Kāore he mea hou ki te tini o te tangata ngā karāhe arotahi, ā, ko te karāhe arotahi te mea nui ki te whakatikatika i te myopia me te whakauru i ngā mōhiti. He momo paninga rerekē kei runga i ngā karāhe arotahi,pērā i ngā paninga kakariki, ngā paninga kikorangi, ngā paninga kikorangi-papura, tae atu ki ngā mea e kiia nei ko "ngā paninga koura manapori o te rohe" (he kupu kōrero mō ngā paninga koura).Ko te pakaru me te haehae o ngā paninga karaihe tētahi o ngā tino take mō te whakakapinga o ngā mōhiti. I tēnei rā, kia ako tātou mō ngā mōhiotanga e pā ana ki ngā paninga karaihe.
I mua i te hanganga o ngā karāhe karāhe, ko ngā karāhe karāhe anake ngā mea e wātea ana i te mākete. He pai ngā karāhe karāhe mō te taupū whakaata teitei, te tuku mārama teitei, me te pakeke teitei, engari he ngoikoretanga anō hoki: he ngāwari ki te pakaru, he taumaha, he kore haumaru, me ētahi atu.
Hei whakatika i ngā ngoikoretanga o ngā karaihe arotahi, kua rangahauhia, kua whakawhanakehia hoki e ngā kaihanga ngā rauemi maha hei whakakapi i te karaihe mō te hanga karaihe arotahi. Heoi, kāore i tino pai ēnei momo huarahi kē atu—he painga me he ngoikoretanga anō hoki tō ia rauemi, ā, kāore e taea te whakatutuki i tētahi mahi taurite e ea ai ngā hiahia katoa. Tae atu ki ngā karaihe arotahi kapia (ngā rauemi kapia) e whakamahia ana i ēnei rā.
Mō ngā karāhe kapia o ēnei rā, he mea nui te paninga.He maha anō ngā whakarōpūtanga o ngā rauemi kapia, pērā i te MR-7, MR-8, CR-39, PC, me te NK-55-C.He maha atu anō ngā rauemi kapia, he rerekē ngā āhuatanga o ia rauemi. Ahakoa he karāhe karāhe, he karāhe kapia rānei, ina pā te mārama mā te mata o te kapia, ka puta ētahi āhuatanga whatu: te whakaata, te hurihanga, te mimiti, te marara, me te tuku.
Paninga Ārai-Whakaata
I mua i te taenga o te mārama ki te mata o te arotahi, ko tōna kaha mārama he 100%. Heoi, ina puta atu i te taha o muri o te arotahi ka uru ki te kanohi tangata, kāore te kaha mārama i te 100%. Ko te teitei ake o te ōrau o te kaha mārama e puritia ana, ko te pai ake o te tuku mārama, ā, ko te teitei ake o te kounga me te taumira o te whakaahua.
Mō tētahi momo rauemi arotahi pūmau, ko te whakaiti i te ngaronga whakaata he tikanga noa hei whakapai ake i te tuku mārama. Ko te nui ake o te mārama e whakaatahia ana, ko te iti iho o te tuku mārama o te arotahi, ā, ko te ngoikore o te kounga whakaahua. Nō reira, kua noho te ārai-whakaata hei take matua me aro atu ki ngā arotahi kapia—ā, koinei te whakamahinga o ngā paninga ārai-whakaata (e mōhiotia ana ko ngā kiriata ārai-whakaata, ko ngā paninga AR rānei) ki ngā arotahi (i te tīmatanga, i whakamahia ngā paninga ārai-whakaata ki ētahi arotahi whatu).
Ka whakamahia e ngā paninga ārai-whakaata te kaupapa o te pokanoa. Ka ahu mai i a rātou te whanaungatanga i waenga i te kaha whakaata o te paparanga ārai-whakaata o te karu kua pania me ngā āhuatanga pēnei i te roangaru o te mārama taunga, te matotoru o te paninga, te taupū whakaata o te paninga, me te taupū whakaata o te papa karu. Mā tēnei hoahoa ka whakakorea ngā hihi mārama e haere ana i roto i te paninga, ka whakaitihia te ngaronga o te kaha mārama i runga i te mata o te karu, ā, ka whakapai ake i te kounga me te taumira o te whakaahua.
Ko te nuinga o ngā paninga ārai-whakaata he mea hanga mai i ngā waikura konganuku parakore teitei pērā i te waikura titanium me te waikura cobalt. Ka pania ēnei rauemi ki te mata o te arotahi mā te tukanga mimiti (paninga mimiti korehau) kia puta ai he pānga ārai-whakaata whai hua. He maha ngā toenga e toe ana i muri i te tukanga paninga ārai-whakaata, ā, ko te nuinga o ēnei paninga he tae kakariki.
Ko te tikanga, ka taea te whakahaere i te tae o ngā paninga ārai-whakaata—hei tauira, ka taea te hanga hei paninga kikorangi, paninga kikorangi-papura, paninga papura, paninga hina, me ētahi atu. He rerekē ngā tukanga whakaputa o ngā paninga o ngā tae rerekē. Hei tauira, ko ngā paninga kikorangi: me whakahaere he whakaata iti iho mō ngā paninga kikorangi, ā, ka uaua ake te tukanga paninga i ērā o ngā paninga matomato. Heoi, ko te rerekētanga o te whakawhiti mārama i waenga i ngā paninga kikorangi me ngā paninga matomato he iti iho i te 1%.
I roto i ngā hua arotahi, ko ngā paninga kikorangi te nuinga o te wā e whakamahia ana mō ngā arotahi waenga-ki-te-pai. Ko te tikanga, he nui ake te kaha o te mārama o ngā paninga kikorangi i ngā paninga kakariki (me mōhio ko tēnei "i roto i te tikanga"). Nā te mea he ranunga ngaru te mārama me ngā roangaru rerekē, ā, he rerekē ngā tūranga whakaahua o ngā roangaru rerekē i runga i te retina. I raro i ngā āhuatanga noa, ka whakaahuahia te mārama kōwhai-kakariki ki runga i te retina, ā, he nui ake te takoha a te mārama kakariki ki ngā mōhiohio tirohanga—nō reira, he tairongo ake te kanohi tangata ki te mārama kakariki.
