Abstract : The present invention relates to optometers and particularly to a Scheiner-principle optometer apparatus, and method therefor, for measuring the resting state of accomodation, and for providing cognitive recognition of this accommodative state in order to facilitate bio-feedback training of that accommodative state. The need for precise lens accommodation to bring visual targets into sharp focus on the retina is far more urgent at night when contrast is very low, than in bright daylight. Unfortunately, it is at precisely this time that many individuals become myopic and further reduce the quality of an already poor visual image. Keywords: Patent applications. (jes)
