Far from being harmful to eyesight, action games like Counter-Strike provide excellent training for what eye doctors call contrast sensitivity.
Contrast sensitivity is the ability to notice tiny changes in shades of grey against a uiform background, and is critical to everyday activities such as night driving and reading.
It often degrades with age.
Of course, excessive gaming or addiciton is bad!
BTW, it was also reported last year that surgeons trained or enhanced their pinhole surgery abilities by playing PS2 consoles.
As mentioned in my earlier posting on gaming, the whole family including my maid is now playing Bejeweled Twist and it provided some bonding amongst us. We also notice that Jason picked up the game very fast and his eye can see the pattern so much faster than us. After teaching us his strategies, all of us started to have very high scores now.
So do not condemn gaming totally as it is more of managing it well within the family even though it can be additive at times but with family support, it can be more of an entertainment and family bonding too.
Happy Gaming!

P.S. BTW, the community is supporting gaming as I just came across a gaming competition amongst schools at Funan IT Mall during the recent one week school holiday. One of the popular games now is World Tour Guitar Hero and it was the main feature of the tournament too.
