Understanding Your Blink Test Results

Learn about the metrics recorded from your MBI analysis including blink rate, interval, and duration measurements.

After completing the Blink Test, you will see a detailed report with measurements of your blink patterns.


Key Metrics Explained

Maximum Blink Interval (MBI)

What it measures: The longest duration of time between two consecutive blinks during the test.

Measurement unit: Seconds


Average Blink Rate

What it measures: The number of times you blinked per minute, on average.

Measurement unit: Blinks per minute (bpm)

Factors that affect it:

  • Screen time
  • Environmental conditions (wind, dry air)
  • Concentration level
  • Current activity

Symmetry Score

What it measures: The consistency of your blinking between your left and right eyes.

Scoring: Percentage from 0-100%


Average Blink Duration

What it measures: The average amount of time your eyes were closed during each blink.

Measurement unit: Milliseconds (ms)


Clinical Metrics Dashboard

The results also include a "Clinical Metrics" section with additional measurements:

Spontaneous Blinks

Definition: Normal, natural blinks that occur without conscious effort.

Measurement: Percentage of total blinks


Partial Blinks

Definition: Blinks where the eyelid did not fully close over the eye.

Measurement: Percentage of total blinks


Average IBI (Inter-Blink Interval)

Definition: The average time between all blinks throughout the test.

Measurement unit: Seconds


IBI Variability

Definition: A measure of how consistent the timing is between your blinks.

Measurement: Statistical variation in timing
