I just recently got back from watching The Dark Knight Rises with captions. In this case, it didn't use open captioning or rear window captioning (RWC). The theatre used the Sony subtitle/caption glasses. They do take a little getting used to at first. No captions will show until the beginning of the movie.
They've got their good points and their bad points. But basically, the glasses have room for improvement.
- Subtitles are easily readable with green letters
- Tapping Menu on the battery pack with + and - adjusts the captioning mode and brightness
- Subtitles show up no matter where you look
- After wearing them, they'll feel a bit heavy and the bridge of your nose may hurt
(in my case, it was painful due to the noserests pinching me, but didn't hurt til I took them off)
- Might cause some eye strain with some people due to the focal plane of the subtitles. Meaning, you're going to be reading subtitles close to you, then look at the movie screen.
The suggested improvements:
- the ear pieces could be made adjustable, like longer or shorter
- the eyepiece connector or middle of glasses could be made hinged to allow for those with one good eye to see more of the subtitles
- the subtitle placement could be made adjustable
- if not hinged, maybe use wraparound glasses?
- the nose rests could be made adjustable
- possible to make "clip-ons" to display subtitles on the person's own glasses?
Came across these pages/blogs mentioning it as well:

And interestingly enough, a Quick Start Guide for the glasses. There's more like this with a little more looking around.
