Strong wine can cause blindness
 Someone drinking wine can overlook all objects that suddenly appear within eyeshot,even the level of alcohol in their blood equals a half of the limited level of driving
Doctor Seema Clifasefi in Washington University,Seatle,USA said that this phenomenon was called the blindness of inattention ,and sometimes it also happened to wide awake person.
We know that alcoho always has an influence on driving ability, reactive time and image attention,but until now ,no research have found out about its influence on the blindness of inattention .
To investigate, researchers let 47 volunteers watch 1 video of 2 groups of football player passing the ball to and fro and requested them to count how many times the white pullover group passed the ball.
In this videotape, 1 woman in orangutan clothes appeared in the center of all football players and the screen, beat her chest and went away
All participants were let have a kind of drink 5 minutes ago when they watched this video.When the video finished, researchers asked them if they had seen a orangutan
A half of them were let drink false alcohol, the others were let drink vodka and tonic to increase the level of alcohol in their blood to a half of the limited level of driving.
A half of each group were inform that they had drunk alcohol, the others believed that their drink didn't contain yeast substance.
Who knew that they themselves had drunk alcohol also informed that they felt drunker,even when they drank false alcohol. But even though they were informed if they had drunk alcohol or not,their abilities to recognize the orangutan was not related.
In total,1/3 of them didn't recognize the orangutan. Among wide awake persons,46% of them could recognize it compared with18% of drunk group.
"The result demonstrates that alcohol causes temporary blind state", Clifasefi and his group concluded. "In our research,alcohol restricts the attention to a small corner in one sight (counting times of passing the ball) and let other object in this sight ( a orangutan) be overlooked easily",they said
In that case,just a glass of strong wine also make you blind, the group added.
So,you should control your self with strong wine.That doesn't only prevent you from blindness but also from an influence on driving ability, reactive time and image attention.
