Why does bright light in classrooms, malls, outside and at night affect me and give me headaches?

Light sensitivity is often a symptom of Irlen Syndrome - a perceptual processing disorder and not an optical problem.
Light sensitivity can be a symptom on it’s own but I often find that if light sensitivity is the main problem, then once a short Irlen test is completed you’ll find other Irlen symptoms are also occurring. 
In my case I realised I read more slowly without my Irlen coloured overlay or Irlen lenses.  This is because without the light frequencies being filtered the white on the page is too bright and bits of white come through the print – this slows my reading speed!
 
One of my clients reported after wearing new Irlen lenses ‘the frightening brightness of the sun's light, especially in the middle of the day is wonderfully controlled.  I can read the computer screen without difficulty; the mobile phone seems to have been tamed. The Kindle responds beautifully to the new lenses and is kind on the eyes.’
 
 
 
Can light sensitivity be so severe that you also may experience headaches and migraines?
 
A client was having massive headaches, which could not be explained by optometrists or neurologists. She even had a scan but nothing showed up.  Another client had unexplained and intense headaches when he was studying and working before his Irlen diagnosis.  Both clients thought they couldn’t have Irlen Syndrome because they were ‘academic’ and could read well.   Being able to read well and being ‘academic’ doesn’t mean you don’t have Irlen syndrome, these clients just have to work extra hard to get through their workload.  Both these clients have been tested for Irlen Syndrome and now have Irlen coloured lenses.  Their lenses are hardly ever off!  Headaches are gone!
 
 
Why is night driving scary?
 
Driving at night can be really difficult  - as one client said – she needs to ‘look away’ when oncoming cars approach to allow her to tolerate the glare from oncoming headlights!  The new LED lights that are in cars, as well as many traffic lights, particularly bother her.  Added to this any white, middle road marking lines disappear!
With her Irlen lenses her light sensitivity is controlled.  Her life is going to be so much better now, as she will not be experiencing the regular migraines that she normally gets every day.
Do the self-test to see if your migraines or headaches could be the result of light sensitivity related to Irlen Syndrome.
