An optical device combination with a portable electronic device utilizes a user's autonomic response to truth/false or beneficial/non-beneficial stimulus and provides immediate feedback to the user in the context of an applied kinesiology exam. Through measurements of the pupils dilation or constriction and processing of the measurements by the portable electronic device, the response is obtained and feedback is provided that reflects the pupillary response.
|Apparatus and method for assessing effects of drugs by recording ocular parameters|
The invention is directed to quantification of the effects of drugs on a patient using pupillometric measures. Apparatus and processes for obtaining control and patient measures and deriving relationships from same are provided.
|Presbyopia lens with pupil size correction based on level of refractive error|
Ophthalmic lenses for the treatment of presbyopia may be improved to enhance the visual experience of the patient. By adjusting the optical design of presbyopic lenses to account for changes in pupil size due to the degree of myopia or hyperopia, an enhanced visual experience may be achieved independent of the level of ametropia..
