Contrast sensitivity is the capability to detect minute changes in shades of grey adjacent to even surroundings, and is crucial to routine activities such as reading or night driving. This ability is found to be degraded with age.

As in action games, players usually target and shoot figures which appear abruptly on a computer screen, the same phenomenon involves in the correction for at the level of the eye optics in order to achieve better contrast detection by glasses or laser surgery, one of the researchers explained.

“It is quite surprising that without making this correction by medical aid, we can help our brain to use the information effectively which is received from our retina”, the lead researcher said.

Now the most important question is how to put a limit on playing action games? In order to get benefits from these rather receiving harmful effects, because excess of everything can lead towards unwanted outcomes.

Parent s are openly discussing the issues of drug addiction with their children especially girls which are more eager to grasp the words. Now, with the prevalence of the awareness, about the harmful effects of the drugs, kids are more aggressively discussing with parent than the kids of the past, said Steve Pasierb.

In an annual survey, the number of kids, who stated that they are learning a lot from their parents’, raised from 32 to thirty seven percent compare to the last year. This is the first highest increase in the last 15 years.

“We were optimistic that kids who teach from their parents are less likely to use drugs than the kids who don’t get information from home,” Pasierb said.

The use of marijuana (the most common street drug) and methamphetamine has been reduced among the teenagers up to 30 and 40 percent, since 1998, respectively.

Parents discuss almost all types of drug range from alcohol to heroin with kids. Researcher also noticed that only 24 percent parents had discussed prescription drug abuse with children in comparison with 78 percent for pot and alcohol.

But the use of prescription drug likes painkiller and other OTC drugs was remain the same, parents think that it’s not an issue rather it’s safer than the illegal drugs.
