Jaw Alignment and Visual Perception: How TMJ Disorders Affect Your Vision

Temporomandibular joint (TMJ) disorders are a collection of conditions that affect the jaw joint and surrounding muscles. While commonly associated with jaw pain and difficulty with jaw movement, TMJ disorders can also have an impact on several other aspects of your health. One such aspect is visual perception. This article explores how TMJ disorders can affect your vision, as well as the importance of jaw alignment in promoting optimal visual function.

Understanding TMJ Disorders

TMJ disorders refer to a variety of conditions that involve dysfunction of the temporomandibular joint, which connects your jawbone to your skull. These disorders can arise from various factors, including trauma or injury to the jaw, teeth grinding (bruxism), arthritis, or misalignment of the jaw joint. Common symptoms of TMJ disorders include:

  • Jaw pain or tenderness
  • Clicking or popping sounds when opening or closing the mouth
  • Difficulty or pain while chewing
  • Locking of the jaw
  • Headaches
  • Earaches or ringing in the ears
  • Facial pain

The Link Between TMJ Disorders and Visual Perception

The relationship between TMJ disorders and visual perception may not be immediately apparent. However, recent research has uncovered a connection between the two. The temporomandibular joint is located in close proximity to various important structures, including the nerves and blood vessels in the face, jaw and eyes. Any dysfunction in the jaw joint can lead to tension and inflammation in these structures, which may impact visual processing.

One study published in the journal Physiological Reports found that individuals with TMJ disorders displayed abnormalities in their visual perception abilities compared to patients who are not affected by these disorders. The researchers observed that those with TMJ disorders had reduced visual contrast sensitivity and slower visual reaction times. Visual contrast sensitivity refers to the ability to distinguish between shades of light and dark, while visual reaction time measures the speed at which the brain processes and responds to visual information.

Another study published in the Journal of Oral Rehabilitation investigated the impact of TMJ disorders on eye movements during visual tasks. The researchers found that individuals with TMJ disorders exhibited altered eye movement patterns, with increased fixation durations and reduced saccades (rapid eye movements) compared to individuals without TMJ disorders. These findings suggest that TMJ disorders may affect the coordination and efficiency of eye movements, potentially resulting in decreased visual performance.

Jaw Alignment and Visual Function

The alignment of your jaw plays a crucial role in maintaining optimal visual function. When the jaw is misaligned, it can create an imbalance in the muscles that control eye movement, leading to strain and fatigue. This can result in symptoms such as eye discomfort, blurred vision and difficulty focusing. Additionally, the tension and inflammation caused by TMJ disorders can also affect blood flow to the eyes, further impairing visual function.

Seeking treatment for TMJ disorders and addressing jaw alignment issues is essential in minimizing the impact on your vision. A qualified dentist or orthodontist can evaluate your jaw alignment and recommend appropriate treatment options. This may include orthodontic interventions, bite splints or oral appliances, physical therapy, or, in severe cases, surgical corrections.

Additional Tips for Maintaining Healthy Vision with TMJ Disorders

Alongside professional treatment, certain self-care measures can help support healthy visual function in individuals with TMJ disorders:

  • Practice good posture: Maintaining correct posture can alleviate strain on the neck, shoulders and jaw, promoting better eye alignment and reducing visual discomfort.
  • Take breaks: If you frequently engage in activities that require prolonged visual focus, such as reading or working on a computer, take regular breaks to rest your eyes and relax your jaw muscles.
  • Use warm compresses: Applying warm compresses to the jaw area can help relax tense muscles and reduce inflammation, potentially alleviating symptoms that may impact visual perception.
  • Avoid excessive jaw movements: Limit activities that involve excessive jaw movements, such as chewing gum or biting nails, as these can exacerbate TMJ symptoms and potentially affect visual function.


While TMJ disorders are primarily associated with jaw pain and dysfunction, their impact extends beyond the immediate area. Visual perception can be affected by these disorders, highlighting the importance of maintaining proper jaw alignment and seeking appropriate treatment options. By addressing TMJ disorders and optimizing jaw function, individuals can improve their visual performance and enhance overall quality of life.
