻa loa o ka hapa nui o nā lens lens, ʻoi aku ka maikaʻi a kūpono i ka myopia i loko o 300 degere;ʻAʻole ʻōlelo ʻia inā ʻoi aku ka mahana ma mua o 350 degere.E ʻoi aku ka mānoanoa o ka lens ke kiʻekiʻe ke degere.
1.60
Helu Abbe 33-40
ʻO 1.60 a me 1.61 nā ʻano maʻamau kākau ʻokoʻa me ka index refractive like.ʻAʻohe ʻokoʻa.Wahi a nā mana like ʻole a me nā moʻo, ʻokoʻa ka helu o Abbe mai 33-40.No ka laʻana, ʻo ka pale radiation o ka mahina ʻālohilohi 1.60 he 33 dB, a ʻo ka moʻo PMC o ka mahina mālamalama he 40 dB.
1.67
Helu 32
Helu Abbe haʻahaʻa, hoʻopuehu nui a me ka hopena kiʻi maʻamau.Ma ka laulā o 550-800 degere myopia, 1.61 ka mānoanoa loa, ka palena kālā, a ʻaʻole i oi aku ma mua o 1.71, no laila, ʻo 1.67 kahi koho kuʻikahi.
1.71
Helu 37
ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka huaʻōlelo refractive o ka lens, ʻoi aku ka haʻahaʻa o ka helu Abbe a ʻoi aku ka nui o ka hoʻopuehu ʻana.Eia nō naʻe, me ka holomua o ka ʻenehana mea lens, ua haki ʻia kēia lula.No ka laʻana, ʻoi aku ka lahilahi o 1.71 ma mua o 1.67, a ʻoi aku ka kiʻekiʻe o ka helu Abbe.
1.74
Helu 33
He haʻahaʻa ka helu refractive a me ka helu Abbe o ka lens resin, a he kiʻekiʻe ke kumukūʻai.Eia naʻe, no ka myopia kiʻekiʻe, ʻaʻohe koho ʻē aʻe.Ma hope o nā mea a pau, ʻo ka mānoanoa ka ʻike intuitive loa.Hiki ke noʻonoʻo ʻia ma luna o 800 degere, a ʻoi aku ma mua o 1000 degere hiki ke noʻonoʻo ʻia me ka noʻonoʻo ʻole i kekahi mea ʻē aʻe.Hoʻohālikelike wale i ka 1.74.
