「パワークロスから結像図まで、屈折異常を視覚化する。」 複雑な乱視計算、もう迷わない。 数値を入力するだけで、強主経線・弱主経線の特定から結像状態のシミュレーションまでを一瞬で完了します。 ■ アプリの特徴 1. 瞬時に算出、強主経線と弱主経線 球面度数(S)、乱視度数(C)、乱視軸(Ax)を入力するだけで、瞬時に強主経線・弱主経線の経線角度と度数を計算します。国家試験の計算問題の答え合わせや、臨床での度数確認に最適です。 2. 直感的な「パワークロス」表示 計算結果をパワークロスで図示します。度数の分布を視覚的に捉えることができるため、乱視の構造がより深く理解できます。 3. 結像状態を可視化する「結像図」 入力された度数に基づき、網膜に対して焦点がどこに結ばれているか(前焦線・後焦線)を結像図として描写します。 近視性乱視、遠視性乱視、混合乱視の判別 最小錯乱円の位置関係 等価球面度数のイメージ把握 これらがひと目で分かるため、学生の学習効率を劇的に高めます。 4. シンプルかつスピーディな操作性 臨床現場や勉強の合間にサッと使えるよう、入力の手間を最小限に抑えたUI設計を採用。決定ボタン一つで、必要なすべての情報にアクセス可能です。 ■ こんな方におすすめ 視能訓練士を目指す学生: 国家試験の「屈折」科目の攻略に。 教職員・指導者: 学生へ屈折の概念を視覚的に説明する際のツールとして。 現役の視能訓練士: 複雑な処方や検査結果の再確認、新人教育の補助に。
