With each use, each time the black screen flashes in front of his eyes with a ball barreling out of a machine toward him, it sharpens his focus and, believes, strengthens his vision.

He’s not alone. “I loved them,” said outfielder, who wore them throughout the offseason when his dad, Ron, would throw batting practice to him.

“They absolutely do work, for sure.” The Nationals, organizationally, are big proponents of vision training.

Sitting at his locker in the Rogers Centre, Espinosa looks at a card with two photographs on it and a small baseball icon on each picture. The idea, he explains, is to focus your eyes so the two icons become one and a third picture appears, clearer than the first two.

In the past four games, Espinosa is hitting.364 with four doubles and two walks. Rick Ankiel, who often will focus on the letters in either shortstop Ian Desmond’s or Espinosa’s jerseys from center field and then zone back in on the opposing batter, said he prefers Espinosa’s cards over something like the Strobe glasses.

See how quick your eyes translated to your brain.” A few players shrugged off the suggestion, pointing out that if there was significant proof of the importance of vision training it’d likely be as mandatory as cardio or weight lifting is for the players. But they acknowledged there was probably no downside to the activities, especially the concentration it forces.
