Irlen Glasses

autismtwo

When I go into shops, especially supermarkets I get dizzy or if there is bright lights, even the sun in my eyes,, I get dizzy, it is like I am half drunk. My balance goes off. I was thinking maybe I am light sensitive.. researching,, I came across Irlen Glasses which are filter lens of some type.

Anyone know anything about this, is it a path worth exploring. I always assumed the dizzy spells were anxiety related, but could it be light sensitivity ?

  • We have a specialist optical practice that routinely assesses visual processing problems associated with light sensitivity.

    There is a lot that can be done, for example - optometrists have a duty of care to recognise when a filter or tint needs to be prescribed (in children at any rate as they are the only people legally entitled to precribe for clinical need in children).

    Opticians usually choose the filter. To be able to do this they have to know the tolerances of colour, saturation (how much white is present) and brightness, combine it with the task, reflectance, absorbsion and ambient lighting and be aware of all the cross sensory problems that can be present e.g. balance and hearing difficulties, coordination, headaches etc. It is very complex and choosing by trial and error is unlikley to be be very good - especially for those with profound problems. There are techniques available but these are few and far between in practices - especially as the best instrumentation is usually necessary (the gamut is critical)

    However the training is at present extremely limited as it has not been considered a priority - and may only be addressed by some optical professionals as a reading speed difficulty - which is of little value in ASD. The greatest effects are in facial recognition / expression recognoition, sensory synchronisation /integration and cognition. 

    The system does need to change - maybe it will someday. But changing a profession is difficult.

    A bit of advice - expert knowledge is critical - you may have to travel
