Why does eye movement behavior matter?
Involuntary eye movements — typically not apparent to the naked eye — indicate visual performance and health concerns. By measuring and analyzing these otherwise imperceptible patterns, doctors can identify and offer treatment to correct a host of vision and health issues as well as increase visual performance. Remember: vision is not the same as eyesight. A person with 20/20 eyesight may still exhibit weak eye movement behaviors.
What is eye-tracking technology?
Eye-tracking technology, which is both objective and non-invasive, captures pictures of eye movements (30-250) times a second. The data produced is quantitative—meaning, it allows physicians to identify vision and health issues in a measurable way. It can assess, and improve, the experiences of athletes. And it can track recovery and identify improvements.
What proof is there that eye-tracking technology is valid?
As far back as the 1980s, eye-tracking science and research languished in the halls of academia, only occasionally stepping out into the real world. Yet, during this time, vast amounts of health and vision research and testing created a cumulative understanding of how our eyes work and how they’re connected to the brain; how injuries and illness change how our eyes function; and how eye tracking training can aid in recovery and improve vision performance.

What year was the “E” eye chart developed?
1862. It’s called the Snellen chart after its inventor, the Dutch ophthalmologist Hermen Snellen. While today most doctors use the updated LogMAR chart, it does the same thing: measures how well we see at static images at a distance of 20 feet. Yet, because we primarily rely on vision while our eyes, bodies or objects are in motion, only about 5% of vision problems are identified with an eye chart. This is insufficient for everyone—children, in particular.
