Modification of the Canon Auto Ref R1 for use as a continuously recording infra-red optometer.

Author information

Department of Physical Sciences, Glasgow College, UK.


The Canon Auto Ref R1 has been modified to allow continuous recording of accommodation while retaining its capacity to record in 'single-shot' static mode. Possible alternative principles of modification are discussed with emphasis placed on the method used in this paper. Preliminary results are presented for both a novel dynamic model eye and an emmetropic real eye. The system described provides a useful research tool in the study of ocular accommodation dynamics.
