BIAL Red-blue 3D Glasses/Cyan Anaglyph Simple style 3D Glasses 3D movie game-Extra Upgrade Style

Yes, plastic, but precisely-made with no distortion in the lenses. The frame-fit is tight going on to my normal adult-sized head, but once in place the frame assumes a perfect secure fit. The front of the frame fits over my mid-sized prescription eyeglasses like it was designed for them. No unwanted contacts or increased pressure.I purchased these for use with one of the 3D modes of Gaia Sky. Works perfectly for that.

Love these! They are nice and sturdy. They fit over top of my prescription glasses very nicely. So I can still see while I watch the movie. Nice!

I was really hoping for a next-level optic-quality anaglyph experience, but these glasses are almost identical to some old NVIDIA-branded ones I had sitting around. they're pretty good, as far as plastic lenses go--I've definitely seen worse--but I was looking for something more. Comfort-wise, they're fine, and they worked great with some anaglyph blu-rays I have. The case is a really nice addition; it's one of those expanded-foam affairs with a quality fabric covering and a good zipper closure.

good durable sunglasses, fits over most glasses.

You cannot argue with the price. And the glasses do exactly what they claim. There is no need for glass batteries or even a 3d tv / monitor (just use VLC and change video settings; takes about 2 seconds once you know where to find the 3d option). So what is the downside? Afterall, you are saving hundreds of dollars (more like a thousand dollars or more) so what gives?Well, many movie scenes will look "washed out". Once you remove the red & green colors from the movie, everything will tend to a look greyish. Is this a major issue? For the price? No, absolutely not. But since most 3d movies are a visual spectacle (Shakespeare they ain't) you may find it annoying to watch your favorite movies without the full color spectrum. To be clear, your movies will not be full on black & white, but in all likelihood you will notice the difference to a regular movie.Other than that limitation, I was pleasantly surprised and can heartily recommend these glasses to 3d enthusiasts.p.s. if you are new 3d (or you are familiar with pre-Avatar 3d), don't expect objects to come out of the screen at you. 3d these days more generally refers to your display/tv/monitor looking like you could reach into the display. I am a huge fan, but it is an acquired taste. For many people, they don't enjoy this type of 3d but for the price of these (refundable, I think?) glasses there is an easy way to take it for a test run and see if it works for you.

You can see from the photos I attached the blue lens is working perfectly, but the red lens isn't right.I tired 3 different screens including my phone.I thought mine is defective, but after I checked other reviews, they had the same problem!

Product as described, fast delivery. 👍🏼

I regularly go to the APOD (Astronomy Picture of the Day) website. Occasionally, they publish a red/blue "3D" picture of something. Without the right glasses, the pictures are... well... kind of ugly.Dislike: Nothing.Like: I need glasses. This product fits over my glasses. It came with a nice case. The case also held a microfiber lens cloth. All good.The Integrity helicopter in 3D on the surface of Mars is fun to see. Lava falls on Mars are spectacular. A boulder field on Mars is almost familiar. The surface of Pluto is exotic. Some pictures of the surface of comets and asteroids are (wait for it) out of this world. In terms of my values, the glasses paid for themselves within minutes of being received.
