Canadian scientists discovered that the quality of our eyesight depends on how we feel. It is covered in the article published in an issue of Psychological Science. In an experiment the volunteers were asked to look at remote images. Researchers found that those who felt positive were better at recognizing details of the images.
The research in this area was carried on by American scientists. They tested the eyesight of volunteers using a traditional eyesight test chart and then used a reversed chart where alphabet letters were arranged reversely, from smaller to bigger. The results showed that the eyesight of participants was sharper when they looked at the reversed chart.
The authors concluded that our perception of visual information directly depends on how unusual environment around us is. When we find ourselves in a non-standard situation our brand seem to instruct our eyes to see better.
