Vertigo is a spinning sensation that affects the vestibular system, which is responsible for providing the brain with information about head position, motion, and spatial orientation. While there are various causes of vertigo, one possible cause is eye strain, which can lead to dizziness, nausea, headaches, and visual disorientation. This occurs when the eye muscles are constantly working to align and correct themselves, resulting in a cycle of image misalignment and realignment. Additionally, conditions such as nystagmus, which involves rapid and uncontrollable eye movements, can also lead to vertigo. In some cases, the underlying cause of vertigo may be a brain disorder, and it is important to seek medical attention to identify and treat the specific cause.
| Characteristics | Values |
|---|---|
| Definition | Nystagmus is characterised by rapid, uncontrollable eye movements in one or both eyes. |
| Symptoms | Nystagmus symptoms include: shaky or blurry vision, balance problems, light sensitivity, trouble seeing in the dark, dizziness or vertigo, and oscillopsia (the feeling that stationary objects are moving). |
| Causes | Causes of nystagmus include: inner ear disorders (e.g. BPPV, Ménière’s disease), brain tumours, eye or head trauma, neurological disorders, certain medications, vision problems, and congenital abnormalities. |
| Treatment | Treatment options for nystagmus include: eyeglasses or contact lenses, prism lenses, medications (e.g. muscle relaxants, botulinum toxin injections), and in some cases, strabismus surgery to reposition the eye muscles. |
| Relation to Vertigo | Nystagmus can cause vertigo, especially when associated with oscillopsia. Vertigo can also be caused by eye strain due to misalignment of the eyes, leading to constant correction by the eye muscles, resulting in dizziness, nausea, and headaches. |

Eye strain and dizziness
Eye strain can also cause dizziness due to the connection between eye muscles and muscle tension in the head, neck, and shoulders. This tension can trigger headaches and contribute to feelings of dizziness. Furthermore, eye strain is often associated with subtle eye misalignment, which forces the eye muscles to constantly realign, leading to dizziness, nausea, and headaches. This condition is known as Binocular Vision Dysfunction (BVD) and affects about 20% of individuals in the US. BVD can result from facial asymmetry, nerve or eye muscle abnormalities, stroke, brain injury, or neurological disorders.
Visual information is crucial for balance and movement. Therefore, vision problems such as eye strain, blurred vision, or sight loss can lead to dizziness. Inner ear infections, for example, can affect balance and cause dizziness, making it challenging to focus the eyes. Additionally, conditions like nystagmus, characterized by rapid and uncontrollable eye movements, can result in dizziness and a spinning sensation (vertigo).
To alleviate eye strain and dizziness, it is recommended to follow the 20-20-20 rule: every 20 minutes, take a 20-second break and focus on something at least 20 feet away to relax the eye muscles. Maintaining proper posture, adjusting screen settings, and ensuring adequate lighting can also help reduce eye strain and associated dizziness.
While dizziness is unsettling, it is not an illness but a symptom of an underlying problem. If you experience frequent dizziness, it is advisable to consult a healthcare professional to identify and address any potential vision or health issues.

Binocular vision and vertigo
Binocular vision refers to the ability of both eyes to converge onto an object, sending two similar but slightly different images to the brain, which then combines them into one unified image. Binocular vision dysfunction (BVD) occurs when the eyes do not align properly, causing the brain to receive two competing images. This misalignment can be very subtle and is often missed on routine eye examinations.
BVD can be caused by facial asymmetry, nerve or eye muscle abnormality, stroke, brain injury, or neurological disorders. It can also be congenital or acquired later in life. When the eyes are misaligned, the eye muscles strain to correct the problem, leading to a variety of symptoms, including dizziness, vertigo, headaches, light sensitivity, motion sickness, and anxiety in large spaces. This cycle of image misalignment and realignment can put a great deal of strain on the eye muscles, leading to unpleasant and sometimes painful symptoms.
Visual vertigo is a phenomenon that occurs when too much visual stimulation triggers dizziness. It is often associated with binocular vision dysfunction and is commonly experienced when driving with a lot of stimulation on the side. The eyes become strained as they contract, trying to see better, which can lead to intense migraine-like headaches. Vertigo can also be caused by eye strain, which can be a result of the eye muscles constantly working to align and correct themselves.
The treatment for binocular vision dysfunction and associated vertigo can include specialized aligning micro-prism lenses to correct the misalignment and reduce symptoms. Prism lenses limit how much the eyes must move to see clearly. In some cases, strabismus surgery may be recommended to reposition the eye muscles, improving eye movement and reducing the need for head tilting or turning to see clearly.

