Just because you undergo routine eye exams does not mean that you know everything about the function of your visual system. You need to understand that a standard eye exam might not be enough to identify Binocular Vision Dysfunction (BVD).  

There are many different conditions that can affect our eyes and vision. One that isn’t well known but that is extremely common is binocular vision dysfunction, or BVD.

Binocular vision dysfunction or BVD is a visual condition that results from both eyes failing to coordinate properly. It makes the line of sight slightly misaligned from one eye to the other. The eye misalignment stresses the eye muscles as they attempt to correct the issue to achieve a single, focused vision.  

Binocular Vision Dysfunction, or BVD, is a problem with the alignment of your eyes. Our eyes work together to produce vision, but in order for them to produce a single, clear image, they need to work in perfect synchronization. This means that they need to be aligned in the same plane.When the eyes are misaligned, your brain and eyes have to work much harder to try and turn the individual images seen by each eye into one, single image. This places a great deal of pressure onto the trigeminal nerve – the largest nerve in the brain, and the nerve that is responsible for most of the sensations that we experience in both our head and neck.The thing with BVD is that it causes a wide range of different symptoms. These can come and go, range in severity, and may vary in which ones you experience. Some of the most common symptoms associated with binocular vision dysfunction include: 

Migraines are headaches that often cause severe pain, and they usually occur on one part of the head. Some people experience a pulsing sensation with the throbbing pain. Migraines are often accompanied by vomiting, nausea, and extreme sensitivity to sound and light.  

You’ve probably heard of vertigo. Most people think of conventional vertigo, which is a symptom rather than a condition in its own right. It can last anywhere from a couple of seconds to a few hours or more. Some people who experience chronic vertigo can find that they suffer repeated episodes for months or even years.

Headaches are very common, but when you suffer from them regularly, they can have a particularly debilitating effect on your quality of life. However, you may be surprised to learn that fixing the problem could be easier than you might think. Chronic headaches are regularly misdiagnosed when actually, they can often be a result of a condition called binocular vision dysfunction, or BVD for short. 

Motion sickness is the name used to describe nausea and/or vomiting that occurs in people traveling by car, boat, plane, or train. It is extremely common, with studies suggesting that as many as 1 in 3 people are highly susceptible to the condition. This risk could be even greater if you also suffer from another issue called binocular vision dysfunction, or BVD for short.   

Do you get particularly stressed or anxious while driving? Do you dread getting behind the wheel, feel short-tempered or feel excessively tired after even a short journey? If so, your eyes could be the cause of your problem.Many people can become nervous or anxious while driving. The reason for this is the exposure to visual stimuli. While we are surrounded by visual stimuli all day long, when we are driving, the effects are much more significant. Things are moving past us at speed, requiring our eyes and brain to work together much more quickly to determine what we are seeing and to react to it if necessary. We also need to use much greater concentration as our safety, and that of people around us, relies on us being focused and interpreting the things that we see correctly.Some of the visual stimuli present when driving include:

Binocular Vision Dysfunction, or BVD for short, is a very common condition that occurs when the eyes aren’t perfectly aligned. As a result, they can’t work in perfect synchronization easily, which can cause painful and debilitating symptoms. It may not be considered a serious condition, but it can have a tremendous impact on various areas of your day-to-day life.
