3D Glasses and their effect on your vision

A Look At D Glasses And Your Eyes

With a lot of movies, 3D entertainment is making a comeback. The marketplace also offers 3D Glasses, televisions, gaming systems, and networks to satisfy the increasing thirst.

This availability begs the question: What is the impact of watching 3D movies on your vision? Let’s take a look at the answers.

What types of 3D Glasses exist?

There are two types: active and passive.

  • Active 3D Glasses have an electronic component that constantly blacks out the left or right lens, effectively showing a single image to each eye. They are best for wearing inside your home or in a small setting.
  • Passive 3D Glasses don’t have any electronic components. Instead, they work by filtering the images, typically using a polarizer, so each eye receives a different picture. The left lens receives images from a clockwise polarizer, while the right one gets an anti-clockwise.

Different 3D Experiences

Each person will react differently to 3D entertainment. You may, for example, love watching 3D because of the added depth perception. Your friends, however, may have a different experience. That’s because they may develop headaches, nausea, or eye fatigue during or after seeing the movie.

You can attribute the differences in 3D experiences to each individual’s visual ability. For example, to enjoy 3D, a person must have binocular vision and the ability to put both eyes together.

But some people have marginal binocular vision, which means that both their eyes can perceive 3D images with more difficulty. About 5 percent of the population have monocular vision, where they see pictures using only one eye.

For others, seeing 3D images on small and big screens causes headaches, eye fatigue, and nausea. In addition, the ability to enjoy 3D movies will be adversely affected by the eyes’ tendency to be misaligned. When one of the eyes cannot focus well, the 3D images also swim.

Available Therapy for Folks

Fortunately, a few therapies are available for people with monocular and marginal binocular vision problems. It would be best to ask your eye doctor at Walmart for more information about these therapies.

In the case of marginal binocular vision, your eye muscles likely have coordination issues. Your eye doctor can recommend vision therapy, a set of special techniques. In addition, you will learn techniques for improving your eyes’ coordination, such as prolonged viewing of 3D images.

You will initially experience headaches and nausea. But the technique can be effective since your eyes learn to adjust. As a result, your next time viewing a 3D movie will likely be more enjoyable.

Other techniques to adapt your eyes to 3D Movies

You can also adopt the 20-20-20 rule. After watching a 3D movie for 20 minutes, look away for 20 seconds and focus your eyes on an object 20 feet away. Your eyes can enjoy a break from the 3D images and even become more adept at seeing them.

If you have the money for it, you may also wear customized 3D glasses. Instead of wearing standard 3D glasses on top of your regular glasses, these have your prescription in place.
