ARE 3D MOVIES BAD FOR YOUR EYES?

Scores of Hollywood’s latest blockbusters were released in theaters showing both a standard version (2D) and a 3D version. If you’ve ever been to one of the 3D showings, you know that you have to wear special glasses to experience the 3D effect of the movie. When 3D films were gaining popularity, many people were skeptical about the effects a 3D film might have on your vision. Today, some are still concerned.

ISN’T 3D VISION NATURAL?

You may be asking yourself, “How could a 3D film be bad for your eyes? Don’t we see in 3D every day?” It’s true that we see the world around us in three dimensions, but movies can’t achieve the 3D effect without special methods. 3D films need to be shot with two different cameras that have polarising filters designed to create the 3D effect. This effect is viewable only when the viewer wears the glasses designed to filter the polarization and bring the 3D effect to life.

It’s this method of creating 3D images that many suspect causes vision problems.

WHY DO PEOPLE BELIEVE WATCHING 3D MOVIES IS HARMFUL TO YOUR VISION?

The polarization of 3D glasses filters light to each eye differently. This asks the muscles of each of your eyes to work separately, rather than in coordination with one another. Your eye muscles can begin to feel strained, causing headaches, dizziness, and nausea. These effects are usually temporary and can be averted by looking away from the screen for a few seconds.

SO, 3D FILMS ARE BAD FOR YOUR EYES THEN?

Actually, no. The headaches and nausea are basically the result of stress from your eyes and brain having to work differently to process images. As far as your eyesight goes, there is no evidence suggesting that 3D movies cause long-term vision problems.

If you are more sensitive to headaches from 3D films, medical professionals recommend you take more breaks, or don’t watch them frequently. You should also try sitting farther from the screen, so your eyes don’t have to move as much.

3D movies may amplify the symptoms of an already existing condition, especially in children. If your eyestrain is significant and persistent, you might have another vision problem. If you are concerned, schedule an eye exam with your optometrist.
