To provide a technique for completing the initial setting of the dioptric power of a dioptric power variable lens without re-installing of a visual observation target by a user.SOLUTION: A focus adjustment tool for the initial setting of auto-focusing spectacles comprises: an adjustment lens 301 which refracts reflection light from a visual observation target; a housing 300 which includes an interior space for the parallel movement of the adjustment lens 301; an adjustment part 304 for adjusting the position in the housing 300 of the adjustment lens 301; and a first end and a second end 303 in the movement direction of the adjustment lens 301. A hole for visually observing the visual observation target via a dioptric power variable lens 101 of the auto-focusing spectacles is provided on the first end. The adjustment lens 301 adjusts the incident angle to the dioptric power variable lens 101 of the reflection light of the visual observation target arranged on the second end 303 side in accordance with the position in the housing 300.SELECTED DRAWING: Figure 4 【課題】ユーザーが目視対象を設置し直すことなく度数可変レンズの度数の初期設定を完了するための技術を提供する。【解決手段】オートフォーカス眼鏡の初期設定のためのフォーカス調節ツールは、目視対象からの反射光を屈折させるための調節用レンズ３０１と、調節用レンズ３０１が平行移動するための内部空間を含む筐体３００と、調節用レンズ３０１の筐体３００内の位置を調節するための調節部３０４と、調節用レンズ３０１の移動方向における第１の端部および第２の端部３０３とを備える。第１の端部には、オートフォーカス眼鏡の度数可変レンズ１０１を介して目視対象を目視するための穴が設けられている。調節用レンズ３０１は、筐体３００内の位置に応じて、第２の端部３０３側に配置された目視対象の反射光の度数可変レンズ１０１への入射角を調節する。【選択図】図４
