Sorry, but these aren't great. I wouldn't even say they're good.
I got the "Groove Adv" and they make everything yellow -- less harsh, pretty nice. The marginal magnification is alright.
But I have a multiple-display setup. Hell, even with one widescreen display, it's still a problem. Why? The peripheral distortion. Everything is bent, and worse, in some areas of my vision (i.e. when I look to the corners of the screen), the distortion is so asymmetrical that everything in my visual cortex goes bananas and my eyes get cranky and confused.
Interesting concept, very much needed, good execution in terms of lens tint and marketing, but bad engineering/design and marginal quality.
And frankly, with the end product being mass-manufactured out of plastic in China, I expect the retail price of $99 or a super-discount price of $40 to still get me something more than a worse headache than without the glasses. Incredibly sad that this turned out to be junk.
