It depends what fits you. I suggest trying the dye and if you like it then buy it. I personnally can't wear the proteus as they dig into my head and I have heard the invision has some problems too. I'd just get a pair of Ize much better
Never had a problem with cracked lenses, but I do get stinking headaches after wearing my Proteus for too long..... It seems to dig into my temple.....
If you wear glasses, you don't want an Invision, they don't go too well with glasses apparently.
I heard the Invision was made for the smaller headed person. If you have a long face your Nugget will stick out of the top and if you have a basketball head it will squeze your temples causing head aches. I like my IZE but I need a black one now!
