The ones that work best are called Pro-Ana. You can get the paper versions or $1. These ones still work fine, they are just not durable.

The BIAL glasses are also very good and easier to get on Amazon, for $10; https://www.amazon.com/BIAL-Red-Blue-Glasses-Anaglyph-Game-Extra/dp/B01ANJXCU2/
@xyz said: Looking fabulous. Thanks a bunch. I'm really happy with how it turned out.
Also, I have a bunch of brand new 3D glasses. If you (or anyone else) wants a pair, just private message me and I can send over for free. Cheers.
Here are some 3D shots of Decay. As before, you need red/cyan 3D glasses to see the effect.
Godot Stereo 3D has been accepted on the Godot Asset Library. Feels great to see my work in the editor.
I've published this add-on on Itch.io, you can download on my profile.
Because I want everyone to be able to see their game and Godot in stereo 3D, I will be giving away free 3D glasses. These are Pro-Ana red/cyan anaglyph 3D glasses, the best quality on the market. Just send me a PM with your mailing address and I will send you 2 pairs of glasses for free. I can ship anywhere in the world.
I've updated the shader. It looks much better now. Will post the code soon.
Update 2.0 is on Github.
Stereo is wonderful. 
️ Unfortunately, it is no longer fully supported. Anaglyph narrows the color range very much. 
This is a new type of anaglyph filter. Still loses a lot of color, but it is much better than older methods.
cybereality Yeah, less color is lost — I checked it right away.
Alright, thanks.
