A progressive addition lens (PAL) is a seamless multifocal lens with the distance power in the top half of the lens that gradually increases in power as the wearer looks down into the bottom portion of the lens. This design allows for clear distance, intermediate and near vision. In order to achieve this lens design, unwanted astigmatism is created in the lower quadrants of the lens. The inability to adapt to this peripheral distortion prevents some presbyopes from wearing PALs. Numerous…

TLDR
The VisionPrint system (VPS) can effectively be used to assess ocular motor function by objectively calculating a person’s head versus eye movements, leading to a diagnosis of ocularMotor dysfunction.

TLDR
Nonphysical variations in eliciting gaze shifts likely determine gain in different laboratories; gain is reliable if measured on a relative scale among similarly tested subjects.
