Podsumowanie	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 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.
