I will not tutor a new pupil without assessing them first with the appropriate Lucid test. I cannot speak highly enough of their ease of use, speed, accuracy and fun content.

Lucid ViSS

Visual stress, which affects 15 – 20% of the population, hinders children's literacy development and is a barrier to efficient and enjoyable reading. ViSS gives an accurate and reliable indication of the existence and severity of visual stress and identifies those who may benefit from using coloured overlays or tinted lenses to combat the symptoms of visual stress.

After screening with ViSS
The administrator’s manual that accompanies the software contains a number of interventions to support those susceptible to visual stress.

Speedy and easy to use

  • requires minimal supervision
  • takes 20 – 30 minutes
  • suitable for ages 7 to adult
  • Results show susceptibility to visual stress – from 'low' to 'extremely high'

Results show the degree of difficulty that the person experienced with the visually stressful items relative to the visually unstressful items. Because results are compared across the two different conditions,,the individual speed of working is immaterial.

What is visual stress?

Visual stress (sometimes called 'Meares-Irlen Syndrome' or 'Scotopic Sensitivity Syndrome') is the experience of unpleasant visual symptoms when reading. Symptoms include illusions of shape, movement and colour in the text, distortions of the print, loss of print clarity, and general visual irritation. Visual stress can also cause sore eyes, headaches, frequent loss of place when reading, and impaired comprehension. Around 15 – 20% of people suffer visual stress to some extent, and they also tend to be hypersensitive to fluorescent lighting and flicker on computer monitors. Visual stress is not the same as dyslexia, but dyslexia does seem to exacerbate the symptoms of visual stress so it is especially important that those with diagnosed dyslexia are screened for visual stress.
