If a player is a cross lateral the racket is invisible from the dominant eye for much of the swing.

如果选手是交叉侧重型，那么球拍由于大幅摆动，在主视野中不可见。

It works by setting up the dominant eye to focus far and the other eye to focus near.

它的工作原理是将主眼设置为聚焦远，另一只眼聚焦近。

This means that there is a bigger area of vision on the side where most of the action occurs. If a player is a cross lateral the racket is invisible from the dominant eye for much of the swing.

这意味着在多数运动发生的一侧有很大的视觉空间。如果选手是交叉侧重型，那么球拍由于大幅摆动，在主视野中不可见。
