Abstract
A focus adjusting tool used to perform an initial setting for a pair of autofocus eyeglasses includes an adjusting lens that refracts reflected light from a visual object, a housing including an inner space that allows a parallel movement of the adjusting lens, an adjusting unit that adjusts a position of the adjusting lens inside the housing, and a first end and a second end in a moving direction of the adjusting lens. The first end is provided with a hole for visually observing a visual object through a power variable lens of the pair of autofocus eyeglasses. The adjusting lens adjusts, in response to the position thereof inside the housing, an incident angle of the reflected light from the visual object into the power variable lens, the visual object being located on the side of the second end.
