Te Whakamārama UV me te Hauora o ngā Kanohi
Ko te rā te pūtake matua o ngā hihi Ultraviolet (UV), ka pā kino pea ki ō kanohi. E toru ngā momo hihi UV e tukuna ana e te rā: UVA, UVB me UVC. Ka mimitia te UVC e te āhuarangi o te Ao; ka āraia te UVB; kāore ngā hihi UVA e tātarihia, nō reira ka pā kino rawa atu ki ō kanohi. Ahakoa he maha ngā momo mōhiti kanohi e wātea ana, kāore ngā mōhiti kanohi katoa e tiaki ana i te UV – he mea nui kia whiriwhiria ngā karaihe e tiaki ana i te UVA me te UVB i te wā e hoko ana i ngā mōhiti kanohi. Ka āwhina ngā mōhiti kanohi ki te ārai i te pānga o te rā ki ngā kanohi, ka arahi pea ki te mate pukupuku kiri, te katarata me ngā kita.
