3D glasses: A brief guide. Watching movies or videos in 3D means that you, the viewer, are seeing images across three dimensions — that is, if you're wearing 3D glasses. Specialty glasses give 3D movies an appearance of height, width and depth (three dimensions) for a more immersive viewing experience.

Why do you need glasses for 3D movies?

Moviegoers wear special glasses where one eye sees waves of light traveling along one meridian and the other eye sees waves of light traveling along another meridian 90 degrees away or perpendicular to the other eye. 3D movies shown in theaters and theme parks utilize polarization.

What happens if you watch a 3D movie without the glasses?

If you look at a 3D image with your naked eyes (no glasses) you'll notice the picture has 2 layers, one is red and one that is blue, but it is never perfectly aligned with the red part, it's always off centred. This is on purpose.

Do 3D movies still require 3D glasses?

Full rim passive polarized or active shutter glasses are the specialized eyewear required to enjoy a movie in 3D. If you take off your 3D glasses during the film, you'll see a pair of slightly overlapping images that are a little out of focus.

What is so special about 3D glasses?

The 3-D glasses have polarizing filters matching to the projectors' filters. Your brain merges the images to see depth. But tilting your head puts the filter at the wrong angle — each eye may start seeing a weak version of the other's image. Circular polarization avoids this problem.

Is it OK to wear 3D glasses all the time?

There's no evidence that viewing too much time wearing 3D glasses causes any long-term eye problems, but it may be uncomfortable in the short-term. The solution for most children and adults with vision issues is to view 3D content sparingly, take frequent breaks, and sit farther away from the screen.

Do 3D glasses actually work?

These glasses utilize special red / cyan lenses to interpret the image. These lenses produce the images you see by color filtering the layered image that you're actually looking at. While one lens filters out all the red in an image, the other lense filters out the cyan, causing your brain to see the picture in 3D.

Can you watch 3D movies with regular glasses?

Watching 3D movies is possible even if you have to wear eyeglasses. Go ahead; enjoy the latest 3D movie at your nearest theatre.

Do we have to return 3D glasses after movie?

Generally, Active 3D glasses are a loan. They're open and on a tray which they hand you at ticket check. They're collected, sterilized, and reused at the end of the movie.

Is it possible to watch 3D movies on a normal TV?

You need a 3D TV or video projector, a 3D-enabled Blu-ray Disc player, and some 3D-compatible Blu-ray discs. If you want to watch 3D content via HD cable or satellite, you need a 3D-compatible box and a subscription to 3D channels. You need to wear glasses to watch 3D. However, these aren't the cheap paper glasses.

What if I watch a 3D movie without glasses?

The two parts of a 3D signal that reach your eyes require the use of either Active Shutter or Passive Polarized Glasses to see the result. When such images are viewed without 3D glasses, you see two overlapping images that look slightly out of focus.

Does 3D movie make you dizzy?

Nausea and/or dizziness

Seeing 3D movies can increase rating of symptoms of nausea, oculomotor and disorientation, especially in women with susceptible visual-vestibular system.

Does real 3D need glasses?

RealD 3D and Imax Digital 3D both utilize passive 3D technology which makes use of relatively lightweight eyewear. These passive 3D glasses use polarizing filters to allow each eye to see a slightly different image. HDTVs like LG's latest Cinema 3D TVs work in a similar fashion.

Do I need special glasses to watch 3D TV?

You have to wear special glasses to watch 3D on a TV.

How do people with glasses watch 3D movies?

For many people who wear glasses, bigger truly is better. Forget about those cheap plastic glasses the theater provides you. For hardcore movie buffs who wear glasses, there's only one way to go: your own prescription 3D glasses.

People who are unable to use both eyes together to achieve binocularity will not see the depth of 3D content.

Why were 3D glasses red and blue?

The viewer would then use colored glasses with red (for the left eye) and blue or green (right eye). The left eye would see the blue image which would appear black, whilst it would not see the red; similarly the right eye would see the red image, this registering as black. Thus a three dimensional image would result.

What was the first 3D movie with glasses?

It has to let something through, otherwise the glasses would be blank! So half the UV light is still getting through your 3D glasses and this is well enough to cause long term damage that can be prevented by proper sunglasses designed to filter UV.
