the Edge trainer
and Tennis Performance

Strengthening the Core Six Visual Skills provides the athlete with the foundational visual input needed to make critical decisions and motor responses at the highest level.

vision training
for tennis players

Tennis is a fast-paced game and requires athletes to possess excellent spatial awareness as well as the ability to read spin off a fast-moving ball. Players are continually challenged track the ball and operate on the edge of a line.

the core six
visual skills

Understanding an athlete’s proficiency in the six core visual skills allows players, coaches, and scouts to identify and correct visual weaknesses and enhance the athlete’s performance on the court.

  • Receiving Accuracy
  • Court Awareness
  • Spin Recognition
  • Anticipation

Convergence

Ability to pinpoint the ball on its approach and judge speed, trajectory and spin.

Divergence

Enhances a player’s spatial awareness and ball read off the opponent’s racket.

Depth

Judge in-game distances around the edges of the court and around the net.

Alignment

Focus on the play – enabling increased accuracy in their return game.

Recognition

Capture angles, pace of ball and opponents court position. Recall shot patterns and types.

Tracking

Anticipate where the ball will go and react quickly for an enhanced volley game.

Breaking Down
The Edge Score

The Edge Score is a comprehensive score given to each athlete based on their most recent evaluation. The score takes all visual skills into account – including convergence, divergence, depth perception, alignment, recognition and tracking. Through analysis of an athlete’s Edge Score as well as their individual scores, we identify areas of weakness and develop an appropriate training program.

CONVERGENCE

Convergence is the ability to focus on objects within close proximity and judge their movement and impact. Convergence may impact a player in the following ways:

  • Locate the ball as it approaches
  • Fast-paced play at the net
  • Process speed, trajectory, and spin

DIVERGENCE

Divergence is the ability to locate objects in the distance, impact an athlete’s ability to anticipate and react. Divergence may impact a player in the following ways:

  • Locate the ball off the server’s racket
  • Play baseline to baseline shots and estimate distance
  • Process the ball as it moves over the net

DEPTH PERCEPTION

Depth perception uses both eyes to locate objects in space to judge their distance, speed, and direction. Depth perception may impact a player in the following ways:

  • Locate the ball in space as you navigate the territory lines
  • Judge spatial awareness in net play
  • Proper positioning around the baseline

ALIGNMENT

Proper alignment creates no difference between the perceived location and actual location of an object. Alignment may impact a player in the following ways:

  • Reaction time
  • Timing at the net
  • Crisp and decisive movements

RECOGNITION

Recognition is the ability to observe, process and recall a series of visual targets, and respond properly. Recognition may impact a player in the following ways:

  • Recognize angles and pace of play
  • Pick up various shot types and angles of play
  • Follow opponent’s court position

TRACKING

Tracking allows you to process and follow an object while always monitoring all aspects of the game. Tracking may impact a player in the following ways:

  • Anticipate the action
  • React to topspin and drop shots
  • Track the shot through the air and anticipate the trajectory

edge trainer

The Edge Trainer is a web-based system that allows athletes to evaluate, analyze and train their six core visual skills. Regular training with the Edge Trainer improves the speed, coordination, and efficiency of an athlete’s eye movements, equating to improved timing, reaction speed, and accuracy on the court.
