Of course, the most readily noticeable side effect of stereoblindness is the inability to see 3D movies, games, or pictures. Movies filmed in 3D are usually shot by two cameras, placed at about the same distance apart as human eyes.
The two images are then superimposed on each other, mimicking the process of stereo vision in the brain. If you look at a 3D film, or other form of media, without any additional instruments, the image looks flat and blurry, which is why you need a pair of 3D glasses.
Older 3D films relied on color systems to achieve the 3D effect. One camera would have a blue filter, and the other a red filter, and the audience would receive a pair of 3D glasses with one blue lens and one red lens. The different colors mimic the image disparity of looking at real-world objects, which creates a sense of depth. Modern 3D entertainment relies on polarization, not color.
One lens of the polarized glasses views vertical light waves, while the other views horizontal light waves. Again, the image disparity between the right eye and light eye mimics real vision, making the flat image on the screen appear to have depth. Some doctors recommend surgery, regardless of age, while others find vision therapy helpful. Test your knowledge. What are you wondering?

Jun 1, I play Minecraft which is a game with 3D graphics. I like your videos I posted 2 of my own videos thank you for teaching me and my class mates. Thanks for commenting, emry!
Oct 12, Brandon Ta Oct 1, I hate 3D glasses because I have to put them over my thick glasses. Is there some sort of contact lens 3D glasses?
Oct 4, Kendra w. Jun 25, This is very interesting I love 3D movies. I think you guys should do more wonders about animals though.
Kevin McMurtrie Jun 24, Jun 24, Have fun, lala! Nancy H. But I love regular movies. Tionna Pearson Jun 24, Thank for giving me the imformation. I just love watching 3D movies. Cody Jan 11, Great wonder I love ur website it is the best how do you get all this ideas?
Jan 12, Cole H Jun 24, I knew 3D was some kind of trick they do with your eyes For me, 3D movies make me give headaches, so i have only seen a few. I didn't know a lot about 3D but i did know it looked cool but i learned that detectors use two cameras to mimic the human eye to you can get that 3D effect. Kristopher Feb 12, When I go to a movie that's 3d I do feel like I am in the movie things do pop in your face one time some one was stuck on a island full of dinosaurs and the guy was being chase by a dinosaur that was a t-Rex movies that pop out are super cool.
Wonderopolis Feb 17, Isabella Feb 12, Dear wonderopilis, I love you blog and I love 3d movies. Dear wonderoplis, I love 3D I just thought people were advanced if they made 3D but it's pretty easy I think i will make one when i grow up.
Wonderopolis Feb 12, Gwendalyn Feb 12, Dear wonderopilous, Hello how are you doing? So before i go i have a question how do those 3d glasses work how do they make everything come at you? Makena M. Feb 12, Dear Wonderopolis, I really like this text it is awesome!! Do you have any more about 3-D movies or anything about Wonderopolis? Your friend, Makena M. Taylor Feb 10, Dear Wonderopoils, I love your blog it teaches me so much. Wonderopolis Feb 10, Reed Johnson Nov 17, Wow I never thought that was how 3D works, many thanks Wonderopolis :.
Wonderopolis Nov 17, Gwen H. Oct 14, I love 3D movies! I feel as if I could reach out and grab everything. Do you like 3D movies, wonderopolis? Thank you for writing this wonder!!! Wonderopolis Oct 15, Jordy K. Mar 13, I used to have no depth perception, so I couldn't see 3D when I was little Wonderopolis Mar 13, Derek L.
Oct 24, I still don't get it, I get the glasses part with binocular vision but what about the screen? Is the rest from are mind? Or just the screen? Hey Wonderopolis, I have a question: Why was this wonder ? Hadn't the Wonders gone all the way to a thousand-something??
It shows 'Wonder-of-the-Day' Wonderopolis Oct 20, Wonderopolis Oct 25, I love Wonderopolis, so for my guess I think that it's about I love you guys! Wonderopolis Oct 19, Ella Oct 19, I always wondered about this.
Thanks so much, Wonderopolis! Gregory , Mandy, Blake, Sarah Jun 19, That was a cool wonder. I never knew how you could make 3- D movies and how your eyes and brain work to create the image. It's interesting how the movie makers have figured out a way to copy how our eyes work to create a 3D image.
I learned that 3D stands for three dimensional and that 3D has width, length and depth. Resurrection School. Wonderopolis Jun 19, Wonderopolis Apr 17, We agree, Walker! Thanks for visiting us and sharing your comment! Paige Mar 29, I don't really like 3D but it was cool to see how it worked, thanks. Wonderopolis Mar 29, Dear Wonderopolis, We love your amazing facts and things to learn! Most days our school Walker Elementary goes to your website and look for amazing facts about, well, anything.

Wonderopolis Oct 16, I did not know a lot about 3D, but it is awesome. Wonderopolis May 3, Such a film is generally shot using two perspectives which are not too different from each other. This can either be done using two cameras or a camera with dual lenses set a uniform distance and angle from each other. The two angles can also be computer generated graphics. Since there are two sets of films, special projection hardware is used to display the film.
The film appears as a single image with the help of special glasses. Such hardware is not only available for the 70mm movie screen, but can be used for television broadcasting too.
There are several new technologies which use alternative techniques cut down on costs. It means that using this projection system, the film need not be shot using two lenses. This reduces the cost considerably as the film can be relayed as both a 3-D projection as well as a 2-D projection, because the film is shot as 2-D but projected as 3-D. Stereoscopic photography creates an image known as anaglyph. Although two lenses are used, a single image is created.
