Abstract: A device for accommodation training includes a primary light and a sensor supported by a housing and configured to be worn atop the head of the user to capture light reflected by the retina. One or more alignment lights may be provided, along with mounts for adjusting the positioning of the lights and sensor. A feedback signal such as an audible tone is produced as a function of the detected light, providing confirmation to the user that a desired control over the ciliary muscle has been achieved.

Abstract: Accommodation training apparatus is modified to include electroencephalography apparatus for monitoring the patient's brainwaves. This permits a patient to be trained to enter, and to remain in, the alpha state, even with the eyes open and with something to look at.A two-dimensional CCD matrix is used to receive reflected-back radiation from the eye. A computer is connected to the matrix and permits the patient to be trained for correction of conditions such as strabismus, nystagmus and eccentric fixation by identifying whether the patient's eye is moving or whether the patient's state of accommodation is changing.An LCD matrix is used to present variable visual information to the patient's eye. This facilitates training the patient for dichotic learning.Advantageously, electromyography apparatus is used to monitor the tension of one of the patient's muscles, advantageously the frontalis muscle.

Abstract: Methods and apparatus for monitoring and training eye position under clinical conditions are provided in accordance with the teachings of the present invention. An infrared optometer is employed to measure a patient's corneal and retinal reflection and outputs therefrom are employed to generate tone information and viewable patient information indicative of eye position and the state of focus. A patient is trained until a predetermined proficiency in the voluntary control of eye position is achieved.

Abstract: Methods and apparatus for performing accommodation training under clinical conditions are provided in accordance with the teachings of the present invention. An infrared optometer is employed to measure a patient's accommodation and outputs therefrom are employed to generate tone information and viewable patient information indicative of the state of focus in a rapid manner. A patient is trained at an empirical rate determined by the viewable information until a predetermined proficiency in the voluntary control of accommodation is achieved. Thereafter, stimuli to accommodation, the accommodation convergence reflex and blur cue information are selectively introduced to generalize the voluntary control of accommodation achieved to a conventional environment so that the same may serve to reduce various visual acuity problems in a patient being trained.

Abstract: Optometer apparatus for directly measuring the refraction of the eye and methods therefor are provided in accordance with the teachings of the present invention. According to an exemplary embodiment of the present invention, a double slit, Scheiner principle projection system is employed to project an image upon the retina. The retinal image is then focused upon an optoelectric, linear sensor which provides an output corresponding to the intensity gradient of the retinal image focused thereon. The output of the optoelectric, linear sensor may then be employed as a measure of the refraction of the eye.
