I ka manawa hea i hana ʻia ai nā maka aniani?
ʻOiai he nui nā kumu i ʻōlelo ʻia ua hana ʻia nā makaaniani i ka makahiki 1317, ua hoʻomaka paha ka manaʻo no nā aniani i ka makahiki 1000 BC Ua ʻōlelo pū kekahi mau kumu ua hana ʻo Benjamin Franklin i nā makaaniani, a ʻoiai ʻo ia i haku i nā makaaniani bifocals, ʻaʻole hiki ke ʻike ʻia kēia mea hana kaulana i ka hana ʻana i nā aniani. laulaha.
Ma kahi honua kahi 60% o ka heluna kanaka e pono ai i kekahi ʻano o nā lens hoʻoponopono e ʻike maopopo, paʻakikī ke kiʻi i kahi manawa ʻaʻole i puni nā maka aniani.
He aha nā mea i hoʻohana mua ʻia no ka hana ʻana i nā aniani?
ʻOkoʻa iki nā hiʻohiʻona noʻonoʻo o nā makaaniani ma mua o nā aniani kuhikuhi a mākou e ʻike nei i kēia mau lā - ʻoiai nā hiʻohiʻona mua i ʻokoʻa mai ka moʻomeheu i ka moʻomeheu.
Ua loaʻa i nā mea hana like ʻole ko lākou manaʻo ponoʻī no ka hoʻomaikaʻi ʻana i ka ʻike me ka hoʻohana ʻana i kekahi mau mea.No ka laʻana, ʻike ka poʻe Roma kahiko i ka hana aniani a hoʻohana i kēlā mea e hana i kā lākou ʻano o nā maka aniani.
Ua aʻo koke ka poʻe mea haku ʻItalia e hiki ke hana ʻia ke aniani pōhaku i convex a i ʻole concave e hāʻawi i nā kōkua ʻike like ʻole i ka poʻe me nā hemahema ʻike like ʻole.
I kēia mau lā, he ʻilika a i ʻole aniani paha nā aniani aniani a hiki ke hana ʻia nā papa me ka metala, ka plastic, ka lāʻau a me ka pā kofe (ʻaʻole, ʻaʻole kūʻai aku ʻo Starbucks i nā aniani - ʻaʻole naʻe).
ʻO ka ulu ʻana o nā maka aniani
ʻO nā maka aniani mua i ʻoi aku ka nui o ka hopena hoʻokahi, akā ʻaʻole maoli kēlā i kēia lā.
No ka mea, loaʻa i nā kānaka nā ʻano hemahema ʻike like ʻole -myopia(ʻike kokoke),hyperopia(ʻike maka),astigmatism,amblyopia(maka palaualelo) a me nā mea hou aʻe - hoʻoponopono nā aniani aniani ʻokoʻa i kēia mau hewa refractive.
Eia kekahi mau ʻano o ka ulu a hoʻomaikaʻi ʻana o nā aniani i ka wā.
Bifocals:ʻOiai kōkua nā lens convex i ka poʻe me ka myopia anā lens concavehoʻoponopono i ka hyperopia a me ka presbyopia, ʻaʻohe ala hoʻokahi e kōkua ai i ka poʻe i loaʻa i nā ʻano pilikia ʻelua a hiki i ka makahiki 1784. Mahalo, Benjamin Franklin!
Trifocals:ʻO ka hapalua haneli ma hope o ka hana ʻana o nā bifocals, ua ʻike ʻia nā trifocals.I ka makahiki 1827, ua hana ʻo John Isaac Hawkins i nā leki e mālama i ka poʻe me ka maʻi koʻikoʻipresbyopia, he maʻi hihiʻo i loaʻa maʻamau ma hope o ka makahiki 40. Pili ka Presbyopia i ka hiki ke ʻike i kahi kokoke (menu, kāleka ʻai, nā leka uila).
Nā lens polarized:Ua hana ʻo Edwin H. Land i nā lens polarized i ka makahiki 1936. Ua hoʻohana ʻo ia i kānana polaroid i ka hana ʻana i kāna mau aniani.Hāʻawi ʻo Polarization i nā mana anti-glare a hoʻomaikaʻi i ka ʻoluʻolu nānā.No ka poʻe makemake i ke ʻano, hāʻawi nā lens polarized i kahi ala e hauʻoli maikaʻi ai i nā leʻaleʻa waho, e like melawaiʻaa me nā haʻuki wai, ma ka hoʻonui ʻana i ka ʻike.
Nā lens holomua:E like me nā bifocals a me nā trifocals,nā lens holomualoaʻa i nā mana lens he nui no ka poʻe pilikia ke ʻike maopopo ma nā mamao like ʻole.Eia naʻe, hāʻawi nā mea holomua i kahi nānā maʻemaʻe, ʻoi aku ka maʻemaʻe ma o ka holomua ʻana i ka mana ma kēlā me kēia lens - aloha, nā laina!
Nā lens Photochromic: Nā leka Photochromic, i ʻōlelo ʻia hoʻi he mau lens transitions, ʻeleʻele i ka lā a noho mālie i loko o ka hale.Ua hana ʻia nā lens Photochromic i nā makahiki 1960, akā ua kaulana lākou i nā makahiki 2000.
Nā lens pale kukui polū:Ma muli o ka lilo ʻana o nā lolouila i nā mea hana hale kaulana i ka makahiki 1980 (ʻaʻole e haʻi ʻia i nā TV ma mua o kēlā a me nā kelepona ma hope), ua ʻoi aku ka nui o ka launa ʻana o ka pale kikohoʻe.Ma ka pale ʻana i kou mau maka mai ke kukui uliuli ʻino e puka mai ana mai nā pale,aniani kukui uliulihiki ke kōkua i ka pale ʻana i ka maka kikohoʻe a me nā pilikia i kāu pōʻai hiamoe.
Inā makemake ʻoe e ʻike i nā ʻano lens hou aku, e ʻoluʻolu e nānā i kā mākou ʻaoʻao ma aneʻihttps://www.universeoptical.com/stock-lens/.
