How old are children to watch 3D movies?

Yes, at least for children's eyes, there is no problem. There is no evidence that watching 3D images will damage children's eyesight. In fact, there is not much difference between looking at 3D images and looking at real objects. This is why the American Academy of Ophthalmology believes that watching 3D images is unlikely to harm children's eyes.

When you look at things at ordinary times, the image your baby gets from each eye is a little different. The brain uses these images to construct a three-dimensional concept about the world. When watching a 3D movie, special glasses can make the baby's left eye and right eye get different images, thus producing a three-dimensional effect. When playing 3D video games, the position of the image on the screen works together with the position of the baby's head, so that each eye can receive different images.

Some video game designers and 3D equipment manufacturers may remind you not to let children under the age of 6 use their products, because they may harm the baby's developing eyesight. However, there is no conclusive evidence and no convincing theory to prove that this kind of worry is really necessary.

Contrary to the above suggestions, most of the baby's eyes are fully developed at the age of 3. Before that, your children are unlikely to watch 3D movies or play 3D video games often. In any case, 3D images are very similar to what children see in real life from birth to 3 years old.

On the other hand, eye fatigue and nausea caused by exercise dizziness may be a problem, especially when your child is old enough to watch movies in the cinema.

Constantly changing, the images seen by two eyes have exaggerated differences, dim lights, images that come at you quickly, and changes in focus may be a bit difficult for some viewers to adapt to. If your baby feels uncomfortable, tell him to close his eyes for a few minutes, or try to sit closer or farther from the screen. Some people feel eye fatigue and dizziness more easily than others. If your child's eyes are inconsistent, such as squint, he is more likely to feel tired, headache or nausea when watching 3D movies.
