Na ho Hlokahala ho Apara Likhalase tsa Letsatsi Mariha?

Mariha a tla, na hoa hlokahala ho roala likhalase tsa letsatsi?
Ho fihla ha mariha ho bolela boemo ba leholimo bo pholileng le khanya ea letsatsi e batlang e le bonolo. Nakong ena ea selemo, batho ba bangata ba ikutloa hore ho roala likhalase tsa letsatsi ho ka ’na ha se sa hlokahala hobane letsatsi ha le chese joaloka lehlabula. Leha ho le joalo, ke nahana hore ho roala likhalase tsa letsatsi ho ntse ho hlokahala nakong ea likhoeli tsa hoetla le mariha.

Pele ho tsohle, likhalase tsa letsatsi ha li sebelisetsoe feela ho thibela mahlaseli a letsatsi, empa habohlokoa le ho feta, li sebelisetsoa ho sireletsa mahlo mahlaseling a ultraviolet. Le hoja letsatsi le batla le fokola mariha, mahlaseli a kotsi a ntse a le teng ’me a ka senya mahlo a rōna. Ho pepeseha ha nako e telele mahlaseling a ultraviolet ho ka lebisa ho hlaheng ha mafu a mahlo a kang lens maculopathy, cataracts, le ho senyeha ha macular holim'a leihlo la leihlo. Ka hona, ho aparalikhalase tsa letsatsie ka re thusa ka katleho ho fokotsa tšenyo ea mahlaseli a kotsi le ho sireletsa bophelo ba mahlo.

Taba ea bobeli, ho khetha likhalase tse loketseng tsa letsatsi ho bohlokoa haholo bakeng sa bophelo bo botle ba mahlo. Mariha le hoetla, ka lebaka la boemo ba leholimo bo pholileng, hangata ho na le menyetla e mengata ea mesebetsi ea ka ntle, e kang ho tsamaea, ho tsoa, ​​joalo-joalo Nakong ea mesebetsi ena, mahlo a rona a pepesehela ho tsosoa ha moea o batang le lehlabathe le nang le moea. Ho roala likhalase tsa letsatsi ho ka fana ka tšireletso e molemonyana mahlong a rōna. Hoa hlokahala ho khetha likhalase tsa letsatsi tse nang le ts'ebetso e lekaneng ea tšireletso. E ke ke ea thibela feela tšenyo ea mahlaseli a ultraviolet, empa hape e fokotsa ho tsosoa ka ho toba ha moea, lehlabathe le lintho tse tsoang linaheng tse ling, le ho sireletsa mahlo ho tloha tikolohong e ka ntle.

Joale, u ka khetha likhalase tse nepahetseng joang? Pele ho tsohle, re lokela ho khetha likhalase tsa letsatsi tse nang le tekanyo e itseng ea tšireletso ea UV. Hangata, likhalase tse tloaelehileng tsa letsatsi li tla tšoauoa ka aUV400tšoaea lense, ho bolelang hore a ka thibela mahlaseli a ultraviolet ka bolelele ba maqhubu a ka tlase ho li-nanometer tse 400.

Ho phaella moo, o ka khetha likhalase tsa letsatsi kamosebetsi oa polarized, e ka sefang khanya e benyang le ho fana ka pono e hlakileng haholoanyane le e phutholohileng haholoanyane.

Hase hoo feela, ponahalo ea likhalase tsa letsatsi le tsona ke ntlha e lokelang ho nahanoa. Ho khetha likhalase tse feshene le tse fesheneng ho ke ke ha bapala karolo ea mokhabiso feela, empa hape ho totobatsa botho ba hau.
Ho akaretsa, hoa hlokahala ho roala likhalase tsa letsatsi ha u tsoa ka hoetla le mariha. Likhalase tsa letsatsi li ka sireletsa mahlo a hao mahlaseling a ultraviolet hape li ka fokotsa ka katleho ho teneha ha mahlo ke moea, lehlabatheng le moea o batang. Ho khetha likhalase tse loketseng tsa mahlaseli ha lia lokela ho sireletsa feela mahlaseli a ultraviolet, empa hape li lumellane le mekhoa ea feshene, e le hore u ka sireletsa mahlo a hao ha u ntse u bontša botle ba hau joaloka fashionista.

Haeba u batla ho tseba haholoanyane ka mekhoa ea feshene ea likhalase le lipuisano tsa indasteri, ka kopo etela sebaka sa rona sa Marang-rang 'me u ikopanye le rona neng kapa neng.
