Scientists prove what we all already knew: 3-D gives us headaches

Many of us are irritated by 3-D glasses—after all, they're bulky and annoying—and some swear they cause headaches. Now haters can hate with good reason: Science has quantified just how bad 3-D really is.

The Guardian reports that, according to a California State University study led by L. Mark Carrier, 3-D is three times more likely than 2-D to cause dizziness, eyestrain and headaches. Carrier told the American Psychological Association, "All other things being equal, I would say you're increasing your chances of having some discomfort."

It gets worse. It turns out that in addition to problems with vision, there are few actual benefits to 3-D:

3D movies do not allow viewers to experience more intense emotional reactions, are no more immersive, and do not offer any advantage over their 2D counterparts in terms of enhancing the ability to recall a film's details.

The study makes us curious, because it does not say which 3-D movies were actually viewed. We wonder if subjects got more headaches when watching a movie that was converted into 3-D via post-production process versus being filmed in 3-D. (For example, Avatar was filmed with special 3-D cameras, whereas Transformers: Dark of the Moon was converted.)

But as ScreenRant reports, "3D movies made up less that 4% of the total films released last year but accounted for 11% of all gross receipts." Therefore 3-D is unlikely to flatten out anytime soon.

What do YOU think about 3-D?
