What I need my night vision for when I have a light that can turn a house like in full daylight??
And I tried to blind myself by standing 10 feet in front of a white wall with a stainless steel pistol in my hand and blasting the wall with a 2,000.000 candlepowers spotlight!! and can not blind myself
And in your scenarios the bad guy never have a flashlight, have dark adapted eyes and is is impervious to your light and always smarter.
People reading this thread don't have to take my word for it, you can make the test yourself if you have a white wall and a powerful light!!
