How do 3D Movies Work and Affect Your Eyesight

These days movies are all about explosions, drama, and action. Many new films are created with 3D, and recent advances in television technology have spurred the manufacturing of 3D TVs. Before you dive into 3D, be aware how it can affect your vision so that you can make the right eye care choices.

Technology of 3D

3D movies are filmed using two camera lenses. Originally filmmakers would use one red lens and one blue lens. The dual images were shot and overlaid, and looked like a double image unless you were wearing special glasses. These glasses combined both images and tricked the brain into seeing the movie as if items were actually flying toward you. Today, polarized lenses are used for filming, which greatly enhances the colors that could be used.

Pros of 3D Movies

Studies have shown that 3D movies help improve eye tracking in children who have problems with that function. Eye tracking is how well you follow a moving object with both eyes, and can cause socialization problems for children if it causes them to avoid sports activities and play. 3D movies have been shown to help kids track better, which even improves their reading abilities and learning.

Cons of 3D Movies

Visual issues such as blurred vision, double vision have been reported by people after watching 3D movies, as well as motion sickness symptoms. After watching a 3D movie, a person may have trouble refocusing on objects nearby. More often, watching 3D movies just highlights an existing vision issue. If you notice problems with watching 3D movies, consult your eye care professional right away.

3D movies are quite amazing. As with anything, moderation is the key. Talk to your Phoenix eye care specialist for more details on the effects of 3D movies on your vision.
