Ilensi yeTint
Onke amehlo afuna ukukhuselwa kwimitha evuthayo yelanga.Eyona mitha iyingozi kakhulu ibizwa ngokuba yi-ultra violet (UV) kwaye yahlulwe yangamacandelo amathathu.Obona bude bufutshane, i-UVC ifunxeka kwiatmosfera kwaye ingaze ifike kumphezulu womhlaba.Uluhlu oluphakathi (290-315nm), imitha ye-UVB yamandla aphezulu itshisa ulusu lwakho kwaye ifunxwa yi-cornea yakho, ifestile ecacileyo ephambi kwamehlo akho.Owona mmandla mde (315-380nm) obizwa imitha ye-UVA, dlulela ngaphakathi kwiliso lakho.Oku kubonakaliswa kuye kwadibaniswa nokwakhiwa kwe-cataract njengoko oku kukhanya kuthatyathwa yi-crystalline lens.Wakuba ukhutshiwe unwebu iretina ebuthathaka kakhulu iba sesichengeni kule mitha yomonakalo. Ngoko ke kufuneka ilensi yelanga ukukhusela amehlo ethu.
Uphando lubonisa ukuba ukuvezwa kwexesha elide, okungakhuselekanga kwimitha ye-UVA kunye ne-UVB kunokuba negalelo ekukhuleni kwamehlo amakhulu.
iimeko ezifana ne-cataract kunye ne-macular degeneration.I-lens yelanga inceda ukuthintela ukukhanya kwelanga malunga namehlo okunokukhokelela kumhlaza wolusu, ukukrala kunye nemibimbi.Iilensi zelanga zikwangqiniwe ukuba ukhuseleko olubonakalayo lokuqhuba kwaye lubonelela ngeyona nto ingcono iyonke
impilo entle kunye nokhuseleko lwe-UV lwamehlo akho ngaphandle.
