I want to see Godzilla. They are offering it in regular format or 3D. What do I need to see the movie in 3D. Does the theater offer glasses or do you have to bring your own. I haven't a clue how this works. Thanks for any light you could shed on this.

Theaters show their 3D movies in what is called "Passive 3D", thus all one needs is cheap plastic glasses. The down side of Passive 3D is it cannot produce video at 1080p resolution, thus some detail is lost.

TV sets that are 3D some use Passive Glasses, which are much cheaper to buy, but there again you do not get the ultimate in picture resolution. We have a 60" Mitsubishi 3D tv set and it uses "Active Shutter Glasses". These will reproduce the full 1080p resolution in the 3D content one is watching.

Most probably won't notice the difference in resolution, but anyone that is used to watching 1080p via Blu-ray DVD's or the limited TV content, can easily see the degradation going from 1080p to 1080i/720p resolution.

I think today's 3D is great and it will only get better as technology improves. The prices have already come down immensely on home theater 3D TV sets. Any set that can reproduce 3D also reproduces all other resolutions much better than a non-3D set. There again, one has to have watched both High Definition resolutions a lot to be able to distinguish one from the other.

All you need for the theater is the money for the tickets/popcorn/pop and candy, so take along at least $100 if you are going alone. With 2-3 others you are paying for? Ouch!

Being sighted in only one eye- I don't see life in 3D and I never have to pay to see movies that way..So I find it interesting to know that without the glasses, the movie looks "blurred" - I HAVE seen those glasses, and they look, to me like one lens is red and the other blue (or green?) (evidently that is the side I don't see out of, since I can only recall seeing"red" after putting them on0

What is the mechanism that makes having two different colored lenses make you be able to see in 3d?

As I understand it, (and maybe someone with more technical knowledge than myself can answer better), the reason the lenses on the glasses are two different colors, is because our pupils will be at different dilation.

Meaning, the pupil that has the red lens over it, will dilate larger (or is it smaller?) than the other pupil.

I wondered if movie theaters clean and reissue glasses, or trash them (ie send then for recycling into other items).

This article says it depends on the theater, some use dishwasher type machines, others have staff hand-clean the glasses, others give patrons disinfecting wipes to do it themselves (ewww):

Ok, very interesting! Thanks!
