Re kenyelletsa lihlahisoa tseo re nahanang hore li na le thuso ho babali ba rona. Haeba u reka ka lihokela tse leqepheng lena, re ka fumana khomishene e nyane. Ts'ebetso ea rona ke ena.

Ke mang ea sebelisang lilense tse ntlafalitsoeng?

Lilense tse senyehileng ke khetho e ntle ho mang kapa mang ea qetang nako a le kantle. Haeba u sebetsa kantle, haholo ha o etsa mesebetsi e phatsimang haholo haufi le metsi kapa lehloa, lilense tse khantšitsoeng li thusa ho fokotsa lehlaseli le ho fana ka ho hlaka ho eketsehileng ha mahlo a hao a ntse a sirelelitsoe.

Ho na le likhetho tse ngata tse fapaneng bakeng sa ho sireletsa mahlo a hau le lilense tse ntlafalitsoeng ke monyetla o le mong feela. Feela joaloka ho sireletsa letlalo la hao haeba u qeta lihora u le letsatsing, mahlo a hao a hloka tšireletso.

Melemo ea lilense tse ntlafalitsoeng

• pono e hlakileng, haholo-holo ka khanya e khanyang
• phapang e eketsehileng le ho sotha mmala ho fokolang
• fokotseha leihlo le ponahatso
• phokotso ea mahlo

Melemo ena e etsa lilense tse ntlafalitsoeng hantle bakeng sa likhalase tsa letsatsi. Li phethehile ho mang kapa mang ea sebelisang nako e ngata kantle, 'me li ka thusa ho ntlafatsa pono ea hau maemong a phatsimang haholo.

Leha ho le joalo, hobane seaparo se khabisitsoeng se boetse se fifatsa lense, lilense tse polarized ha li fumanehe bakeng sa likhalase tsa ho bala tse tloaelehileng.

Likotsi tsa lilense tse ntlafalitsoeng

Le ha lilense tse ntlafalitsoeng li le ntle bakeng sa ho sireletsa mahlo a hau ho leseli le khanyang le ho fokotsa lehlaseli, ho na le litšitiso tse ling.

• ho sheba li-skrini tsa LCD
• ho fofa
• maemo a lebone le tlase le ho kganna bosiu
• batho bao mahlo a bona a ka utloang tsela eo lilense li fetolang mabone ka eona

Lilense tse polarized li ka etsa hore ho be thata ho bona li-skrini tsa LCD. Haeba ho le bohlokoa ho bona dashboard kapa skrini bakeng sa mabaka a polokeho kapa boiketlo, lilense tse khabisitsoeng e kanna ea se be khetho e ntle ho uena.

Ho feta moo, ba ka arabela hampe lithutong tse ling lifensetereng tsa moea, ho bolelang hore ha se khetho e ntle ka ho fetesisa ea ho khanna.

E-ba hlokolosi ka lipolelo mabapi le melemo ea ho roala lilense tse benyang kapa tse tlotsitsoeng bosiu. Ka linako tse ling lilense tse benyang li loketse ho khanna motšehare, empa ho li apesa bosiu ho ka ba kotsi.

Lense e fifetseng e etsa hore ho be thata ho bona maemong a fokolang, a ka mpefalang haeba o se o na le bothata ba ho bona bosiu.

Haeba u sa tsebe hantle hore na u lokela ho leka lilense tse polarized, leka ho bua le ngaka ea mahlo mabapi le hore na ke mefuta efe ea likhalase tse sireletsang tse u loketseng le mahlo a hao.

Lilense tse ntlafalitsoeng li sebetsa joang

Lilense tse khantšitsoeng li sebetsa ka ho thibela mahlaseli a khanyang hore a se u otle ka ho toba ka leihlong. Pono e etsahala ha leihlo la hao le bona mahlaseli a khanya a hlahisang ntho. Ka tloaelo, leseli leo le hasana ka tsela e itseng pele le kena ka leihlong la hao.

E tloaetse ho hlasela maqhubu a mangata ka lebaka la bokaholimo ba ntho, joalo ka letlalo kapa lefika. Mabone a boreleli, a bataletse, a benyang haholo joalo ka metsi, tšepe kapa lehloa, khanya e khanya haholoanyane. Lebaka ke hore e itlhahisa ka kotloloho ka leihlong ntle le ho hasana.

Ka ho roala lilense tse polarized ka k'hemik'hale e khethehileng, li thiba leseli le leng ha le feta ho tsona. E sebetsa joalo ka sefahla sa se bonts'ang ka kotloloho mahlong a hau.

