The day has finally come and technology has once again taken a massive leap forward with the creation of 2D glasses. Yep, that’s right, 2D not 3D. Some people get headaches when watching 3D movies and others just flat out hate 3D. The simple solution would be to just not buy the more expensive 3D ticket and 2D glasses, but there are some people who get dragged to 3D movies by their friends or whoever, and I can somewhat understand how these glasses could be helpful for those that get headaches from 3D.

2D glasses allow any RealD 3D movie to be viewed as if it is a normal two-dimensional movie and can be purchased for $7.99 plus $2.00 shipping here. Here’s how they work:

When you watch a 3D movie, there are actually two images being projected onto the screen. That’s why the screen is blurry when you look at it without glasses. In 3D glasses one of the lenses blocks one image and the other lens blocks the other image.

Thus, when you watch a 3D movie each of your eyes is seeing a slightly different image. Your brain combines those images together, creating the illusion of a 3D image.

2D Glasses block the same image with both lenses, so each eye gets the same picture resulting in a 2D image and an elimination of eyeball strain.
