ABSTRACT:
The present invention generally provides improved devices, systems, and methods for measuring characteristics of at least one eye, and particularly for measuring the physiological changes in eyes under different viewing conditions. An exemplary embodiment provides a pupilometer which measures any changes in location of a pupil center with changes in viewing distances. As the eye often moves significantly during viewing, the pupil center location will often be measured relative to a convenient reference of the eye such as an outer iris boundary. Pupil size may also be recorded, and the measurements from both eyes of a patient may be taken simultaneously. Exemplary embodiments may be configured so as to allow the vergence angle between the eyes to vary with differing viewing distances, regardless of whether one or both eyes are being measured.
