Instigators and Risk Factors for Eye Phobia. Eye phobia in many (but not all) cases is triggered by a nasty experience in the past. In some cases, it appears the brain has produced the fear with no instigation. You resolve this issue by discovering the source and trading the negative correlations with positive ones.
But now, a study in the journal Psychological Science attempts to explain the fear. Researchers Geoff Cole and Arnold Wilkins of the Centre for Brain Science at the University of Essex based their research on images posted on Trypophobia.com. They've concluded that it is not the holes that these people fear. Instead, their brains associate the holes with danger. What kind of danger they sense, exactly, is still being studied. According to site, the fear covers clustered holes in skin, meat, wood, plants, coral, sponges, mould, dried seed pods and honeycomb.
