What is Binocular Vision Dysfunction?

Understanding Binocular Vision Dysfunction: What You Need to Know

 In this article, we'll shed light on what binocular vision dysfunction is, its symptoms, and how our experienced optometrists can help you overcome it for clearer, more comfortable vision.

What is Binocular Vision Dysfunction?

Binocular vision dysfunction, often referred to as BVD, is a condition where both eyes don't work together as a team as they should. Our eyes are designed to work in harmony, allowing us to see a single, clear image. When this coordination breaks down, it can lead to a range of visual discomfort and challenges.

Common Symptoms of Binocular Vision Dysfunction:

  1. Eye Strain and Fatigue: Individuals with BVD often experience eye strain, headaches, and fatigue, particularly when reading or performing close-up tasks for extended periods.
  2. Depth Perception Problems: Reduced depth perception can lead to difficulties with judging distances, making activities like catching a ball or parking a car more challenging.
  3. Poor Concentration: BVD can impact concentration and the ability to maintain attention, especially during tasks that demand visual focus.
  4. Frequent Loss of Place While Reading: Reading can become frustrating when the eyes don't work together, causing words to appear to jump around or lose their place on the page.
  5. Light Sensitivity: Some people with BVD may also experience increased sensitivity to light, known as photophobia.

How Can We Help?

Our experienced optometrists are highly trained to diagnose and treat binocular vision dysfunction. Through a comprehensive eye examination, we can identify the underlying issues causing your discomfort. Treatment options may include:

  1. Prescription Lenses: In some cases, specially designed eyeglasses or contact lenses can help improve binocular vision and reduce symptoms.
  2. Vision Therapy: Vision therapy exercises and activities can be tailored to retrain and strengthen neuro-muscular function, enhancing binocular vision and visual comfort.
  3. Lifestyle Adjustments: Our optometrists can also provide guidance on ergonomic changes and habits that can reduce eye strain and discomfort in your daily life.


If you're experiencing any of the symptoms mentioned above, it's essential to schedule an appointment with our skilled optometrists. We are dedicated to improving your vision and overall eye health, helping you enjoy clear, comfortable, and seamless binocular vision once again. Don't let binocular vision dysfunction hold you back from living life to the fullest. Contact us today to schedule a consultation and take the first step toward better vision.

Myopia Awareness Week 22-26 May 2023

Myopia control is important because it allows parents to take proactive steps in managing and slowing down the progression of their child's shortsight. By working with the Optometrists at Harmony Vision to implement myopia control measures, parents can be assured that they are helping to take control of their child's eye health journey.

Why is this important?

Well, by actively addressing and controlling myopia, we can potentially reduce the risk of future eye problems for children, such as retinal detachment, cataracts, and glaucoma. It's our responsibility to safeguard our child's eyes for a healthier future.

Furthermore, myopia control has a significant impact on children’s daily life. By managing the progression of myopia, we can help our children maintain clearer vision without constantly needing stronger glasses or contact lenses. This empowers them to fully engage in activities, excel academically, and enjoy hobbies with improved visual clarity.

To achieve myopia control for your child, you can work with the Optometrists at Harmony Vision who will guide you in choosing the right strategies. This may involve specific glasses or contact lenses, eye drops, encouraging outdoor activities, and managing screen time effectively.

As parents, we have the opportunity to be the driving force in our child's eye health journey. By embracing myopia control, we actively shape the outcome of our child's vision and overall well-being. This requires a dedicated and proactive approach together with Harmony Vision to contribute to a brighter future for your child's eyes.

How Do You Get Myopia Management?

We assess your child's vision and axial length and consider other risk factors like age, family history, current level of myopia and lifestyle to develop an individual plan for managing your child's myopia.

Children’s Vision – Chat to Your Teacher

The importance of talking with teachers to identify vision issues

A child’s ability to learn is intimately related to their vision. At school, 80% percent of what your child will learn is obtained visually. Think about it, most of their learning happens in front of a whiteboard, computer or book. How the brain and eyes work together has a tremendous impact on the learning process.

Why is vision so essential to learning?

In school, your child will be using a wide range of visual skills including:

  • Distance vision: being able to see the board
  • Near vision: being able to look at the words in a book without effort
  • Focusing flexibility: being able to maintain clear vision while shifting focus from a distant object to a near one
  • Tracking/eye movement skills: being able to aim both eyes accurately and move smoothly across a line of print or from object to object with ease
  • Eye-hand coordination: being able to use their eyes to guide the hands
  • Eye teaming: being able to coordinate the two eyes together so that they are precisely directed at the same object at the same time
  • Eye focusing: maintaining, for long periods of time, completely clear vision while looking at near or distant objects

    The Rise of Digital Eyestrain and How to Avoid It

    The Rise of Digital Eyestrain and How to Avoid It

    Digital devices have become part of our everyday lives. We use them for work, study, reading, playing and communicating with loved ones. For many of us, our

    devices are the first things we greet in the morning and the last thing we use at night.

    While there is no doubt that they have made some part of our lives easier and more convenient, they are also contributing to health issues, and one of those is digital eye strain.

    What is Digital Eye Strain?

    It was only a generation ago that only a small part of the population spent a lot of time reading or on a computer-like device. What was once the realm of the “geek” or bookworm, is now the norm for a much larger part of the population. Increased use of technology and digital devices means an increase in the amount of time spent relatively still while looking at near distances for long periods of time. This is not something our eyes were designed to so constantly and results in visual fatigue and eyestrain symptoms.
