Many friends and members of our Axon Optics Family suffer from Dystonia. Dystonia is a neurological movement disorder, in which sustained muscle contractions cause twisting and repetitive movements or abnormal postures. The basal ganglia are a group of structures found deep within the brain responsible for initiating muscle contractions. Dystonia seems to be related to a problem within these structures. Treatment for dystonia is intended to lessen muscle spasms and pain. If muscles around your eyes are affected, reducing eye strain and glare may help. We do not have any clinical data regarding our SpectraShield and dystonia. All of our non prescription frames have a 60 day return policy if you find them ineffective. I hope this helps.
