USING YOUR BIOPTIC TELESCOPE
Lining up your view through the telescope
Look first through the spectacle lenses. It should provide your customary distance vision. Look directly at the object you want to magnify. Drop your head slightly and look up into the telescope's eyepiece. You should see a full, round magnified image. You may have to focus it to get the image clear. Practice switching between the spectacle lens and the telescope until you can do it easily and without losing your target.
Locating what you want to see |
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.
Looking at close objects
Looking at closer objects can be more challenging due both to the narrow field of view and the parallax (visual mismatch) produced by telescopes. To learn to find and touch objects within your arm’s range, first find the object in the telescope's 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.
