Sudden Double Vision — Causes, Symptoms & Treatment

Sudden double vision can be frightening and come on without warning. It can be caused by serious conditions such as stroke or neurological problems. If you experience sudden double vision for the first time, you should seek medical attention to determine the cause.

Sudden double vision, or diplopia , occurs when the eyes do not synchronize properly, often without warning, and can be caused by brain trauma, stroke, or eye muscle paralysis. Symptoms of sudden double vision include eye fatigue, headache, and dizziness, which require immediate medical evaluation to rule out serious conditions.

What is sudden double vision?

Double vision means that the combined image from the eyes is not formed correctly, resulting in double vision. Medically, this is called diplopia. When both eyes send different images to the brain, a blurred visual experience is created. Sudden double vision can occur without warning, unlike chronic double vision which is more persistent.

When you have strabismus, each eye sends different images to the brain, which causes double vision. An imbalance between the eyes can cause you to see double. Symptoms such as latent strabismus can occur when the eyes drift apart when tired or stressed. Manifest strabismus means that the eyes are constantly pointed in different directions, which can lead to double vision.

Synapse , or the ability to combine images from both eyes, is crucial to avoiding double vision. When synapse is disrupted, binocular diplopia can occur. It is important to understand the difference between binocular and monocular diplopia, the latter of which only affects one eye. Identifying and understanding these differences is the first step toward proper diagnosis and treatment.

Common causes of sudden double vision

Sudden double vision can have several different causes depending on the individual and life situation. Common causes include:

  • Brain trauma such as concussion
  • Stroke
  • Neurological problems
  • Muscle paralysis in the eyes

These factors can affect the eye movement system and lead to double vision.

Concussion and trauma

Concussions are a common cause of temporary double vision. A concussion is a type of head trauma that can affect the body in several ways. When the brain is shaken violently, it can lead to disruptions in the eye movement system, resulting in double vision. This is because the brain is temporarily unable to process visual information correctly.

The effects of a concussion on vision can vary depending on the severity of the injury. In some cases, double vision may resolve on its own as the brain recovers, while in other cases, medical treatment and close monitoring may be required to ensure vision returns to normal.

Stroke

It is quite common to develop double vision after a stroke . A stroke can cause disruptions in the eye movement system, resulting in sudden double vision. This is because blood flow to the brain is interrupted, which can damage the areas that control eye movement. Strokes can also lead to acute eye muscle paralysis, which further worsens the double vision.

The sudden paralysis of eye muscles can be caused by stroke, inflammation, or tumors affecting the optic nerves. When the eye muscles do not function properly, the eyes cannot move in coordination, leading to double vision.

It is therefore important to seek medical care immediately if a stroke is suspected.

Symptoms to watch out for

Vision problems, eye strain, double vision, and headaches can occur with strabismus. When the eyes strain to see clearly, this can lead to headaches. Eye strain can also cause headaches and double vision, especially with prolonged use of computers or other visual concentration.

Dizziness is another symptom that can be experienced with sudden double vision and requires emergency care. Reducing headaches and fatigue can help prevent nausea associated with double vision and other symptoms.

If you experience these symptoms, it is important to contact an ophthalmologist to receive the correct diagnosis and treatment.

How VR training can help those suffering from double vision

With our method, you train your eye coordination by watching any streamed content. Through our patented technology, the film you choose to watch swings sideways and makes your eyes follow the same movement. This strengthens the cooperation between the eyes. In just a few weeks, you can feel the difference. Improved eye coordination can lead to the permanent disappearance of double vision.

Stream your favorite series in VR

You can easily train by watching streamed content via the Imvi app on your mobile phone that is in our VR glasses.

Workout while streaming your favorite shows

Through the app you choose what type of content you want to watch. We currently support content from Youtube, SVT Play, Binogi, UR Play and content directly from your phone's camera roll.

Train your consensus

The app makes the image stream oscillate from right to left. But your brain perceives it as a regular movie.

You watch series -
Our App does the rest

The training focuses on improving the brain's control of the eyes for better eye coordination. This improves blood flow and oxygenation of the brain, which increases reading speed, reading endurance and concentration.

Follow your progress

In the app you can easily follow your progress over time and receive recommendations for continued training.

Personalized tips based on your progress

In the app you can follow your or your children's development and results. We offer free accounts for parents to monitor their children's progress! After completing the training, you will receive personal recommendations for further training based on your results and progress.

Diagnosis of sudden double vision

Early diagnosis of double vision is important to avoid worsening of the condition and to enable better vision recovery. Different examinations are performed depending on the symptoms presented with double vision. Double vision can be a symptom of acute conditions such as stroke or eye muscle paralysis.

Neurological problems, including stroke or damage to the nervous system, can lead to double vision.

Eye examination

The doctor examines whether the eyes can move in all directions. This is an important part of the assessment. At the eye clinic, the doctor or orthoptist examines the mobility of the eyes and the direction of the eyes in relation to each other. Devices for examining eye muscles are rarely needed.

Neurological tests assess the function of the nervous system and can detect damage that affects vision. These tests can be crucial in identifying the underlying causes of double vision and in planning further treatment.

Neurological examination

A neurological evaluation involves a series of tests to determine the underlying causes of sudden double vision. An eye exam is essential to identify vision-related problems that may be causing double vision.

Imaging tests, including MRI and CT, are used to detect structural changes in the brain that can lead to double vision.

Treatments for sudden double vision

Available treatment options for double vision may include vision training , prism glasses, surgical procedures, and botulinum toxin. Imvi Labs has developed an effective method where you train yourself to eliminate double vision by watching movies in VR glasses.

It is important to seek medical attention if double vision develops rapidly, if one eye begins to cross, or if symptoms persist when one eye is covered. Early medical evaluation can be crucial in identifying underlying causes.

What can cause sudden double vision?

Sudden double vision can be caused by brain trauma, stroke, or eye muscle paralysis. It is important to seek medical attention if this occurs.

How can I get rid of my double vision?

There are several different treatment options for double vision. Vision training, prism glasses, surgical procedures are some examples. Imvi Labs' patented training that involves watching movies in VR has proven very effective in training to eliminate double vision.
