Binocular vision dysfunction
When looking at objects within 1 meter, there are no issues.
However, beyond 1 meter, when both eyes focus on a single point, the images keep jumping back and forth, and the visuals alternate between the left and right eyes.
For instance, when watching television, the text appears to jump up and down uncontrollably.
There are also instances of double vision, such as when looking at the floor tiles, which seem to continuously shrink from the outside in.
It feels like the left and right eyes are unable to merge the images properly, and I am becoming increasingly distressed, almost to the point of developing depression due to these eye problems.
My left eye has a prescription of -6.25 with astigmatism of -3.00 at an axis of 10, and my right eye has a prescription of -7.25 with astigmatism of -3.00 at an axis of 170.
Should I see a neurologist for an examination?

Hello Mr.
Wei: Your condition is somewhat unusual.
Typically, when we focus on a certain distance, the dominant eye does not switch randomly.
It is quite strange that you keep switching and have double vision.
I recommend that you visit a large hospital to see an ophthalmologist who specializes in neuro-ophthalmology (not neurology) for an examination.

More Info
Understanding binocular vision dysfunction can be quite complex, especially when symptoms like double vision, jumping images, and difficulty focusing arise. These symptoms can significantly impact daily life and may lead to feelings of frustration or even depression, as you mentioned. Let's break down the potential causes and solutions for your situation.
Symptoms and Their Implications
From your description, it seems you are experiencing several visual disturbances when looking at objects beyond one meter. The jumping images and double vision (diplopia) can be indicative of a few underlying issues related to binocular vision dysfunction. This condition occurs when the eyes do not work together effectively, leading to problems with depth perception and clarity of vision.
1. Double Vision: This can occur due to misalignment of the eyes (strabismus), where one eye may be looking in a different direction than the other. It can also be caused by issues with the muscles that control eye movement or neurological conditions affecting the brain's ability to coordinate eye movements.
2. Jumping Images: This symptom may relate to a lack of proper fusion between the two images your eyes are sending to the brain. When the brain cannot combine these images into a single coherent picture, it can lead to the perception of images jumping or flickering.
3. Visual Distortions: The sensation of the floor tiles appearing to shrink or distort could be related to how your brain interprets visual information from both eyes. This could be exacerbated by the differences in refractive error between your eyes, as indicated by your prescription.
Potential Causes
Several factors could contribute to your symptoms:
- Refractive Errors: Your prescription indicates a significant difference in the strength of lenses needed for each eye. This disparity can lead to difficulties in merging images from both eyes, especially at greater distances.
- Neurological Issues: Conditions affecting the brain, such as multiple sclerosis, can lead to binocular vision dysfunction. If there are concerns about neurological involvement, it would be prudent to consult a neurologist for further evaluation.
- Eye Muscle Imbalance: If the muscles controlling eye movement are not functioning properly, this can lead to misalignment and double vision.
Solutions and Recommendations
1. Comprehensive Eye Examination: It is crucial to have a thorough eye examination by an ophthalmologist or optometrist who specializes in binocular vision disorders. They can assess your eye alignment, muscle function, and overall visual acuity.
2. Vision Therapy: If a diagnosis of binocular vision dysfunction is confirmed, vision therapy may be recommended. This involves a series of exercises designed to improve coordination and cooperation between the eyes.
3. Corrective Lenses: Adjusting your prescription to better balance the visual input from both eyes may help alleviate some symptoms. Specialized lenses, such as prism glasses, can also be beneficial in managing double vision.
4. Neurological Evaluation: Given your symptoms, it may be wise to consult a neurologist to rule out any underlying neurological conditions. They may recommend imaging studies or other tests to assess brain function and connectivity.
5. Mental Health Support: Since you mentioned feelings of depression related to your visual issues, seeking support from a mental health professional can be beneficial. They can help you develop coping strategies and provide support as you navigate these challenges.
Conclusion
Binocular vision dysfunction can significantly impact quality of life, but with the right diagnosis and treatment plan, many individuals find relief from their symptoms. It is essential to address both the physical and emotional aspects of your experience. By consulting with the appropriate specialists and exploring treatment options, you can work towards improving your visual function and overall well-being.
