You eyes may be able to reveal more about you than you realise.
Scientists have created a 'mind-reading' AI that can predict your personality from looking at pupil movements and blinking.
Curious people tend to look around more and open-minded people stare at abstract images for longer periods of time, researchers revealed.

The eyes really are a window to the soul, according to scientists who have created a 'mind-reading' AI that can predict your personality from looking at small eye movements and blinking
Scientists, led by Tobias Loetscher from the University of South Australia, used machine learning to understand how eye movements and personality are related.
Forty-two students wore eye-tracking smart glasses while walking around campus, writes New Scientist.
The students also filled out questionnaires that rated their personalities.
This questionnaire broke down personality into the 'Big Five' traits used widely in psychology; extraversion, neuroticism, conscientiousness, agreeableness, and openness to experience.
'Personality traits characterise an individual's patterns of behaviour, thinking, and feeling', researchers wrote in their paper published in Frontiers in Human Neuroscience.
'Studies reporting relationships between personality traits and eye movements suggest that people with similar traits tend to move their eyes in similar ways.'
Researchers found that people who were neurotic usually blinked faster while people who were open to new experiences moved their eyes more from side-to-side.
People who had high levels of conscientiousness had greater fluctuations in their pupil size.
Optimists spent less time looking at negative emotional stimuli (such as image of skin cancer) than people who were pessimistic.
