An eye coordination test, also known as a hand-eye coordination test, provides a look at the relationship between visual and physical responsiveness. An eye coordination test falls within the broader category of coordination tests, tests that focus on the ability to harmoniously move and control two different parts of the body. Eye coordination is a rudimentary motor skill that begins to develop from birth, and for proper vision the eyes have to work in harmony. Each eye sees a slightly different image, and the images are fused together in the brain to create one cohesive picture. The hands respond to these visual cues to carry out various tasks such as writing, reading, or catching a ball.
Typical signs of eye coordination problems include headaches, eye fatigue, and dizziness.

Annual eye exams are recommended as a part of preventative health care. Individuals can be unaware of problems because there are often no obvious signs or symptoms. It is important to detect and treat vision problems early in order to maintain good vision and eye health. Eye exams may include:
Patient History – Checks the patient’s general health, medication usage, family history and symptoms, etc.
Visual Acuity – Evaluates how clearly each eye is seeing. Also known as the “Snellen Chart”, this tests distance and near vision. Normal distance visual acuity is 20/20. If you have 20/20 vision, you are seeing clearly at the appropriate distance. This is only an indication of visual clarity and other skills that contribute to overall vision.
Preliminary Tests – Evaluates specific aspects of visual function and eye health.
Keratometry – Measures the curvature of the cornea, the clear outer surface of the eye. This is important for determining the “base curve” of the contact lenses.
Refraction – Determines the appropriate lens power to compensate for nearsightedness, farsightedness or astigmatism.
Eye Focusing, Eye Teaming, and Eye Movement Testing – Asses accommodation, ocular motility and binocular vision to determine how well the eyes function individually and together.
Eye Coordination – Ability of both eyes to work together. The brain fuses the images each eye sees in order to create one clear picture. Eye coordination is a developed skill and done properly, keeps the eyes in proper alignment. Poor eye coordination is often successfully treated with eyeglasses or the correction of other eye conditions, such as nearsightedness and farsightedness.
Eye Health Evaluation – Examines the external parts of the eye, including the cornea, eyelids, conjunctiva and surrounding eye tissue. In addition, the patient’s pupils may be dilated to evaluate the internal parts of the eye, including the lens, retina and posterior section. Doctors will also measure the pressure within the eye to detect glaucoma.
Supplemental Testing – Additional testing to confirm or rule out possible problems, and to provide clarification or further assessment.
