Eye Tracking and How it Affects Our Vision

Most people find it hard enough just to keep track of their everyday lives with all the pressures, demands, and to-do lists associated with it. And that’s merely keeping up to date with routines. It’s way harder for one in four of the global population, whose eyes can’t team up enough to track what they are seeing at any given time. And that’s with regard to everything they see, but it’s specially so when they’re trying to read, or make sense of where and how fast a moving ball is going, according to Gary Rodney, Australian Master of Optometry and Fellow of the International Academy of Orthokeratology and Myopia Control (FIAOMC).

Rodney says it is quite normal that faces are not always the same shape on both sides,  usually people’s ears aren’t either, and chances are that a person’s eyes will also not be identical in shape or size. And they may have a certain amount of difference in their refractive powers. But this becomes a problem if the eyes function even slightly out of sync and move and focus differently. This can lead to problems with vision, physical health, learning, and perception, and it can possibly leave a person uncertain of their physical place in, and relationship to, the world.

When the Messages Get Confused

Among the most common of deficits in students’ vision skills, eye tracking (also called ocular motility or oculomotor function) concerns the two eyes’ ability to move up and down and from side to side simultaneously, and shift their eye alignment accurately from one object to another in a way that the two eyes can provide an understandable single visual image between them, says Rodney.

The effort required in the brain to make this happen can have huge impacts on concentration levels and abilities to process information at a higher level in the brain. Poor functional vision skills can impact in the same way making it difficult to carry on a conversation and ride a bicycle up a hill. How the eyes collaborate (or don’t) with one another in terms of these movements, can completely change the way a person sees, as well as how much they understand or perceive of what they are seeing.

Total teamwork is necessary because the data about what is being seen is received from light rays which enter each eye individually, and each send separate electrochemical messages to the brain for processing. These are seen by the brain as two different views of the same object and blended into one image. If the two eyes don’t project the same data about the colour, location and texture as well as other means of reference used by the brain, this could lead to confusion, distraction and inability to get a meaningful understanding of what is being seen.

Results of Tracking Dysfunction

When eyes aren’t able to operate as a team a long list of health issues and a great deal of discomfort may follow in the form of acknowledged symptoms like nausea, headaches, dizziness, light sensitivity, and blurry vision; as well as feelings of disorientation and being off balance when walking, which may lead to clumsiness or a tendency to bump into things.  Pain in the face and neck are also commonly experienced, and the eyes themselves may be sore due to the strain put on them during the struggle to balance their focus. 

Eye teaming and eye tracking problems can also lead to learning and reading issues, impacting on fluency, comprehension and speed when reading. This may result in misdiagnoses when it comes to learning difficulties such as dyslexia, which could toughen the chances of effective treatment for about one of every three who have been diagnosed with dyslexia.

If any of the following patterns are adopted they could be possible signs that a child has eye tracking problems, which, according to Rodney, can only really be identified through in-depth testing.

  • Eye Teaming deficits may cause text or individual words to appear to “float” or “move” on the page because of the viewer’s inability to focus properly when eye movement is involved.
  • Reaction to Reading: If children are overwhelmed by pages of text; avoid or resist reading; and prefer to be read to, rather than read themselves; they may have tracking difficulties. When they do read, they may find it easier to do so if the font is large, but have a slow and halting reading pattern when they read out loud.
  • Physical Response to Reading: Those with tracking problems may squint or rub their eyes frequently, tilt their heads or move them from side to side, and/or use their finger as a guide to keep track of where they are in the text when reading.
  • Outcome In Reading: They may guess at words they can’t identify, and lose their place when reading, writing, or copying (especially when their eyes are in the return sweep phase). Other tell-tale signs are if they leave out or transpose words or sentences when reading ( particularly if the words are small or similar), or they tend to re-read words or sentences.
  • Writing: Signs there might be problems include poor handwriting, inaccuracy when it comes to word endings, low awareness of punctuation, and a tendency to reverse words or letters. Those with tracking issues may also they have difficulty when copying from the white board.
  • Sports: Poor sports performance (particularly when playing games which involve moving objects, may also be a result of tracking difficulties.
