In real life, they work like 3D glasses, but there are halos. Some images and videos work much better than others. Some of the videos appear to have been created in an attempt to make the image appear closer to your monitor and then difficult to see. So if this is awful for you, try a few different videos before you give up. There are color bar test pages that you can use to test glasses for leaks. In these tests, the right "blue" side perfectly obscures the left "red" image. The Red" However, the lens allows some of the green to enter the left eye. Since most videos are actually red-cyan (not red-blue), green should only be visible in the right "cyan" eye. This leakage of dark green into the left eye causes halos. Bottom line, red seems like the wrong shade. Image aside, the goggles are quite comfortable and offer full coverage, so peripheral ambient light doesn't interfere with vision. I think they will work fine if you have a red/blue 3D image instead of a red/cyan image, although this cannot reproduce full color. Also YouTube 3D does not support red-blue. Supported multicolor glasses are: Red/Cyan, Green/Magenta, Blue/Yellow. Product Purchased: Pro-Ana(TM) PROFESSIONAL 3D Red/Cyan 3D Movie Glasses Distribution: Peep Partners I haven't tried them yet, but I think next time I can try Trioscopic ("pure green" / "pure magenta"). If it works better I'll still wear these glasses when I can't use green/magenta. But first I need to find out if Green/Magenta is compatible with something other than YouTube. ---Update---After a few more uses (adult use only, no abnormal use) the goggle frame broke into plastic above the blue lens on the side of the nose. The plastic used in the frame appears to be very brittle. I was able to glue it back together, but breaking it so easily/quickly loses another star.
