I tried this item (ProAna) and a pair of ProX goggles for comparison. -ProAna (this item): Pro Ana(TM) 3D glasses for movies - HIGH END - Anaglyph glasses for computers, movies - Less ghosting - Ships from USA - ProX: Pro X style red/cyan 3D glasses for movies and games on flat screens - ProAna (this article) works much better. The frames seem very thin, but the main thing is the glasses. The lenses are correctly colored so that even bright light is eliminated when looking through both lenses (meaning the red and blue colors are correctly toned to avoid ghosting). They definitely work, you get a strong 3D effect but you still don't see colors well, at least if you use Nvidia Discover for gaming. Sometimes I feel sick playing games with them, but that goes for all red/cyan 3D glasses. Overall I am very happy with the purchase. EDIT: After using them for a bit I can say that while the colors of the lenses match perfectly, the color doesn't match most things. Strangely, the blue lens is good, but the red lens has noticeable halos and that makes things weird. I'm curious as to why this is happening as the lenses are absolutely perfectly matched and the blue is good, the red should be too, but the red lens definitely still has halos. I really don't know why anaglyph colors should be adjusted. never an option. The Nvidia colors are pretty weird and the YouTube red doesn't go well with these glasses. I think both NVIDIA and YouTube should have a simple Flash or Java color matching process to accommodate differences in 3D glasses. It certainly won't be difficult! In general, I think you should rely on your luck. But they are very cheap so I can't complain too much.
