Good eyesight with the help of coffee

Numerous investigations on the impact of coffee on the human organism at last have good news. And at last doctors start to talk about the good impact of coffee on people's health.
According to recent investigations caffeine has the positive influence on the eyesight and increases the retina sensitiveness. Such conclusion was made by scientists from different parts of the world.
They put the experiment. Twenty four men with the good eyesight were chosen. All of them were young. During the experiment their eye sensitiveness was measured. In the result of measuring all men were divided into three groups. Then men of two groups got the pills with caffeine but in different dozes. And the third group got the pill without caffeine. It was made to control the sudden sensation changes.
In half an hour after pill taking doctors measured the sensitiveness of eye again. Men of the group that took the pill without caffeine didn't have any changes. The second group as well as third had some changes and the activeness of the eye increased with the doze of caffeine,
So, researchers proved that caffeine makes the retina react to the environment better. In the result the objects become brighter and have more colours and people start to notice invisible before details.
So, as you see the main human enemy in coffee may become the best human friend. The main thing is to know the doze.
