Sunglasse

Hey!
I just started some airbrushing,and i really like it!...i find it does a awesome job!!!...i know this has nothing to do with tinting,but i wanted to change the color of my lenses.Iwant to put them like a blue...or metallic blue.i was just wondering is it possible to change the color of the lense,or should i tint the lenses,??
If i tint the lenses,what should i do and use/???

well...Plz write back as soon as possible!
thanx a million!
Jay

P.S:If you don't know what to say or can't help me,can you please tell me someone who can???...thanx!!!

i am alomost positive a good eyeglass shop can do that for you, it would be difficult to do with window film though.

alright !..thanx a lot!...i appreciate it!
