3-D Glasses are a drag
Watching a clip of Monsters vs. Aliens or Avatar on a 3-D TV can be fun. But first you have to need to put on a pair of compatible glasses — either specially polarized ones, or active shutter glasses that contain electronics synchronized with the images on the screen to deliver a 3-D effect to your eyes.
Wearing glasses for a three-hour movie like Avatar is one thing. But doing it every day, day after day, can quickly become annoying.
Though active shutter or polarized 3-D glasses are getting more lightweight and sleeker, there’s no escaping that they are still a pair of glasses you’ll have to wear every time you want to watch 3-D video on your TV.
What’s also not clear is how 3-D glasses will work for those who already wear prescription eyeglasses. For now, you just have to put them on over your regular glasses — hardly an elegant solution.
The glasses will also cost extra. Consumers who spend $3,000 for a 3-D TV will have to shell out more to get a pair of glasses. Active shutter glasses can cost $50 a pop or more and for a big family, the cost can add up. Also, buyers need to factor in losses, because glasses can be misplaced easily.
TV makers will likely offer bundled deals where a pair or two of glasses are included with purchase of a TV set, but so far there have been no clear announcements.
And if you’re having friends over to watch a movie or a game, you’ll have to remind them to bring their own glasses. If they forget, they are out of luck.
Some companies, such as LG, Samsung and Mitsubishi, are showing prototypes of 3-D TVs that require no glasses. But in that case, the TV can be a very limiting experience. 3-D TVs without glasses have a very specific viewing range — four feet in some cases — and have very specific viewing angles, so they’re not well-suited to screenings with more than a small number of viewers
