Heavy drinking can cause blindness
Those who drink will easily ignore these objects appeared suddenly in sight, even if the alcohol content in their blood just half the allowable limit driving. Dr. Seema Clifasefi at the University of Washington in Seattle, US, said this phenomenon called blindness due to neglect, interesting science facts sometimes also occurs in people awake.
Alcohol is known to affect driving ability, reaction time and attention the picture, but so far no studies that explore its influence to blindness caused by distracted.
To investigate, the researchers gave 47 volunteers watch a video about the second group of players passed the ball through ball and ask them to count how many times the team wearing white shirts passed the ball.
In the video, a woman dressed as orangutans appears between the players, standing in the middle of the screen, slamming his hands on the chest, and then walked away some interesting facts. The participants were given a drink for about 5 minutes before watching the video. After watching, the researchers asked them not to see orangutans.

Among the sober, overlooking the animal 46%, compared with 18% among drunk.
“The results indicated alcohol was causing temporary blindness,” and the group concluded Clifasefi. “In our study, alcohol narrows attention to a small corner of a scene (counting volleyball), making other information in that scene (orangutan) easily overlooked” they say. In this case only a glass of hard liquor also makes you blind, additional groups… read more free online games for kids.
