In a highly stressful situation --- such as in a gunfight --- the shooter focuses on the target, with the brain funneling more blood flow to the center of the macula, which has a concentration of cones, that have a better visual acuity then the outer periphery motion sensing rods. This effect...can contribute to "tunnel vison".

After a shooter has finished engaging the target, it is recommended that the shooter should break the tunnel vison effect, by turning the head and eyes from side to side {with the brain sending more blood flow to the motion sensing rods}, to pick up any targets in your peripheral vison; so as to engage any bad guys that deserve it.
