Background:3D技术在电影和电视中的使用越来越普遍。时尚设计师们也没有放过这个赚钱的大好机会，开始设计多种可以作为时尚饰品的3D眼镜。

Some think it's the next must-have accessory for movie-buffs. At the cinema why wear those free plastic specs that someone else has used already, when you can buy your own 3D glasses? Designers like Oakley and Calvin Klein hope consumers will pay up to US$180 a pair to be trendsetters.

It's the next step in the personalisation of 3D entertainment. It's already a growing format for movies including the blockbuster Avatar.

Now electronics companies are offering 3D TV sets for the home. But they may supply 3D glasses that work only with their products, not in cinemas. Which would make those stylish designer glasses of limited use.

Just as with the advent of home video recording when VHS battled and triumphed over Betamax, there could be a format war looming over 3D glasses.

Designers hope they're tapping into a fashion-conscious market but soon will those personalised 3D specs be useful or just stylish?
