תקציר	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 NEI-VFQ-25 is a 25-item self-report questionnaire measuring the impact of vision loss on health-related quality of life across multiple functional and psychological domains. Developed by the National Eye Institute (Mangione et al., 2001), it is the most widely used vision-specific QoL instrument in ophthalmology and serves as the gold standard for quantifying patient-reported visual disability across diverse eye conditions.
