The brain compensates for the loss of vision

Scientists have solved the question of why people lose their ability to distinguish different shades of color without knowing it.

The bad news is that most of us will experience color blindness over time. The good news is that almost no one is paying attention to this situation, thanks to the "overtime" of the brain .

Scientists found that elderly people lost their ability to distinguish colors, because cones lost their ability to process information.

However, at the same time, other parts of the vision system work harder to minimize this situation, according to the University of Liverpool (UK) study, monitoring 185 people aged 18 to 75 with eyesight. normal.

They found that the ability to assess color in volunteers seemed unaffected by age, according to ABC News.

However, in reality it is different, for example, the ability to distinguish small changes in different shades of color is changed over time, especially with yellow - green in daylight conditions.

The study author Dr. Sophie Wuerger concluded that the brain has reconnected, to ensure that the color recognition function is stable from young to old.
