I te roa haere o ngā hāora awatea, me te kaha haere o te rā, e hikoi ana i ngā tiriti, ehara i te mea uaua ki te kite he nui ake te hunga e mau ana i ngā karāhe whakaahua-ira i mua. Ko ngā mōhiti kanohi kua tohua he puna moni whiwhi e piki haere ana i roto i te umanga hokohoko mōhiti kanohi i ngā tau tata nei, ā, ko ngā karāhe whakaahua-ira tonu te mea nui o ngā hoko raumati. Ko te manako o te mākete me te kaihoko ki ngā karāhe whakaahua-ira i ahu mai i tōna momo, te tiakitanga mārama, me ngā hiahia e pā ana ki te taraiwa.
I ēnei rā, kua nui ake te mōhio o te tangata ki te kino o ngā hihi ultraviolet ki te kiri. Ko te ārai rā, ngā parasol, ngā pōtae baseball, tae atu ki ngā taupoki ringa hiraka hukapapa kua noho hei taonga nui mō ngā haerenga raumati. Ko te kino o ngā hihi UV ki ngā kanohi, kāore pea e kitea wawetia pērā i te kiri parauri, engari i roto i te wā roa, ka taea e te nui o te pānga te arahi ki ngā hua kino ake. Kua whakamātauhia he hononga tika, he hononga ā-kore rānei o ngā mate kanohi pērā i te katarata me te pirau kanohi e pā ana ki te koroheketanga ki te pānga UV. I tēnei wā, kāore he ariā kotahi a ngā kaihoko Haina mō te "āhea me mau mōhiti kanohi" i runga i ngā āhuatanga o te rā. He maha ngā wā, me tiaki te taiao rama o waho i te mārama, engari e whakaaro ana te nuinga o ngā kaihoko he "koretake" ā, kāore e pai ki te mau. I runga i tēnei horopaki, ko ngā karaihe photochromic, e whakarato ana i te whakatikatika tirohanga me te tiaki mārama me te kore e hiahiatia te tango pērā i ngā mōhiti kanohi noa i roto i ngā tautuhinga rerekē, kei te manakohia e te tini o te tangata.
Ko te kaupapa o te huringa tae i roto i ngā karāhe whakaahua-iraira e ahu mai ana i te "whakaahua-ira ...
Ko te huringa tae o ngā karāhe whakaata-irahiko te hua o tētahi raupapa o ngā tauhohenga matū ka taea te whakahuri, me te mārama (tae atu ki te mārama e kitea ana me te mārama ultraviolet) e whai wāhi nui ana ki ēnei tauhohenga. He mea noa, ko te whai huatanga o te tukanga huringa tae ka pāngia e ngā wā me ngā āhuatanga o te rangi, nō reira kāore e mau tonu te pānga pumau me te pumau.
I te nuinga o te wā, i te rangi paki, ka kaha ake te kaha o ngā hihi ultraviolet, ka nui ake te kaha o te tauhohenga photochromic, ā, ka pōuri rawa ngā karāhe. He rerekē, i ngā rā kapua, ina ngoikore ake ngā hihi UV me te kaha o te mārama, ka mārama ake te āhua o ngā karāhe. Hei tāpiri, i te pikinga o te pāmahana, ka mārama haere te tae o ngā karāhe photochromic. I te rerekētanga, i te hekenga o te pāmahana, ka pōuri haere ngā karāhe. Nā te mea i ngā pāmahana teitei ake, ka whakahokia ngā katote hiriwa me ngā katote halide, i pirau i mua, ki te halide hiriwa i raro i te kaha nui, ka whakamārama i te tae o ngā karāhe.
Mō ngā karaihe whakaahua-ira, kei reira anō ētahi pātai me ngā mōhiotanga e pā ana ki ēnei:
He iti ake te mārama/te tuku mārama o ngā karāhe arotahi whakaahua-ira i ērā o ngā karāhe arotahi noa?
Kāore he tae o ngā karāhe arotahi whakaahua-kounga teitei ina kore e whakahohea, ā, kāore e iti ake te tuku mārama i ērā o ngā karāhe arotahi noa.
He aha ngā karāhe arotahi whakaahua-ira kāore e huri te tae?
E rua ngā āhuatanga e pā ana ki te korenga o te huringa tae o ngā karāhe whakaahua-ira: ngā āhuatanga mārama me te kaihoko whakaahua-ira (te hiriwa halide). Ki te kore e rerekē te tae ahakoa i roto i te mārama kaha me te hihi UV, tera pea kua pakaru te kaihoko whakaahua-ira.
Ka kino haere rānei te pānga huri-tae o ngā karu arotahi whakaahua-ira i roto i te wā?
Pērā i ngā karaihe noa, he roa te ora o ngā karaihe whakaahua-ira. Mēnā ka tiakina tika, ka roa ake i te 2-3 tau.
He aha i pōuri haere ai ngā karāhe arotahi whakaahua-ira i roto i te wā?
Ki te pōuri haere ngā karāhe whakaahua-ira i roto i te wā, ā, kāore e taea te hoki anō ki te mārama, nā te mea kāore e taea e te karāhe whakaahua-ira te hoki anō ki tōna āhua taketake i muri i te hurihanga o te tae, ka puta he tae toenga. He nui ake te kitea o tēnei āhuatanga i roto i ngā karāhe kounga-iti, engari kāore e pāngia ngā karāhe whakaahua-ira kounga-pai e tēnei raruraru.
He aha i tino kitea ai ngā karāhe hina i te mākete?
Ka taea e ngā karāhe hina te mimiti i te hihi whero me te 98% o ngā hihi UV. Ko te painga nui o ngā karāhe hina ko te kore e whakarerekē i ngā tae taketake o ngā mea, ka whakaiti i te kaha o te mārama. Ka mimiti ōritetia te mārama puta noa i ngā whānuitanga katoa, nō reira ka pōuri ake te āhua o ngā mea engari kāore he rerekētanga nui o te tae, ka puta he tirohanga pono, ā-taiao. Hei tāpiri, he tae kūpapa te hina, he pai mō te katoa, ā, ka nui ake te rongonui i te mākete.
