A number of other gadgets and appliances have also been trialled with the intention of tricking the brain to improve body perception, such as prism glasses and minifying lenses.
Prism glasses are based on the principles of mirror therapy, but were designed to allow portable treatments which can be performed more regularly.
Bultitude and Rafal (2010) provided a single case report of a patient with early CRPS managed with prism glasses and mirrors.
Through the neuro-optometric evaluation, prescriptions can be made for various types of lenses and
prism glasses that can counter the effect of visual midline shift.
Brain hurt remark-- In May 2014, The Washington Blog post reported that Republican politician planner Karl Rove "distanced himself from a provocative record in Monday's New York Post, stating he doesn't believe-- as the paper insisted he had actually informed-- that Clinton suffered 'mental retardation' when she went down and suffered a head injury in December 2012." Rove had actually been commenting on Clinton's
prism glasses.
