Headaches Resolved!

In the last two posts I have both highlighted some recent Estonian Research and consulted international experts on the matter. (Please refer to the last two posts for background.) 

Now it's my turn to weigh in: so, what are we to make of this Estonian study? I would suggest three big takeaways:

1. 3D cinema may be the stimulus, but it is not the etiology (cause).
2. Anyone with difficulties viewing 3D cinema (such as headaches) has just received an informal vision test. It’s a lesson the industry still has not learned in its push for “the next big thing.” 
3. What may be true about watching 3D cinema will also be true about content viewed with stereoscopic virtual reality headgear. (This helps explain why more than 20% of my undergrad students at the university experience headaches, dizziness, or nausea when viewing virtual reality content.)
