الملخص	The OSDI is a 12-item symptom questionnaire designed to screen for and grade the severity of dry eye disease and other ocular surface disorders. Developed by Schiffman, Christianson, and colleagues (2000), it quantifies patient-reported ocular irritation and visual function limitations across frequency and impact domains. The OSDI is the most widely used screening tool for dry eye in clinical practice, clinical trials, and epidemiological studies worldwide.	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.
