If you think that everything around you appears grey when you are sad, this might be a sign of depression, says a recent health report published by www.sciencedaily.com. The researchers at the Freiburg University, Germany conducted a new research to find out the response of the retina to the different black and white contrasts.
The researchers conducted an ECG of the eyes of people who were suffering from depression and also on healthy individuals.
The results of the test showed that retinal contrast gain in the depressed patients was much lower. Also, an inverse relation between the severity of depression and the response of the retina was also seen.
According to www.independent.co.uk, the researchers now believe that depression works to change the person’s experience of the world around him.
People who suffer from depression are not able to judge the contrasts in the visual world. This is one of the factors that make the world a dull and less pleasurable place for them. The lead author of the health research was Dr. Ludger Tebartz van Elst and he believes that the further research needs to be done in this area.
He also said that “this method could turn out to be a valuable tool to objectively measure the subjective state of depression, having far-reaching implications for research as well as clinical diagnosis of and therapy for depression.”
