A Visual Efficiency Evaluation examines the skills required to bring visual information to the brain. These skills include eye teaming, eye focusing, eye tracking and visual perception. An annual eye examination evaluates eye health and eyesight, but not visual skills.
Good eye teaming skills are needed to avoid blurry vision and seeing double, and to have proper depth perception. Eyes that work well as a team require no effort to maintain well-coordinated eye positioning when looking at an object.
When we look at something within an arm’s length we need good eye focusing skills to be able to see it clearly. Focusing should require very little effort, should be flexible, and should be accurate.
Eye tracking skills are needed to keep our place as our eyes move across the page while reading. We also need good eye tracking skills to follow moving objects such as a thrown ball, or when looking quickly from one object to another. Eye tracking should occur accurately with little to no thought.
Visual Perception is the ability to acquire, perceive and process what is in our environment. This skill is crucial for knowledge to develop in the academic setting.
Weaknesses with teaming, focusing, tracking or visual perception can cause symptoms such as:
- Eye strain
- Double vision
- Loss of place when reading
- Words moving around on the page
- Poor reading comprehension
- Avoidance of close work
- Loss of concentration
- Intermittent blurry vision
- Eyes feel tired when reading
- Poor academic performance in an otherwise intelligent child
The Visual Efficiency Evaluation is conducted by Dr. Amy Lambert. In preparation for your Visual Efficiency Evaluation, please ensure that your child has been using any glasses as prescribed by his or her optometrist, and be sure to bring them to the appointment. The evaluation lasts around two hours during which we play games and generally have fun. The testing can be physically tiring for the patient, so please make sure that he or she has eaten before the exam. Some patients may report a headache or eye strain afterwards. Rarely are dilating drops used as a part of the evaluation.
