Ha boemo ba leholimo bo ntse bo futhumala, u ka ’na ua iphumana u qeta nako e ngata u le ka ntle.E le ho sireletsa uena le lelapa la hao boemong ba leholimo, likhalase tsa letsatsi li tlamehile!
Ho pepeseha ha UV le Bophelo bo Botle ba Mahlo
Letsatsi ke mohloli o ka sehloohong oa mahlaseli a Ultraviolet (UV), a ka bakang tšenyo mahlong a hau.Letsatsi le ntša mefuta e 3 ea mahlaseli a UV: UVA, UVB le UVC.UVC e monngoa ke sepakapaka sa Lefatše;UVB e koetsoe ka mokhoa o itseng;Mahlaseli a UVA ha a hloekisoe, ka hona a ka baka tšenyo e kholo mahlong a hau.Le hoja mefuta e mengata ea likhalase tsa letsatsi e le teng, ha se likhalase tsohle tse fanang ka tšireletso ea UV - ho bohlokoa ho khetha lilense tse fanang ka tšireletso ea UVA le UVB ha u reka likhalase.Likhalase tsa letsatsi li thusa ho thibela ho pepeseha ha letsatsi ho pota-pota mahlo ho ka lebisang ho kankere ea letlalo, lera la mahlo le masoebe.Likhalase tsa letsatsi le tsona ke tšireletso ea pono e sireletsehileng ka ho fetisisa bakeng sa ho khanna 'me e fana ka bophelo bo botle ka kakaretso le ts'ireletso ea UV bakeng sa mahlo a hau kantle.
Ho Khetha Likhalase Tsa Letsatsi tse Nepahetseng
Le hoja setaele le boiketlo li phetha karolo e kholo tabeng ea ho khetha likhalase tse nepahetseng tsa letsatsi, lilense tse nepahetseng le tsona li ka etsa phapang e khōlō.
- Tintedlense: Mahlaseli a UV a teng selemo ho pota, haholo-holo likhoeling tsa lehlabula.Ho roala likhalase tsa letsatsi tse fanang ka tšireletso ea 100% UV ke e 'ngoe ea litsela tse bonolo ka ho fetisisa tsa ho fokotsa likotsi tse ngata tsa bophelo bo botle ba mahlo.Empa ka kopo hlokomela hore lilense tse lefifi ha li fane ka tšireletso e eketsehileng.Batla tšireletso ea 100% UVA / UVB ha u reka likhalase tsa letsatsi.
- Lense ea polarized:Lithapa tse fapaneng tsa lense li ka ba molemo bakeng sa mesebetsi e fapaneng.Likhalase tsa mahlaseli tsa polarized li ke ke tsa u sireletsa feela mahlaseling a UV, empa hape li thusa ho fokotsa ho benya le ho bonahatsa bokaholimo bo joalo ka metsi.Kahoo likhalase tsa mahlaseli tsa Polarized li tumme bakeng sa ho palama likepe, ho tšoasa litlhapi, ho palama libaesekele, kolofo, ho khanna le mesebetsi e meng ea kantle.
- Mirror Coating e Fumaneha ka Lense ea Tinted&Polarized:Lilense tse entsoeng ka seipone li fana ka tšireletso ea UV le khanya ka khetho ea mebala ea seipone ea feshene.
Tšireletso ea letsatsi e bohlokoa selemo ho pota mme ts'enyo ea UV e ntse e eketseha bophelong ba hau.Ho roala likhalase tsa letsatsi letsatsi le letsatsi ha u tsoa ka monyako ke mokhoa o bonolo le o bonolo oa ho tšehetsa bophelo ba mahlo a hau.
