概要	The Vision-Related Activities of Daily Living (Vision-ADL) Scale is a comprehensive instrument measuring self-reported difficulty with vision-dependent daily activities across a wide spectrum of vision loss severities. Developed by Massof, Stelmack, and colleagues at the Johns Hopkins Low Vision Clinic and VA Low Vision Service, the Vision-ADL employs adaptive item administration—presenting only vision-dependent activities relevant to the patient's functional level—to maximize responsiveness and precision across mild to profound vision loss.	The VF-14 is a 14-item, disease-specific functional status questionnaire developed to measure visual disability from cataract and its response to cataract surgery. Created by Steinberg, Tielsch, and colleagues (1994), the VF-14 focuses on difficulty with 14 common daily activities (e.g., reading small print, driving day/night, recognizing faces) and is used primarily to assess cataract severity, prioritize surgery, and document post-operative improvement in functional vision.
