How is back to front an apparent anomaly that may crop up as you watch people’s eye movements?
Some people are completely reversed in their eye patterns. That is, their eye movements are like mirror images of the diagrams above. This is most often observed in people who are left handed, and very rarely in right-handed people. Some observers reckon that about half of left-handed people have reversed eye patterns, so this is a small percentage of the population, maybe around five per cent.
This reversal is consistent. For example, you will never find that someone is reversed in their visual quadrants but normal elsewhere.
