In particular, the game content engages both eyes at different levels of difficulty, forcing an amblyopic eye to work harder to regain its performance in the visual system. The invention herein described provides a mobile device, capable of interaction with an eye care specialist, for the assessment / treatment of binocular vision using innovative mechanisms for ensuring proper use thereof.

Methods and systems for treating presbyopia involve ablating a corneal surface of a first eye of a patient to enhance vision of near objects through a central zone of the first eye and ablating a second eye of the patient to enhance vision of near objects through a peripheral zone of the second eye.

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.

An information content difference between a left eye image and a right eye image is adjustable to achieve binocular vision in a patient having a deficiency of binocular vision. A source of image pairs is used along with a dichoptic display system to present a selected one of the images pairs as a right eye image to a patient's right eye and a left eye image to a patient's left eye. The difference at which a patient achieves binocular vision is a measure of a level binocular vision health or function, and continued exposure to the image pairs is therapeutic. The difference can be adjusted during therapy, and restoration of regular binocular vision is possible.

A binocular vision apparatus allows a patient to view objects through the apparatus with polychromatic light and monochromatic aberration correction, such that the chromatic aberration of the eye can be combined with the monochromatic aberration correction, so as to provide a more accurate determination of vision quality. The binocular vision apparatus provides left and right viewing optics that can substantially maintain the line of sight of each eye, such that objects can be viewed in a room with 3D depth perception corresponding to the distance of the object from the patient. As both near and far objects can be viewed with binocular aberration correction, the patient can alternate binocular viewing between near and far vision with chromatic aberration so as to evaluate a proposed treatment such as a presbyopia correction.

At present, when any myopia or amblyopia therapeutic apparatus which remedies two eyes synchronously by light is used for remedying, the affected eyes are all passive. Although the brightness of the relative lightening view points of two eyes from the apparatus are same, the feeling intensity towards the light of the affected eye is much lower than healthy eye, so the due curative effect of the original apparatus is influenced seriously. The present invention uses the method of adjusting the brightness of the relative lightening view points of left and right eyes respectively to increase the brightness of the relative lightening view points of the affected eye, and / or the brightness of the relative lightening view points of the healthy eye is reduced to reduce the light sensation intensity of the healthy eye, which ensures that the light sensation intensities of the left and the right eyes are in the balanced state, or the light sensation intensity of the affected eye is stronger than that of the healthy eye. Therefore, the method of the present invention can increase the chance and improve the capability of the affected eye of participating in exercise, participating vision and restoring the eyesight, which ensures the due curative effect of the original apparatus in the therapy theory.
