Can Eye Strain Cause Dizziness? Optometrist

83% of Americans use digital devices for at least 2 hours daily. 32.4% of those Americans experience eye strain.

When we ask if eye strain can lead to dizziness, the short answer is yes, it can. Eye strain, medically known as asthenopia, occurs when your eyes get tired from intense use, such as staring at a computer screen or driving long distances. While eye strain itself is often more of a discomfort than a serious condition, it can sometimes contribute to dizziness—a feeling of lightheadedness or unsteadiness.

Additionally, eye strain may also be accompanied by other symptoms such as headaches, blurred vision, and nausea, which can all contribute to or be mistaken for dizziness. It’s important to note that while dizziness can stem from eye strain, it can also indicate other health issues. Therefore, persistent dizziness should not be dismissed and should prompt a visit to an eye care professional for a thorough examination.

Connection Between Vision and Balance

The human body maintains balance through a complex interplay between the vestibular system in the inner ear, the proprioceptive system (which tells us where our body is in space), and our vision. These three systems send signals to the brain to help us navigate and interact with our environment.

Our eyes play a crucial role in this balance system. They provide the brain with visual cues that help us understand our surroundings and how we are moving within them. For instance, when you walk, your eyes send signals to your brain about the path ahead, any obstacles in your way, and the speed at which you are moving.

If the eyes are not functioning optimally due to strain, the visual information they send to the brain may be compromised. This can lead to a miscommunication between the eyes and the brain's balance centers, which can result in a feeling of dizziness or instability.

Furthermore, certain eye conditions can directly impact balance. For example:

  • Binocular Vision Disorders: Normal vision aligns and focuses images from both eyes to create a single, cohesive view. When this alignment is off, due to conditions like strabismus or convergence insufficiency, the brain receives conflicting signals. This misalignment can lead to difficulty in merging the two images into one, which can be disorienting and affect one's sense of balance, sometimes causing dizziness or even double vision.
  • Vision Impairment: Our visual system plays a critical role in how we interpret the space around us. When vision is compromised through conditions like severe myopia (nearsightedness), hyperopia (farsightedness), or diseases that affect the field of vision such as glaucoma, the brain doesn't receive a full picture. Specifically, the loss of peripheral vision can severely disrupt one's ability to navigate environments, leading to missteps and a feeling of imbalance or disorientation.
  • Eye Movement Disorders: Smooth and coordinated eye movements are essential for tracking moving objects and for stabilizing our vision as we move through our environment. Disorders that affect eye movement, such as nystagmus (where the eyes make repetitive, uncontrolled movements) or ocular motor dysfunction, can interrupt the stable flow of visual information. This disruption can challenge the brain's ability to process movements, causing a sensation of spinning or swaying, contributing to balance difficulties and dizziness.
How Can a Neuro-Optometrist Help with Eye Strain and Dizziness?

How Can a Neuro-Optometrist Help with Eye Strain and Dizziness?

Expert Assessment

A neuro-optometrist specializes in the relationship between visual function and neurological processes. When you visit with complaints of eye strain and dizziness, they perform a thorough examination, going beyond routine vision tests to assess how your eyes communicate with your brain. This can reveal issues like binocular vision dysfunction that standard exams might miss.

Personalized Vision Therapy

If a neuro-optometrist determines that your dizziness is related to a vision alignment issue or a condition such as convergence insufficiency, they may recommend vision therapy. This therapy is a personalized program designed to correct the specific visual anomalies causing strain and, by extension, dizziness.

Guidance on Visual Hygiene

Neuro-optometrists provide advice on visual hygiene, which includes tips on proper lighting, screen time management, and exercises to strengthen the visual system. They'll guide you through practices that reduce eye strain, thereby diminishing the likelihood of dizziness.

Assistive Devices and Lenses

They can also prescribe specialized lenses or prisms that can help alleviate eye strain. For those with presbyopia, they may suggest solutions like contact lenses designed to reduce strain when focusing on close objects.

Rehabilitation for Neuro-Visual Issue

For patients experiencing dizziness following a traumatic brain injury, a neuro optometric evaluation can be crucial. It can help your eye doctor understand the connection between the traumatic brain injuries and visual symptoms and can provide rehabilitative services to address them.

Preventing Eye Strain and Dizziness

Preventing Eye Strain and Dizziness

Understanding the Risks

Prevention starts with understanding what causes eye strain and, potentially, dizziness. Extended use of digital screens, reading without adequate lighting, or dealing with untreated vision problems can all be culprits. By identifying these risk factors, you can take proactive steps to minimize them.

Ergonomic Workspace Design

Creating an ergonomic workspace is crucial. Position your computer screen so the top is at or slightly below eye level. Choose chairs that support your posture, and place documents at a comfortable reading distance to avoid hunching forward. Good ergonomics not only help prevent eye strain but also reduce the risk of dizziness by promoting better blood flow and posture.

Healthy Visual Habits

Adopting healthy visual habits is another key strategy. Follow the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. Also, ensure you're blinking often enough to keep your eyes moist and avoid dry eye syndrome, which can contribute to eye strain.
