The Bulletproof Brain

High stress situations tend to push the operator into a tunnel vision state where peripheral vision is degraded, or lost completely.   Studies have shown that the part of the brain that is associated with peripheral vision (the Posterior Cortical Area) , is also associated coordination, reaction time, balance instigation of movement, performance of learned physical movements, spatial memory and mental fluidity.  This is also an area that is damaged in Alzheimers.  Tunnel vision, in essence, temporarily puts us in a state similar to that of Alzheimers.  Green Light Sights maintain peripheral vision keeping your brain functioning at it’s best under the stress of a gunfight.
