Visual Stress & Processing Assessments at Chase Meadow Optic

Visual Stress, sometimes called Irlen Syndrome or Meares-Irlen Syndrome, is a condition that affects how the brain processes visual information. It can cause words or text to appear distorted, blurred, moving, or difficult to focus on. This can make reading, writing, or concentrating more tiring than it should be.

Research suggests that around 20% of children and many adults experience some degree of visual stress. It often goes unnoticed in standard eye tests, as many people assume that what they see is “normal.”

Visual Stress is sometimes linked with dyslexia or ADHD-like behaviours, but it can also occur on its own.

 People with visual stress may experience:

• Words that blur, move, or shimmer on the page
• Headaches, migraines, or eye strain when reading
• Sensitivity to bright lights, glare, or patterns
• Poor concentration or difficulty staying focused
• Fidgeting, squinting, or avoiding reading altogether
• Underachievement in reading, writing, or learning despite effort

If these symptoms sound familiar, a Visual Stress & Processing Assessment can help identify the cause.

 At Chase Meadow Opticians, our Visual Stress & Processing Assessments are designed to explore whether coloured overlays or tinted filters make reading more comfortable and effective.

1. Initial Eye Check – We first rule out any underlying vision or eye health concerns
2. Visual Stress Screening – You or your child will be shown text in different formats and colours to see if distortions occur.
3. Overlay Trial – We test different coloured overlays placed over text to find out if reading becomes easier. A reading speed improvement of just 5% or more can indicate a benefit.
4. Recommendations – Depending on results, we may suggest continued use of overlays, tinted paper, or tinted lenses for everyday tasks.

• Helps explain difficulties with reading or concentration.
• Provides practical solutions for school, work, or study 
• Can reduce headaches, eye strain, and visual fatigue
• Gives confidence and motivation back to those who may have been struggling

Every person is different, so our assessments are tailored to individual needs.
