and hockey 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 hockey players

Hockey is a fast-paced and visually demanding sport. Skaters are challenged to move at high speeds while simultaneously tracking the puck and navigating opponents. Goalies must remain focused and aware at all times – being always prepared for one-timers and incoming shots.

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 ice.

  • Reaction Time
  • Puck Tracking
  • Goalie Skills
  • Spatial Relations


Improves ability to locate the puck while receiving passes and navigating defenders in one-on-one situations.


Enhances a player’s awareness, as well as their ability to operate in space and locate teammates when passing.


Impacts a player’s ability to judge in-game distances, lining up checks, redirecting shots, and pass and receive accuracy.


Improves player’s ability to focus on the play – enabling increased accuracy on one-timers and puck handling.


Allows players to read the play by recognizing the opponent’s offensive and defensive structure and positioning.


Allows players to anticipate and react quickly to shots, deflected pucks and passes while monitoring developing plays.

Visual skills and abilities can be evaluated, taught, trained and perfected. A number of Major/Minor League Teams as well as university programs have begun to evaluate and train these visual skills, utilizing new technology in order to improve their athletes’ performance on the ice.

Taking a look
at positions

Depending on the position an athlete plays in, the visual skills required for optimal performance vary. In hockey, an excellent defenseman may struggle with one-timers. This may be symptomatic of inferior convergence and tracking skills which are critical components to being a two-way defenseman, coupled with low divergence ability – which is the primary visual skill used in locating teammates the defensemen might be a liability in the attacking zone.


Talented forwards will possess a diverse visual skillset requiring the ability to locate incoming pucks then quickly adjust to find targets in the distance. This requires excellent flexibility between a player’s convergent and divergent focus. Enhanced recognition enables players to recognize patterns in defensive alignments and strategy while being able to scan the ice. Paired with strong tracking skills, the forward will be equipped to handle and redirect the puck to more effectively put it on goal.


Defensemen are required to skate with their head up to locate attacking skaters as they approach the zone – possessing strong divergence and recognition skillsets enable the defender to achieve proper positioning. Defensemen looking to make an impact on the attack will require excellent convergence skills in order to locate and move the puck effectively. A low convergence score could impact a player’s ability to connect on one-timers.


It’s no surprise goalies traditionally possess the strongest and most diverse visual skillsets in hockey. Strong visual flexibility (combination of divergence and convergence) enables the netminder to first locate the puck at a distance and follow it all way to the glove, hand, or stick. Improved recognition will enhance a goalie’s ability to recognize patterns of shooting and movement of skaters. Additionally, proper tracking will improve a goalie’s ability to track the puck throughout the play – including following the first save and enabling them to finish the play.

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 vision training program.


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:

  • Ability to connect on one-timers
  • Anticipate the speed and trajectory of the puck
  • Locate lower shots as they approach the goal (goalies)


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

  • Ability to pass and receive passes at far distances
  • Locating the goal while shooting from the perimeter
  • Ability to pick up skaters as they move into the attacking zone (goalies)


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:

  • Ability to line up checks and redirect shots
  • Locating pucks coming from a distance (goalies)
  • Judge in-game distances


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 as a goalie or skater
  • Crispness and decisiveness in movements


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:

  • Recognizing offense/defensive positioning
  • Track the puck following deflections (goalies)
  • Read play in all zones


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:

  • Reacting to deflections and passes
  • Anticipating the puck
  • Tracking the puck through the air as it approaches the net (goalies)
meet the
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 ice.
