1) Eye Movement Control: The ability to move both eyes together to point at an intended target or follow along a path, like a line of text.
2) Simultaneous Focus at Far: Forming a clear image of something in the distance.
3) Sustaining Focus at Far: Keeping an image of something in the distance clear.
4) Simultaneous Focus at Near: Forming a clear image of something close to the eyes.
5) Sustaining Focus at Near: Keeping a clear image of something close to the eyes.
6) Simultaneous Alignment at Far: Lining up both eyes at the same point the distance.
