I ngā tau tata nei, kua tere te whanaketanga o te umanga taiaho o Haina, kua whānui haere te mākete tono, ā, kua pakaruhia he maha ngā raruraru, kua wetekina he maha ngā hangarau matua, ā, kua āta whakakorea te āhua o te "mau" e ngā whenua ke. Nā te tere o te whanaketanga o te umanga taiaho, kua piki haere te aro o te tangata ki te rangahau me te whanaketanga, te whakaputa me te tono taiaho. I roto i ēnei, "He aha te pānga o te taiaho ki te tinana tangata?"
Ko ngā pānga o te hihi laser ki te tinana tangata ko te kino ki ngā kanohi me te kino ki te kiri.
Te kino ki te kiri tangata Nā tōna hanganga ā-tinana, ka taea e te kiri tangata te hanga i tētahi paparanga tiaki katoa, ka taea te whai wāhi tiaki i roto i te oranga o ia rā. Ina nui rawa te kaha o te reera ki te whiti ki te kiri, ka kino te kiko o te kiri. Ahakoa ka taea te whakatika i tēnei kino e te kiko kiri tonu, ka whakaitihia te mahi tiaki o te kiko kiri kua whakatikatikaina. Ko te nui o te kino o te reera ki te kiri ka pāngia nuitia e te nui o te pānga o te reera, te roangaru o te reera, te tae o te kiri me te makuku o te kiko. He maha ngā whakamātautau kua whakaatu he hononga pai te kaha o te reera ki te nui o te kino o te kiko kiri ina whiti te reera ki te kiri. He paepae haumaru mō te mimiti o te kaha reera e te kiri tangata. Ina hipa te paepae haumaru, ka puta te kiri tangata (te wāhanga i whitia e te reera) he whero, he pupuhi, he waro, he kohua, he wera, he mimiti rānei nā te pikinga o te whitinga reera. Ehara i te mea uaua ki te mōhio ko te kino o te reera ki te kiri tangata nā te pānga wera o te reera.
Ahakoa kāore e ranea te kino i puta mai i te hihi laser ki te kiri tangata hei pā ki te hanganga mahi whānui o te kiko kiri, he mea tika tonu kia whakapakarihia te tiakitanga o te kiri tangata i roto i ngā akoranga me te whakamahinga o ia rā, me te mau i ngā kākahu tiaki e hiahiatia ana hei whakaiti i te kino o te hihi laser ki te kiri tangata.
Te kino ki ngā kanohi Ina pāngia te tinana tangata e te hihi laser, koinei te kino tino kino ki ngā kanohi. He tinana porowhita te kanohi tangata, kei roto ko te pakitara o te kanohi, ngā mea kei roto i te karu kanohi, me te retina. Ko te cornea me te sclera, te iris me te choroid, te retina e toru ngā kakano rerekē o te pakitara o te kanohi. Kei roto i ngā mea kei roto i te kanohi ko te tioata, te waiora me te tinana vitreous. Ko te pūnaha whakaata o te karu kanohi ko te cornea me ngā mea kei roto i te kanohi, ā, nā tōna māramatanga, kāore e araia te mārama i te wā e haere ana. Ko te cornea, te iris, te tioata, te tinana vitreous me te waiora ngātahi e hanga ana i te tinana tangata e whiwhi ana i te pūnaha whatu mārama tika. Ko ngā āhuatanga o te pūnaha whakaata he iti te mimiti, he nui te whakawhiti me te kaha ki te arotahi, e āhei ai te hihi laser ki te haere mā te pūnaha whakaata ki te retina ina uru ki te kanohi. I tēnei wā, ka taea te whakanui ake i te kaha o te hihi laser i runga i te retina mā ngā mano, mā ngā tekau mano rānei ngā wā. Ko te pāmahana nui o te retina ka arahi ki te nekrosis o ngā pūtau photoreceptor, ka hua ake he kino kore e taea te whakakore, tae atu ki te matapo tuturu. Ko te kino o te hihi infrared tawhiti ki te kanohi e aro nui ana ki te cornea, ko te hihi ultraviolet ia ka mimitihia e te tioata. Ko te whara o te cornea ka puta te keratitis me te conjunctivitis, ka haere tahi hoki te hunga whara me te wehi o te mārama, te roimata, te ngaro o te tirohanga, te pupuhi me ētahi atu tohu. Ina pakaru te tioata, ka ahua kapua.
I te mea kāore e taea te whakaora i te kino o te karu i puta mai i te hihi laser, me tino aro tātou ki te tiaki i ngā kanohi, me mau mōhiti kanohi, me pupuri i tētahi tawhiti haumaru, me te whai i ngā ture me ngā whakaritenga e tika ana, kia kore ai e whara. I mua i te whakamahinga o te laser mō te mahi, tirohia mēnā he turuturu mārama, me hiri te tūranga e taea ai te turuturu mārama; me pupuri te taiao mahi i te nui o te mārama, me whiriwhiri hoki i ngā hanganga tiaki i hangaia mai i ngā rauemi mimiti mārama; me tirotiro e te tangata ngā mōhiti kanohi haumaru me ngā kākahu tiaki i mua i te mahi me ngā laser. Hei whakarāpopototanga, ka taea e te laser te whakararu nui i te tinana tangata, engari i te nuinga o te wā ka taea e tātou te karo mā roto i ngā tikanga pūtaiao.
