1.523 Aniani Bifocal Photochromic Photogrey Optical Lens

Ke hoʻonāwaliwali ʻia ka hoʻoponopono ʻana o ka maka ma muli o ka makahiki, pono ʻo ia e hoʻoponopono kaʻawale i kāna ʻike no ka ʻike mamao a kokoke. I kēia manawa, pono pinepine ʻo ia e ʻaʻahu i ʻelua mau makaaniani ma kahi kaʻawale, he mea kūpono ʻole. No laila, pono e wili i ʻelua mana refractive like ʻole ma ka lens hoʻokahi e lilo i mau lens ma nā wahi ʻelua. Kapa ʻia ia mau lens he lens bifocal a i ʻole nā ​​aniani bifocal.

ʻAno hui:ʻo ia ka hoʻohui ʻana i ka mea lens me ka helu hoʻopaʻapaʻa kiʻekiʻe i loko o ka ʻāpana concave ma ka pā nui i ka wela kiʻekiʻe, a ʻoi aku ka haʻahaʻa o ka papa kuhikuhi refractive o ka pā nui. A laila e holo i ka ʻili o ka ʻāpana ʻāpana e hana i ka curvature o ka ʻāpana ʻāpana e kūlike me ka ʻāpana nui. ʻAʻohe manaʻo o ka palena. ʻO ka heluhelu ʻana i ka A e pili ana i ka mana refractive F1 o ka ʻili mua o ke kahua mamao o ka hihiʻo, ka curvature FC o ke arc concave kumu a me ka ratio hui. ʻO ka lākiō hui ʻana he pilina hana ma waena o ka helu kuhikuhipuʻuone o nā mea lens hui pū ʻelua, kahi n e hōʻike ana i ka kuhikuhi kuhikuhi refractive o ke aniani nui (maʻamau ka aniani lei aliʻi) a ʻo ka ns e hōʻike ana i ka kuhikuhina refractive o ka sub-pepa (ke aniani flint) me he waiwai nui, a laila ka ratio hui 'ana k=(n-1)/(nn), pela A=(F1-FC)/k. Hiki ke ʻike ʻia mai ka ʻōlelo ma luna nei ma ke kumumanaʻo, e hoʻololi ana i ka curvature o mua o ka pā nui, ka concave arc curvature a me ka sub-plate refractive index hiki ke hoʻololi i ka degere kokoke, akā ʻoiaʻiʻo, hiki ke hoʻokō ʻia ma ka hoʻololi ʻana. ka papa kuhikuhi hoʻopaʻapaʻa sub-plate. Hōʻike ka papa 8-2 i ka ʻōlelo kuhikuhi refractive o ke aniani flint sub-sheet i hoʻohana mau ʻia ma ka honua no ka hana ʻana i nā aniani aniani bifocal hoʻohui like ʻole.
