Hōʻike Hōʻike Kiʻekiʻe Uila Uila 1.74
He aha nā Lenses kiʻekiʻe 1.74?
Inā loaʻa iā ʻoe kahi palapala kauoha ikaika loa, pono ʻoe e noʻonoʻo i ka Ultra Thin High Index 1.74 Lenses.
ʻO nā lens Index 1.74 ka ʻoi aku ka lahilahi, palahalaha, a ʻoi aku ka maikaʻi o nā lens i kūkulu ʻia.
He 40% ka ʻoi aku o ka ʻoi aku o ka lahilahi ma mua o ka plastic a me ka 10% ka lahilahi ma mua o 1.67 mau lens index kiʻekiʻe, e hāʻawi ana iā ʻoe i ka ʻenehana a me nā mea hoʻonaninani. ʻOi aku ka maikaʻi o ka lens thinner, e hōʻemi ana i ka distortion i hana ʻia me nā lens haʻahaʻa haʻahaʻa.
He aha ka mānoanoa lens e koho ai?
Inā haʻahaʻa ʻoe, a pōkole paha ka ʻike, e pōmaikaʻi ʻoe i nā lens ʻoi aku ka ʻoi aku ka ʻike ʻia o ka mānoanoa lihi o kāu mau lens.
ʻO nā lens me ka helu kuhikuhi refractive o 1.6 he mea kūpono ia no nā ʻōlelo kuhikuhi ma kahi o ka waiwai o kāu palapala SPH ma waena o -2.50 a me -4.00.
Ma waena o -4.00 a me -6.00 makemake mākou i kahi lens me ka index refractive o 1.67, a ʻoi aku ka maikaʻi o nā ʻōlelo kuhikuhi ma luna o kēlā lens me ka index refractive o 1.74.
Inā ʻoi aku ka nui o kāu kau ʻana -5.00, pono mākou i kahi ana pololei o ka mamao ma waena o kāu mau haumāna, i kapa pinepine ʻia ʻo PD.
No ka mea ʻokoʻa nā lens no ka ʻike lōʻihi a me ka pōkole, aia nā manaʻo like ʻole no kēlā me kēia.
He kūpono nā lens hi-index 1.74 no
1. He kūpono no nā kuhikuhi mana kiʻekiʻe ma nā pae +10.00 a -10.00
2. ʻAʻole ʻōlelo ʻia no nā aniani semi-rimless a i ʻole rimless
3. ʻOi aku ka lōʻihi o ka ʻōpala
4. Mākaʻikaʻi Optical
5. 50% ho'ēmi mānoanoa
6. 30% ho'ēmi kaumaha
7. He kūpono no nā papa nui
