1. Since the field of view through the VES-AF is narrow, like a tunnel or a keyhole, it can at first be challenging to find what you want to look at. To be successful, one must first look with your "normal" vision through the regular part of the eyeglass lenses, aiming directly at the object you want to see better. While looking directly at the target, slowly dip your head down, and look into the eyepiece of the VES-AF. With practice you should be able to switch between your normal vision and the telescope image quickly and accurately. Practice this at home while looking at objects on walls, faces of family, or the TV, until it becomes natural and you can do it easily. With time you can learn to ignore the tunnel field of view.

2. Looking at closer objects can be more challenging due both to the narrow field of view and the parallax (visual mismatch) produced by the VES-AF. To learn to find and touch objects within your arm's range, first find the object in the VES-AF field of view, and while looking at it, pass your upraised finger across the field of view several inches in front of the target. Once you can see both your finger and the target at the same time, watch your finger as it moves in to touch it. You MUST watch your finger while looking through the telescope to learn to do this. A convenient technique is to practice this while trying to touch the buttons on a telephone keypad.