Ka lilense tse ntlafalitsoeng, sefahleho se otlolohile, kahoo ke khanya e 'ngoe feela e ka fetang mabeneng. Hobane glare hangata ke leseli le otlolohileng, lilense tse khantšitsoeng li thibela leseli lena mme li lumella leseli le emeng feela. Ha leseli le otlolohileng le koetsoe ke lilense tse polarized, sena se thusa ho felisa mahlaseli a tsoang ho khanya ka ho toba mahlong a hau.

Reka likhalase tsa mahlaseli tsa letsatsi marang-rang.

Mekhoa e meng ea lilense tse ntlafalitsoeng

Batho ba bang ba kanna ba fumana likhalase tse polarized li sa phutholoha kapa ba ka sitoa ho li roala ka lebaka la mosebetsi oa bona. Haeba o sa khone ho roala lilense tse polarized ka lebaka lefe kapa lefe, ho na le mekhoa e meng e fumanehang:

• Ho roala lintho tse loantšang mahlo ho a fumaneha bakeng sa likhalase tsa letsatsi le likhalase tsa ho bala.
• Likhalase tsa mahlaseli tse khantšitsoeng li thusa ho fokotsa hore na khanya e kenella mahlong a hau hakae.
• Lilense tsa photochromic ka botsona lia fifala ha li pepesetsoa khanya e itseng.

Lilense tse polar khahlanong le ts'ireletso ea UV

Lilense tse polariloeng le lilense tse sirelelitsoeng ka UV ha se ntho e le 'ngoe. Kahoo, ho bohlokoa ho hopola hore lilense tse polarized ha li fane ka tšireletso ea UV ntle leha e ngotsoe ka tsela e ngoe.

Tšireletso ea UV feela ha e etse hore likhalase tsa mahlo li sebetse hantle khahlano le mahlaseli a khanya le mahlaseli.

Lilense tse sirelelitsoeng ke UV li sebetsa ka ho sireletsa mahlo a hau khahlano le kotsi e hlahisoang ke UV, e amanang le lera la mahlo le tšenyo ea mahlo. Le ho pepesetsoa lebone le bohale la UV nako e khuts'oane ho ka baka bofofu ba nakoana, kapa photokeratitis. Ho bohlokoa ho lula u roala likhalase tsa mahlo tse nang le 99 kapa 100% UV tšireletso ha u le kantle.

Leha ho le joalo, kaha lilense tsa UV ha li thibele ho phatsima, o lokela ho sheba likhalase tsa letsatsi tse polarized mme li fana ka ts'ireletso ea UV.

Ho latela American Academy of Ophthalmology, likhalase tsa mahlaseli tse ngata tse khabisitsoeng 'marakeng li kenyelletsa seaparo sa ts'ireletso ea UV. Etsa bonnete ba hore u bala li-tag likhalase tsa mahlaseli nakong e tlang ha u ntse u reka para.

Ho lemoha lilense tse polarized

Ho bonolo haholo ho tseba hore na likhalase tsa hau tsa letsatsi li silafalitsoe. Leka ho sheba bokaholimo bo bonahatsang le ka ntle le lilense. Lilense tse khantšitsoeng li sebetsa ka ho fokotsa lehlaseli le tsoang maboneng a khanyang le holim'a phapang e nyane, kahoo li lokela ho etsa hore ho be bonolo ho bona lintho ka khanya e khanyang.

Tsela e 'ngoe ea ho lekola lilense tse ntlafalitsoeng ke ka ho sheba skrineng sa LCD. Polarization hangata e ka etsa hore ho be thata haholo ho bona li-skrini ho feta ka lilense tse tloahelehileng. Ka lilense tse ntlafalitsoeng, li-skrini tsa LCD li shebahala li le ntsho kapa li le lefifi haholo.

Tsela

Lilense tse silafalitsoeng ke khetho e ntle ho mang kapa mang ea sebelisang nako e ngata kantle. Ha se feela hore li fokotsa ponahalo e khanyang le mahlaseli a sa batleheng, lilense tse khantšitsoeng li boetse li thusa ho ntlafatsa pono e hlakileng maemong a khanyang.

Hopola, likhalase tse khantšitsoeng tse khantšitsoeng li ke ke tsa u sireletsa hore u se ke ua sheba ka ho toba letsatsing. Kamehla o lokela ho nka mehato ea ho itšireletsa ho sireletsa mahlo a hau ho leseli le kotsi la UV, leha e se khanya e kantle haholo.

Ha u reka likhalase tsa mahlo, u se ke ua nahana feela ka chebahalo. Lilense tse khantšitsoeng ke e 'ngoe ea likhetho tse' maloa tsa likhalase tsa letsatsi tseo u tlamehang ho li boloka li phetse hantle letsatsing.
