Ko te hītori o ngā mōhiti kanohi ka taea te whai i ngā tau 14thI Haina i te rautau -100, i whakamahia ai e ngā kaiwhakawā ngā mōhiti i hangaia ki te quartz auahi hei huna i ō rātou kare ā-roto. E 600 tau i muri mai, i whakaurua tuatahitia e te kaipakihi a Sam Foster ngā mōhiti kanohi hou e mōhiotia ana e tātou i ēnei rā i Atlantic City. Mai i taua wā, ka tū te Rā Mōhiti Titiro i ia tau i te 27 o Hune. Ko te whāinga o ngā huihuinga ā-tau he hora i te mōhiotanga mō te hiranga o te mau mōhiti kanohi hei tiaki i te hihi ultraviolet.

Me pēhea taku mōhio mēnā he ārai UV kei roto i ngā mōhiti kanohi? Heoi anō, ehara i te mea ngāwari ki te mōhio mēnā he karāhe ārai UV kei roto i ō mōhiti kanohi mā te titiro noa iho. Kāore hoki e taea te wehewehe i te nui o te tiakitanga i runga i te tae o te karāhe, nā te mea kāore he pānga o ngā tae karāhe ki te ārai UV.
