Visual Stress
Visual stress refers to a range of symptoms that can occur when the brain has difficulty processing visual information. Common signs include headaches, eye strain, fatigue while reading, or words appearing to move or blur on the page. It is often associated with reading difficulties, including dyslexia, and can significantly impact daily life if left unaddressed.


Overlay Assessment
An overlay assessment involves testing coloured overlays – transparent sheets placed over text – to determine whether they help reduce symptoms of visual stress. Many individuals experience immediate relief and improved reading fluency when using the correct colour overlay. At Makerfield Eye Centre, we provide comprehensive overlay assessments to identify the most effective solution for you or your child.
