Binocular Vision Dysfunction (BVD) occurs when the eyes are not properly aligned, which means the line of sight from one eye does not coordinate with the line of sight from the other eye. This misalignment can be very small, often going undetected in standard eye exams, but it can still cause a variety of symptoms due to the strain it places on the visual system. Common symptoms of BVD can include:

• Pain-Related Symptoms: Frequent headaches, discomfort in the sinus and eye regions.
• Postural Issues: A tendency to tilt the head, potentially leading to neck and back pain. Prolonged head tilt may result in asymmetrical facial features and a furrowed brow on one side.
• Vestibular and Balance Challenges: Experiences of dizziness, imbalance, motion sickness, impaired depth perception, coordination difficulties, and a tendency to veer to one side while walking.
• Reading Difficulties: Quick onset of fatigue during reading, challenges in maintaining attention, frequent skipping of lines, losing one’s place, and words appearing to merge.
• General Visual Discomfort: Eye strain, difficulty seeing at night, blurred vision, and challenges with tasks requiring close focus.
• Binocular Vision Strain: Symptoms like double vision, reliance on one eye for reading, and heightened sensitivity to light.
• Psychological Impact: Increased anxiety in crowded or expansive spaces, indicative of the broader effect of BVD on overall well-being.

Each of these symptoms reflects the varied impact of BVD on daily activities and underscores the importance of proper diagnosis and management.
