Eye tracking is an essential part of how we read, learn, and interact with visual information.

When your eyes move across a page or follow a moving object, they rely on precise and coordinated movements.

In Calgary, where reading, screen use, and schoolwork are part of daily routines, inefficient eye tracking can make these tasks more difficult than they should be.

At Eye Check Calgary, we often see patients who are working harder to read or focus without realizing that eye movement is part of the problem.

WHAT ARE SACCADIC AND PURSUIT EYE MOVEMENTS

There are two main types of eye movements involved in tracking.

Saccadic movements:

• Quick jumps from one point to another
• Used when reading from word to word or line to line

Pursuit movements:

• Smooth, continuous movements
• Used to follow moving objects, such as a ball or scrolling text

Both types of movements need to work efficiently for comfortable reading and visual processing.

WHAT HAPPENS WHEN EYE TRACKING IS NOT WORKING PROPERLY

When saccadic or pursuit movements are not functioning efficiently, the eyes may struggle to move accurately or smoothly.

This can lead to difficulty keeping place on a page or following visual information.

Common challenges may include:

• Skipping lines or losing place while reading
• Re-reading the same lines
• Slow reading speed
• Difficulty copying from a board
• Trouble following moving objects

These issues can affect both children and adults, especially during tasks that require sustained visual attention.

SIGNS OF SACCADIC AND PURSUIT DYSFUNCTION

Eye tracking problems are not always obvious, but certain signs can suggest an underlying issue.

You may notice:

• Difficulty maintaining place when reading
• Using a finger to guide reading
• Poor reading comprehension
• Eye fatigue during near tasks
• Short attention span when reading
• Avoidance of reading or schoolwork

These symptoms are often mistaken for learning or attention challenges rather than vision-related issues.

HOW EYE EXAMS IN CALGARY EVALUATE EYE TRACKING

Standard vision tests may not assess eye tracking in detail.

At Eye Check Calgary, we perform comprehensive evaluations to understand how the eyes move and work together.

This includes:

• Assessing saccadic accuracy and speed
• Evaluating smooth pursuit movements
• Measuring eye coordination and alignment
• Testing focusing ability during near tasks
• Examining overall eye health

These assessments help us identify whether eye tracking dysfunction is contributing to reading or focus difficulties.

HOW EYE TRACKING PROBLEMS ARE MANAGED

Management depends on the type and severity of the issue, as well as the individual’s needs.

Approaches may include:

• Vision therapy exercises to improve eye movement control
• Prescription lenses when appropriate
• Strategies to support reading and visual tasks
• Ongoing monitoring of progress

The goal is to improve how efficiently the eyes move and process visual information.
