Whakarāpopototia te tuhinga:  E karanga ana ngā tohunga taihara kia whakapakarihia ngā ture mō te taihara kanohi mā te taiaho i muri i te pikinga o ngā tūroro e whiwhi ana i te tiaki kāore i te pai. E ai ki tētahi hōhipera tūmataiti i Harley Street, he tokomaha tonu te hunga e rapu ana i tana āwhina i muri i te whiwhinga i te tohutohu kino, i te tukino kino rānei i tētahi atu wāhi. A e mea ana kua tae ki te wā ki te mahi a te ahumahi ki te mahi. Kei te tono tētahi hōhipera kanohi tūmataiti matua kia kaha ake ngā ture mō te pokanga kanohi mā te taiaho i muri i te kitenga i te pikinga o te tokomaha o ngā tāngata i hoatu i ngā mōhiohio hē, i te tiaki kino rānei. Tae atu ki te 120,000 nga Pakeha e mahi ana i te taatai kanohi laser ia tau hei whakatika i te roa me te tirohanga poto, a tata ki te kotahi i roto i te 20 o ratou e raru ana i etahi momo raruraru. Ko te nuinga o nga mahi e mahia ana i te taha takitahi, me nga tuuroro e utu ana ki te £ 5,000 kia whakatikahia nga kanohi e rua.

I kii a Lois Roberts, he raihana ture, i tino mamae ia i tana pokanga hei whakatika i tana tirohanga poto. I mate ia i te mamae o nga kanohi maroke i muri i tana maimoatanga laser, na te kino o nga uaua e whakaongaonga ana i nga roimata. I ngā tau i muri i te tukanga, ka mea a Miss Roberts me whakamahi ia i ngā maturuturunga kanohi ia rā hei whakaiti i te mamae, e taea ai e ia anō te kawe mai i te mumura o te kanohi. I whakamahia e Miss Roberts ngā arotahi whakapā me ngā karaihe mai i tana kura tuatahi, engari i kitea he raruraru i a ia e mahi hākinakina ana. I whakawhiwhia ki a ia te £1,500 hei waahanga o tana 21 tau i te tau 2010. Engari ehara i te wheako mamae kore i whakaaria mai ki a ia. Ka mea ia: <unk>E pouri ana ahau kāore au i whakatupato tika i taku kōrero tuatahi ka taea e tēnei te tupu. He nui ake taku whakaaro i te mea i mohio ahau ki ngā tūponotanga.<unk> Ko Miss Roberts, no Gwynedd i Te Tai Tokerau o Wales, i mate i te tirohanga pō kino me te "floaters" i nga tau i muri i tana pokanga. "He rite ngā ngārara ki ngā rārangi pango me ngā ira", i kī ia. Kua whakapumautia ahau he harakore ratou, engari he...
He whakatūpato mai i Te Whare Hauora o Ranana i te Ara Harley. Ka puta i muri i te pikinga o ngā tūroro i hoatu i mua i te mōhiohio pōrangi, i te tiaki rānei. I tēnei wā e hiahiatia ana kia rēhitatia anake ngā tohunga taiaho kanohi hei tākuta - ā, kāore he tohu tohunga e hiahiatia ana e te ture.
