Abstract

Background and Objective: The spatial distribution of urban services is a key factor in quality of life and the realization of spatial justice. Centers offering goods and services related to visual health, in addition to their economic role, are also important from a public health perspective. With population growth and the physical expansion of Ardabil city, the need for proper organization of these services has increased. The aim of this study is to investigate the spatial distribution pattern and service coverage of eyeglass retail units in the city of Ardabil using the relevant capabilities and tools in the ArcGIS environment.
Methodology: This research follows a descriptive–analytical approach, and data were collected through both documentary studies and field surveys. The statistical population includes all visual health service centers across Ardabil city. Spatial analysis was conducted using geographic tools within the ArcGIS environment.
Results and Findings: Out of a total of 38 identified units, 34 are located in Region 1, while Regions 4 and 5 lack any such services. Districts 1-1 and 2-1 show the highest concentration. Cluster analysis revealed that District 1-1, particularly Neighborhood 08-1, constitutes a hotspot with a 99% confidence level, indicating that service density there significantly exceeds the city’s average. This high concentration can lead to congestion and unequal access. In contrast, in the fourth to seventh rings away from the city center, no units have been deployed in these areas. The Nearest Neighbor Index (0.215602) confirms a clustered distribution pattern. Therefore, targeted expansion of these services in underserved areas is essential to promote spatial equity and improve access for all citizens.
