Moviegoers every holiday movie season flock to theaters to see the latest superhero movie, rom-com, or action blockbuster. Hollywood’s latest craze is the expansion of 3D movies aimed at immersing viewers even more with the characters as they leap off the screens at us.
But have you ever wondered how 3D movies work and if they are bad for our eyes?
Quite simply, 3D films seek to imitate how we see things every single day — in three dimensions. In order to create that effect, filmmakers capture their images with two different cameras set 2-3 inches apart and similar to how our own eyes work.
Modern 3D glasses are an attempt to fuse those two images together into a single image.
The glasses are performing the job our brain does when it fuses the separate images from each of our eyes into one single image. Today’s 3D glasses are polarized lenses and are a drastic improvement over the antique red and blue glasses.
Some people struggle with 3D movies though. The most common issue is people who do not have good binocular vision, or where the two eyes work properly together. Roughly 30 percent of all people struggle with poor binocular vision.
Individuals whose eyes do not work in complete coordination with each other therefore won’t get the proper 3D effects when watching these movies and may instead suffer from headaches, dizziness, or nausea while watching them.