Nystagmus and oscillopsia
Nystagmus is an involuntary, rhythmic side-to-side, up-and-down, or circular motion of the eyes resulting from a variety of conditions. It is characterized by rapid, uncontrollable eye movements in one or both eyes. It can be congenital or acquired later in life. Jerk nystagmus is the more common type, where the eyes drift slowly in one direction and then jerk back in the other direction. Pendular nystagmus, a rarer form, consists of to-and-fro quasi-sinusoidal eye oscillations.
Oscillopsia is the illusory sensation that the stationary visual world is moving. It is caused by a disturbance in the ocular motor system, which includes the vestibular ocular nystagmus saccade system, the pursuit system, the fixation and gaze-holding system, and the vergence system. These subsystems aid in stabilizing images on the retina during eye and head movements. When there is a disturbance in one of these systems, it can lead to instability of the eyes (nystagmus) or inadequate eye movement (bilateral vestibular failure), resulting in oscillopsia.
The treatment of nystagmus and oscillopsia depends on the underlying cause. In some cases, clearer vision can help slow the rapid eye movements associated with nystagmus, and eyeglasses or contact lenses may be recommended. Prism lenses can also be used to limit the amount of eye movement required to see clearly. In rare instances, strabismus surgery may be suggested to reposition the eye muscles and improve eye movement. While this does not cure nystagmus, it can reduce the need for head tilting and turning to see clearly. Additionally, medications such as gabapentin, baclofen, and onabotulinumtoxina (Botox) can help reduce nystagmus symptoms in adults.

Inner ear disorders
The vestibular system, which includes the inner ear, is responsible for balance and eye movement. If disease or injury damages these areas, vestibular disorders can occur. Inner ear disorders can cause vertigo, which is a spinning sensation or the feeling that surroundings are moving.
Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo and inner ear disorder. It is often caused by head injuries, which can damage drainage pathways and cause fluid buildup in the inner ear. Other common inner ear disorders include Meniere's disease, labyrinthitis, secondary endolymphatic hydrops, and perilymph fistula. Meniere's disease is characterised by episodes of vertigo, tinnitus (ringing in the ears), ear pressure or fullness, and hearing loss. Labyrinthitis and vestibular neuritis occur when the hearing and balance nerves become inflamed, resulting in sudden hearing loss, balance problems, and vertigo.
Superior semicircular canal dehiscence (SSCD) is a rare condition where there is a loss or absence of the bone covering the superior semicircular canal. SSCD can cause unusual symptoms such as pressure- or sound-induced vertigo, hearing loss, ear pressure, or even hearing one's own breathing and blinking.
Many environmental factors can damage the cells within the inner ear and cause hearing loss. One of the most significant factors is loud noise exposure, which can permanently destroy hair cells. Continued exposure to loud noise can lead to progressive damage and hearing loss and often results in tinnitus.

Eye muscle abnormality
One specific type of strabismus is infantile esotropia, where babies exhibit a significant inward turning of both eyes before they reach six months of age. This condition usually persists when the child looks up close or far away, and glasses typically do not correct the crossing. The treatment for infantile esotropia involves surgery on the muscles of one or both eyes to correct the alignment.
Strabismus can also be described based on the direction in which the misaligned eye points. For example, esotropia refers to when the eye points inward, while exotropia occurs when the eye points outward. These are forms of horizontal strabismus.
Another condition related to eye muscle abnormality is nystagmus, characterised by rapid, uncontrollable eye movements in one or both eyes. Individuals with nystagmus may experience symptoms such as blurry vision, balance problems, light sensitivity, and dizziness or vertigo. While some people are born with nystagmus, others may develop it later in life. It can be caused by various factors, including inner ear disorders, brain tumours, eye or head trauma, vision problems, or certain medications.
Eye strain caused by muscle abnormality can also lead to vertigo, a feeling of dizziness and disorientation. This occurs when the eyes are misaligned, forcing the eye muscles to constantly realign and sending conflicting signals to the brain. Specialized aligning micro-prism lenses can be used to correct the misalignment and reduce symptoms of vertigo.

Frequently asked questions
Vertigo is a spinning sensation that affects your vestibular system, which is a sensory system that provides your brain with information about head position, motion, and spatial orientation.
Any type of eye strain or issue can cause vertigo. When eye muscles are repeatedly working to align and correct themselves, it can lead to vertigo, along with nausea and balance issues. This is because any issue between the eyes and brain can create dizziness.
Vertigo is often accompanied by nausea, blurred vision, and headaches, making it difficult to go about one's day. It can also cause falls, which can lead to injuries.
Vertigo can be treated by performing the Epley maneuver, which involves placing your head in different positions to reset the balance organ. Physical therapy can also help improve balance problems. Prism lenses can be used to correct the misalignment and reduce these symptoms.
