Static visual acuity plays a significant role in football, as it helps players process and respond to visual information quickly and accurately.
Reading the defense or offense: Quarterbacks, in particular, need excellent static visual acuity to quickly scan the field and identify the positions and movements of defensive players.
Catching the ball: Wide receivers and tight ends rely on static visual acuity to locate and track the ball in the air, even when it is partially obscured by defenders or in low-light conditions.
Blocking and tackling: Offensive and defensive linemen need static visual acuity to identify their blocking assignments or locate the ball carrier.
Special teams: Kickers and punters require good static visual acuity to accurately judge the distance and angle to the goal posts or punt targets.
Sideline play: Coaches and players on the sidelines need static visual acuity to read the action on the field and make decisions about play-calling or substitutions.
Static visual acuity plays a significant role in baseball, as it helps players process and respond to visual information quickly and accurately.

Hitting: Batters require excellent static visual acuity to quickly identify the type of pitch, its speed, and its location as it leaves the pitcher's hand. This helps them decide whether to swing and where to aim their swing. Fielding: Infielders and outfielders rely on static visual acuity to track the ball off the bat, judge its trajectory, and position themselves to make a play. They must be able to locate the ball even when it is hit against a background of fans or stadium lights.
Pitching: Pitchers need static visual acuity to locate their target (the catcher's mitt) and precisely deliver the ball. They also use visual cues to read the batter's stance and adjust their pitch selection.
Base running: Runners need static visual acuity to read the defense and decide whether to advance, stay put, or retreat to a base. They must also be able to locate and track the ball to avoid being tagged out.
Coaching: Coaches in the dugout and on the baselines need static visual acuity to observe the action on the field, make decisions about strategy and substitutions, and communicate signs to players.
