Abstract:

An optometer is described that makes use of polarized light. It is similar in construction and use to the better-known laser optometer but is less expensive, avoids some problems inherent in using lasers, and is responded to very well by subjects in behavioral research. Uses of the device are discussed, and the laser and polarized optometers are contrasted. It is concluded that the polarized vernier optometer is an economical and effective alternative to the laser optometer in behavioral research settings. Author
