What is vision?
Visual acuity and good eye health are critcal first steps, but they?re only a piece of a much larger visual puzzle.
20/20 vision is the ability to see a small image clearly at a specific distance, while functonal vision describes how your entire visual system - your eyes, your eye muscles and your brain - all work together to gather and process visual information.
Difficulty with any part of this functional visual system can lead to significant performance problems - even when seeing with 20/20 clarity.
