Invisible 3D Glasses

Browsing around the online Hindu newspaper, I saw an article - "Students explore career avenues". Of late, career choices especially by students and the thought processes behind it has been very much on my mind... So I decided to take a closer look at this article... It was a fairly mundane article about a panel discussion on 'Career Opportunities for Higher Education' at Periyar Science and Technology Centre campus in Chennai... But what caught my eye was this picture that went with the article and more important, the caption under the picture ("Students try out 3D glasses at one of the stalls at Chennai Science Festival on Monday.

I see ONLY one person in that picture wearing glasses... and that (to my untrained eye) does not look like 3D glasses! Maybe proofreading and newspaper editing are potential career choices!
