Iilensi ze-HMC Optical ezinemibala ezi-1.56
Iilensi ze-Photochromic, ezaziwa ngokuba “ziilensi ezibona ukukhanya”. Ngokomgaqo we-reversible interconversion interconversion, ilensi inokuba mnyama ngokukhawuleza phantsi kokukhanya kunye nemisebe ye-ultraviolet, ivale ukukhanya okunamandla kwaye ifunxe imisebe ye-ultraviolet, kwaye ifunxe ukukhanya okubonakalayo ngokungathathi cala; xa ibuyela kwindawo emnyama, inokubuyisela ngokukhawuleza imeko engenambala necacileyo, iqinisekise ukuba ilensi iyasasazeka. Ke ngoko, iilensi ze-photochromic zifanelekile ukusetyenziswa ngaphakathi nangaphandle ukuthintela umonakalo emehlweni ngenxa yelanga, ukukhanya kwe-ultraviolet kunye ne-glare.

Iilensi ze-Optical ze-1.56 FSV Photo Gray HMC
Iilensi ze-Photochromic azilungisi nje kuphela umbono, kodwa zikwamelana nomonakalo omkhulu emehlweni ngenxa yemitha ye-UV. Izifo ezininzi zamehlo, ezifana nokuwohloka kwe-macular okunxulumene nobudala, i-pterygium, i-senile cataract kunye nezinye izifo zamehlo zinxulumene ngokuthe ngqo nemitha ye-ultraviolet, ngoko ke iilensi ze-photochromic zinokukhusela amehlo ukuya kwinqanaba elithile.
Iilensi ze-photochromic zinokulungisa ukuhanjiswa kokukhanya ngokutshintsha kombala welensi, ukuze iliso lomntu likwazi ukuziqhelanisa notshintsho lokukhanya okukufutshane, ukunciphisa ukudinwa kokubona nokukhusela amehlo.
