Binocular visionBinocular visionIn biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings.https://en.wikipedia.org › wiki › Binocular_visionBinocular vision - Wikipedia dysfunction (BVD) is a condition where the two eyes are misaligned and therefore don't have the same line of sight. This means the brain receives two different images, which it attempts to fuse into one clear 3D image.
What is BVD optometry?
Optometrists refer to binocular visionbinocular visionIn biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings.https://en.wikipedia.org › wiki › Binocular_visionBinocular vision - Wikipedia dysfunction as BVD, which is a visual condition where the line of sight from one eye is out of alignment with the line of sight of the other eye. This misalignment of the eyes can be vertical, horizontal, or at an angle in nature.
Can glasses correct BVD?
Luckily, there is treatment Specialized glasses with microprism lenses can address BVD and eliminate your symptoms. In fact, the average patient will notice a 50% reduction of symptoms by the end of their first visit with prismatic eyeglasses.
How do you treat BVD in the eye?
The way in which BVD is treated is through using bespoke prisms which are incorporated into your glasses or lenses. These will effectively displace the image that one eye sees so that it matches up perfectly with the other eye, counteracting the misalignment that the patient usually experiences.
What causes BVD in eyes?
BVD can be caused by several different factors. Some people experience BVD due to facial asymmetry, where one eye is physically higher than the other. It can also be caused by a nerve or eye muscle abnormality, which is something many people are born with.
How do I know if I have BVD?
What Are the Signs of BVD? Sudden bouts of dizziness and headaches that vary in intensity are two of the most common indications of BVD. Headaches are usually concentrated in the temples and the front of the face while the dizziness can make you feel lightheaded and unbalanced.

What does BVD mean on my eye prescription?
BVD stands for back vertex distance and is the distance in millimetres between the front of your eye and the lens of your glasses. This distance can influence the effective strength of a lens and is usually only given for higher-strength prescriptions.
Can you wear contacts with BVD?
No. At this time, contact lenses do not have the ability to realign the images like spectacle lenses with prism, and are not recommended for full-time wear. They can be worn for short periods of time (like for a special event or sporting activity), but only prism glasses adequately reduce or eliminate BVD symptoms.
How do you fix BVD in your eyes?
BVD is successfully treated with specific optical lenses called 'prism lenses' and vision therapy.
How is BVD measured?
the distance from the back of the lens to your eye (the back vertex distance, or BVD). This is needed if your prescription is relatively strong and will be written on your prescription.
