Have you ever wondered about the effect of 3D movies on your vision? What do the professionals have to say about the subject? Keep reading to learn more.
HOW DO 3D MOVIES WORK?
In most cases, 3D movies, TV shows, and other content are optical illusions. Two things are played at the same time and the 3D glasses help your eyes and brain filter the content and interpret it. Your left eye sees one version of the film, your right eye sees another and the combined images create an illusion of 3 dimensions.
WHAT ARE THE SIDE EFFECTS OF WATCHING 3D MOVIES?
3D movies aren’t for everyone. Some people enjoy them with no complains, while others complain of nausea and headaches. According to Luke Arundel, Optometry Australia’s senior resident optometrist, “For young children the glasses require the brain to work hard to process the images. During a long movie, this can create tiredness and discomfort.” Arundel also said, “Adults that are required to wear 3D glasses on top of their prescription glasses may also find the extra layer a little uncomfortable, but the glasses themselves won't damage the eyes or impair your vision." In most cases 3D movies won’t cause any lasting problems, but they may cause discomfort for some.
AT WHAT AGE CAN CHILDREN SAFELY WATCH 3D MOVIES?
The American Optometric Association has created a list of frequently asked questions to address concerns about viewing 3D content. In this list, they point out that most children have developed binocular vision by age 3 and can safely and comfortably enjoy 3D content.
WHAT SHOULD I DO TO PROTECT MY VISION?
The best thing you can do to protect your vision while viewing 3D content is the same thing you should do when viewing 2D content—view it in moderation. The American Optometric Association says that parents can use the same time limits that are set for 2D content. They do point out that handheld devices (whether 2D or 3D) can cause more eyestrain, so time limits should be shorter for children using these devices, and they should be encouraged to take regular breaks. If you stay informed and use caution, you and your family can safely enjoy 3D content together. If you want to learn more, optometrists in Dallas, Detroit, or a city near you, can help you protect your vision and answer your questions.
