With Avatar and other movies, 3D entertainment is making a comeback. The marketplace is also offering 3D televisions, gaming systems, and networks to satisfy the increasing thirst for it.
This begs the question: What is the impact of watching 3D fare on your eyes? Let’s take a look at the answers.
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, no thanks to their headaches, nausea, or eye fatigue during and/or after seeing the movie.
The differences in 3D experience can be attribute to each individual’s vision ability. For a person to enjoy 3D fare, he must have binocular vision, the ability to both eyes together.
But there are people who have marginal binocular vision, which means that both their eyes can perceive 3D images but with greater difficulty. Many people – about 5 percent of the population – have monocular vision, a condition where only one eye is used in seeing images.
In both cases, seeing 3D images on the small and big screens cause headaches, eye fatigue, and nausea. The ability to enjoy 3D movies will be adversely affected by the eyes’ tendency to be misaligned, too. When one of the eyes cannot focus well, the 3D images also swim, so to speak.
Available Therapy for Folks
Fortunately, there are a few therapies available for people with monocular and marginal binocular vision problems. You should ask your eye doctor at Walmart for more information about these therapies.
In case of marginal binocular vision, your eye muscles likely have coordination issues. Your eye doctor can recommend vision therapy, a set of special techniques. You will learn techniques in 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. Your next time viewing a 3D movie will likely be more enjoyable.
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, even become more adept at seeing them.
If you have the money for it, you may also wear customized 3D glasses. These are designed with your prescription in place so that you don’t have to wear standard 3D glasses on top of your regular glasses.
