The Pain of Watching 3D Movies With a Lazy Eye


For some people, Hollywood’s 3D movies may induce more dizziness and nausea than thrills. That’s because for children watching 3D movies with a lazy eye, or amblyopia, it’s nearly impossible to enjoy the effects like their friends.

Vision Problems Coming to an Amusement Park Near You


The 3D craze on the big screen is spreading to new ground - or should we say, grounds.  Universal Studios Hollywood announces a new, 3D theme park attraction
“Transformers the Ride 3-D.” While this will be great fun for most theme park goers, it will be frustrating to people with vision problems for a number of different reasons.

1.  If you have binocular vision problems, you’ll miss out on the 3D effects.  Binocular vision problems occur when the brain can’t effectively combine the images it receives from the left and right eye into a 3D image.  It affects a person’s depth perception.

To understand this concept, take a look at this great video on how 3D films work.  Today’s 3D films use a technique cause polarised light to produce the image, which glasses are designed to pick up.  This is a great video on how it works.



Note that when the woman in the video tilts the polarizing filter, she suddenly comes into view.  For a person with binocular vision problems, the 3D glasses won’t achieve the same effect because the person’s eyes don’t work together to combine the images.  

2.  If you have binocular vision problems, you probably don’t know it.  According to the American Optometric Association, one in four children has a vision problem that affects their ability to learn.  This can include binocular vision problems.

Because these types of vision problems tend to evade traditional vision screenings, you may not even realize you have an issue with your visual system.  Keep in mind that you can have a vision problem even if your vision is 20/20.

3.  If you have a vision problem, you’d be better off going on a real amusement park ride.  We recently blogged about the value of children getting outside during the summertime and looking at objects at all different distances.  This can help strengthen your visual system.  

If you were on one of those old fashion rollercoasters, you’d have the chance to look at distances near and far.  For a person with a vision problem, this would be helpful when used in conjunction with treatment like vision therapy.

If you attend a 3D movie or amusement park ride and don’t notice the 3D effects, you should get a Functional Vision Test to determine if you have a vision problem.

Does a Vision Problem Prevent Your Child from Seeing in 3D?

Could 3D movies and games help us spot vision problems?

A recent video released by the American Optometric Association indicates that 3D games and videos might help us spot vision problems that "if left undetected, might result in learning difficulties."
