Ho se utloisisane 1:
Likhalase tsohle tsa letsatsi li hanyetsa UV ka 100%.
A re qaleng ka ho utloisisa leseli la ultraviolet.Bophahamo ba maqhubu a khanya ea ultraviolet bo ka tlase ho 400 uv.Ka mor'a hore leihlo le hlahisoe, le tla senya cornea le retina, e leng se hlahisang keratitis ea letsatsi le tšenyo ea corneal endothelial.Likhalase tsa mahlaseli tsa boleng bo phahameng li lokela ho khona ho monya kapa ho bonahatsa mahlaseli a ultraviolet ho thibela ho pepeseha ha mahlo.
Likhalase tse nang le anti-ultraviolet hangata li na le mekhoa e 'maloa e hlakileng:
1. Tšoaea “UV400″:
Ho bolela hore bolelele ba ho itšehla thajana ba lense ho ea ho mahlaseli a ultraviolet ke 400nm, ke hore, boleng bo phahameng ba phetisetso ea eona ea spectral ka leqhubu le ka tlase ho 400nm e ke ke ea ba kholo ho feta 2%.
2. Tšoaea "UV", "Tsireletso ea UV":
E bontša hore bolelele bo thibelang ba lense khahlanong le mahlaseli a ultraviolet ke 380nm.
3. Tšoaea "100% ea ho monya UV":
Ho bolela hore lense e na le 100% e monyang mahlaseli a ultraviolet, ke hore, karolelano ea phetisetso ea mahlaseli a kotsi ha e fete 0.5%.Ka kakaretso, ke ba nang le matšoao a boletsoeng ka holimo feela ba ka nkoang e le likhalase mosebetsi o sireletsang khahlanong le mahlaseli a ultraviolet ka kutloisiso ea 'nete.
Ho se utloisisane 2:
Likhalase tsa mahlaseli tsa polarized li molemo ho feta likhalase tse tloaelehileng
Likhalase tse bitsoang polarized sunglasses, ntle le mesebetsi ea likhalase tsa letsatsi, li ka fokolisa le ho thibela bohlasoa.
khanya e phatsimang, likhase tse sa tloaelehang tsa lintho, joalo-joalo, 'me e fetisetsa tsela e nepahetseng ho ea tseleng.
leihlo la ho bona ka mahlo a kelello le ho etsa hore pono e be le Maemo a ruileng, pono e hlakile haholoanyane le ea tlhaho.Li-polarizers hangata li joalo
e loketseng mesebetsi ea ka ntle e kang ho khanna, ho tšoasa litlhapi, ho tsamaea ka sekepe, whitewater rafting, le skiing.Joaloka 'mala oa
lilense tsa polarizer hangata li lefifi, ha ho hlokahale ho li apara matsatsing a maru kapa ka tlung.U lokela ho khetha
likhalase tse ling tse tloaelehileng ho sireletsa mahlo a hau mahlaseling a ultraviolet.
