Mokhoa oa 1. Sheba letšoao la likhalase tsa letsatsi.
Matšoao a bonahalang a kang "UV protection", "UV400", joalo-joalo a bonoa lileiboleng kapa lilenseng tse hanyetsanang le UV.likhalase tsa letsatsi."UV index" ke phello ea ho sefa mahlaseli a ultraviolet, e leng mokhoa oa bohlokoa oa ho reka likhalase tsa letsatsi.Leseli le nang le leqhubu la bolelele ba 286nm-400nm le bitsoa leseli la ultraviolet.Ka kakaretso, index ea UV ea 100% ha e khonehe.Lenane la UV la likhalase tse ngata tsa letsatsi le pakeng tsa 96% le 98%.
Likhalase tse nang le anti-ultraviolet hangata li na le mekhoa e latelang e hlakileng:
a) Tšoaea "UV400": sena se bolela hore bolelele bo khaotsoeng ba lense ho khanya ea ultraviolet ke 400nm, ke hore, boleng bo phahameng ka ho fetisisa τmax (λ) ea phetisetso ea spectral boteleleng ba maqhubu (λ) ka tlase ho 400nm ha e fete. 2%;
b) Tšoaea "UV" le "ts'ireletso ea UV": sena se bolela hore bolelele bo khaotsoeng ba lense ho ea ho ultraviolet ke 380nm, ke hore, boleng bo phahameng ka ho fetisisa τmax(λ) ba phetisetso ea spectral boteleleng ba maqhubu (λ) ka tlase ho 380nm. ha e fete 2%;
c) Tšoaea "100% UV absorption": Sena se bolela hore lense e na le ts'ebetso ea 100% ea ho monya mahlaseli a ultraviolet, ke hore, phetisetso ea eona e tloaelehileng ea mahlaseli a ultraviolet ha e kholo ho feta 0.5%.
