Nōnahea i hangaia ai ngā mōhiti kanohi?
Ahakoa he maha ngā puna kōrero e kī ana i hangaia ngā mōhiti kanohi i te tau 1317, ko te whakaaro mō ngā mōhiti kanohi i tīmata pea i te tau 1000 BC. E kī ana hoki ētahi puna kōrero nā Benjamin Franklin i hanga ngā mōhiti kanohi, ā, ahakoa nāna i hanga ngā karu kanohi rua, kāore e taea te kī ko tēnei kaihanga rongonui te kaihanga mō ngā mōhiti kanohi whānui.
I tēnei ao e hiahia ana te 60% o te taupori ki tētahi momo karaihe whakatikatika kia mārama ai te titiro, he uaua ki te whakaaro i tētahi wā kāore i te kitea ngā mōhiti tirohanga.
He aha ngā rauemi i whakamahia tuatahitia hei hanga mōhiti?
He rerekē te āhua o ngā tauira ariā o ngā mōhiti kanohi i ngā mōhiti rongoā e kitea ana e tātou i ēnei rā — he rerekē ngā tauira tuatahi i ia ahurea, i ia ahurea.
He rerekē ngā whakaaro o ngā kaihanga mō te whakapai ake i te tirohanga mā te whakamahi i ētahi rauemi. Hei tauira, i mōhio ngā Rōmana o mua ki te hanga karāhe, ā, i whakamahia aua rauemi hei hanga i ā rātou ake momo mōhiti.
Kāore i roa ka mōhio ngā kaihanga Itari ka taea te hanga karaihe kōhatu kia pūkohu, kia kōpiko rānei hei whakarato i ngā āwhina tirohanga rerekē ki te hunga he rerekē ngā hauātanga tirohanga.
I ēnei rā, he kirihou, he karāhe rānei te nuinga o ngā karaihe mō ngā mōhiti, ā, ka taea te hanga i ngā anga ki te konganuku, ki te kirihou, ki te rakau, tae noa ki te paura kawhe (kāo, kāore a Starbucks e hoko mōhiti - kāore anō kia pērā).
Te whanaketanga o ngā mōhiti kanohi
He otinga kotahi te rahi mō te katoa o ngā mōhiti tuatahi, engari kāore e pera i ēnei rā.
Nā te mea he rerekē ngā momo ngoikoretanga tirohanga o te tangata —te matapōkere(te tirohanga tata),te mātao rawa(tirohanga tawhiti),te astigmatism,āmiopia(kanohi mangere) me ētahi atu — mā ngā karāhe mōhiti rerekē ēnei hapa tirohanga ka whakatikahia.
Anei ētahi o ngā huarahi i whanake ai, i whakapai ake ai hoki ngā mōhiti i roto i te wā:
Ngā arotahi-rua:Ahakoa he āwhina ngā karāhe kōpiko ki te hunga he myopia mengā karāhe kōpikoHei whakatika i te hyperopia me te presbyopia, kāore he otinga kotahi hei āwhina i te hunga i pāngia e ngā momo ngoikoretanga tirohanga e rua tae noa ki te tau 1784. Ngā mihi, e Benjamin Franklin!
Ngā arotahi-toru:I te haurua rautau i muri i te hanganga o ngā arotahi-rua, ka puta mai ngā arotahi-toru. I te tau 1827, i hangaia e John Isaac Hawkins ngā arotahi hei āwhina i te hunga he nui te mate.te matapōkere, he āhuatanga tirohanga ka pā mai i muri i te 40 tau te pakeke. Ka pāngia te kaha o te tangata ki te kite tata (ngā tahua, ngā kāri tunu kai, ngā karere kuputuhi) e te presbyopia.
Ngā karāhe porowhita:I hangaia e Edwin H. Land ngā karaihe pōraro i te tau 1936. I whakamahia e ia he tātari polaroid i te wā i hangaia ai āna mōhiti kanohi. Ka tukuna e te pōraro ngā āheinga ārai-kanapa me te whakapai ake i te whakamarie mātakitaki. Mō te hunga e aroha ana ki te taiao, ka whakaratohia e ngā karaihe pōraro he huarahi hei pai ake te pārekareka ki ngā mahi whakangahau o waho, pērā ihī ikame ngā hākinakina wai, mā te whakanui ake i te tirohanga.
Ngā arotahi whakamua:Pērā i ngā karu arotahi-rua me ngā karu arotahi-toru,ngā arotahi whakamuahe maha ngā mana o ngā karu arotahi mō te hunga e uaua ana ki te kite mārama i ngā tawhiti rerekē. Heoi, ka whakaratohia e ngā karu arotahi he āhua ma, he āhua maeneene ake mā te piki haere o te mana puta noa i ia karu arotahi — haere rā, ngā rārangi!
Ngā karāhe whakaahua-koromiko: Ngā karaihe whakaahua-koromiko, e mōhiotia ana hoki ko ngā karāhe whakawhiti, ka pōuri i te rā, ā, ka noho mārama ki roto. I hangaia ngā karāhe photochromic i te tekau tau atu i 1960, engari i rongonui haere i te tīmatanga o te tekau tau atu i 2000.
Ngā karāhe ārai mārama kikorangi:Mai i te rongonuitanga o ngā rorohiko hei taputapu kāinga i ngā tau 1980 (me te kore e whakahua i ngā pouaka whakaata i mua atu me ngā waea atamai i muri mai), kua nui haere te taunekeneke mata matihiko. Mā te tiaki i ō kanohi mai i te mārama kikorangi kino e puta mai ana i ngā mata,mōhiti mārama kikorangika āwhina i te ārai i te taumahatanga o ngā kanohi matihiko me ngā whakararuraru i tō huringa moe.
