Common Eye Conditions That Can Cause Double Vision

Double vision can be unsettling, especially when it happens suddenly or starts interfering with reading, driving, work, or daily activities. Also called diplopia, double vision means you are seeing two images of one object. It may happen all the time, come and go, or appear only when looking in certain directions. At Visionary Eye Care, we help patients understand whether double vision is related to eye alignment, focusing, neurological concerns, or another vision condition that needs attention.

What Double Vision Can Feel Like

Double vision may appear side by side, one image above the other, or slightly tilted. Some people also notice eye strain, headaches, dizziness, poor depth perception, or trouble focusing. In some cases, symptoms may be worse when reading, using a computer, driving at night, or moving through busy environments. Because double vision can have different causes, a NeuroVisual ® Exam is an important first step.

Binocular Vision Dysfunction

Binocular Vision Dysfunction, or BVD, is one common cause of double vision. BVD happens when the eyes are slightly misaligned and the brain has to work harder to combine two images into one clear picture. Even a small misalignment can create uncomfortable symptoms.

BVD may cause double vision, headaches, dizziness, motion sensitivity, neck pain, reading fatigue, and poor depth perception. Some patients may still have 20/20 vision but struggle because their eyes are not working together comfortably.

Strabismus

Strabismus occurs when the eyes do not point in the same direction. One eye may turn inward, outward, upward, or downward. This can lead to double vision in adults because the brain receives two different images.

In children, the brain may suppress one image to avoid double vision, which can increase the risk of amblyopia, sometimes called lazy eye. Early evaluation is important for protecting long-term vision and comfort.

Eye Muscle or Nerve Problems

The eyes rely on muscles and nerves to move together accurately. When one or more of these muscles or nerves is affected, the eyes may not align properly. This can happen because of trauma, inflammation, neurological conditions, diabetes, stroke, or other medical concerns. Double vision that appears suddenly should be evaluated promptly, especially if it happens with weakness, facial drooping, severe headache, dizziness, confusion, or trouble speaking.

How Double Vision Is Diagnosed

A double vision evaluation may include checking visual acuity, eye alignment, eye movement, focusing ability, depth perception, and overall eye health. At Visionary Eye Care, our NeuroVisual® Exam goes beyond a standard eye test by looking at how the eyes work together, including movement, focusing, posture, and balance. For patients with BVD, custom prism lenses may help align the images sent to the brain and reduce strain on the eye muscles.

Get Answers About Your Double Vision

You should schedule an eye exam if double vision is frequent, worsening, or affecting your comfort and safety. It is also important to be evaluated if double vision comes with headaches, dizziness, balance problems, eye pain, or changes after a concussion or head injury.
