How do 3D glasses work?

Remember the first time you’ve watched a 3D video or the first time you’ve watched a stunning IMAX 3D movie at the cinema and wondered about the whole incredible immersive experience? Have your parents and grandparents ever told you about their first experience with conventional cinema? My grandma told me that when she first saw a movie at a cinema and saw a train entering a station and moving in her direction, she got really scared because she thought it was going to run her over. And that wasn’t even 3D, it was the sheer power of cinema. 3D is much more than that and you can’t help wonder how do those cheap plastic 3D glasses you’re given at the cinema really bring you the 3rd dimension?

How do 3D glasses work? 

3D glasses work by helping your eyes filter chromatically opposite colors into one single image. 3D glasses have different-colored lenses. Usually one is red and the other is cyan. This makes one eye see all the red in a picture and the other lets you filter all the cyan and then your brain does the whole magic and overlaps the two of them into a 3D picture. These are the basics of the Anaglyph glasses. However, there another two types of 3D glasses out there. Enter polarized and shutter 3D glasses!

The polarized 3D glasses also work by deceiving our eyes. They have yellowish-brown hue and would allow each of your eyes to see one of the two individual images on the screen and then your brain would do the rest and help you enjoy the amazing IMAX 3D experience. Yes, these 3D polarized glasses are used with IMAX.

The shutter glasses can be considered the future of 3D glasses. They use something called “active 3D” technology; the previous two used passive 3D. So, what’s the difference? The difference is they don’t deal in different colors or filtered images to create that depth effect. They have LCD screen technology that alternatively darkens each lens so fast that you don’t notice it, but you can enjoy the whole 3D experience. They’re much more expensive and I don’t think they’ll appeal to the public. The overall 3D image quality is better, but still, the other cheaper, plastic 3D glasses still do their job very well to be replaced by something fancier.

Everyone loves to have a large-sized TV in their homes, but properly accommodating the same can be a real issue sometimes, I was able to resolved my problem by using a corner tv mount to save space.

When did the first 3d movie come out?

The first 3d movie was “The Power of Love” and it came out in 1922. Yep, 3D movies are not a thing of the last 40-50 years. They have been part of our lives for nearly 100 years. Nevertheless, 3D technology really became mainstream with the premiere of James Cameron’s Avatar film. Somehow, everybody wanted to watch 3D movies all of a sudden after they had watched those blue creatures riding around on wild fantastical animals and that love story unfolds right in front of their eyes.

Now, it’s probably normal for you to go to the cinema and watch a 3D movie. Actually, watching a 2D movie might be a little bit odd, but with the ever-evolving VR and AR technology of our days, who knows what the future might have in store for the entertainment industry?
