Visual
Stress (or Meares-Irlen syndrome)
Visual Stress (also known as Meares-Irlen
syndrome) is a visual
sensitivity triggered
by certain patterns (normally
black-white stripes eg
text or stripy shirts);
sufferers can have any
of the following symptoms
- movement/blurring
of print
- letters changing shape/size/contrast
- illusions of blobs/patterns/colour
runing through print
- rapid fatigue and
poor concentration
- headaches/eyestrain/glare
These symptoms can occur despite having
'perfect' sight and vary
in intensity in individuals. Approximately 5% of the population
are severely affected
by visual stress and 20%
to a lesser degree. This
means that up to 1 in
5 people are not necessarily
reaching their potential
when reading or working
with computer screens.
Research
at Essex University has
shown that Precision Tints
can have an instrumental
role in improving reading
skills, reducing screen
glare, generally improving
visual comfort, reducing
headache and tension,
improving concentration
and efficiency in those
prone to visual stress.
