Abstract

An adjustment device adapted to glasses each including two polarization filters having adjustable transmission axes varying an angle therebetween in a front view is constituted of a physical parameter receiving unit for receiving at least one physical parameter which is produced by measuring the user's body, an angle calculation unit for calculating a target angle to be formed between the transmission axes of the polarization filters based on the received physical parameter, and a polarization filter adjustment unit for rotating at least one of the polarization filters, thus making the present angle formed between the transmission axes of the polarization filters agree with the target angle. Thus, it is possible to reduce a load or strain imparted to a user's eyes in light of the user's fatigued condition.
