Abstract

Power deposition in the head of a user wearing metal-framed spectacles was calculated with a 450MHz personal radio transmitting in close proximity. Peak tissue SAR in the head depended on lens shape - whether circular half-rim or rectangular - with 70 and 174 increases, respectively, compared to the spectacle-free case. However, localised screening occurred with square frames, with a 40 reduction of peak SAR in the eye closest to the antenna.
