VISUAL EFFICENCY EXAM

CHILDREN & BINOCULAR VISION

What is a Visual Efficiency Exam?

A visual efficiency exam is a series of tests that evaluate a patient’s vision skills with particular emphasis on the following:

  • Visual acuity: clarity of sight at distance and near
     

  • Refractive status: tests to determine whether glasses are needed for myopia (nearsightedness), hyperopia (farsightedness), and/or astigmatism. 
     

  • Accommodative function: ability of the focusing system to maintain clear vision at various distances.
     

  • Binocular function: the ability of the two eyes to work efficiently  as a team
     

  • Oculomotor function: eye tracking ability

Who Might Need a Visual Efficiency Exam?

Generally, a comprehensive eye examination (with dilating drops) performed by your eye care professional is required prior to a VEE. Based on patient's signs and symptoms suggestive of binocular vision, focusing and/or eye tracking problems, a VEE may provide valuable information in diagnosis and treatment.

Types of Visual Efficiency Exams

What are typical treatment options?

Your doctor will review the information collected and may recommend any combination of these treatments:

  • Prescription eyeglasses for full time wear

  • Eyeglasses with prism (which can help the two eyes to work together more easily)

  • Vision therapy (a program that improves vision skills through a series of prescribed activities)
