Tóm tắt	The Low Vision Quality of Life Questionnaire (LVQOL) is a comprehensive instrument designed to measure the multidimensional impact of significant vision loss on health-related quality of life in individuals with low vision. Developed by Wolffsohn and Cochrane (2000), the LVQOL incorporates functional, emotional, social, and psychological domains and emphasizes measurement of disability and coping in populations with moderate-to-severe vision impairment where adaptive rehabilitation is the primary intervention.	The Impact of Vision Impairment (IVI) scale is a quality-of-life instrument designed specifically for patients with significant vision loss (low vision) to measure the psychological, functional, and social burden of visual impairment. Developed by Wolffsohn, Cochrane, and colleagues (2000), the IVI captures domains including emotional impact (distress, frustration), functional limitations (mobility, ADLs), social participation, and role fulfillment in populations with moderate to severe vision loss where generic or mild-vision-focused instruments are insensitive.
