Ko te ngenge tirohanga he rōpū tohu e nui ake ai te titiro a te kanohi ki ngā mea i tua atu i te kaha o tana mahi tirohanga nā runga i ngā take maha, ka puta he ngoikoretanga tirohanga, he mamae kanohi, he tohu pūnaha rānei i muri i te whakamahi i ngā kanohi.。
E ai ki ngā rangahau mate urutā, 23% o ngā tamariki kura, 64% ~ 90% o ngā kaiwhakamahi rorohiko, me 71.3% o ngā tūroro kanohi maroke, he rerekē ngā tohu o te ngenge tirohanga.
Nā, me pēhea te whakaiti, te ārai rānei i te ngenge o te tirohanga??
1. Kai taurite
He mea nui ngā āhuatanga kai hei whakahaere i te puta o te ngenge tirohanga. Mā te tāpiringa kai tika o ngā matūkai e tika ana ka ārai, ka whakaroa hoki i te putanga mai me te whanaketanga o te ngenge tirohanga. He pai ki ngā taiohi te kai i ngā kai mātotoru, i ngā inu me ngā kai tere. He iti te uara kai o tēnei momo kai, engari he nui ngā kaora. Me whakahaere te kai o ēnei kai. Kia iti ake te kai i ngā mea ka tangohia, kia nui ake te tunu kai, ā, me kai i te kai taurite.。
2. Kia tūpato ki te whakamahi i ngā pata kanohi
He rerekē ngā whakamahinga o ngā pata kanohi, pērā i te rongoā i ngā mate kanohi, te whakaiti i te pēhanga o roto o te kanohi, te whakamamae i te mumura me te mamae, te whakamamae rānei i ngā kanohi maroke. Pērā i ētahi atu rongoā, he maha ngā pata kanohi he pānga taha. Ko te whakamahinga pinepine o ngā pata kanohi ehara i te mea ka whakawhirinaki noa ki ngā rongoā, ka whakaiti i te mahi horoi-ake o ngā kanohi, engari ka kino hoki ki te cornea me te conjunctiva. Ko ngā pata kanohi kei roto ngā matū patu huakita ka ārai pea i ngā huakita i roto i ngā kanohi ki ngā rongoā. Kia puta he mate kanohi, ehara i te mea ngāwari ki te rongoā.
3. Te tohatoha tika o ngā hāora mahi
Kua whakaatuhia e ngā rangahau ka taea e ngā wā okiokinga auau te whakaora i te pūnaha whakahaere o te kanohi. Hei whai i te ture 20-20-20, me okioki 20 hēkona mai i te mata i ia 20 meneti. E ai ki ngā wā tirotiro kanohi, i hangaia e te tohunga kanohi o California a Jeffrey Anshel he ture 20-20-20 hei āwhina i te okiokinga me te ārai i te ngenge o te kanohi. Arā, me okioki i ia 20 meneti o te whakamahi i te rorohiko, ka titiro ki te tirohanga (he pai ake te matomato) 20 putu (tata ki te 6m) te tawhiti mō te iti rawa 20 hēkona.
4. Mauria ngā karaihe ārai-ngoikore
He hoahoa kore-taurite te arotahi ārai-ngoi o te Universe Optical, ka taea te whakapai ake i te mahi whakakotahi tirohanga rua-kanohi, kia taea ai te whakaatu i te tirohanga whānui me te whakamāramatanga teitei ina titiro tata, ina titiro tawhiti hoki. Mā te whakamahi i te mahi whakatikatika āwhina tata ka taea te whakaiti i ngā tohu o te maroke o ngā kanohi me te ānini e puta mai ana i te ngenge tirohanga. Hei tāpiri, e toru ngā momo rama iti o te 0.50, 0.75 me te 1.00 kua hangaia mō ngā momo tāngata katoa hei whiriwhiri, ka taea te whakaiti i te ngenge tirohanga e puta mai ana i te whakamahinga roa o ngā kanohi, ā, ka taea hoki te whakatutuki i ngā momo kaimahi tata katoa, pērā i ngā ākonga, ngā kaimahi kara-mā, ngā kaipeita me ngā kaituhi.
He poto te wā urutau o te karaihe whakaata o te Universe optical relief for tightness mō ngā kanohi e rua. He tino pai mō te hunga tīmata. He karaihe mahi tēnei e wātea ana ki te katoa. Ka taea hoki te tāpiri atu ki ngā hoahoa motuhake pērā i te ātete pānga me te ātete mārama kikorangi hei whakaoti i te raruraru o te ngenge tirohanga.
