• Ubumfama bekhephu: Eli ligama elinikwe imeko ye-photokeratitis eyenzeka xa ukukhanya kwelanga kukhanya phezu kwekhephu kubetha amehlo kwiindawo ezinekhephu. Umoya kwiindawo ezineentaba uncinci, ngoko ke akukho khuselo luninzi kwimitha ye-UV, ngoko ke le ngozi iphezulu.

• Izixhobo zokuwelda: Ukukhanya okunamandla okuveliswa ngexesha lokuwelda (ukuwelda kwe-arc).
• Iibhedi zokuthambisa ulusu: Izibane ezisetyenziselwa ukuthambisa ulusu.
• Ezinye iintlobo zezibane: Ezinye izibane ezifana nezibane zomphunga we-mercury, izibane zedesika ze-halogen.
• Ukukhanya kwezonyango: Imithombo yokukhanya ye-UV ekhethekileyo esetyenziselwa ukubulala iintsholongwane okanye unyango oluthile.

Ngubani osengozini enkulu?

Unamathuba amaninzi okuba nale meko ukuba:

• Ukuba uchitha ixesha elininzi ngaphandle elangeni, uthatha inxaxheba kwimisebenzi efana nokuhamba intaba, ukutyibiliza eqhweni, okanye ukudada.
• Ukuba usebenza kumsebenzi obandakanya ukusebenza ngemithombo yokukhanya kwe-UV, efana nokuwelda .
• **Ukuba uhlala kwindawo ephakamileyo.

Ngaba oku kunokuba nemiphumo yexesha elide?

I-Photokeratitis idla ngokuba yimeko yexeshana, kodwa ukuqhubeka uchaphazeleka nokuba kuncinci kangakanani na kwimitha ye-UV kunokubangela iingxaki zexesha elide.

• I-Cataract: Ukufiphala kwelensi yeliso.
• Ukonakala kweMacular: Ukulahlekelwa yimbono ephakathi njengoko ukhula.
• Ukukhula kwezicubu kumphezulu weliso: Ukukhula kwezicubu kumphezulu weliso, njenge-'pingueculae' kunye ne-'pterygia', kunokwenzeka. Ezi zinokuthintelwa ngokunxiba iiglasi zelanga.

Kwakhona, khumbula ukuba ukukhanya okuluhlaza okwesibhakabhaka nokumfusa okukhutshwa zizibane ze-LED, iikhompyutha, kunye neefowuni eziphathwayo nako kunokuba yingozi kwi-retina ekuhambeni kwexesha.
