Human brain compensates for age-related color vision loss

Daily Mail : As humans age, the eye’s ability to distinguish colors diminishes. However, the effect goes almost unnoticed because of the brain’s ability to compensate for the loss. In a study published this week in the journal PLOS ONE, Sophie Wuerger of the University of Liverpool in the UK and colleagues looked at 185 people between the ages of 18 and 75, all of whom had normal color vision. They found that despite age-related yellowing of the lens of the eye, neural pathways in the brain are able to adjust so that people’s perceptions of color remain fairly constant over their lifetime.
