All or some of the following symptoms may be present:

  • Movement of the printed text
  • Blurring of print
  • Letters changing size or shape
  • Patterns in the print (sometimes described as rivers or worms)
  • Halos of colour surrounding letters or words
  • Tiring easily whilst reading

The Signs of Visual Stress

  • Moves closer to or further away from the book
  • Moves book around on the desk
  • Fidgets continuously
  • Using finger as a marker on the page
  • Skips words or lines
  • Frequently re-reads the same line
  • Rubes eyes or blinks frequently when reading
  • Poor comprehension of reading content
  • Frustration and low self-esteem

Frustration and low self esteem can occur in children who are underachieving due to visual stress. Early diagnosis of the problem is essential. The longer it takes to identify and remedy visual stress, the greater the loss of confidence that can result.

 

 

 

 

 

Visual Stress and Photosensitive Migraine

Migraine attacks have many triggers, including stress, particular foods, and hormones. About 40% of migraine attacks may be visually induced by flickering light, patterns or reading. These attacks may be helped by precision tinted lenses.

Research in the US undertaken recently by a team of neuro-scientists, using brain imaging, has shown that a suppression of hyper-excitability in the visual cortex occurs in migraineurs when individually selected precision tinted lenses are worn.

The lenses for the study were selected using the Intuitive Colorimeter. Symptoms of other neurological conditions such as Autism, MS, ME and Parkinson’s have been shown to reduce with the application of a precise colour.
