Ukubaluleka kokukhusela ilanga kwamehlo
Ihlobo lilapha, kwaye ukukhuselwa kwelanga kubalulekile xa ujongene nemozulu ephezulu ye-ultraviolet. Nangona kunjalo, xa kuziwa ekukhuselweni kwelanga ehlobo, abantu abaninzi bagxila kuphela esikhumbeni kwaye bawahoxise amehlo. Ngapha koko, amehlo, njengenxalenye eethe-ethe kakhulu yomzimba womntu, achaphazeleka ngakumbi kumonakalo we-ultraviolet kunolusu. Ukutshatyalaliswa kwexesha elide kwimisebe ye-ultraviolet kwandisa umngcipheko wezifo zamehlo ezifana ne-cataract kunye ne-macular degeneration. Ukongeza, imisebe ye-ultraviolet ikhawulezisa ukuguga kwesikhumba ejikeleze amehlo, ekhokelela kwiingxaki ezinjengemibimbi kunye nezangqa ezimnyama. Ukunxiba iindondo zokukhusela ilanga kunokunciphisa umngcipheko wokwaluphala kolusu. Ngexesha elifanayo, kwindawo enamandla yokukhanya kwelanga, amehlo kufuneka ahlale elungelelanisa utshintsho ekukhanyeni, okunokubangela ukukhathala kwamehlo kunye nokungahambi kakuhle. Ukunxiba iindondo zelanga kunokuphelisa oku kukhathazeka.
Umonakalo we-ultraviolet emehlweni
Imitha yemitha yeUltraviolet (UV) ivela elangeni yaye luhlobo oluthile lokukhanya olungabonakaliyo ngeliso lenyama. Yahlulwe yaba ziindidi ezintathu: UVA, UVB kunye neUVC. Phakathi kwazo, iUVA neUVB zinokungena kumoya ojikeleze umhlaba zize zichaphazele ulusu namehlo ethu. Ehlotyeni, ngokunyuka kwexesha lokukhanya kwelanga kunye nokutshintsha kwexesha kwi-ozone layer, ubukhulu bemitha ye-ultraviolet bufikelela kwincopho yalo ngonyaka. Ngoko ke, kubaluleke kakhulu ukukhusela amehlo kumonakalo we-ultraviolet.
1. Yandisa ingozi yorhatyazo
Ukubonakaliswa kwexesha elide kukukhanya okunamandla kwe-ultraviolet kunokubangela ukuba iprotheni kwilensi yeliso ibe yi-denature, ekhokelela kwi-turbidity kunye ne-cataract. Esi sisifo samehlo esingaboniyo esichaphazela kakhulu umbono.
2. Unobangela pterygium
Ukukhanya kwe-Ultraviolet kunokuvuselela ukukhula okungaqhelekanga kwezicubu kumphezulu weliso, ukwenza i-pterygium, i-pinki, i-triangular tissue hyperplasia eyenziwe kumphezulu we-eyeball, echaphazela ukubonakala kwaye inokuthintela umbono kwiimeko ezinzima.
3. Umonakalo kwiretina
Imitha yeUVB inokonakalisa ngokuthe ngqo iiseli zeretina, yaye ukuqokelelana kwethu ixesha elide kunokwandisa ingozi yokuwohloka kwemacular, isifo esibangela ukuncipha okanye kwanokubona kakuhle.
4. I-syndrome yeso elomileyo
Ukukhanya kwe-Ultraviolet kunokwenza ukoma komphezulu we-ocular, kunciphise ukukhuselwa kweenyembezi, kwaye kubangele okanye kwandise iimpawu zamehlo ezomileyo, ezinje ngamehlo omileyo kunye nokuziva okutshisayo.
Ngawaphi amanyathelo okukhusela ilanga?
1. Nxiba iindondo zelanga
Kubalulekile ukukhetha iindondo zelanga ezinokuthintela i-100% yemitha ye-UVA kunye ne-UVB. Qaphela ukuba ubunzulu bombala abumeli ngokuthe ngqo ukukwazi ukuvimba ukukhanya kwe-ultraviolet. Undoqo kukukhangela ukuba kukho ilogo ethi "UV400" okanye "100% yoKhuseleko lweUV".
2. Nxiba umnqwazi onomphetho obanzi
Ukunxiba umnqwazi onomphetho obanzi kunokubonelela ngomthunzi ngakumbi ebusweni kunye namehlo ukusa kwinqanaba elithile, ukunciphisa umthamo wemitha ye-UV ebetha ngokuthe ngqo emehlweni.
3. Sebenzisa iparasol
Kwiindawo ezinemibonakaliso eyomeleleyo efana neelwandle kunye namachibi okuqubha, ukusebenzisa iparasol kunokunciphisa ngokufanelekileyo ukukhanya kwe-UV kwimekobume.
Nangona ilanga lasehlotyeni lilungile, kubalulekile ngokulinganayo ukukhusela amehlo ethu. Ngala manyathelo angasentla, sinokunciphisa ngempumelelo umonakalo wemitha ye-UV emehlweni kwaye sonwabele ixesha lasehlotyeni elinempilo neliqaqambileyo.
