Evaluation of factors influencing eye lens radiation dose while using radiation protection glasses in interventional radiology: A phantom study.

Purpose: Radiation protection glasses reduce eye lens exposure in Interventional Radiology (IR). However, the protection ratio differs for the lead equivalent content and shape of the lenses. This study aimed to examine factors effective in reducing the lens dose by measuring the protection ratio of scattered radiation due to changes in the surgeon's face orientation, various lead equivalents, and shapes.
