Visual stress, also known as Meares-Irlen Syndrome, is a condition that affects how the brain processes visual information. It can lead to discomfort, difficulty reading, and other visual disturbances. While not classified as a learning disability, it often coexists with conditions like dyslexia and attention deficit disorders. This article will guide you through the causes, symptoms, diagnosis, and management of visual stress.
What is Visual Stress?
Visual stress refers to the sensory overload that occurs when the brain struggles to interpret visual stimuli. It can be triggered by high-contrast patterns, small or crowded text, bright lights, or specific colours. People with visual stress often describe the sensation as words or letters "moving," "swirling," or "vibrating" on the page, making it hard to read or concentrate.

Common Symptoms
Visual stress can manifest in various ways, including:
- Reading Difficulties: Letters may appear blurred, distorted, or crowded.
- Physical Discomfort: Eye strain, headaches, or migraines, especially after extended periods of reading or screen use.
- Light Sensitivity: Difficulty tolerating bright lights, glare, or fluorescent lighting.
- Fatigue: Feeling unusually tired after visually intensive tasks.
- Concentration Issues: Difficulty maintaining focus on text or tasks that require prolonged visual effort.
Who is Affected?
While anyone can experience visual stress, it is more common in:
- Individuals with dyslexia or other learning difficulties.
- People with migraines or light sensitivity.
- Children and adults who spend extended time reading, studying, or working with digital screens.
What Causes Visual Stress?
The exact causes of visual stress are not fully understood, but several factors contribute to the condition:
- Neurological Sensitivity: Some people have a heightened sensitivity to visual stimuli, making their brains process information inefficiently.
- Lighting and Screen Use: Bright, flickering, or blue light from screens can exacerbate symptoms.
- Font and Text Layout: Small fonts, narrow line spacing, and high-contrast black-and-white text often trigger discomfort.
Diagnosing Visual Stress
Diagnosing visual stress involves a combination of:
- Recognizing symptoms like difficulty reading, headaches, or light sensitivity with our symptom tracker.
- Ruling out underlying eye conditions with a comprehensive eye exam.
- Assessing responses to coloured overlays or lenses during reading tasks with our colour demonstrator.
Consulting a specialist at Vision Through Colour who may use tools like the Wilkins Rate of Reading Test or Irlen Screening to evaluate visual processing issues.
Managing Visual Stress
There are several ways to reduce the impact of visual stress:
- Use of Coloured Overlays: Transparent overlays in specific colours can reduce distortion and improve reading comfort.
- Tinted Glasses: Prescription or non-prescription lenses with a specific tint can help filter out problematic wavelengths of light.
- Optimize Reading Material
- Increase font size and spacing.
- Use off-white or pastel-coloured backgrounds instead of stark white.
- Adjust screen settings to reduce glare and brightness.
- Lighting Adjustments: Replace fluorescent bulbs with softer, natural lighting or use lamps with adjustable brightness.
- Frequent Breaks: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
- Seek Specialist Support: Neuro-optometrists, occupational therapists, or Irlen practitioners can provide targeted therapies and tools to alleviate symptoms.
Can Visual Stress Be Prevented?
While it may not always be possible to prevent visual stress, these strategies can help minimize its effects:
- Create a comfortable workspace with appropriate lighting and ergonomics.
- Avoid prolonged screen time without breaks.
- Adjust screen and text settings to suit your preferences.
Living with Visual Stress
With the right support and interventions, people with visual stress can manage their symptoms effectively. Whether it’s using tinted glasses, optimizing lighting, or taking regular breaks, small adjustments can significantly improve comfort and productivity.
If you or someone you know experiences persistent visual discomfort, consulting a professional for a thorough assessment is an essential step toward relief.
Visual stress doesn’t have to interfere with daily life. By understanding its causes, recognizing its symptoms, and seeking the right interventions, you can create a more comfortable and supportive environment for reading, learning, and working.
