Radiation shielding eye mask and method of use
An eye mask apparatus and method of use for protecting a patient's eyes during radiography has a lead vinyl sheet with a perimeter configured to completely cover the patient's eyes. The lead vinyl sheet has a first side and second side with a trim portion extending around the perimeter. The trim portion extends inward over the first and second sides. A retaining band coupled at a first attachment point and a second attachment point is configured to hold the eye covering portion against the patient's eyes when the mask is worn. To protect a patient's eyes during radiography, a lead vinyl sheet having at least 0.87 mm thickness, 0.125 mm lead equivalent value, and 2.18 kg/m 2 weight is provided and formed into a shape with the width at least twice the height to cover both eyes. The lead vinyl sheet is placed over the patient's eyes prior to radiography.
