Abstract
This application discloses systems and methods for automated vision testing. Performing automated vision testing can be beneficial in a number of eye care applications due to the reduction of chair time, increase of the measurement accuracy, elimination of human errors, capability for internal instrument calibration, and the possibility for test standardization.
Claims20
A system for performing automated vison testing, the system comprising:
- a display device system configured to present one or more stimuli to one or both eyes of a tested subject;
- an input device configured to record responses of the tested subject;
- an analysis system configured to analyze the responses and to present a result of the vision test being performed;
- and
- one or more optical components, wherein a plurality of stimuli viewing distances is achieved by arranging the system with different configurations of the one or more optical components,
- wherein at least one of the one or more optical components is a curved mirror,
- wherein the one or more optical components includes a second mirror, an optical path of the one or more stimuli including the curved mirror or the second mirror by actuating the curved mirror or the second mirror into and out of the optical path, and wherein a viewing distance of the system changes as a consequence of which mirror is in the optical path of the one or more stimuli.
