Visual Stress Assessments

Helping Make Reading More Comfortable

At Spectacle World, we understand that some children and adults experience discomfort when reading, even when their eyesight has been fully corrected. Words may appear to move, blur, shimmer, or lose focus, making reading more difficult and tiring than it should be.

Visual stress is a condition that can affect reading comfort and visual performance. It is often associated with symptoms such as headaches, eye strain, light sensitivity, difficulty concentrating on text, and reading fatigue. Our visual stress assessments are designed to identify whether visual factors may be contributing to these symptoms and to explore potential solutions that could improve reading comfort.

What is Visual Stress?

Visual stress describes a range of symptoms that can occur when looking at high-contrast patterns, particularly black text on a white background. Some individuals may experience:

  • Words appearing to move, blur, or distort
  • Difficulty tracking lines of text
  • Headaches when reading
  • Eye strain and fatigue
  • Sensitivity to bright light or glare
  • Losing their place while reading
  • Reduced reading comfort and concentration

Visual stress can affect both children and adults and may impact reading confidence, educational performance, and everyday visual comfort.

Visual Stress Screening with the Thomson Readez Test

As part of our assessment process, we may use the Thomson Readez Test, a recognised screening tool designed to investigate symptoms associated with visual stress.
The assessment typically involves:

  • Reading specially designed passages of text
  • Measuring reading speed and accuracy
  • Trialling different coloured overlays
  • Comparing reading comfort and performance with and without colour

The Thomson Readez Test provides a structured and objective way to assess whether colour may improve reading comfort for certain individuals.

Who Can Benefit from a Visual Stress Assessment?

A visual stress assessment may be beneficial for children and adults who experience:

  • Headaches during reading
  • Reading fatigue
  • Glare sensitivity
  • Difficulty concentrating on text
  • Words appearing to move or blur
  • Reduced reading confidence or comfort

The assessment can be particularly helpful when symptoms persist despite having an up-to-date prescription and healthy eyes.

Understanding the Results

The Thomson Readez Test is a screening tool and does not diagnose dyslexia, autism, or learning difficulties. However, it may help identify individuals who experience visual discomfort when reading and who could benefit from visual adaptations such as coloured overlays or other management strategies.

As part of our assessment, we will also ensure that any underlying vision problems are identified and addressed through a comprehensive eye examination where appropriate.
