Mahlaseli a kotsi a tsoang letsatsing a ka baka tshenyo ea mahlo ha u ntse u le moholo - empa o ka sireletsa pono ea hau ka ho roala melase ea litulo letsatsi le leng le le leng, esita le nakong ea leholimo le koahetsoeng. Mona ke seo u lokelang ho se tseba ka ho khetha litela tse ntle ka ho fetisisa, ho thibela li- cataract tse amanang le lilemo le mathata a mahlo ka nako.
Mahlaseli a kotsi le Leihlo le tsofetseng
Ha re ntse re hōla, mahlo a rona a fetoha liphetoho tsa 'mele tse ka bakang mathata a pono le mafu a mahlo a kang bothata bo bakoang ke lilemo-lemo le glaucoma .
Khanya ea letsatsi e tsoang letsatsing e na le mefuta e 'meli ea mahlaseli a kotsi, UVA , le mahlaseli a UVB (e leng se bakang photoaging le wrinkling ea letlalo). Kaha leseli la UV le na le matla a mangata ho feta leseli le bonahalang, le ka senya mahlo a rona haholo. Ha re ntse re hōla, tšenyo e mpa e e-na le nako e eketsehileng ea ho ipokellela: cataract, (cloudiness ea lens) ka mohlala, ho lumeloa hore e bakoa ke lilemo tse ngata tsa ho pepeseha ha letsatsi.
Likhalase tsa mahlaseli tse reretsoeng ho thibela mahlaseli a 100% a UVA le UVB li tla sireletsa mahlo a hao khahlanong le tsenyo ena e kenyang.
Na ho na le Ntho ea Lefifi ea Lense?
Le hoja lilense tse lefifi haholo li ka 'na tsa bonahala li fana ka tšireletso e khōloanyane, lefifi leseli le ama feela leseli le bonahalang, eseng leseli la ultraviolet.
Natalie Hutchings, Moprofesa ea Kenyang Univesithing ea Waterloo's Optometry le Vision Science, o re lensente tse lefifi li ka etsa hore seithuti sa leihlo la hao le be leholoanyane ho lumella hore ho be le leseli le leng, ho etsa hore tšireletso ea UV e be ea bohlokoa le ho feta.
O re ho 'na: " Mmala a lefifi le mmala a lens kapa litlolo hase tsona lintho tse sireletsang mahlo a hao." "Ke habohlokoa haholo ho khetha likhalase tse thibelang lisebelisoa tsohle tsa UV, UVA le UVB ka 100%. Tšireletso ena e ka ba mosebetsi oa boitsebiso ba likhalase, boima ba thepa, kapa e ka 'na ea e-ba seaparo lense - esita le lenseng tse se nang 'mala leha e le ofe.
Ke thibelo ea UV ea 100% eo u lokelang ho e sheba holim'a letšoao, kaha u ke ke ua bolela hore na ba na le eona, feela ka ho sheba likhalase. "
Litlhahiso Bakeng sa ho Khetha Lilala tsa Meremo tse Molemohali ho Thibela Likotsi le Lintho Tse Ling Tsa Mahlo
Ho ea ka American Academy of Ophthalmology (AAO), litebelisoa tse ntle ka ho fetisisa tsa mahlaseli a letsatsi li fana ka:
- Tšireletso ea 100% ea UV
- Tšobotsi e phahameng ea optical (lensisi ha e na litšitiso tse hlahisoang joaloka maqhubu kapa maqhubu a ka utloisang mahlo a hao bohloko
- Li-lense tse hanyetsang
- Setamo se seholoanyane se fanang ka boitsebiso bo bongata ba mahlo
Ho phaella moo, khetha litula tsa mahlaseli tse phutholohileng le tse lumellanang le sefahleho sa hau hantle, hobane u tla ba le tšekamelo ea ho li apara. Hutchings e fana ka maikutlo a hore batho ba baholo ba ka 'na ba khetha liforeimi tse khōloanyane, tse matla tseo ho leng bonolo ho li sebetsana le menoana ea ramatiki.
Katleho ea li-lense tsa polarized
Hutchings e re lilense tse nang le polarized li sebetsa ka leseli le bonahalang (eseng mahlaseli a kotsi), ka ho thibela khanya e khanyang e bonts'itsoeng ka holim'a lehloa, metsi kapa tsela e chesang. Nahana ka lilense tsa polarized haeba u palama, phela haufi le metsi, kapa u li fumane li phutholoha ha u ntse u khanna. Le hoja lenses tsena li atisa ho theko e boima, u ka fumana u li khetha ha u ntse u hōla.
Ha U Lokela ho apara Lilala tsa Lirala ho Sireletsa Mahlo a Hao
AAO e khothalletsa ho apara litula tsa mahlaseli nako leha e le efe ha u le ka ntle, haholo-holo lehlabula, ha mahlaseli a mahlaseli a kotsi a le makhetlo a mararo a linako tse ling tsa selemo.
Ho phaella moo, o lokela ho hlokomela ho apara mabone a silevera ha a le ka metsing kapa lehloa, ha mahlaseli a khanyang a bonahala.
Batho ba baholo ba ka 'na ba fumana hore ba hloka ho apara likhalase tsa mahlaseli hangata ho feta kamoo ba neng ba tloaetse kateng, ho bolela Natalie Hutchings, hobane leseli le fetang har'a cornea le lense le hasane ho isa tekanyo e kholo ho leihlo la botsofali. Tšenyo ena e ka ba e sitisang le e halefisang, empa e fokotsoa ka tšebeliso ea litela tsa mahlaseli, haholo-holo tse khōloanyane tse thibelang leseli le tsoang mahlakoreng.
Ho apara litulo tsa litulo kamora 'meriana oa Cataract
Nakong ea ho buuoa ke cataract , lense e ncha ea intraocular (IOL) e kenngoa ho nka sebaka sa lense ea khale.
Boholo ba lensisi tsa li-intraocular hona joale bo amohela leseli la UV. Haeba u ne u e-na le ho buuoa ha hao ka cataract nako e fetileng, lense ea hao e ka 'na ea se ke ea amohela leseli la UV,' me u lokela ho apara lisele tsa lisele tse fanang ka tšireletso. AOO e khothalletsa esita le batho ba nang le lilense tse ntšang mahlaseli a kotsi ka mor'a hore ba buuoe ke lefu la lik'hemik'hale ba roala melase ea ho sireletsa.
Litsela Tse Ling tsa ho Sireletsa Mahlo a Hao ho Letsatsi
Likhalase tsa letsatsi li fana ka mofuta o le mong feela oa tšireletso bakeng sa mahlo a botsofali. Bophelo bo botle ba Canada le mekhatlo e meng e eletsa le ho apara sekoti kapa sephara se seholo ha u le ka ntle 'me u qoba linako tse khanyang le tse matla ka ho fetisisa, tse kang matsatsi a lehlabula pakeng tsa lihora tsa 11 ho isa ho tse 4 mantsiboea ).
