In the expression 6/x vision, the numerator (6) is the distance in metres between the subject and the chart and the denominator (x) the distance at which a person with 6/6 acuity would discern the same optotype. Thus, 6/12 means that a person with 6/6 vision would discern the same optotype from 12 metres away (i.e. at twice the distance).
Side view of handgun point shooting position. Point shooting (also known as target-[1] or threat-focused shooting, [2] intuitive shooting, instinctive shooting, subconscious tactical shooting, or hipfiring) is a practical shooting method where the shooter points a ranged weapon (typically a repeating firearm) at a target without relying on the use of sights to aim.
This means that as it propagates, it does not diffract and spread out; this is in contrast to the usual behavior of light (or sound), which spreads out after being focused down to a small spot. Bessel beams are also self-healing, meaning that the beam can be partially obstructed at one point, but will re-form at a point further down the beam axis.
A majority of tactical shooters have sight mechanics, where players are able to either "hip-fire" (fire without aiming the weapon's sights), which is less accurate but gives a wider view of the area; or "aim down sights" (ADS) for better accuracy, increased zoom, or an aiming reticle, at the cost of restricted visibility and camera sensitivity.
A tendency to focus attention tightly has a number of psychological implications, with it being seen as a state of "tunnel vision". While monotropism tends to cause people to miss things outside their attention tunnel, within it, their focused attention can lend itself to intense experiences, deep thinking, and more specifically, flow states.

At other times he runs the room, leading the audience, joking and shaking hands with thrilled supporters, in clear command of the moment. His gait is often stiff, but sometimes he jogs.
A study in 2017 aimed to find a way to reduce change blindness by making use of weapon focus. What they found was that the group of subjects that make use of weapon focus was less susceptible to change blindness when the change in the picture was a weapon they focused on. [24] This shows that weapon focus can be used in a less negative way.
Video of the terrifying incident ran on the station’s morning news program, capturing the sound of at least eight gunshots, then screams, and briefly showed Flanagan, 41, holding a gun.
