Ihlobo lizisa iintsuku ezinde kunye nokukhanya kwelanga okunamandla.Kule mihla, uza kubona abantu abaninzi
ukunxiba iilensi ze-photochromic, ezitshintsha umbala wazo ngokusekelwe ekukhanyeni.
Ezi lensi zithandwa kakhulu kwimarike yezibuko zamehlo, ingakumbi ehlotyeni,ngenxa yamandla abo
ukutshintsha umbala nokukhusela kwimitha yelanga. Abantu abaninzi bayaqaphela
umonakalo onokwenziwa yimitha ye-UV, kungekuphela nje kulusu kodwa nakumehlo ethu.
Ngelixa Umonakalo we-UVemehlweni kusenokungabi yingozi njengokutsha lilanga, ukuchatshazelwa lilanga ixesha elide kunokukhokelela kwiingxaki ezinkulu zamehlo, ezinje nge-cataracts kunye ne-macular degeneration.
ETshayina,kusekho ukungavisisani malunga nokuba kufuneka unxibe niniiiglasi zelanga.Nangona kukho ukukhanya okunamandla ngaphandle, abaninzi bakhetha ukunganxibiizihlangu zamehlo ezikhuselayo.
Iilensi ze-Photochromic,Ezilungisa umbono kwaye zikhusela ekukhanyeni ngaphandle kokutshintsha iiglasi, ziba lukhetho oluthandwayo.
Iilensi ze-photochromic ziba mnyama ekukhanyeni okuqaqambileyo (njengangaphandle) kwaye zikhanye ngaphakathi. Olu tshintsho lubangelwa yinto ebizwa ngokuba yi-silver halide kwiilensi,
esabela ekukhanyeni, itshintsha umbala welensi ngokusekelwe kubukhali bokukhanya kunye nobushushu. Ngoko ke, iilensi ziba mnyama xa ilanga likhanya kakhulu kwaye zikhanya
ekukhanyeni okuphantsi okanye kumaqondo obushushu aphantsi.
Nantsi ingqwalasela emfutshane yemibuzo eqhelekileyo malungaIilensi ze-photochromic:
1. Ingaba banika umbono ocacileyo?
Ewe, phezuluIilensi ze-photochromic ezisemgangathweni zicacile ngaphakathi kwaye azinciphisi ukubonakala.
2.Kutheni iilensi zisenokungatshintshi umbala?
Ukuba azifiphali ngenxa yelanga, izinto ezibonakala lula ekukhanyeni ezikwiilensi zisenokonakala.
3.Ingaba ziyaguga?
Njengazo zonke iilensi, zinobomi obude, kodwa ngononophelo olufanelekileyo, kufuneka zihlale iminyaka emi-2-3.
4. Kutheni zibonakala zimnyama ngokuhamba kwexesha?
Ukuba azigcinwanga, iilensi zisenokungaphindi zikhanye ngokupheleleyo, ingakumbi ukuba zikumgangatho ophantsi. Iilensi ezikumgangatho ophezulu akufanele zibe nale ngxaki.
5.Kutheni iilensi ezingwevu ziqhelekile?
Zinciphisa ukukhanya ngaphandle kokutshintsha imibala, zibonelela ngembonakalo yendalo, kwaye zilungele wonke umntu, nto leyo ezenza zibe lukhetho oluthandwayo.
