AMBLYOPIA - A condition where the vision in an eye is poor even with the best optical correction.

ASTIGMATISM - Due to an irregular shape of one part of the eye, objects focus in two points instead of just one, causing a blur.

BINOCULAR VISION DISORDER - Difficulty using the eyes as a team.

CONVERGENCE INSUFFICIENCY - A condition in which the person has difficulty bringing the eyes inward, at near, for skills such as reading.

CONVERGENCE EXCESS - A condition in which the eyes converge too much causing difficulty in turning the eyes outward.

CRANIAL NERVE PALSY/ PARALYSIS - A condition where a nerve that controls a muscle is partially or completely damaged causing moderate to complete loss of muscle function.

DIVERGENCE INSUFFICIENCY - A condition in which a person has difficulty moving the eyes outward, causing eyestrain and/or diplopia.

DIVERGENCE EXCESS - A condition in which the eyes diverge too much, causing eye strain and /or diplopia.

DIPLOPIA - Looking directly at an object and seeing double.

ESOPHORIA - A tendency for the eyes to turn inward, but with effort can remain straight.

ESOTROPIA - A condition where one or both eyes turn inward. (crossed-eyed)

EXOPHORIA - A tendency for the eyes to turn outward, but with effort can reamin straight.

EXOTROPIA - A condition where one or both eyes turn outward. (wall-eyed)

FUSIONAL DISORDER - A condition i nwhich the eyes have difficulty teaming together.

HYPEROPIA - Farsightedness - it takes more effort to see near than far.

HYPERPHORIA - A condition in which one eye has a tendency to point higher than the other.

HYPOPHORIA - A condition in which one eye has a tendancy to point lower than the other.

HYPERTROPIA -  A condition where one or both eyes point higher and remain seperate.

MYOPIA - Nearsightedness - It takes more effort to see objects far away.

NYSTAGMUS - Constant jerky eye movements, one or both eyes, usually side to side.

OCULAR PURSUIT DISORDER - A reduced ability of the eyes to easily and accurately follow moving objects.

POST TRAUMATIC VISION SYNDROME - Visual disturbance caused by trauma (i.e. blunt trauma, stroke, tumor, etc.).

SACCADIC EYE MOVEMENT DISORDER - A condition in which any of the rapid jumps made by the eyes from one fixed point to another is difficult (as in the reading process).

STRABISMUS - An eye turn or misalignment of one or both eyes, constant or intermittent, in which they point in different directions.

STREFF NON-MALINGERING SYNDROME - Near vision poorer than distant vision, poor focusing skills, little or no eyeglass prescription problems.  Physiological or psychological stress.

SUPPRESSION - A condition where the brain ignores all or part of the information being sent from one eye, thus seeing with one eye when both eyes are open.

VISUAL PERCEPTION DISORDER - Difficulty processing visual information in the brain.
